Rolls-Royce to power Norwegian LNG ferries

“Rolls-Royce is a global leader in the supply of energy efficient technologies which enable ship operators to address the environmental challenges they face. These ferries will combine a range of cutting edge technologies to deliver significant improvements in fuel efficiency and reductions in emissions,” said Oddbjørn Eliassen, president of Rolls-Royce’s merchant business.

These ferries 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 gas engines and the company’s innovative integrated propeller and rudder system (Promas) that reduces drag and increases thrust.

HSG is an advanced electrical system that enables a step-change in ship efficiency by varying engine and propeller speed to reduce fuel consumption and consequently lower emissions (40 per cent reduction in CO₂ emissions, compared to conventional vessels). 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.
