A quicknote from SUPSALV this issuefocuses on NAVSEA’s effortsto support Diver safety andfleet priorities.First, our team haslogged many weeks awayfrom homeport since ourlast issue supporting theintroduction of diver lockin/lock out facilities aboardthe SSGN and VIRGINIAClass submarine programs.Due to a focused team effortby the submarine crews, NAVSEA 00Cand a host of stakeholders from bothsubmarine programs, the Navy and thewarfighting commanders worldwide havea more robust ability to insert SpecialForces covertly in the war on terror. Thefirst submarines from both programs arenow certified and are proceeding towardtheir first operational deployments.SUPSALV’s efforts will continue withthe certification of the follow ships fromboth programs.Similarly, SUPSALV direct supportfor fleet operations included efforts arehighlighted by a number of articles inthis issue. Salvage efforts associatedwith the departure of the USS EMORY S.LAND from La Maddalena, Italypresented an excellent opportunityto utilize the ORCA to support inwater decompression with oxygen.This high visibility operation dictatedthe diving profiles for which the newair diving decompression tables wereintended. SUPSALV provided directtraining, certification, and materialsupport that enabled the tremendousaccomplishments of the Emory S. LandDive Locker, MDSU TWO detachments,and other dive lockers to salvage tons ofaccumulated debris.Captain Rich HooperCenterfold .................................................... 14ORCA Update .............................................. 16MDSU ONE Receives U.S. Coast GuardMeritorious Unit Commendation .................. 17Deep Submergence Unit Diving Capabilities 18Atmospheric Diving Systems 2000 (ADS) ... 19Salvage of the “Widow Maker” .................... 20A number of notable diving missionsare also documented in this issue includingsalvage efforts on twosubmarines.

In January of 2007, USS NEWPORTNEWS had a collision at sea with acivilian tanker, Mogamigawa, in theStraits of Hormuz. The Mogamigawa, aJapanese owned tanker, was built in 2001and is classified as a Very Large CrudeCarrier (VLCC). This super tankerdisplaces 300,000 tons of water, 3 timesthe amount of water of a modern aircraftcarrier. USS NEWPORT NEWS displaces6,900 tons of water. The tanker’s bladecaused extreme structural damage tothe Main Ballast Tanks (MBT) on thestarboard side of the submarine. Eighteendamaged areas were found, sixteenvertical gashes and two large dented areas.A quick response dive team fromUSS FRANK CABLE responded onscene to begin the damage assessment.Additional dive teams and personnel fromNAVSEA 00C5, Phoenix International,USS EMORY S. LAND, and SWRMCwere dispatched to assist with voyage repair.When USS FRANK CABLE diveteam arrived on site in early January, theybegan by mapping out the damaged areain order to form a complete picture of theoverall damage.This mapping was to be used toformalize a repair approach. The entireNavy dive team, lead by MDV ClouseUSS FRANK CABLE (AS 40) Diver returns from Ballast Tankinspection.USS FRANK CABLE (AS 40) Divers before in-water damage assesment.of USS FRANKCABLE begantemplating theentire damagedarea (40 ft. by17 ft.) with herculitecovers.The use of theherculite coversas a templatewas a uniqueand clever idea.We were ableto get accuratemeasurementsof t he extent ofthe damage belowthe waterline.This newinformation wasprovided to Newport News Shipbuilding,the planning yard, so it could be incorporatedinto a finite element analysis of theship’s structure.Five days were spent performingvideoed inspection dives so all repairactivities stateside could form a completepicture for structural analysis repair options.The original repair approach involveda bolt on plate design for all damagedMBT area below the waterline. After furtheranalysis this approachwas deemed not structurallysound. The next plan was toreturn a certain percentageof ballast control by wetwelding doubler plates overcertain areas (Tears 1-4). Toincrease the structural support,5 doubler plates werewelded over tears 9, 12-15.Additionally stiffeners werewelded below tears 5 and 7.The wet welding wasperformed by Phoenix InternationalIncorporated (PII)Divers. Phoenix Dive Supervisor,Lance Shupe, was thelead supervisor for both day and night PIIdive crews. He also was the primary onsiteadvisor for the doubler plate configuration.His repair knowledge coupled withthe PII engineering team back in Largo,MD, and the structural requirement directivesfrom NAVSEA 05P made it possibleto properly design, size, and shape all ofthe doubler plates. PII, NAVSEA 00C5,and NAVSEA 05MP2 determined the appropriatewelding procedure and weld sizefor strength concerns.USS FRANK CABLE dive locker,Phoenix International, USS EMORY S.LAND dive locker, and the SWRMC deltacrew, worked around the clock removingspecial hull treatment (SHT), rigging andremoving metal debris, and grinding andprepping the damaged area for welding.Torpedo tubes 1 and 3 shutter doors wererigged and removed and 300 ft 2 of SHTwas removed.The U.S. Navy dive team recorded500 hours of bottom time.PII recorded 430 hours of bottom timeand 212 pounds of nickel electrode wereconsumed for a total of 117.7 linear feetof weld.A p r i l 2 0 0 8 3

Upon completion of allwelding and initial NDT,USS NEWPORT NEWSconducted at-sea tests whichincluded an emergency blowto insure the safety and completenessof all repairs. Anadditional visual inspectionwas conducted upon theship’s return to the forwarddeployed site. All welds weresound and all doubler platesand stiffeners intact. A temporarySUBSAFE certificationwas given to the ship andshe sailed back to homeportfor permanent repairs.The total repair time forUSS NEWPORT NEWS wasover 60 days. It was the firsttime such a robust repairwas undertaken in such a locationwith so many teamsinvolved. All four dive teamsworked and performed asone team. All teams becamea cohesive unit that worked and performedoff of each other’s work and made the entireevolution an outstanding success.The fact that we were able to weldsuch large doubler plates over a contouredarea was a special feat. This was somethingthat had not been performedbefore. Plates A and B (forward twoRepair Team; NAVSEA, USS FRANK CABLE, USS EMORY S. LAND, & PII.doubler plates), were the largest doublersthat NAVSEA had installed on a submarine.Most doublers plates are 1 ft by1 ft. By the end, we had partially or fullyrestored MBT’s 1, 2, and 3 functionality.This permitted a successfulsubmerged transit for USS NEW-PORT NEWS.The damageassessment, repairs,and re-certificationof USS NEW-PORT NEWS wasa combined effortfrom entities allacross the globe.The dive teams wereat the forefront ofthe global effort,providing the onsiteeyes and manpowerto evaluate, repair,and return the ship to limited service fortransit back to its homeport.This collision sparked a review ofemergent voyage repairs for our submarineassets. NAVSEA is currentlyresearching the design of a fly-awaykit for SHT removal, underwater mapping,and underwater metal cutting. Thiskit will greatly assist the proper andefficient assessment of underwaterdamage so an accurate and completetechnical review of repair options can beconducted.LCDR Carl Parks is an EngineeringDuty Officer/ Diver currently working asa Project Manager at the UnderwaterShip Husbandry Division at NAVSEA00C in Washington, DC.ND1 (DSW/SW) Williams work on SHT removal and mapping.4 A p r i l 2 0 0 8

