Fast uptake in LPG carrier sector

The industry standard

‒ Applied to almost 100% of Very

Large Gas Carriers (VLGCs) ordered

in 2020.

‒ Several references within handy-size

and mid-size LPG carriers as well,

however slightly slower transition

compared to VLGCs.

ME-GI summary

Second-to-none ultra low methane slip

‒ Impeccable cylinder condition and high combustion stability with with no load, methane

number or ambient limitations in dual fuel mode operation.

‒ Low fuel consumption obtained by high thermal efficiency and low SPOC

‒ Maximum gas operation availability ensured by Gas Cylinder Cut-Out (CCO)

‒ Maximized reliability with simplified design and significant operational benefits

‒ References on LNG Carriers, Bulk Carriers, Tankers, PCTC, Container Vessels and Con-Ro
