The boil-off gas represents 0.1% - 0.25% of the ships capacity per day. Tanks need to be maintained at a steady pressure. If the pressure in tanks gets too high, relief and safety valves open, venting the boil-off into the atmosphere until the excess pressure is relieved. Due to the fact that on-board LNG re … See more A marine LNG engine is a dual fuel engine that uses natural gas and bunker fuel to convert chemical energy in to mechanical energy. Due to natural gas’ cleaner burning properties, the use of natural gas in merchant ship … See more LNG shipping first became a possibility in 1959 when the Methane Pioneer, a converted WWII freighter safely transported Liquefied Natural Gas into the United Kingdom. … See more Samsung's Supreme was a Mark-III type LNG container ship that was the largest of its kind.