From 9-22 July 2007, Seabee Diversand support personnel from UnderwaterConstruction Team ONE (UCTONE), based at Naval Amphibious Base(NAB) Little Creek, VA deployed toOdessa, Ukraine to participate in themultinational training exercise SeaBreeze 07 as an element of the MaritimeComponent Commander of CTF 167.In its tenth year, Exercise Sea Breezeinvolved 13 different countries withover 2,400 participants includingnearly 750 U.S. Navy, Marine Corps, andArmy personnel. The annual EUCOMPartnership for Peace exercise focuseson NATO interoperability of maritime, air,and ground task forces in addition topeace support operations for the BlackSea Nations such as Ukraine, Moldova,and Turkey.UCT ONE’s mission was to trainDivers from the Ukraine Mobile DivingUnit, Latvia Explosive Ordinance Disposal,and Macedonia Combat DivingUnit in surface supplied diving operationsand underwater cutting/welding techniques.EO1(SCW/DV) James Igoe of AirDetachment Charlie,UCT ONE, was the exerciseplanner and wastasked to deploy to theWestern Naval Base inUkraine with 20 tons ofgear to include the MK-III Lightweight DivingSystem for surface supplieddiving, underwatercutting and weldingequipment, hydraulictools, side scan sonar,and a Remotely OperatedVehicle (ROV). Heensured that all 47Divers were trained andunderstood the rigoroussafety procedures that had to be followedin order to have a safe and productivetraining exercise. All foreign Divers at-tended classroom training covering thediving and underwater construction techniquesthat are used by the UCTs. PettyOfficer Igoe stated, “Previously I haveparticipated in three multinationalDIVEX’s in easternEurope, so I was veryexcited to be given theopportunity to planand return for a fourthtime. It’s always niceto see familiar facesand work with friendsI have made over thelast few years. As alwaysthis DIVEXwent off without ahitch, thanks to thehard work and trueprofessionalism of allthe participants.”The language barrierwas eliminatedthanks to the assistance of our translator,Sergeant Igor Zolotushkin, from the DefenseThreat Reduction Agency (DTRA).He interpreted all diving subjects and diveside terminology which greatly increasedEO1 (SCW/DV) James Igoe exiting water.the learning process allowing for more inwater training time for the participants.When asked about his participation, SergeantZolotushkin replied, “Great exercise.Sea Breeze 2007 exercise was a greatexperience for me as an interpreter andas an NCO. I’ve gotten a lot of greatSSTG Ivars Kuznecovs (Latvian Diver) entering the water.practice and useful experience by workingwith the U.S. and national dive teams.”To increase training value and utilizeall diving skills and equipment, severalrealistic scenarios were employed, such asretrieval of a downed helicopter, locatingand recovery of jettisoned ordnance, andrepair of pier side piping system damagedby exploding ordnance. Once the foreignDivers completed the classroom phase,they performed a dive with a qualifiedUnderwater Construction Technician toensure they understood the procedures andfamiliarize them with the equipment suchas the MK-21 diving helmet in the water.During the pier-side operationalphase at the Western Naval Base, the divesstarted at 10 feet for gear familiarization,progressing to underwater cutting andwelding. While some Divers were workingpier side in the water, other Diverswere involved with using side scan sonar,which is used to identify objects on thesea floor. This training proved even morevaluable when they located a sunkenboat inside the harbor in addition to the(“SEABEES” continued on p. 6)A p r i l 2 0 0 8 5

(“SEABEES” continued from p. 5)training project. The remote operatedvehicle (ROV), which has two camerason board, was then used to viewships underwater. Following thatevolution, the bathymetric systemwas used to identify the depths andslopes of the sea floor bottom toverify contours and bottom profile.Another test of interoperabilitywas communications. The UCTtechnicians did a fantastic job ofmaintaining the mission criticalSATCOM, HF, and VHF nets duringthe entire exercise to transmitall reporting requirements to theCTF 167 headquarters at the WesternNaval Base, the Maritime ComponentCommander embarkedaboard USS DONALD COOK(DDG 75), and other various U.S.and foreign units. In addition tothe diving scenarios, we included acommunications related scenario to conducta contingency related damageassessment of a pier facility and transmitdata for further engineering analysis. Wesuccessfully accomplished this reach backcapability via INMARSAT transmissionto NAVFACLANT, Contingency OperationsEngineer Division in Norfolk, VAto analyze the data and provide a notionaldesign for the repair. This reach back capabilityexercised our ability to communicateacross the globe from anywherein the world for contingency engineersupport during any hour of the day ornight. We received positive responseswithin minutes of transmission. Thanksto James Gale and his staff atNAVFACLANT for their assistanceand prompt responses.LCDR JurijsTimofejevs,CommandingOfficer of theLatvia ExplosiveOrdinance DisposalDivingTeam explainedhis goals. “Thisis the 5th DiveEx we have beeninvolved with,three in Baltic,one in Georgia,and this one inUkraine. Ourgoal is to trainto dive in hotweather environment and to trainUkrainian Divers, with rebreathers.Also participate in surface supplieddive training and underwater cutting andwelding with the UCT Divers”.EA1 (SCW/DV) Sang Park instructs Divers from Ukraine, Latvia andMacedonia while SGT Igor Zolotushkin, U.S. Army, interprets.CPT FillipCvetkoski, CommandingOfficerof the MacedonianSpecial ForcesSCUBA divingteam, was veryhappy with thetraining. “Fivestars for the SeaBreeze exercise!This is more thana great thing forall of us fromthe Macedoniandiving team. We,the Macedonian“Wolves”, are verymuch excited tobe here and workwith all of theDivers from the USA,Ukraine, and Latvia.This is a very new way of diving for us,but with all of the help and teamwork thatwe get around here, everything is so easy.Everything is perfectly organized, safe towork, and it is just the right place and theright time for everybody to be here. All ofus working here together, we unselfishlycombine and share to each other theexperience that all of us have, and in thisway we learn more and more every day.We also do have some fun working andmade a lot of new friends every day. Atthe end “Two thumbs up” for everythingand I hope that we will continue themutual cooperation in the future!”As Sea Breeze progressed, so didthe depth and complexity. While at 80feet of seawater in the Black Sea, embarkedaboard Ukraine based ship UPNKREMENETS, the previous tasks wereperformed in addition to light salvageoperations using underwater liftinggear. As training for the downedhelicopter scenario, the Divers movedmore than 1000 pounds of concrete andsteel along the bottom with lift bags andused underwater hydraulic tools to drill,grind, and hammer. This proved challengingbut successful. The diving experienceat sea was the pinnacle of the coordinationefforts for all four nations involvedand cemented our bonds as divingEA1 (SCW/DV) Sang Park conducts pre-dive brief to intergrated multinationaldive team.6 A p r i l 2 0 0 8

Complete interoperabilitywas achieved.“Sea Breeze 07 has been a uniqueopportunity for a variety of Sailors, Airmenand Marines from around the globeto train and operate together. The Diverswere a combination of Ukrainian, Latvian,Macedonian and U.S. (UCT ONE). Theyfound that even though their language andequipment were somewhat different, withtraining and a little help from assignedinterpreters, they were able to achieveinteroperability. As it turned out, a Diveris a Diver, regardless of nationality,” statedCDR Daniel Daglio, Fleet Diving LiaisonOfficer from NAVEUR for CTF 167 duringSea Breeze 07.In closing, the exercise was a successfulmission. LCDR Daniel Stoddard,Commanding Officer of UCT ONE, wasgrateful for the hard work and dedicationby everyone. “Sea Breeze 07 was a resoundingsuccess thanks to the unparalleledcooperation and participation by theUkrainian, Latvian, and Macedoniandiving units. I would also like to commendAir Det Charlie for their detailed planningleading up to and incredible professionalismduring the exercise…a truly fantasticeffort by everyone. Additionally, theamount of knowledge transfer from myDivers to the other countries involvingnew diving techniques, equipment, andtechnology was tremendous. Many newfriendships were created along withprevious friendships renewed. Inthe spirit of the Partnership for Peaceprogram, I know the positive impactsof the enhanced interoperability willbe felt for many years to come. As theonly NCF unit to participate in SeaBreeze, my Seabees were not only ashining example of the great things theUCTs do daily, but also fully demonstratedthe Can Do spirit resident inevery Seabee. I am extremely proud ofthem,” stated LCDR Stoddard.If you are interested in SeabeeDivers, please visit https://www.seabee.navy.mil/.LCDR Daniel M.

