4th Feb 2011 07:19

Power systems developer Rolls-Royce has signed a £20m contract to supply engines and propulsion equipment for four gas-fuelled ferries to be built for the Norwegian operator Torghatten Nord.Rolls-Royce said the new vessels will be the first to feature the company's Hybrid Shaft Generator (HSG), which produces electrical power with reduced fuel consumption and emissions. HSG enables engine and propeller speed to be varied in step-changes, thereby reducing fuel consumption.The ferries will also include Rolls-Royce Bergen gas engines and the company's integrated propeller and rudder system (Promas) that reduces drag and increases thrust.These technologies will combine to reduce CO2 emissions by 40% compared to conventional vessels.The vessels will be built by the Remontowa Shipyard in Gdansk, Poland for delivery in the second half of 2012.
