LNG Bunkering

D6. Decarbonization, emissions and alternative fuels

Definition

Process of supplying liquefied natural gas as marine fuel.

LNG bunkering supplies liquefied natural gas as fuel at about minus 162 degrees Celsius by truck-to-ship, shore-to-ship, or ship-to-ship transfer, following the IGF Code and the IGC-derived practice from LNG carriers. It needs cryogenic transfer arms, vapor return, and careful cool-down to avoid thermal shock, plus boil-off management. A growing bunker-vessel fleet at hubs such as Rotterdam, Singapore, and Zeebrugge supports the LNG-fueled fleet, with simultaneous operations protocols allowing bunkering during cargo work under controlled conditions.
