15. BOG handling on LNG Carrier with ME-GI
ME-GI can be applied with:
100% reliquefaction system,
partial reliquefaction system,
no reliquefaction system at all
Selection of a reliquefaction system is typically dependent on vessel requirements with regards to:
Sailing profile
Proportion of time with HFO or Gas operation
Amount of BOG produced from cargo tanks
Value of BOG and/or LNG
…and not a requirement of ME-GI
