Bergen Tankers’ Bergen Viking has returned to service following a successful fuel conversion, from diesel-electric to LNG-electric propulsion, conducted by Rolls-Royce. The vessel is a 95 m long chemical and product tanker, supplying diesel and petrol along the Norwegian coastline in trade for Statoil. Delivered in 2007, the Bergen Viking is part of a total fleet of six vessels owned by Bergen Tankers AS.
The retrofit process of the Bergen Viking saw four of the ship’s original six diesel generating sets replaced with two Rolls-Royce Bergen C6 generating sets. The LNG fuel containment system and control system is delivered by two 155 m³ fuel tanks configured for redundant propulsion, with crossover options both on bunkering and supply lines.
Rolls-Royce has developed its expertise in the use of LNG as a marine fuel and has secured a range of contracts to power both new vessels and retrofits. LNG is growing in popularity as a marine fuel, and to date, Rolls-Royce has delivered a total of 63 LNG engines to ships.
The company has also signed a contract with Keppel Shipyard in Singapore to supply two all-gas engines for power generation on-board a floating liquefaction vessel, owned by Golar LNG Ltd. The Hilli vessel was a former LNG carrier and is being converted to a floating liquefaction vessel.
Kjell Olav Haugland, Managing Director of Bergen Tankers, said: “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.”
John Knudsen, Rolls-Royce, President - Commercial Marine, added: “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.”