For 35 years the U.S. Navy stationed asubmarine tender at the Italian Navybase on the island of Santo Stefano inthe La Maddalena Archipelago NationalPark, located directly off the north eastcoast of Sardinia. In light of the impendingbase closure it was decided inDecember 2005 that prior to the departureof the last U.S. Navy vessels it would beappropriate to clean the debris from the seafloor and leave the harbor floor in a conditionbefitting a national park. Soon, thisnoble, and seemingly modest, idea wouldturn into the largest salvage and recoveryoperation of underwater debris since WorldWar II.Initially, the decision was made to utilizeDivers attached to USS EMORY S.LAND (AS 39) in order to complete themission. However, this quickly proved tobe a case of over optimism. The first snagappeared early in the operation as plannersrealized that the primary mission of USSEMORY S. LAND (AS 39) Dive LockerMDSU TWO Diver prepares to go to work.was to support submarines and other SixthFleet ship repair, not salvage recovery.More importantly, following detailed reconnaissancedives of the debris field thetrue scope of the job became apparent - a14-acre industrial-style junk yard was sittingunder 135 feet of sea water, and someserious help was going to be needed tocomplete the mission.Following the resolution of budgetconstraints, help finally arrived when adetachment from Underwater ConstructionTeam ONE and anOcean Facilities Programofficer from the Naval FacilitiesEngineering ServiceCenter (NFESC) took onthe task of a detailed bottomsurvey. This team attackedthe task of completinga bathometric and sidescan sonar survey of theharbor area, in addition totaking video footage alongthe seafloor with the use ofremotely operated underwatervehicles. Their effortsprovided a critical visualpicture of the extent of thedebris field, the undersea terrain, andconfirmed that additional help wasneeded.In June 2007, more assistancearrived from Mobile Divingand Salvage UnitTWO. Eighteen Salvorsin the form of a MobileDiving and SalvageCompany led by CWO2Dale Kasztel and NDCM(MDV) Arne Phillipswent to work. At thispoint, since all wereaware of the scope ofthe job, USS EMORYS. LAND (AS 39) DiveLocker was assigned thedebris removal operationas their only mission.Additionally, a four-mancompany from Explosive OrdinanceDisposal Mobile Unit EIGHT assistedwith hyperbaric chamber support andLCDR Jeff Mathis was assigned asOfficer in Charge of the entire operation.Fortunately, Poseidon was smilingdown, when CWO3 Ray Schubert andNDCS (MDV) Rotan joined the team.Typical debris field.With this combined team of diving andsalvage experts the decision was made toutilize one shore-based and one sea-baseddive side working, simultaneously; themission would be completed mid-December2007. The one problem with the planwas that there was no platform from whichto set up the deep-water dive side, no assetin La Maddalena, and nothing readilyavailable in or out of theater. The answerto this issue was to have the folks at ESSMLivorno and Cheatham Annex design andbuild a suitable platform. The finishedproduct consisted of a 100 ft. x 30 ft. bananabarge with a hyperbaric chamber(FARC) and Morgan Crane to be used asthe required diver’s davit.A major constraint to achieving aquick clean up is that the island of SantoStefano is an Italian national park, so nodredging equipment could be used andevery effort had to be taken to minimizedisturbing the bottom which basicallymeant each item had to be picked up byhand. Simultaneously, the shore-baseddive stations from MDSU TWO had tobe customized by manufacturing laddersto fit various pier side insertion/extractionpoints while lifting points capable of holding10,000 lbs. (when filled) salvage basketshad to be identified in order to conductrecovery operations. The Divers used8 A p r i l 2 0 0 8

lift bags to move the baskets up and downthe slopes into these identified areas.Some of the slopes went from 55 fsw to110 fsw and many times the 5K lift bagswere filled to capacity and debris had tobe removed to facilitate the up and overphase. A majority of the diving was accomplishedusing a descent line in depthsdown to 120 fsw but there was plenty ofstage diving to be done as well. The divesupervisors flexed their watches whileusing both standard air and SURDO 2decompressiontables while completing thetransition to the VVal-18M tables whichprovided much appreciated flexibility forthe supervisors.Additional forces arrived in mid-August when USNS GRASP (T-ARS 51)arrived on-site with MDSU DET SIXembarked. Det SIX quickly commenceddiving operations with a second deepwater dive side from GRASP fantail whichcorresponded with a flurry of activity withthe bottom line being the shifting of theend date by two months. There would nowbe 75 Divers working simultaneously onfour dive sides with four separate craneequipped dive platforms. An LCM wasconverted into a garbage scow so it couldrotate between dive sides to pick up anddrop off salvage baskets, two 80-ton piercranes and three forklifts were constantlycarrying debris-filled salvage basketsdown the 30 ft. wide pier to properlydispose of the refuse. As the work tempoGrided survey area for LaMadd Harbor cleanup.Picture of typical bottom.picked up, support personnel from USSEMORY S. LAND and NSA LaMaddwere utilized and NAVFAC EURSWAbrought in the Crofton Divers and ShawEnvironmental for technical assistanceand additional resources. The three pillarsof the salvage community, MDSU,NAVSEA and independent contractorswere in full swing.With everything in place, on 7September 2007, Operation Catfish lit offfull steam. It was intense. On average, 75Divers dove to their maxlimit everyday to depths of130 ft. Each available Diverdove: Second Class, FirstClass, DMTs (it’s true),MDVs, Diving Officers, andDMOs. The team recoveredan average of 23,000 lbs. ofdebris per day; scanned it forradiation, and the processcontinued through missioncompletion on 27 September2007, three days ahead ofschedule.Operation Catfish was atruly unique event. The diveoperation had many obstaclesto overcome and itssuccess is attributed to all personnel whoparticipated. This was also the first timeseven decompression chambers were locatedon one site in continuous operation.Almost every community in the divingNavy was represented: Salvage, OFP,EOD, UCT, Medical, civilian Navy, andNEDU. Their combined hard work ensuredthe largest salvage project sinceWW II was a success. Fourteen acres and1,147,594 lbs. of debris removed, 1,415incident free dives totaling 1,311 hours ofbottom time and a total of 88,000 manhours expended during the operation.Items picked up from the bottom rangedfrom Military ID cards from the 1990s to5,500 pound steel pier structures.People ask what the most HOOYAHitem found was …well being DEEPSEAI have to say the MKV dive boot has thatdistinction.

On May 1, 2007, SWRMC Divers(Code 990) commenced waterbornerepairs on USS RONALD REAGAN(CVN 76) to include installation of 36(200 lbs. -1000 lbs.) separate largecofferdams with NAVSEA 00C5 floodingsensors, wet welding zinc anodesonto sea chests in various location, wetwelding two large ropeguards, single valve repair/replacement standby diveteam and replacementof two of four 32-tonpropellers.The complexities ofsafely removing and reinstallinga propeller of thismagnitude while underwateris difficult at best,and conducting two waterbornesimultaneously isunprecedented on theWest Coast. This repairwork was expertly supervisedand manage byNDCS(MDV) AnthonyShepard, NDC(DSW)Grady Morris, andND1(DSW/SW) KenMcCormick of SWRMC dive lockerCode 990, and Mr. Jack Meirs of PugetSound Naval Shipyard (PSNS). They superblyled a 25-person dive team consistingof SWRMC, PSNS and militaryDivers from Yokosuka, Japan, and Everett,ND1 McCormick briefs SWRMC Diver NDCS /MDV TonyShepard and PSNS Diver DW Adams prior to the nextwaterborne rigging evolution on USS RONALD REAGANdouble propeller change out.WA, during one of the most complex UnderwaterShips Husbandry (UWSH) repairsattempted by West Coast Divers.NAVSEA 00C5 UWSH on-site representativewas Mr. Scott Heineman who providedsuperb technical oversight duringthese arduous and technically difficult propellerreplacement evolutions.SWRMC Code 990 Divers along with PSNS dive and NAVSEA 00C5 UnderwaterShips Husbandry representative Scott Heineman take time before Divers enterthe water to commence rigging the new propeller for USS RONALD REAGAN.Divers first set up various tools andheavy rigging equipment on a 34-foot by100-foot YC barge requisitioned fromNAVSTA, San Diego, CA with an assortmentof NAVSEA 00C5 UWSH andrented equipment to support this hugeundertaking, including a smallcrane to transport gear from thebarge to the waters edge, a uniquefloodable CONEX box and liftingbeam used to counter balancethe weight of the propeller as itwas transferred to and from theshaft to the barge, and pneumatictuggers used to transport gear toand from the work site utilizingrigging tunnels and snatch blocks.Divers from SWRMC Code 990wet weld crew first removed ropeguards utilizing hydraulic grinders.This allowed access to thegland seal ring. Next SWRMCCode 990 Alpha and PSNS Dive teamremoved fairing plates from the dunce capand placed a balance beam and a five tonchain fall to assist in removing the duncecap.Once the ancillary gear was disconnected,the boss nut (used to secure thepropeller once pressed on) was removedfrom the shaft utilizing a mechanicallifting bridle andthe pilgrim nut method (hydraulicpress) gear was positionedusing the same liftingbridle utilized to removethe boss nut from the shaft.The pilgrim nut was threadedonto the shaft and dual threefoot by four inch studs werethreaded into the propellersaft hub face. A five-ton backingplate was rigged in conjunctionwith the studs andtwo 20-pound fasteners wereused to secure the plate inplace against the end of theshaft. The pilgrim nut waspositioned against the backingplate and pressurized inintervals up to maximum designedpressure to unseat the propeller offthe shaft taper. Numerous attempts byDivers to unseat the propeller provedunsuccessful to the point that explosivesbecame the last option to successfullyremove the propeller.This endeavor required many meetingswith USS RONALD REAGAN,PSNS, COMAIRPAC, NASNI andNAVSEA; e-mail exchanges and numerousnaval messages written and answeredto ensure the explosive event went offsafely as planned. Navy Divers successfullyused less than half a pound of primadetonation cord in conjunction with thehydraulic pilgrim nut to unseat the propellerfrom the tapered shaft (the forceimpact from the explosion shocks thepropeller while the pilgrim nut applieshydraulic pressure on the propeller). Afterthe explosive event, the pilgrim nutprocedure was operated two more times1 0 A p r i l 2 0 0 8

