The Rolls-Royce powered Bergen Viking has returned to service following a successful conversion from diesel-electric to LNG-electric propulsion. The Bergen Viking is a 95-meter 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 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.
“We are delighted to take over a renewed and more environmental friendly vessel. Our fleet sails along the long and beautiful Norwegian coast, and visit several ports every day, reducing emissions is an obligation we take very seriously. With the Bergen Viking returning to service we are also looking forward to significant savings in operational costs,” said Kjell Olav Haugland, Managing Director of Bergen Tankers.
John Knudsen, Rolls-Royce, President – Commercial Marine, also 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.”
