Rolls wins £20m contract to power fuel efficient ferries
1 min read
Rolls-Royce has signed a £20 million contract to supply engines and propulsion equipment for four gas-fuelled ferries to be built for the Norwegian operator Torghatten Nord AS, it was announced today (4 February).
The vessels will be the first in the world to feature the Rolls-Royce Hybrid Shaft Generator (HSG), which produces electrical power with reduced fuel consumption and emissions. They will also include lean-burn Rolls-Royce Bergen-built gas engines and the company's integrated propeller and rudder system (Promas) that reduces drag and increases thrust.
The global power systems company said these technologies will combine to offer an unrivalled environmental performance, including a 40% reduction in CO2 emissions, compared to conventional vessels.
Rolls-Royce president - merchant Oddbj¸rn Eliassen the ferries will combine a range of cutting edge technologies to deliver significant improvements in fuel efficiency and reductions in emissions.
HSG is an advanced electrical system that enables a step-change in ship efficiency by varying engine and propeller speed to reduce fuel comsumption and consequently lower emissions. Ships' engines traditionally operate at a fixed speed when conventional shaft generators are in use, but HSG allows shaft speed to be reduced, while maintaining a constant frequency for the electrical supply throughout the ship.
The ferries will serve two routes across Vestfjorden in Lofoten in the north of Norway, a stretch of water known for its harsh conditions. They will be built by the Remontowa Shipyard in Gdansk, Poland for delivery in the second half of 2012.
