Why Gas Power in marine machinery?

Reduced air pollution emissions – better air quality

Reduction in emission of NOx

Reduction in emission of Particles

Reduction in emission of SOx

Reduction in emission of climate gasses

Better Fuel economy

Offers wider possibilities for new technology development for even more environmental friendly solutions

Emission of climate gasses, CO2 and CH

4

• The CO2-emission is approx. 20 % less than in diesel mode

• The CH4-slip will, however, reduce the gain, especially at low load.

Latest generations of DF engines are designed for minimizing also

CH4-slip. The CO2-equvivalent emissions will be below the levels of

same for diesel engines

Wärtsilä

2 x 6L34DF +

2 x 6L20DF

The engines are dual-fuel type and can operate in gas mode or diesel

mode. Normally approx. 95 % of the energy production is in gas mode

Operation

No limitation to

operations due to the

gas power installations

Gas Power Economy

• Additional investments for a gas powered supply ship is in the

order of 8 – 10 % of building cost

• In Norway about 80 % of these additional costs are

compensated by the NOx-Fund

• Fuel costs make a difference: Typically one year operation of a

supply vessel will need:

• In gas mode: 2300 tonn LNG + 160 tonn MGO or

• In diesel mode: 2650 tonn MGO

Fuel consumption and emissions

(first generation gas power)

Viking Energy – typical figures for one year operation:

Total energy production 14,4 GWh

Consumption of LNG 2880 T

Consumption of MGO 200 T

Emission of NOx 21,2 T

Reduction in NOx emission 87,6 %

Emission of CO2 8533 T

Reduction of CO2 20 %

Emission of SOx 2,1 T

Emission of particles 0

Maintenance

• LNG and natural gas systems have proven very reliable. We have

more than 22 ship years of operation without technical off-hire

due to the gas installations

• Cost reduction for mechanical maintenance and lube oil

• Cost increase for control systems and electro systems

• After 10 years of operation for our first LNG fuelled vessel, we

clearly see reduction in maintenance cost compared with diesel

operation

LNG supply infrastructure

Development of the LNG supply and distribution

infrastructure is going very fast in Norway.

• New engine configuration, 2 large + 2 small

• New hull shape for best fuel economy at operational speed 12-13 knots

• Power Consumption Tuning, «Econometer»

Viking Prince (delivered 2012)

Second generation LNG technology

with belonging improvements on

emissions and consumption

..And also approx. 25 % reduced fuel

consumption versus earlier solutions

Average Fuel Consumption

Average daily fuel consumption for Eidesvik’s PSV fleet (per vessel)

showing approx 20% reduction in 4 years. Two major contributors:

- Technology & Design (Engines setup, Hull, Autopilot etc.)

- Focus and education of personnel (Energy Efficiency Program)

This would have been

difficult if it wasn’t for

Eidesvik’s LNG history;

Our employees have

become more focused on

environmental friendly

solutions, which in turn

also makes fuel saving a

major target in the

everyday operation of the

vessels

Concluding remarks

• A switch to LNG only does not solve all problems with emission and

security of fuel supply, but gas power opens up for new technologies

for energy efficiency that do not exist with diesel

• Several other energy saving technologies and measures should be

added

• Education and training of personnel is important for as well safety as

fuel economy

• Crew participation in the development through ongoing campaigns

show results