USS RONALD REAGAN damaged propellercoming out of the water as Divers look on.bringing the propeller off the shafts taper.The pilgrim nut assembly was replacedwith heavy rigging (two 50-ton chainfalls)for the next stage of the evolution, removingthe propeller.Divers positioned the 50-ton chainfalls onto two lifting tunnels built in USSRONALD REAGAN’s hull design specificallyfor the purpose of propeller replacement.These heavy rigging pieceswere used to take the weight off the shaftand yard and stay the 32-ton propellerslowly the Divers YC barge. The term“Yard” (to move) the propeller from theshaft, off the tapered end and onto a prepositioned50-ton chain fall “STAY”,which was rigged onto the heavy liftingbeam which was positioned on the YCbarge with the floodable CONEX box(counterweight). During the transfer ofweight from USS RONALD REAGANshaft to the YC, the empty CONEX boxwas filled with 80,000 lbs. of water, safelycountering the 32 tons of weight transfer.Once the weight had been successfullytransferred to the Divers YC barge, thebarge was carefully towed with the oldpropeller secured just 10 feet below thewater line to NASNI Kilo pier forswap out with the new propeller. Afterthe new propellers arrived they werevisually inspected and “Ready for Issue”(RFI) and installation on USS RONALDREAGAN’s shafts.The damaged propellerwas rigged off the bargeand the new one set inplace on the lifting beamwhich had a 50-ton chainfallrigging to receive the32-ton propeller. This allowsto Divers to move the propellerfrom the barge to the50-ton chain-falls rigged insaddles above the shaft(Yard and stay). The bargewas moved back into placeutilizing NASNI Port OperationsPusher Boats ontothe starboard side of USS RONALDREAGAN. As the new propeller wasrigged in place the removal process isreversed as the new propeller was carefullyrigged onto the shaft using the 50-ton chainfalls. This evolution requiresextreme skill by Divers on-site, damageto a keyway or the threaded shafting(wrapped with fiber line and lead sheeting)can set back the diving operationsfor days if not weeks. The new propellerwas walked up the shaft onto the taper.However, after the pilgrim nut (usedto push the propeller onto the shaft andseat it) was pressed up and retracted, thepropeller followed the hydraulic press(pilgrim nut) back down the taper. Numerousattempts to press the new propelleron the shaft proved unsuccessful. Afterconsulting with NAVSEA and PSNSengineers, number one propeller wasremoved and placed back on NASNIKilo pier. Divers then shifted their effortsto removing the number four propeller,which was much more cooperative andcame off using the pilgrim nut procedure.The new number four propellerwas safely rigged onto the shaft andsuccessfully pressed on after 10 days ofarduous diving in near zero visibility,with heavy currents and five-foot swellsfrom passing ships. This evolution wasa testament to the skill and determinationof the SWRMC and PSNS Diversworking on USS RONALD REAGANto ensure this job was successfully andsafely completed.Divers enter the water to commence rigging the new propellerfor USS RONALD REAGAN.In the meantime, number onepropeller was cleaned using pressurewashers and the shaft power washed andscrubbed as the propeller change outbarge rigged the new propeller onto thelifting beam and was moved into positionon the starboard side of USS RONALDREAGAN. The propeller was rigged andsuccessfully pressed onto the shaft taperwithout incident using the heavy rigginggear and pilgrim nut.After 37 straight days of workingfor 12 to 16 hours with heavy waterbornerigging and topside personnel conductingprep work for Divers, this repair evolutionencompassed over 340 hours of safediver bottom time without accident or injuryto personnel. SWRMC and PSNSDivers completed the task of changing two32-ton propellers on schedule. Thesecomplex Underwater Ships Husbandryrepair efforts saved the Navy andCOMNAVAIRPAC over 10 Million dollars(conservatively) in limited Fleetrepair funds and returned this nationalasset to full duty.

August 1, 2007, began as just anothernormal summer day in Minneapolis- bridge construction, bumper to-bumpertraffic - when the 40-year-old, I-35Wbridge collapsed, cutting the city in halfand dropping the vehicles crossing it 65feet into the Mississippi River.The bridge collapse caught the cityand the nation by surprise, triggering rapidrescue response from the military as wellas bridge inspections across the country.After the bridge collapsed, commutersdriving home from work becamerescue workers, and city police and emergencypersonnel faced the daunting taskof trying to save people in cars that weresinking into the river. By the end of thenight, five people lost their lives and 79were injured. Eight were still missing.Local officials began working torecover the missing while looking forwhy this disaster occurred.After a couple days of searching,officials determined the local SCUBADivers were not equipped to dive inthe tight areas around the debris. TheHennepin County Sheriff in charge ofthe recovery operation requested theassistance of Navy Divers.Navy Divers prepare to enter the water of the Mississippi River.“There came a point where we maxedout our capabilities and had to ask foradditional assistance,” said HennepinCounty Sheriff Richard Stanek. “That’swhen we asked for the Navy Divingand salvage team. They are performingbeyond our expectations of what theyThe site of the I-35 bridge collapse over the Mississippi River with a diver line visible justunder the surface.could do operationally in terms of debrisremoval, the equipment they broughton site and the speed in which they deployed.”Members of Mobile Diving andSalvage Unit (MDSU) 2and Underwater ConstructionTeam (UCT) 1, bothpart of Navy ExpeditionaryCombat Command,Naval Amphibious BaseLittle Creek, Virginia Beach,Va., arrived August 6, andby 2 a.m., August 7, thefirst Navy Divers enteredthe water to survey the areaaround the wreckage.“We’re taking our time totry to be as safe as possible;it’s really dangerous downthere,” said Navy Diver 2nd Class SeanMcCann, MDSU TWO. “There were alot of hazards in the water; rebar,cement, automobiles, and sharp metal.It’s a tough job, but at the end of theday, I’m really glad to be here helping.”For the next week, the Divers workedin two teams, each standing 12-hour shifts.Their biggest obstacle was visibility. Themurky water of the Mississippi was sothick they could see only a foot in someareas and had to feel their way throughthe wreckage.“Underwater there was zero-to-onefoot of visibility; you had to find yourway around by touching,” said ChiefHospital Corpsman (DSW/SW) DeanDelfavero of MDSU TWO. “This is whatwe do for a living, and these are the conditionswe deal with all the time. It’s veryhazardous down there with lots of looseconcrete coming down around you andscraping your helmet. With these obstaclesit’s very dangerous.”MDSU TWO has experience workingin difficult conditions. As experts inexpeditionary combat salvage, MDSUTWO has earned its reputation duringcombat salvage operations to open the AlFaw waterway in Iraq and through uniqueoperations, such as the recovery of TWAFlight 800, the Challenger and ColumbiaSpace Shuttles, Swiss Air Flight 111, re-1 2 A p r i l 2 0 0 8

floating of YFU-83 in Puerto Rico, thedeep salvage of USS Monitor wreckage,and recovery of Haitian ferry victims.MDSU TWO also responded to HurricaneKatrina.“When I first saw this site, I thoughtthis is Hurricane Katrina all over again,”said Navy Diver 2nd Class (DSW/SW)Noah Gottesman, MDSU TWO. “Therewas devastation, cars, metal, and concreteeverywhere.”After a few days into the operation,Divers found some areas more difficult tonavigate than their gear would permit.“The area we searched on Aug. 8included under the bridge platforms andI-beams,” explained Cmdr. Dan Schultz,Commanding Officer of MDSU TWO. “Itwas so restrictive that Divers had to removetheir dive gear to crawl into theseareas, some as narrow as 12 inches wide.”While the Divers were searching theriver, Minnesota’s Secretary of TransportationMary E. Peters visited the site for athird time to meet the Divers and thankthem for responding in the state’s time ofneed.“I think theDOD response hasreally made thecommunity appreciatehow muchthe military ... supportsour nation,not only in a timeof war, but in atime of humanneed and crisis,”said Peters. “DODcame in with Soldiersand Sailors toreally help thiscommunity outimmediately.”Finally, onAug. 9, the Divers found the first victimin the water. During the course of theirsearch in Minneapolis they would recoverall eight of the missing.“This is what we are trained todo,” Delfavero said. “We bring closure tofamilies, recover things that are lost inthe water, provide humanitarian aid, andbe Navy Divers. This is what it’s all about.This is our job.”Even though their task was grim,the Divers felt it was their duty togive closure to the families of themissing.“Helping the people out inMinnesota is a privilege for me,and it’s a privilege for the Navy,”said NDC(DSW/SW) Justin M.Scarbourgh, MDSU TWO. “It’s nota glorious job that we’re doing, butit’s an honorable job. “I am a Divernot a hero, but I do what I can formy country and the community.”Another Diver, Electrician’sMate 1 st Class (SS/DV) John Miller,is not a member of MDSU TWO.He is stationed on fast attack submarineUSS NORFOLK (SSN 714)but he volunteered to work with theteam because of a personal need tohelp his home state.“It was one of those things thatfelt crazy – I must have driven overAutomobile being lifted from the river.that bridge a million times,” Miller said.“So I called around and learnedthat MDSU TWO was coming to Minneapolis.Then I called the XO and told himI wanted to come and help, too.”Miller was not trained in hard hatdiving but after his arrival he helped inevery way he could; such as manning thedive station, charting dive times, tendingto the Divers and their equipment.“Being in the Navy and from Minnesota,I never thought I’d be coming backhere to work,” Miller said. “This is somethingthat has to be done to help bringclosure to the victims’ families.”While the Divers worked in the river,mourners gathered at a nearby bridgeto watch. Some even found ways tocontact the Divers and express theirappreciation. “We had a small containerof baked goods brought down to thesite one morning and there was a noteon it from the mother who made them,”said Lt. Li Ping Sung, diving officer fromUCT ONE. “Her note said, ‘Please lookout for our loved ones, and expressedhow grateful her family was. For me itreally struck home what we were doingand the significance of our mission.”MC2(SW/AW) Elizabeth Merriam isassigned to Fleet Public Affairs Center Atlanticin Norfolk, VA.Navy Divers prepare to enter the water of theMississippi River.A p r i l 2 0 0 8 1 3

