Fifteen Engines for Five New Torghatten Nord Vessels,
MAN Cryo Is to Furnish FGSS/Fuel Gas Supply Systems

Rolls-Royce has publicized a pact to supply 15 of its dedicated-natural gas C26:33 series Bergen engines to power five new ferries for Tromsø, Norway-based Torghatten Nord. updated June 6

The liquefied natural gas-fueled ferries will have electric drivelines with a battery system “arranged with capability for fast charging from shore,” says designer Multi Marine, of Førde, Norway.

Two of the new 440-foot (134-meter), DNV GL-classed, MM125FD LNG ferries will be built at the Vard Brevik yard in Norway and three at the Tersan Shipyard in Turkey, Rolls-Royce reports. “The vessels are expected to enter service in January 2019,” the company says.

Five ‘Identical’ Ships

MAN Cryo said in April that it will provide its FGSS/fuel gas supply system for the vessels being built by Vard. The LNG supply system consists of a 175-cubic-meter (46,200-gallon) vacuum-insulated storage tank, MAN said, “with auxiliary equipment including an LNG vaporizer, a pressure build-up unit and a bunker station.”

MAN will supply its FGSS for the vessels built in Turkey too, says Kim Espen Tepstad, LNG engine sales GM at Rolls-Royce Marine. “All five vessels shall be identical,” he told F&F.

‘Bergen C26:33 series engines are in operation across a range of vessel types,’ Rolls-Royce says.

“Since the introduction of our first marine gas engines ten years ago, Rolls-Royce has delivered more than 700 gas engines on land and at sea accumulating over 25 million running hours of operating experience,” Rolls-Royce marine engines VP Kjell Harloff said in a release.

Proved’

“We have proved that the Bergen lean-burn, pure gas, medium-speed engine range, combined with efficient hull designs, can help customers, like Torghatten Nord, cut their ships’ emissions and fuel bills significantly,” he said.

All 15 engines for Torghatten Nord are C26:33L9AGs, Rolls says: “a generating set with nine cylinders in-line.” The units can operate on variable speed to reduce both fuel consumption and emissions. Power is 2,430 kilowatts, or nearly 3,260 horsepower.

Not the First for Torghatten Nord

“Bergen C26:33 series engines are in operation across a range of vessel types including cargo vessels, PSVs and tugs as well as passenger vessels,” states the Rolls-Royce release.

Also according to the Rolls-Royce announcement, Torghatten Nord currently has 33 ferries and yen express boats in operation in Norway. Four earlier LNG ferries, with Bergen gas engines, were built at the Remontowa yard in Poland.
