ROLLS-ROYCE COMPLETES NATURAL GAS RETROFIT OF BERGEN VIKING

The Rolls-Royce powered Bergen Viking has returned to service following a successful conversion from diesel-electric to Natural Gas (LNG)-electric propulsion.
LNG is growing in popularity as a marine fuel, and to date Rolls-Royce has delivered a total of 63 natural gas engines to ships. Natural gas reduces Nitrogen Oxide (NOx) emissions by about 90 per cent while Sulphur Oxide (SOx) and particulates emissions are negligible. Gas engines also reduce CO2 emissions by 25 to 30 percent in general, compared to diesel or heavy fuel oil powered vessels. Emissions from Rolls-Royce gas engines are already within the limits of International Maritime Organisation (IMO) Tier III environmental legislation, due to come into force in 2016.
The retrofit replaced four of the ship’s original six diesel generating sets with two Rolls-Royce Bergen C6 generating sets (Engine types 2 x C26:33L6A Gas). 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.
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, said: “The Bergen Viking project demonstrates that natural gas 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.”
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.
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. The first engines using natural gas entered service in 2006 powering doubled-end car ferries. The 63 Bergen Gas-fuelled marine engines are now in operation on a range of ship types including coastal cargo ships, tankers, cruise ferries, tugs and offshore support vessels.
Rolls-Royce has developed its expertise in the use of natural gas as a marine fuel and secured a range of contracts to power both new vessels and retrofits.
These include a collaboration agreement with Spanish energy company Gas Natural Fenosa to develop and install a pure-gas Bergen engine aboard the Baleària-operated ferry Abel Matutes a 29,670 tonne ROPAX ferry, delivered in 2010. The contract gives Rolls-Royce its first reference for a pure-gas engine installation on a European-flagged ferry operating outside of Norwegian waters.
The Bergen engine range is produced in Norway by Rolls-Royce Power Systems, part of the Group’s Land & Sea division.