ORCA with MK-III.With the release of USN DivingManual Rev 6 planned for thissummer, I want to update you on theORCA program. To support the requirementsof AIG 07-07 (New AirDecompression Procedures), NAVSEA00C procured and certified four ORCAunits. These are held at the EmergencyORCA-II with FADS-III.Ship Salvage Material (ESSM) depot inVirginia. These original ORCA are sentto a command for a specific mission thatrequires the use of in-water oxygendecompression. Upon completion of thespecific job they are returned to ESSM.It was never intended that these units beissued permanently to Fleet units.A new design of ORCA, the ORCA-II has recently completed the first Fleetcertification at Mobile Diving SalvageUnit ONE (MDSU ONE). 00C has asufficient number of ORCA-II for theinitial delivery to both MDSUs and theUnderwater Construction Teams. Theseare historically the commands performingthe majority of the decompressiondiving. 00C will procure additionalORCA-II based upon Fleet demand.The combined dive teams fromMSDU ONE and Pearl Harbor NavalShipyard (PHNSY) all preferred theORCA-II over the ORCA for ease of setupand use. In the near future SUPDIVEwill release an AIG 239 detailing the Fleetimplementation plan for both the DiveManual Rev 6 and ORCA-II delivery tothe Fleet.I want to thank the Divers fromMDSU ONE for their work in makingthis certification go off without a hitch.

THE COMMANDANT OF THE UNITED STATES COAST GUARDWASHINGTON 2059311 June 2007The Commandant of the Coast Guard takes pleasure in presenting the COAST GUARDMERITORIOUS UNIT COMMENDATION to:MOBILE DIVING AND SALVAGE UNIT ONEPEARL HARBOR, HAWAIIfor service as set forth in the followingCITATION:For meritorious service from 19-26 January 2007 while responding to the damaged Chinese MotorVessel (MIV) TONG CHENG. On 17 January, TONG CHENG requested a refuge in Hawaii due to afracture in their number two cargo hold. The vessel was taking on water, leaking diesel oil, and indanger of sinking. The U. S. Coast Guard, Customs and Border Protection, and the State of Hawaii’sDepartment of Health held the vessel offshore for fear of the vessel sinking and polluting Hawaii’spristine shores. Demonstrating exceptional adaptability, ingenuity, and perseverance, U. S. Navy MobileDiving and Salvage Unit (MDSU) ONE executed superb diving and salvage operations on theTONG CHENG which ultimately prevented the ship from sinking, averted the catastrophic release of140,000 gallons of fuel, and contributed to the strengthening of goodwill between the U. S. and thePeople’s Republic of China. While operating 80 nautical miles (NM) off the southern coast of Oahu,MDSU ONE performed a critical underwater hull survey that confirmed the vessel’s damage. Despitethe challenging sea conditions, MDSU ONE expertly completed underwater repairs that temporarilyrestored the vessel’s water tight integrity. In addition, the team’s follow-on detailed assessments providedimportant decision-making information to the unified command that ultimately allowed the shipto anchor 1 NM off Honolulu Harbor. With no other means available to dewater the vessel at anchorage,MDSU ONE swiftly conducted diving operations to install three underwater flanges outside the floodedcargo hold which were used to safely remove 210,000 gallons of fuel contaminated water and raise thevessel’s draft. This allowed TONG CHENG to safely enter Barbers Point Harbor to make permanentrepairs. The pride, professionalism, and devotion to duty displayed by Mobile Diving and Salvage UnitONE personnel are in keeping with the highest traditions of the United States Navy and the UnitedStates Coast Guard.”The Operational Distinguishing Device is authorized.For the Commandant,For the Commandant,Rear Admiral, U.

Deep Submergence Unit’s (DSU)mission statement is a bold taskingfor the next generation of Navy Diversin light of changes in manning andequipment. We are in the process ofcertifying the Navy’s newest submarinerescue asset, the Pressurized RescueModule (PRM). The PRM is a tethered,manned Remote Operated Vehicle (ROV)that can hold two Internal Attendants(IAs) and 16 rescuees from a downedsubmarine in up to 2000 fsw. In the future,NAVSEA PMS 394 has plans for aTransfer Under Pressure (TUP) system thatwill consist of two 32-man chambers anda deck transfer lock along with flexiblemanways to allow saturated rescuees to beevacuated and decompressed from asubmarine. The IAs need to be Diversbecause of the disabled submarine’spressure. Meanwhile the PRM descends tothe submarine’s watery vault to retrieveanother load from Davy Jones’ Locker.The transport requires at least two C-5 typeaircraft to get it to the scene of the incidentillustrating its enormity. The entire PRMand TUP system as well as other parts areencompassed in the Submarine RescueDiving and Recompression System(SRDRS). This entire system will take fiveC-5’s to transport it to a rescue site.In addition to the PRM, we host theonly two remaining Submarine RescueChambers (SRC) in active service for theUSN. Navy Divers and submariners operateand maintain these systems. Someof the old salts remember these from theold Submarine Rescue Ships (ASRs). TheSRC is capable of rescues to a depth of850 fsw with a capacity of six rescuees.A large set of air racks and a valve consolemake this reminiscent of hyperbaricchamber operations, but on a larger scale.This system offers a lightweight andhighly portable alternative to othersystems because it can fit on a single plane.The last remaining active Deep SubmergenceRescue Vehicle (DSRV), called“Mystic”, also resides at DSU and is expectedto be relieved by the PRM this year.Divers are required to support the launchand recovery in purportedly the mostperilous SCUBA diving evolution thatthe US Navy performs. Divers have alsobeen used for emergency egress of DSRVpersonnel when a problem occurred.DSU also hosts all four of the world’sonly 2000 fsw One Atmosphere DivingSuits (ADS). This ADS is portrayed in thepicture on page 19. Each piece of the suitis made of a solid block of aluminum thatis milled out to fit a Diver inside. The multiplepieces allow a Diver to move withmuch more dexterity than would normallybe afforded by a ROV. The ADS suit alsoallows topside to have “live eyes” on theproject with a person in the suit. The Diverenters the suit and is sealed inside at oneatmosphere. Oxygen is trickled in formetabolic make-up and a large scrubberand fan remove the natural by product ofoxygen metabolism maintaining the pressureat one atmosphere inside the suit. Lifesupport is monitored and the dive is supervisedfrom the surface. The “pilot” fliesthe suit up, down, left and right with theuse of foot controls while the hands remainfree to work on projects through theuse of manipulators. Because of the innovativedesign, the suit affords no-decompressiondiving to 2000 fsw for up to sixhours. This asset is used for intervention,defined as surveying the disabled sub,clearing the escape hatch and connectinga downhaul cable for the SRC.If the aforementioned “toys” were notenough to entice you, we also haveMK 21 and MK 20 UBA’s as well as asurface-supplied MK 3 Light WeightDiving System (LWDS) system with the600-foot umbilicals and the extra air rackto attain depths of up to 190 fsw. Thisasset is used for intervention in the moreshallow depths and for training and proficiencyof the Navy Divers who come tothe command. As mentioned before, wemaintain a robust SCUBA locker for emergencyprocedures as well as Mystic launchand recovery and to maintain diver proficiency.What command with Navy Diverswould be complete without a recompressionchamber? We have a TransportableRecompression Chamber System (TRCS)for treatment, practice, and to serve asa mobile transfer lock for the new TUPsystem. Lifting and rigging evolutions area plenty and we regularly lay legs ofour lightweight mooring systems. Thesidescan sonar system and small ROVsare also used in our operations.DSU is steeped in tradition. Ourbuilding is named after MMC WilliamBadders who was one of the CongressionalMedal of Honor recipients fromthe rescue of USS SQUALUS. Our oneatmosphere suits are named after the fourNavy Diver Medal of Honor recipients andthe PRM is aptly named after the salvageship USS FALCON from which the rescuewas mounted. As you can imagine, weare very busy with training and maintainingproficiency. There is no shortage ofopportunities to get underwater at DSU.Divers can earn the Deep SubmergenceInsignia for their efforts at the command.If you are up for a challenge and are lookingfor a command that has significantdiving with multiple opportunities to excel,DSU may be for you. You will alsohave the opportunity to learn and use thenewest diving equipment the world hasto offer. At DSU, beyond all other commands,pride and tradition run VERYdeep!LDCR Joseph Dituri is the Deep DivingDetachment OIC at DSU San Diego CA.1 8 A p r i l 2 0 0 8

