9 Fuel Efficiency Project Energy saving Estimated cost 1 Aurora Take off nozzle on thrusters + new propellers 2 Aurora and Mercandia VI Powered by re-chargeable batteries instead of diesel-gensets 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. 4 Reduction of air resistance Study including CFD calculations for evaluating arrangement of superstructure 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. 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 15% 4 MSEK No exhaust Abt 1% Abt 3% Abt 3% 25MSEK/ vessel 4MSEK 0,5MSEK 3MSEK 0,3MSEK

10 Examples of Started ESP Projects: - Frequency controlled Pumps and Fans. - Installation of propellers with new design, higher efficiency. - Installation of different types of ETA Pilots. - Installation of Exhaust boilers. - Sun Screen film on windows. - Underwater area refreshment, keep the hull in best shape. - Upgrade of fluorescent-lamp eq to new electronic ballasts. - Main Engine Optim. (TC, Fuel PP, Timing, Scav.Air Temp. Reg. - Optimize Ship Schedule. - Training, education of Officers, discussion of New Ideas. Lars-Erik Hellring, Stena Line 10

11 Frequency (rpm) controlled Equipment: - Pumps, Cooling/Heating systems Sea Water Cooling Pumps (FW, SW, Boiler water, Chiller Water..) - Fans (Engine room, accommodation, galley..) - Hydraulic EQ (Steering gears, Ramp EQ..) Lars-Erik Hellring, Stena Line Lars-Erik Hellring 11

12 Stena Saga ME SW Rpm Controlled Pump. (Converted in to values based on shown measurements:) Normal running before installation nearly kwh / Year Savings: - ~ kwh / Year Lars-Erik Hellring, Stena Line Lars-Erik Hellring 12

13 Solar Window Film: Denmark Terminal: Instead of bying expensive glass, we by ordinary and mount Solar film Better price and better performancy Lars-Erik Hellring, Stena Line Lars-Erik Hellring 13

14 Solar Window Film: 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 kwh/year kwh/year Solar film Test: 1 Cabin with film. 1 Cabin with out. Difference 6 C Lars-Erik Hellring 14

15 -Original ship design: Service speed 25,7 knots, installed engine power kw. Service speed needed to manage the schedule is knots. -New ship design: New blades optimized for 20 knots witch gives needed engine power at kw. Lars-Erik Hellring, Stena Line Lars-Erik Hellring 15

16 Consumption per Trip 2006 / 2007 in %: Base line 2006 = 100% -Saving: Average after propeller change according to 2006: Around 16 % Lars-Erik Hellring, Stena Line

17 Stena Line future challenges Environmental legislations in SECA, 0,1% sulphur Nox regulations Peak oil = Increased fuel prices Global Warming Alternatives: Alternative fuel, exhaust gas cleaning (HFO) or MDO, energy efficiency? Risk: Competition from other transport solutions

20 LNG (liquified natural gas) Established technology for propulsion of ships Long term availability Lower emissions: CO 2 down 25%, NO X down 85%, SO x 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

21 LNG operation of ferries Conversion of a Ropax Göteborg - Fredrikshamn, propulsion power 4 x 6500 kw Conversion of main engines ~ USD/kW Investment in tanks, piping, etc ~ 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
