Four of the ship’s original six diesel generating sets are replaced with two Rolls-Royce Bergen C6 generating sets.
The LNG fuel containment system and control system is delivered by two off 155m³ fuel tanks configured for redundant propulsion, with crossover options both on bunkering and supply lines.
The Bergen Viking is a 95-metre long chemical and product tanker, part of a total fleet of six vessels owned by Bergen Tankers AS. The vessel was delivered and put in service 2007, supplying diesel and petrol along the Norwegian coastline in trade for Statoil.

John Knudsen, Rolls-Royce, President – Commercial Marine commented:
”The Bergen Viking project demonstrates that LNG is an option not just for new vessels but can be successfully retrofitted into existing ships to deliver significant economic and environmental benefits for owners.”
Rolls-Royce engines fuelled solely by natural gas have been in production since 1991 and have completed over 25 million hours of operation; one million at sea.
The company has developed its expertise in the use of LNG as a marine fuel and secured a range of contracts to power both new vessels and retrofits.
