HIGH FLEXIBILITY IN SCANA PROPULSION SYSTEMCONFIGURATIONSScana Volda is focusing on optimised propulsion concepts with regard to the different runningconditions and related running cost. Economy in operating cost is highly focused by the shipowner. By tailor designing the propeller system to the vessel there can be great savings. Aconventional propulsion system can be the best solution for one vessel type while a diesel electric,hybrid - or a twin engine solution gives pros to others. Scana Volda Gear and CP-propellersystems can be adapted to most engine makes of medium and high speed type.Scana Volda developes and deliveres propulsion systems to a wide range of ship types and sizes, mainly within the categorydisplacement ships. This contains all kinds of fishing/catching vessels, cargo, tank, passenger, supply, standby, tugs, anchorhandling, seismic, ferries, patrol vessels, and various support vessels.In order to solve the different working conditions the ships are custom designed, but even though some shiptypes willstill have varying running conditions. The varying working conditions requires flexible solutions to execute all tasks inthe most efficient way. The goal is therefore that the ship’s total operating system is optimised to the ship’s actual serviceprofile. With different configurations of engines and gearboxes combined with controllable pitch propeller, it is possible toachieve solutions that satisfy most requirements to flexibility and efficiency.Some examples on propulsion configurations offered by ScanaVolda through a world wide distribution network of salesoffices and -agents:Conventional system based on diesel enginepowerA diesel engine is running the propeller via a reductiongearbox with or without a PTO. A system at a reasonable pricelevel with a simple solution suitable to all ship types witha relatively narrow service profile. Typical ships are cargo,tank, ferries and trawlers. These systems can be driven eitherwith constant or a slightly varying engine rpm dependent onsimultaneous running of an el-generator or if you have fixed orvarying el-frequency on the generator.Diesel electric propulsionThe propeller is driven by one or more electric engines viaa reduction gearbox. The power is delivered from the ship’selectricity supply system. The system gives a very flexible andgood solution to ships with a wide variety range in propulsionpower. Typical ships are longliners, combined trawlers/purseseiners, standby vessels, patrol vessels, icebreakers, seismicvessels, anchor handling vessels and different support vessels.The most effective solution is achieved by a variable rpm atone or more of the electric engines, so that the propeller canhave optimised working conditions in the entire power range.Twin-engine power with father and sonconfigurationThe propeller is driven either by “the father” or “the son”,or by both diesel engines via a twin-in single-out reductiongearbox. PTO’s for power generation are available on one orboth sides. A flexible system at a relatively reasonable pricefor vessels with two-three prevailing working conditions. Theprofit is mainly based on correct combination in use of the twomain engines.

SYSTEM FLEXIBILITYHybrid propulsionThis is a combination of electric drive and diesel drive ofthe propeller. This systems can be used in different ways:a) electric drive at variable rpmb) diesel drive at variable rpmc) both engines simultaneously with fixed rpm or some rpmvariation.It is here vital to operate with variable rpm, at least in thelower power range. This system configuration gives a highefficiency to ship types that most of the time have a variableand very low power requirement and at other times requirea high constant power.Main system: Scana Volda propulsion system is an integrated gear and cp-propeller system, but can also be deliveredas separate units for connection with other gear-and cp-propeller makes. The integrated propulsion system has one servosystem with the servo placed in the gearbox or in the propeller hub. The system can also be delivered with the servo motorin the propeller hub and a radial OD-box in the propeller shaft.PTO/PTI SOLUTIONSScana Volda offers a wide range of different configurations for PTO/PTI solutions for powering generators or pumps fromthe gearbox, or for boost function or “take me home device”. The PTO/PTI can be secondary or primary driven, with up to2 different speed settings, and in a power range from 100 - 3000 kW.Examples of primary driven PTO/PTI’s:Examples of secondary driven PTO/PTI’s:PTO withoutclutch, forgeneratoruse. The PTOwill alwaysrun with theengine.PTO/PTIwithout clutch,for combinedgenerator/elmotor.Extraclutch forrelease of mainengine.PTO/PTIwith clutch,for generatorand/or as PTIwith an el.motor.

SCANA VOLDAWITH GREATSUCCESS IN THETANKER / CARGOSEGMENTScana Volda has been successfulin the tanker and cargo segment in2004. From a company traditionallybeing strong in the offshore andfishing segment now more than50% of the order intake in numberof shipsets has been for tankers andcargo vessels of different size. Oneof the reasons for this is the range oftake-me-home devices from ScanaVolda.Scana Volda’s range of take-mehomesystems varies from the plainversions with a mechanical switchfor engage-/disengagement, to theuse of more complex systems withhydraulic operated multiple discclutches. In adddition the PTI modeclutch is controlled by Scana Volda’sSoftclutch System which results in asmooth engagement.A technical meeting regarding Scana Volda installations for the 2 chemical tankers of Crystal Poolbeing built at the INP Shipyard in Korea.From left: Mr. Sverre Tonheim, Sales Manager Scana Volda,Mr. Mauri Ruohomäki, Surveyor Crystal Pool, Mr.Olav Øverland of Scana Mar-El, Mr. HenningBrautaset Technical Manager at Scana Volda and Øystein Fet, Technical Sales Support Scana Volda.Two speeds PTO/PTI (power take out /power take in) is more often a demandfor tankers in order to be able to run intake me home condition at optimumpropeller efficiency in addition to arequirement for boost effect in normaloperation.One of the recent orders is for theFinnish company Crystal Pool fortwo 10.000 dwt chemical tankers.This solution contains the ACG1080/PS750 2-speed PTO/PTI gearboxwith primary driven PTO for shaftgenerator, and secondary driven PTIfunction for power boost and take mehome with reduced propeller speedfor optimum propeller efficiency. Thedifferent PTO/PTI modes are operatedby hydraulic clutches.High demand forScana Voldaequipment to theoffshore vesselsegmentDuring the last 12 months 27 offshorevessels world wide have ordered-or got installed their ScanaVolda propulsion system.This figure represents a nice shareof the amount of offshore vesselsequipped with conventional cp-propellers.The orders have been a mix of repeatorders and new orders for either newbuildings or refit at shipyards in Norway,Spain, Poland, Iran, Singapore,Brasil and Malaysia.The highest activity from one countryin number of vessels has been toBrasil, with installations for 6 PSV’sfor CBO, 1 for Consub and 1 forDelba.The BrazilianCBO - CompanhiaBrasileira Offshore- has chosen ScanaPropulsion for theirrefit program of 6PSV vessels.Scana Volda is proud to have beenselected by this well reputed companyin Brazil. CBO is one of the importantcontributors to the revival of theBrazilian Industry.CBO has a fleet of 9 vessels including3 PSV’s built at Promar-Aker shipyardwhich has been the starting point forrevival of the Brazilian Industry.CBO has been awarded by Petrobrasfor 3 years in a row as the best offshoreoperators for vessel performance, safetyand environment care.Scana Voldaannounces priceincrease fromJanuary 2005The rapidly increasing demand forsteel world over has already lead to deliveryproblems of raw materials. Thisagain has led to a considerable priceincrease for steel and metal.Scana Volda has done its utmost tocontinue and improve our cost effectiveefforts. Still we now conclude thatwe must increase our prices from January1, 2005. Information will be sentto all our customers in January throughour sales representativesOur sub-suppliers have been forced toincrease their prices at a general basis,and many have introduced a separatematerial amendment which follow theexisting situation in the raw materialmarket.