Maneuvered via foot controls,the pilot “flies” hands free in order to performthe necessary operations under water.There are four suits in the world ratedto that extreme depth, two of them are ondeck of this ship now. Compared to an oldbrass diving helmet, or even the far superiormodern fiberglass helmets with theability to attach cameras, lights, weldinglenses and the benefit of using an oral na-sal mask for air, the hard suit gives theNavy an ability unimagined previously.One of the interesting visual elementsis that the background sky/horizonis super blurry.

Diver surveying JULIETT 484.They say that April showers bringMay flowers, however, on April 17th2007 the showers that relentlesslypounded the state of Rhode Islandproved to be too much for Russiansubmarine K-77, more commonlyknown as JULIETT 484. In a mere30 hours, the former cruise missilesubmarine went from museum attractionto a storm casualty.JULIETT 484 belongs to the SaratogaMuseum Foundation. Modifiedin Finland, it was transformed into amuseum to help generate funds to securethe procurement of the USSSARATOGA and establish an “Air, Land& Sea Heritage and Technology Park inRhode Island…with the SARATOGAbeing the center piece.” Modificationsincluded the cutting of the forwardand aft weapon loading hatches toaccommodate tourist access into thesubmarine. Though the accesses wereconsidered to be weather-proof, theywere not water tight. A number of factorscontributed by the storm, such as strongwinds, heavy rain, and an abnormallyhigh tide, resulting in a torturous thirtyhoursinking of the precious piece ofhistory.The sinking progressed slowly enoughthat it was not initially thought possible.It was documented by a series of photographswhich can be viewed at the websitehttp://www.oakhamgraphics.com/K-77/sinking.html. In fact, it was originallyassessed to be onlyswamped. But as thesubmarine tilted awayfrom the pier it wasthought that it could bestabilized by securing itto the pier with heavierlines. In the early morningof 18 April, the dutyofficer of the museumreported hearing a loud“shotgun” blast as linesparted and the submarinerolled over and slippeddeeper into the ProvidenceRiver. As themorning sun began tobeat the darkness away,it revealed what was left to be seen ofJULIETT 484... just a few remainingJULIETT 484 after storm.antennae and periscopes, peeking abovethe waterline.The President of the SaratogaMuseum Foundation, Mr. Frank Lennon,began the daunting task of figuring outhow to rescue the famous JULIETT 484which had shared a leading role inthe movie “K-19: The Widow Maker”with actor Harrison Ford. Contractorswere hired using both Divers and ROVsto survey the sunken submarine andthe river bottom on which it lies. Inthe meantime, NAVSEA 00C informedCommanding Officer MDSU TWO of thescenario and CDR Shultz elected to “jumpon the opportunity to conduct some uniquetraining.” So, in April MDSU TWO MDSCompany TWO conducted a LeadershipReconnaissance of the submarine andsite in preparation for the possibility offollow-on tasking through the Officeof the Secretary of Defence (OSD)Innovative Readiness Training (IRT)program. IRT, a program established in1993 by the Clinton administration, isdesigned to help build and improve civilmilitaryreadiness through the executionof joint military training ventures whichsupport civil community efforts. Once IRTassistance is established it allows themilitary to help in civil matters based onthe amount of training opportunities andjoint inter-operability that can be utilized2 0 A p r i l 2 0 0 8

y the individual commands who canaccomplish certain tasking – a by-productof the training is the end product for thecustomer.In August of 2007, MDSU TWO andArmy Divers combined forces to conducttheir own joint initial assessment of theJULIETT 484 and to further stabilize herhull. Results of the survey indicated shewas firmly planted in the mud at a 48degree angle, listing to her port side.Decisions were made to further stabilizeJULIETT 484 for additional safety priorto commencing future salvage operationswhich would prevent additional rolling tothe port side. This was accomplished byburying 7,000 lb. Stato anchors into theeast bank and attaching wire rope from theanchors to strong points along the unit.MDS Companies TWO-FIVE andTWO-SIX (formerly Dets Six and Eight)of MDSU TWO conducted several divesaround the exterior and eventually intothe sunken submarine to assess thecondition of the submarine. The informationacquired from those dive setswill be the basis of the salvage planwhich will ultimately be used whenfloating the submarine. Traditionalresources that would normally be readilyavailable for this undertaking have beendifficult to gather. Technical drawings ordocking plans have been impossible toobtain from the Soviet Union since theyare still deemed to be confidential by theRussian government. Information thathas proven to be helpful has been preproductionmovie pictures, videos anddrawings that were developed for themovie “K-19” when the submarine wasslightly modified to accommodatefilming.Currently plans are underway toreturn during the summer of 2008 andcontinue the salvage of the JULIETT 484.Raising sunken vessels traditionally hasbeen the hallmark of Navy Divers butas years have gone by, opportunities topractice the fine “art” of salvage of thismagnitude have become a rare occurrence.It is one thing to retrieve pieces of aircraftoff the bottom of the ocean but to raisean entire vessel like a submarine is another– it is going to be a great summer!!Submitted by Naval Expeditionary CombatCommand, Public Affairs Office, Norfolk, VA.“Bottom time is a premium” has beena tenet of U.S. Navy Diving since itsinception. From July to October 2007,HM1 Daniel Stevens and HM1 ShannonJohnson from Mobile Diving and SalvageUnit TWO Companies TWO-ONE andTWO-FIVE worked with HMC MikeLewis from NEDU to bring Navy Divinginto the new millennium. The TopsideDecompression Monitor system (TDM)was tested providing Divers with realtimedecompression obligations in thewaters of Sardinia, Italy. The data gatheredfrom the hundreds of dives was acritical element in bringing the TDM tofull integration into Navy Diving. TheTDM consists of a pressure-sensitivetransmitter attached to a cable, which ismarried into a standard surface-supplieddiving umbilical. The sensor and cablefeeds information back to a laptop computerproviding the diving supervisorreal-time information as to the Diversdecompression obligation.MDSU TWO Diver operates ORCA.Current decompression tables use themaximum depth and time to calculate adecompression table and schedule. Thishas been to the exclusion of how long theDiver was actually at that deepest depth.The sea story of a Diver working on theunderside of a ship who drops a toolillustrates this perfectly. The Diver initiallyon a “No D” dive at relatively shallowdepth drops his tool to the bottomwhich is at 62 ft. he would now owedecompression on a 70 ft. table for theentire bottom time. Logic naturally saysthat with an excursion of one minute tothe deeper depth the Diver would not ongasenough nitrogen to justify the deeperMDSU TWO Dive team.table and schedule. Until now supervisorsBy: ????had no other choice but to go with thedeepest table and schedule.Giving Divers even more flexibilitywith how to contend with their decompressiontime are the VVal-18 tables. TheDivers of MDSU TWO performed over400 dives with an average depth of 100fsw on the new tables without a single incident.These tables are an integration ofstandard air tables, in-water on oxygentables and SURDO 2tables into one singleoperational table. The integration is possibleonly because of the Oxygen RegulatorConsole Assembly (ORCA), andnow the lighter and more capable ORCA-II, which provides the capability ofswitching to in-water on O 2by simplyturning a few valves. This is especiallyuseful for contaminated water divingwhere Divers can now drastically cut theirin-water decompression time then comeup and over for decontamination. Thisgives diving supervisors flexibility fromhaving to obligate to one type of decompressionand to make a seamless transitionbetween the three types of decompression.In the near future Navy Divers willbe able to integrate both the TDM andVVal-18 tables into a single system. TheVVal tables will provide greater safety andflexibility while diving supervisors monitortheir Divers in real time on the TDM.Together these two systems will safelymaximize the bottom time while minimizingdecompression to only what is necessary,because as we all know “bottom timeis a premium.”Ross Garcia is Command Master Chief ofMDSU TWO.A p r i l 2 0 0 8 2 1

