Rolls-Royce has been contracted to supply 15 gas engines that will power Norwegian ferry company Torghatten Nord’s five new liquefied natural gas (LNG) fuelled vessels.
The ferries were designed by Multi Maritime and are set to operate between Norway’s Bergen and Stord.
Rolls-Royce will provide C26:33L9AGs engines for the vessels, which feature nine cylinders and are capable of operating on variable speed in order to reduce fuel consumption and emissions.
Each of the engines has an operating speed of 1,000rpm and power of 2430kW.
The Bergen C26:33 series engine reduces total greenhouse gas (GHG) emissions by roughly 20% when compared to similar diesel engines.
They are also compliant with the International Maritime Organisation’s (IMO) Tier 3 requirements and do not require separate exhaust treating systems onboard.
Rolls-Royce marine engines vice-president Kjell Harloff said: “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.
“We have proved that the Bergen lean-burn, pure gas, medium-speed engine range, combined with efficient hull designs, can help customers like Torghatten Nord cut their ships’ emissions and fuel bills significantly.”
Two of Torghatten Nord’s new ferries will be built at the VARD Brevik yard in Norway, while the remaining three will be built at the Tersan Shipyard in Turkey.
The vessels are set to enter service by January 2019.
Torghatten Nord currently operates 33 ferries and ten express boats in Norway, and the company’s current portfolio also includes four LNG ferries equipped with Bergen gas engines.
The ferries were built at the Poland-based Remontowa yard and are now operating on two routes serving Lofoten, Norway.
