Rolls-Royce has signed a deal to supply 15 natural gas engines to Norwegian Ferry Company. The engines will power five Multi Maritime designed LNG ferries operating between Bergen and Stord. The vessels are expected to enter service in January 2019.
“Since the introduction of our first marine gas engines ten years ago, Rolls-Royce has delivered more than 700 gas engines on land and at sea accumulating over 25 million running hours of operating experience,” said Kjell Harloff, Rolls-Royce, Vice President, Engines – Marine.
All 15 engines are C26:33L9AGs, a generating set with nine cylinders in-line. The engines can operate on variable speed to reduce both fuel consumption and emissions. The C-gas engines have an operating speed of 1,000 rpm and power of 2,430kW.
Rolls Royce says the Bergen C26:33 series reduces total greenhouse gas emissions by about 20 percent compared to a similar diesel engine and is IMO Tier 3 compliant without the need of exhaust after treatment system. Engine rooms on gas powered vessels also stay much cleaner, saving operators time and money by reducing the frequency of cleaning tasks and the cost of chemicals. The whole LNG System is designed for safety with double walled stainless steel containment.
