GEM class
British Ruby
These ships can carry a cargo of 155,000 cubic metres of liquefied natural gas (LNG). These vessels are equipped with a dual-fuel diesel-electric (DFDE) propulsion system that increases their fuel efficiency and reduces fuel costs
The dual-fuel technology allows the diesel engines to run on "boil-off" gases from the cargo tanks or on conventional diesel fuel, consuming about 40 tonnes per day less fuel than an LNGC of similar size with a conventional steam turbine propulsion system. Four diesel-electric engines provide greater propulsion redundancy and a bow thruster assists mooring operations.
The builder of these ships is Hyundai Heavy Industries Limited in Korea. They are British-flagged, with Douglas, Isle of Man as their port of registry. Their classification society is Lloyds Register. BP operates these ships, providing its own crews.
