Rolls-Royce: All-Gas Keeps Engine Clean
Rolls-Royce Marine has shared some dramatic photos taken during a major overhaul of the liquefied natural gas-fueled engines on the Bergensfjord ferry operated by Norway’s Fjord1.
Fjord1 is a true pioneer in LNG, commissioning the first-ever LNG ferry, the Glutra, in 2000.
Fjord1’s Bergensfjord entered service in 2007, powered by first-generation dedicated-LNG Bergen engines: two KVGS12G and two KVGS16G units generating a total of 12,500 kilowatts, advises Rolls-Royce Marine general sales manager Odd Magne Horgen – more than 16,700 horsepower.
Fjord1’s 426-foot, dedicated natural gas, Rolls-Royce Bergen-powered Bergensfjord ferry entered service in Norway in January 2007.
The photos above and below show the vessel’s the crankcase and engine rooms during a major overhaul following 43,000 hours of service.
The Original Oil
“Still white and clean,” Horgen says. “No oil mist.”
And, he told HHP Insight, “They are still using the same main lube oil that was filled on the engines when they were started back in January 2007.”
The Fjord1 Bergensfjord engines have now logged more than 50,000 hours, Horgen reports.
