LPG as marine fuel

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
