Rolls-Royce converts Bergen Viking to LNG power

Rolls-Royce converts Bergen Viking to LNG power

Rolls-Royce informed that Bergen Viking has returned to service following a successful conversion from diesel-electric to liquefied natural gas-electric propulsion.

The retrofit replaced four of the ship’s original six diesel generating sets with two Rolls-RoyceBergen 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 company said in a statement.

The Bergen Viking is a 95-metre long chemical and product tanker 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.

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. Since the introduction of Bergen engines lean burn technology, more than 650 gas engines have been delivered for operation on land and at sea, out of which 63 are marine engines in operation on a range of ships.

The first engines using LNG entered service in 2006 powering doubled-end car ferries.
