These ships use pressurized tanks, and the bunkering is done by spraying the liquid in from the top of the tank. This spray cools down the vapour and liqufies some it, so overall pressure is not increasing in the tank.
LNG is being promoted as an environmentally friendly fuel. When this ship loads the fuel, what happens to the vapour that is being displaced by the liquid. Is it being vented to atmosphere or used on board?
Venting LNG is prohibited by maritime laws, the vapour from the tanks can be used as fuel for burning in steam generators.
