Estimated cost

1 Aurora Take off nozzle on thrusters + new propellers

15% 4 MSEK

2 Aurora and Mercandia VI Powered by re-chargeable batteries instead of diesel-gensets

No exhaust

25MSEK/ vessel

3 Hybrid Power management system to be arranged ”to equlize” power peaks during operation. Ex batteries could be utilized instead of adding diesel gensets needed for power peaks. Concept study for different vessels to evaluate possible savings.

4MSEK

4 Reduction of air resistance Study including CFD calculations for evaluating arrangement of superstructure

Abt 1% 0,5MSEK

5 Optimal bulb design Changed operational profile for a vessel could result in a need to alter the bulb design to reduce the wave resistance.

Abt 3% 3MSEK

6 Propeller design at reduced speed Reduced speed leads to less loaded propeller blades. Taking off two blades of four could give higher propulsion efficiency and less fuel consumption

Solar Window Film:

1 Cabin with film.

1 Cabin with out.

The film is stopping the heat from the sun light going through the window with

around 80 % ,

By this we can then decrease the power on the air-conditions units.

The saving on the compressors on one of our ships was calculated to a saving of

197760 kWh/year.

Difference 6° C

Solar film Test: - ≈200 000 kWh/year

-Original ship design:

Service speed 25,7 knots, installed engine power 39600 kW.

Service speed needed to manage the schedule is 18-20 knots.

-New ship design:

New blades optimized for 20 knots witch gives needed engine power at 24000 kW.

LNG (liquified natural gas)

• Established technology for propulsion of ships

• Long term availability

• Lower emissions: CO2 down 25%, NOX down 85%, SOx and Particles very low

But

• Price

• No infrastructure for distribution

• International regulations, IGF code not in place

• National, regional and local regulations

• Additional investment in new-buildings and retrofit

• Cost for conversion of existing fleet

Conversion of a Ropax Göteborg - Fredrikshamn, propulsion power 4 x 6500 kW

Conversion of main engines ~ 450 – 520 USD/kW

Investment in tanks, piping, etc ~ 450 – 520 USD/kW

Other equipment ~ 400 USD/kW

Main engines ~90 MSEK

Tanks, cool box, etc ~90 MSEK

Misc ~70 MSEK

---------------------------------------

~ 250 MSEK

The ship’s cargo capacity will be reduced with abt 15%

A RoPax new building project equipped for LNG propulsion will be 15 - 20%

more expensive

Methanol as a marine fuel Conversion factor energy equivalence Methanol and Marine diesel oil

▪ Exhaust emissions – Methanol equivalent to LNG (SOx, NOx, PM)

▪ Green House Gas – Methanol leads towards Zero vision. (Bio- and electro generated)

▪ Energy security – diversifies Europe’s energy imports

▪ Economy per ship – ~4 million USD of added yearly fuel cost avoided
