Bergen Viking Goes Green
The Rolls-Royce powered oil/chemical tanker Bergen Viking has returned to service following a conversion from diesel-electric to liquefied natural gas (LNG)-electric propulsion.
The retrofit replaced four of the ship’s original six diesel generating sets 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, owned by Bergen Tankers supplying diesel and petrol along the Norwegian coastline in trade for Statoil. Delivered in 2007, the vessel is part of a total fleet of six vessels owned by Bergen Tankers AS.
”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,” John Knudsen, Rolls-Royce, President – Commercial Marine, said.
