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
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
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 2011-10-12 Lars-Erik Hellring 11
Stena Saga ME SW Rpm Controlled Pump. (Converted in to values based on shown measurements:) Normal running before installation nearly 600 000 kwh / Year Savings: - ~ 300 000 kwh / Year Lars-Erik Hellring, Stena Line 2011-10-12 Lars-Erik Hellring 12
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 2011-10-12 Lars-Erik Hellring 13
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 197760 kwh/year. - 200 000 kwh/year Solar film Test: 1 Cabin with film. 1 Cabin with out. Difference 6 C 2011-10-12 Lars-Erik Hellring 14
-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.

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
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