The crystal blue water and extensivebeaches of Fort Lauderdale, FL seemlike an unlikely spot for old tires. Overthe years tires from a failed artificial reefhave been washing up on Florida beaches.But thanks to the cooperative efforts ofCoastal America, the U.S. Navy MobileDiving and Salvage Unit 2 (MDSUTWO), and other federal and statepartners, the Osborne Reef is finallyevolving from an unsuccessful artificialreef venture to a training opportunity formilitary salvage teams and a recycled fuelsource for Georgia and Florida.The Osborne Reef, or as it may bebetter known, the Tire Reef, 1.3 miles offthe coast of Fort Lauderdale, wasconceived in 1972 in an effort to resolvean overabundance of old tires that waschoking landfills and creating potentialhealth risks in southern Florida. A groupof local interests, including fisherman,boaters, Divers and politicians receivedthe blessing of the Army Corps of Engineersto gather nearly two million old tires,lash them together and anchor them to theocean floor as an artificial reef.The concept of artificial reefs hasbeen around nearly as long as man hasgone to sea. Artificial reefs have beencreated by ships, army tanks, oil rigsand washing machines. What mostintentionally placed materials havein common is a hard andvaried surface that can provideshelter for fish and asubstrate to which corals,sponges, algae and molluskscan attach.Tires as reefs wereappealing for two reasons.First, during the 1960s and1970s used tires were accumulatingin landfills afterrestrictions on other disposalmethods were imposed.Second, by grouping largenumbers of tires together, the openingsprovide shelter for fish and other species.But tires have a certain amount ofbuoyancy, causing them to move andeventually break loose of their restraints.And their slick surfaces appear to bemore attractive to a limited range of algaethan coral and other more beneficial reeforganisms.As hurricanes moved through eachhurricane season, and other storms andcurrents pulled at the Osborne Reef tires,their nylon and steel lashings eventuallygave way. Within three years of theirplacement, tires had been moved byregional storms. Eventually, the tiresspread over roughly 34 acres, beganwashing up on beaches and, morecritically, damaging nearby natural reefs.As the tire reef’s failure becameapparent, scientists and conservationistspondered how to get the Osborne Reeftires out of the ocean. In the simplestterms, the solution comes down to threeissues: Who has the legal authority tomanage the project? Who has the technicalexpertise to perform the task? Whowill pay for it?Projects on this scale easily run intothe millions of dollars and no one singleagency or government could finance theoperation.Members of the Osborne Reef salvage training mission.Navy Diver retrieves tires.In 2001, Robin Sherman of NOVASoutheastern University initiated a smallscaletire retrieval pilot program after receivinga $30,000 grant from the NationalOceanic and Atmospheric Administration(NOAA). Approximately 1,600 tires wereretrieved at a cost of $17 per tire. Thatcost made a full project cost-prohibitive.Two federal programs that have cooperatedon other projects seemed tooffer a possible answer. The CoastalAmerica program is a federal program thatcoordinates resources from variousfederal agencies to help address needsin coastal communities. The Departmentof Defense Innovative Readiness Training(IRT) provides the military with a wayto gain hands-on training while providingbenefits to communities.In 2006, Coastal America projectcoordinator William Nuckols contactedthe Broward County Department ofEnvironmental Protection (DEP). He suggestedthat Coastal America coordinatewith Broward County DEP on a majorproject to remove the tires and in August2006 the NOAA Marine Debris Programfunded a reconnaissance project for developinga tire removal and disposal strategy.The project removed only 30 tires,but it enabled the participants to determineprocessing suitability, handling, staging,transportation methods and end uses for2 4 A p r i l 2 0 0 8

the reef tires. It also made clear that aproject of this magnitude can’t just bedone as a volunteer effort and that removinga few tires wouldn’t alleviate the problem.Nuckols suggested that this type ofproject might fall within IRT guidelinesand proposed contacting the militaryabout the project as a training exercise.He recognized that Navy Divers fromMDSU TWO, located at the NavalAmphibious Base Little Creek in Norfolk,VA, had the qualifications and experienceto handle a job of this size and scope.He contacted the MDSU TWO OperationsOfficer to determine whether the tirereclamation project would have valuefrom a real-world training mission pointof view.The tire reef project offered multipletraining components, including salvagediving at depths of 60 feet or more.More importantly, it offered experiencein logistics and communication coordination(i.e., interoperability) with multiplefederal, state and county agencies involvingthe Navy, Army, Coast Guard, theState of Florida and Broward County.Each has its own policies, proceduresand terminology, all of which had tobe coordinated for safety and projectsuccess. The ability to develop a coordinatedapproach quickly is critical inemergency situations, such as naturaldisasters.“By aligningmilitary salvagetraining exerciseswith this realworld problem weaccomplish a coralprotection projectthat governmentnatural resourceagencies wouldnot have beenable to accomplishon their own,”Nuckols said.Having determined suitability, securedfunding for travel and completedrequired applications, CWO4 DanMikulski lead a team of six MDSU TWODivers to Fort Lauderdale. Mikulski,along with the other Divers from hisunit, dove the reef and performed a sitesurvey.A MDSU TWO Diver receives instructions anda safety check before submerging to the reef.“Once we completed the site survey,we came up with a plan to complete themission and determine the number of tireswe could bring up per day,” Mikulski said.Fort Lauderdale residents have seentires wash up on their shores for almost30 years – not realizing that they werecoming from a reef a little more than aThe crew observes a bundle of tires emerging from the reef.mile off shore. Once word spread thata cleanup effort was underway, communityvolunteers and supporters came tohelp.“In Broward County where thereef is located, most people includingthe dive shops, didn’tknow it existed eventhough it covers almost34 acres,”Nuckols stated.A photographerand local reporterscovered the sitesurvey, resulting inwidespread reportingof the clean-up beginningwith a MiamiHerald article inAugust 2006 andcontinuing through September 2007,every major news outlet in the country hadpicked up on the story.After the State of Florida committedtwo million dollars to transport and recyclethe tires, MDSU TWO support was approvedand the Army and Coast Guardwere onboard. Beginning 1 July 2007,MDSU TWO led a salvage mission toremove nearly 1,000 tires a day. Supportingthe effort were diving and watercraftassets from the Army’s 7th TransportationGroup, two Coast Guard detachmentsfrom Homestead, Florida, the BrowardCounty DEP and the State of Florida.Coastal America provided guidancethrough the initial stageof the project.During the retrievalprocess, Divers workedin approximately 60-70feet of water and haveto place 50-70 tires in4,000 pound cargo liftnets under water. Then,using inflatable airbags,floated the tires tothe surface where acrane mounted on anArmy Landing CraftUnit lifted them out ofthe water onto two 48-foot trailers.The Navy Dive team leader Mikulskipointed out that the rigorous work Diversare performing limits the amount of timethey can stay under water. The heat is alsoa factor, as summer ocean water temperaturesin Florida reaches 80 degrees.This tedious cleanup of between500,000 and one million tires from a 34acre area, equivalent to about 31 footballfields, is expected to take nearly sevenyears. Each year, work is slated to beginon 15 May and continue for 90 days tominimize conflicts with the end ofFlorida’s tourist season and avoidworking in rough seas at the beginningof hurricane season. So far, the cooperationamong the groups has resulted in aseamless project that can continue asplanned at a cost of $2/tire, a significantsavings from the previous $17/tire estimate.An important part of the operation isnot only getting the tires to the surfacebut then being able to dispose of them.The tires are transported to Port Ever-(“REEF” continued on p. 26)A p r i l 2 0 0 8 2 5

