Abstract
A primary stream of boiled-off natural gas taken from the ullage space of a liquefied natural gas storage vessel is compressed by a compressor. A flow of liquefied natural gas taken from the storage vessel is partially and forcedly vaporised in a vaporiser 36 so as to form a secondary stream of natural gas containing unvaporised liquefied natural gas. Unvaporised liquefied natural gas is disengaged from the secondary stream in a phase separator. The secondary stream is mixed with the compressed primary stream to form a supply of natural gas fuel. The fuel supply may be formed and used on board an ocean-going LNG tanker.
