ME-GI Dual Fuel MAN B&W Engines

A Technical, Operational and Cost-effective Solution for Ships Fuelled by Gas

Abstract

http://test.develop-

two-stroke.engines.and.associated.fuel.

supply.systems..

The.discussion.and.interest.in.lowering.

CO2,.NO,.S.and.particulate.emissions.

have.increased.operators’.and.ship-

owners’.interest.in.investigating.future.

fuel.alternatives..The.ME-GI.engine.of-

fers.the.opportunity.of.utilising.such.an.

alternative.

Market.research.indicates.that,.in.fu-

ture,.gas.applications.may.be.installed.

not.only.on.LNG.carriers,.but.also.on.

LPG,.RoRo,.and.container.vessels,.i.e..

in.principle.all.types.of.vessels.

Therefore,.this.paper.not.only.describes.

gas.fuel.supply.containment.system.

solutions.for.LNG.carriers,.but.also.for.

other.vessel.applications.

The.different.gas.supply.systems.and.

techniques.available.on.the..market.will.

be.discussed.in.this.paper..In.principle,.

there.are.three.different.solutions.for.

combining.the.gas.supply.system.with.

the.MAN.B&W.two-stroke.ME-GI..The.

three.solutions.are.listed.below:.

Furthermore,.we.will.explain.how..

ME-GI.engines.can.be.installed.on.new.

ships.or.retrofitted.in.vessels.already.in.

service,.and.how.to.install.gas.supply.

systems.on.new.or.retrofitted.ME-GI.

engines..IntroductionThe.decision.to.invest.in.dual-fuelled.vessels.will.be.based.primarily.on.the.owners’.expectations.for.the.future.development.in.gas.and.fuel.oil.prices,.safety.regulations.and.emission.control.regulations.MAN.Diesel.has.shown.that.dual.fuel.engines.can.be.more.than.just.eco-nomically.sound.–.dual.fuel.engines.are.also.safe,.reliable.and.environmentally.desirable,http://mercial.application..Beyond.the.whole.question.of.price,.safety,http://pression,.Cryostar.and.Hamworthy..More.specifically.for.LNG.carriers,.the.type.of.gas.supply.system.seems.to.depend.on.the.type.of.application.of.the.LNG.carrier,.e.g..operation.as.carrier.train.between.two.destinations,.or.spot.market.trading.As.of.January.2008,.MAN.Diesel.has.90.two-stroke.MAN.B&W.S70ME-C.engines.on.order.for.45.LNG.carriers.for.the.Qatar.gas.project..All.these.engines.are,.however,.ordered.for.operation.on.liquid.fuels,.i.e..HFO,.DO,.and.GO.as.are.more.than.15,000.MC/ME.type.engines.worldwide.for.different.applica-tions.for.the.marine.market.The.technology.for.a.gas.driven.two-stroke.ME-GI.engine.is.available.–.and.ready.to.install..For.the.past.4-5.years,.MAN.Diesel.has.worked.with.Burckhardt.and.acknowl-edged.how.important.it.is.to.enter.a.strategic.partnership.with.a.manufac-turer.who.also.places.safety,http://ponents.However,.different.applications.can.call.for.different.gas.supply.systems,http://pressor.solu-tions..Therefore,http://ed,http://pressor.and.high-pressure.pumps,http://ed,.depending.on.the.actual.application.requirements.and.the.operator’http://pressor.and.the.high-pressure.pump..The.reliquefaction.process.will.also.be.further.elaborated.Instead.of.reliquefying.the.boil-off.gas.(BOG).and.returning.it.to.the.gas.tanks,http://e.the.BOG.as.fuel.for.pro-pulsion..An.LNG.carrier.can.be.built.or.retrofitted.with.a.dual.fuel.engine..
