BOG handling on LNG Carrierwith 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
Laby®-GI Burckhardt Laby®-GIFuel Gas Compressor Type 6LP250-5S Ring sealed4th to 5th stage • Combining LNG BOG and high pressure process compression technology • Optimal selection of compressor sealing system • Fully balanced, single casing, slow speed vertical frame design • Gas-tight compressor casing Labyrinth1st stage Labyrinth1st to 3rd stage Balancingweights < 18 >
