Final Report, SONS Deepwater Horizon Oil Spill, Gulf of Mexico, 27 April — 24 September 2010 Lesson: If the currents are more than 1 knot, boom should not be deployed across the currents. Recommendation: If boom must be laid, boom should be anchored in a cascade or deflection mode. Lesson: Mud and sand slowed the boom assembly progress. Recommendation: A flat hard surface working area is preferred during assembly of boom. Lesson: Boom deployment and/or recovery were difficult when the boom roller was not in line with boom. Recommendation: Add wings to the boom roller to assist bringing the boom in line when it is out of line. Also keep the connector plates in place and the chain guided on the roller. Lesson: Crown Buoys were damaged in heavy currents. Recommendation: Use large mooring buoys versus the Crown Buoys in heavy currents. Also connect the boom to the mooring buoy with snap hooks in the heavy current. Lesson: Few crew members had experience operating the Class XI Skimmer System. Recommendation: Class XI Skimmer System training needs to be added to the annual training commitment list. Lesson: The Shop Van inventory needs to have a metric socket/wrench set 1/4″ drive standard socket set and a Jabsco transfer pump with hoses. Recommendation: Add metric socket (with 1/4″ drive) and wrench set as well as a Jabsco transfer pump with associated hoses. Lesson: Shop Van -6 Aeroquip QD’s male and female sets (qty 2) need to be added to inventory. Also another set of -16 male and female QD’s to inventory. Recommendation: Add -6 Aeroquip QD’s male and female sets to inventory. Add -16 male and female QD’s to inventory. Lesson: The Class XI 8-ton crane toolbox needs to have all associated wrenches, ratchets, and socket sets for its bolts. Also add a supply of longer bolts. All bolts should have lock washers and Nylock nuts. Recommendation: Add associated wrenches, ratchets, sockets, bolts, lock washers, and Nylock nuts to inventory. 110

Final Report, SONS Deepwater Horizon Oil Spill, Gulf of Mexico, 27 April — 24 September 2010 Lesson: The pushpins for the boom connector plates were not holding; one pushpin fell out completely and was lost. We used 5/16″-18 x 2 1/2″ long stainless steel bolts to replace the pins temporarily. Recommendation: None. Lesson: Need to add a propeller puller to Shop Van inventory for 24′ BHB propeller. Recommendation: Add a propeller puller to Shop Van inventory for 24′ BHB. Lesson: Need to add a rotating tip to the Equipment Decon Van (VA2119A) inventory for the diesel pressure washer. Need to add an 80 degree/2.25 gpm for the Landa pressure washer burner as well as the rest of the pressure washers as needed in the Equipment Decon Van. Recommendation: Add a rotating tip and an 80 degree/2.25 gpm for the Landa pressure washer burner to the Equipment Decon Van. Lesson: When shipping from Port Hueneme, drivers were only given miscellaneous packaged loads (not by system) which caused some problems. Recommendation: Establish a method for personnel to document only what was loaded onto each truck. Lesson: The decontamination stations were inadequate early in the cleanup effort. The crew had some minor problems due to the decontamination crew not fully understanding SUPSALV equipment. Recommendation: Offer hands-on training before allowing non-ESSM personnel to decontaminate equipment. Lesson: The crews had difficulty pulling the Weir Skimmer in and out of the High Speed Current Buster pocket to clean debris out of it. Recommendation: Need portable hydraulic knuckle cranes that can be mounted on containers available for use on any vessel of opportunity. 111
