Sustainable Sea Transportation

What is not sustainable with the use of energy in todays Sea transport ? Main Answer:

Use of fossile oil as fuelHarmful emissions to the atmosphere

What are then realistic alternatives to oil ? What can be possible steps over to realistic alternatives?

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.

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

Test installation, schematic

Fuel Cell Installation 08.09.09

Class and authorities

Application for ”approval in principle” was filed by Eidesvik to DNV 19.02.2007 to install fuel cell plant onboard Viking Lady.

DNV prepared draft regulation: FUEL CELL INSTALLATIONS, Pt 6, Ch X - dated 15.12.2007.

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 02.09.2009. Plant installed onboard Viking Lady 08.09.2009. Concent to connect to switchboard was given by DNV

03.12.2009. 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 14000 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.

Thank you for the

attention
