Eidesvik Offshore ASA - Kjell M Sandaker Experiences with Gas and Fuel Cells in ship machinery Incentra – rådsmøte, Haugesund – 2011

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

Sustainable Sea Transportation  What is not sustainable with the use of energy in todays Sea transport ?  Main Answer:  Use of fossile oil as fuel  Harmful emissions to the atmosphere  What are then realistic alternatives to oil ?  What can be possible steps over to realistic alternatives?

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 Queen From January 2008 Viking Lady From May 2009 Viking Lady From May 2009 Viking Energy From April 2003 Viking Energy From April x TBN Delivery x TBN Delivery 2012

Environmental account for producing 1 MWhE, incl. LCA-data NOx-emissionSOx-emission CO 2 -emission Energy consumption Kg MJ

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 hours. Maintenance interval is now set to hours.

Fuel Cells – Third generation maritime gas power technology  Better fuel efficiency  Lower emisssions to the atmosphere  Concept with Molten Carbonate Fuel Cells, MCFC, from MTU

Fuel Cell Installation

Class and authorities  Application for ”approval in principle” was filed by Eidesvik to DNV to install fuel cell plant onboard Viking Lady.  DNV prepared draft regulation: FUEL CELL INSTALLATIONS, Pt 6, Ch X - dated  Class notations FC SAFETY og FC POWER  Our concept with analyses, drawings and plans was checked against this regulation, FC SAFETY.  Application was filed with Sjøfartsdirektoratet, NMD, after all documentation had been checked out by DNV.  Accept for installation was recieved from Sjøfartsdirektoratet  Plant installed onboard Viking Lady  Concent to connect to switchboard was given by DNV  Viking Lady has now class notation Fuel Cell Safety

Power and heat at 100 % load

Fuel consumption - Fuel Cell Power Plant  A test plant of MCFC from MTU is installed on psv Viking Lady  Max el-power produced: 330 kW  Max heat for recovery: 200 Kw  Consumption of natural gas:  Cons. of LNG – only el-power: 159 g LNG/kWh  Cons. of LNG – with max heat recovery: 100 g LNG/kWh  (Compared to a diesel generator: 187 g diesel/kWh)

Emissions - Fuel Cell Power plant  Emission of NOx:0  Emission of SOx:0  Emission of CH4:0  Emission of particles:0  Emission of CO2, without recovery: 377 g/kWh  (Diesel – 36 %)  Emission of CO2, with recovery: 235 g/kWh  (Diesel – 60%)

Operation profile and experiences  FC had weekly load variations approx. 45 – 100%  During the first 180 days she produced 1233 MWh whereof 782 MWh was el-power. That is 181 kW in average.  FC has so far more than hours of operation, but with several months in so-called Pre-mode, due to adjustments in the power electronics.  So far there are no indications of wear or degrading of the FC. She was inspected after 8000 hours.

Application alternatives  As a base load aggregat, (Ready for application )  El-connection to an AC-switchboard.  With or without heat recovery.  Electric Power Supply Ship. Being developed as fully integrated hybrid system for flexibility and optimum energy utilization.  As main power supply for the shipping market, with fully integrated hybrid system with heat recovery and steam turbines.
