The British Emerald, the first in a series of dual-fuel diesel-electric gas ships, measures 155,000 cubic metres, and is said to be more environmentally friendly than standard LNGCs.
The dual-fuel technology allows the diesel engines to run on ‘boil-off’ gases from the cargo tanks or on on conventional diesel fuel. The vessel will burn 40 tonnes per day less than a conventional LNGC of similar size, which would burn about 180tpd.
The vessel, which is 288m long and 44.2m wide, is powered by four diesel-electric engines, and is equipped with a bow thruster to assist in mooring operations.
A 23-strong crew will put the LNGC through a 10-day commissioning program before entering service.
The British Emerald is the first of a fleet of four ‘gem’ class LNG carriers, and the other three vessels, which includes the British Diamond, British Ruby and British Sapphire, will be delivered in 2008.