(“REEF” continued from p. 25)Iwant to take a moment to touch on atopic that will affect all of us very soon– the release of the U.S. Navy DivingManual Rev 6, which will contain theNew Air Decompression Procedures. Iroutinely receive phone call asking whenRev 6 will be out. I understand why youare calling – it is later than advertised, butfor good reason. Here’s why.In May 2007, Diving Advisory AIG07-07 authorized the use of VVal-18M,New Air Decompression Procedures. Thisis new Chapter 9 in the Diving Manual.Additionally, it directed these tables beused for any dives with greater than 15minutes of decompression time. Withinmonths of releasing AIG 07-07 the salvageeffort in La Maddalena was beginningto take shape. (See article on page8.) This was the ideal opportunity to givethe new Air Diving Chapter 9 a Fleetevaluation. It was decided that Rev 6would benefit from the feedback from thisoperation. In order to capture the lessonslearned, a revision to the procedures inAIG 07-07 was planned for.All necessary equipment, OxygenRegulator Console Assemblies (ORCA)was delivered to USS EMORY S. LAND(AS-39) and MDSU TWO Divers. Trainingwas conducted and system certificationwas granted to modify their PSOBsfor VVal-18M. Working with the MasterDivers running the operations in Italy, 00Ckept in constant communication, sometimes answering questions but more oftentaking their suggestions for inclusioninto Rev 6. This did slow down deliveryof Rev 6, but I believe that this resulted ina much better, Diver-tested, Chapter 9. Iwant to thank all of the Divers involvedin the La Maddalena effort for theirpatience and hard work in helping “fix”Chapter 9. Especially, MDV Sam Mata,MDV Mat Rotan, MDV Arne Phillips, andMDV Billy Gillbert. They made all of thiscome together.This operation provided anotherpotentially more valuable opportunity, areal world application of VVal-18M. Iknow there are people that don’t thinkwe should change our 50 year old decompressiontables. Some believe that thesetables have worked fine for years. To youI say, never mind the experimental DATA,never mind what thestatistics say, comparethe results ofreal world operationsand it’s obvious wehave made the rightdecision.The dives performedon the LaMaddalena operationare very similar to those during the salvageof TWA flight 800. Using theSURDO 2tables, as written in US DivingManual, Rev 5 we experienced a high rateof DCS, most were serious Type-2,chokes, paralysis, ect. The operation continuedby modifying the Rev 5 tables, addingup to three “jumps” into theschedule until an acceptable margin ofsafety was reached. The New Air Decompressionprocedures (Rev 6) tables wereused as written with no cases of DCS.See the table for a comparison of divesperformed and incidents of DCS. Thechart lists all dives between 110 fsw and130 fsw, for both TWA 800 and the LaMaddalena site jobs.Tell the youngest Diver in your lockeryou used to dive MK-12 (or Jack Browneif you’re old enough) then show themone, and they’ll say “What were youthinking?” In five years if you tell thenew Diver you used to decompress withoutoxygen they will say “What were youthinking?”MDV Pratschner is Command Master Diverat NAVSEA 00C.2 6 A p r i l 2 0 0 8This tiny fish represents one of the few specimensof marine life one can find along the reef.glades and ultimately shipped to Georgia,typically for processing into either an energyresource for cement kilns or municipalsolid waste facilities. The tires can alsobe chipped and used as light weight fillinaggregate for highways or turned intotire-derived fuel, displacing fossil fuelsproviding energy for power plants andpaper mills.The Miami Herald actually prints itsnewspaper on recycled paper from one ofthe mills to which cut up Osborne Reeftires have been shipped for use as TDF.“The weirdest connection is that I’mreading a story in Miami, a story producedby the Herald, written on recycled paperproduced by a plant in Georgia where wesend the tires,” Nuckols notes. “It showshow things can come around full circle.”For decades, tire reefs have been creatednear coastal states and around theworld. And though well-intentioned,people now realize the negative effectsthose tires can have on the marine environment.Fortunately, technology nowallows old tires to be recycled, providingneeded energy sources, reducing wastedisposal issues, and minimizing thepotential for those tires to harm the ocean.With the cooperative efforts of CoastalAmerica, the Navy, and other federal andstate partners, the Osborne Reef is finallyevolving from an unsuccessful artificialreef venture to a training opportunity formilitary salvage teams and a recycled fuelsource for Georgia and Florida.CWO2 Motley is currently assigned toMDSU TWO as OIC Company TWO SIX.DISCLAIMER"Reprinted with permission from Currents – theNavy’s environmental magazine.

From SUPDIVE... CAPT John GrayFellow Divers:I am writing you from PortsmouthEngland where we are actively workingwith the United Kingdom, Canada, Australiaand New Zealand to improve our integration.In addition, we are discoveringwhat our allies do best and learning fromit. More on that in a future edition of Faceplate.I would like to take on two issuesfor which I hope you have a strong opinionone way or another. Every time I bringthem up a passionate response followssometimes to the point where I feel physicallythreatened but that’s my problem.As you know, the current DiveManual, and even Revision Six, requiresa chamber on-site whenever conductingAir decompression dives to a depth ofgreater than 130 feet. My question tothe fleet is why? Because, honestly,SUPDIVE hasn’t a clue as to the reasoningbehind that number. Why not 129feet? Why not 131? The British have asimilar requirement at 42 meters (roughly136 feet). OSHA requirements are set at100 feet. Some folks, maybe even me,might say that this rule needs to bechanged and let the smart folks in the fleetapply a little ORM vice some staff guy inWashington (me) trying to pretend he isan operator. Stick with me as we walkthrough the history and some argumentson both sides.Despite a complete search of all thetons of paper work that lines the halls of00C and interviews with folks that haveserved here in excess of 25 years, we cannot find documentation as to why 130feet was chosen. Our best guess is that italigned nicely with the various SCUBArequirements that are implemented at 130feet. In short, we wanted to draw the linein the sand somewhere and 130 feetseemed like a reasonable depth to do that.There are multiple arguments that can bemade on both sides of this issue. I’ll outlinethe top three.Far and away the number one reasonfor having a chamber requirement at 130feet is omitted decompression. Specifically,as we go deeper the odds of accidentallygetting into a decompressionprofile (for whatever reason: entrapment,poorly executed dive) increases. We allagree that it’s better to have a chamberaround if you are dealing with omitteddecompression.A case can also be made that if nospecific requirement is articulated, in aworld of limited assets, that we put bothbillets and equipment (chambers) injeopardy. Likewise, I think we all canagree that this could be an issue but arewe defining the requirement correctly?Finally, many have pointed outthat if no “Top Cover” is given in the divemanual, that many Master Divers andOICs will be prevented from bringing achamber to an operation by their CommandingOfficer. This concern is based onthe assumption that the CommandingOfficer, who may not be a Diver, will notunderstand the safety issues at hand andopt to save the cost associated with transportand so forth.The best argument against the 130foot rule is that has no scientific basis. Ispend a lot of time with a lot of smartpeople and I get to look at dive datathat many in our community don’t haveaccess too. Despite our experience withTWA 800, I can tell you that based on38,000 dives or so that there is no significantincrease in the likelihood of DCSbetween say a 120 foot dive and a 140 footdive. We bend most folks on no decompressiondives. There are a couple of reasonsfor that. First, most of our dives areno decompression. Second, there is nothingmagical about a 60/60. Two percentrisk is built into the equation. Dive 60 feetfor 59 minutes enough times and you willget bent. So, in summary, no decompressionscientist can look you in the eye andsay that there is anything special about 130feet.We have been inconsistent formany years. The current dive manual doesnot require a chamber for MK 16 unlessyou are diving greater than 200 feet. Thenew dive manual will suggest 130 feet but,in the end, leaves the decision up to theoperational commander.Managing the Risk.AGE. Outside of the School House,Ascent Training, and NEDU, AGE simplydoesn’t happen much. It is a very veryrare occasion. When I went to dive schoolthey taught me that you could embolizein four feet of water. Again, nothing specialabout 130 feet.As far as DCS is concerned, you areat higher risk for DCS on a 100 foot divewith a long bottom time then say a 140foot dive for 20 minutes. Again, nothingspecial about 130 feet.So Fleet, in the end, we are left with afew options.Maintain the Status Quo – If it isn’tbroke don’t fix it. I personally have a hardtime with that one but it’s an option.Require chambers for shallowerdives, perhaps 100 feet, perhaps for anydive. A good argument can certainly bemade for this course of action. Aligningwith OSHA would be looked upon by mostas a good thing. If no risk is acceptablethan a chamber on-site all of the time isthe way to go.The final option would be to linkthe requirement to actual risk of DCS.NAVSEA can develop a simple chart ofsay five percent DCS risk (in practice,most DCS models estimate high, for exampleour tables are primarily based ontwo percent DCS and we actually observeabout POINT two percent). Dives abovethe five percent risk would require a chamber,those below; it’s up to the command.This is the option I am currently in favorof. I do my best to define the risk, the commandsactually making the dives decideweather to take the risk or not.(“SUPDIVE” continued on p. 27)A p r i l 2 0 0 8 2 7

The 6 th Annual DC Diver Charity GolfClassic was successful in raisingover $4000 for The Navy Marine CorpsRelief Society. The tournament wasagain held at the Andrews Air ForceBase West Course on Friday, October 5 th2007.
