  1. Experiences with Gas and Fuel Cells in ship machinery Incentra – rådsmøte, Haugesund 30.08 – 2011 Eidesvik Offshore ASA - KjellM Sandaker

  2. Eidesvik Offshore ASA Shipping company with Head Office at Bømlo, in western Norway. About 600 employees, and MNOK 1054 revenue in 2010. Supply, standby and anchor handling 11 vessels + 3 new Seismic survey and cable laying 8vessels + 1 newbuilding Subsea support 4 vessels + 1 new

  3. SustainableSeaTransportation • What is notsustainablewiththeuseofenergy in todaysSea transport ? • Main Answer: • Useof fossile oil as fuel • Harmfulemissions to theatmosphere • Whatarethenrealistic alternatives to oil ? • Whatcan be possible steps over to realistic alternatives?

  4. Eidesvik Offshore ASA Our experience with gas power in ships Viking Energy From April 2003 Viking Energy From April 2003 Viking Queen From January 2008 Viking Lady From May 2009 2 x TBN Delivery 2012

  5. Engine system arrangement • First generation gas power arrangement • Second generation engines and arrangement Cold Box LNG storage tank Power plant, engines with alternators Viking Energy 94,9 m

  6. Fuel consumptions and emissions with gas power Viking Energy - 2007

  7. Environmentalaccount for producing 1 MWhE, incl. LCA-data Kg Kg SOx-emission NOx-emission MJ Kg Energy consumption CO2-emission

  8. Maintenance LNG and natural gas system proven very reliable. We have more than 12 ship years of operation without technical off-hire due to the gas installations. • Scavenging air canal after 14 000 hours. Maintenance interval is now set to 23 000 hours.

  9. FuelCells –Thirdgeneration maritime gas powertechnology • Better fuelefficiency • Loweremisssions to theatmosphere • Conceptwith Molten CarbonateFuelCells, MCFC, from MTU

  10. Test installation, schematic

  12. Class and authorities • Application for ”approval in principle” wasfiled by Eidesvik to DNV 19.02.2007 to installfuelcell plant onboard Viking Lady. • DNV prepared draft regulation: FUEL CELL INSTALLATIONS, Pt 6, Ch X - dated 15.12.2007. • Classnotations FC SAFETY og FC POWER • Ourconceptwith analyses, drawings and plans wascheckedagainstthisregulation, FC SAFETY. • Applicationwasfiledwith Sjøfartsdirektoratet, NMD, after all documentationhadbeencheckedout by DNV. • Accept for installationwasrecieved from Sjøfartsdirektoratet 02.09.2009. • Plant installedonboard Viking Lady 08.09.2009. • Concent to connect to switchboardwas given by DNV 03.12.2009. • Viking Lady has nowclassnotationFuelCell Safety

  16. Power and heat at 100 % load

  17. Fuelconsumption -FuelCell Power Plant • A test plant of MCFC from MTU is installedonpsv Viking Lady • Max el-powerproduced: 330 kW • Max heat for recovery: 200 Kw • Consumptionofnatural gas: • Cons. of LNG – onlyel-power: 159 g LNG/kWh • Cons. of LNG – withmax heat recovery: 100 g LNG/kWh • (Compared to a diesel generator: 187 g diesel/kWh)

  18. Emissions - FuelCell Power plant • EmissionofNOx: 0 • EmissionofSOx: 0 • Emissionof CH4: 0 • Emissionofparticles: 0 • Emissionof CO2, withoutrecovery: 377 g/kWh • (Diesel – 36 %) • Emissionof CO2, withrecovery: 235 g/kWh • (Diesel – 60%)

  19. Operationprofile and experiences • FC hadweeklyloadvariationsapprox. 45 – 100% • During the first 180 dayssheproduced 1233 MWhwhereof 782 MWhwasel-power. That is 181 kW in average. • FC has so far more than 14000 hoursofoperation, butwithseveralmonths in so-calledPre-mode, due to adjustments in thepowerelectronics. • So far therearenoindicationsofwear or degradingofthe FC. Shewasinspectedafter 8000 hours.

  20. Application alternatives • As a base load aggregat, (Ready for application ) • El-connection to an AC-switchboard. • With or without heat recovery. • Electric Power SupplyShip. Beingdeveloped as fullyintegrated hybrid system for flexibility and optimum energyutilization. • As mainpowersupply for the shipping market, withfullyintegrated hybrid system with heat recovery and steamturbines.
