Changes in propulsion systems
Initially, all LNG Carriers built with Steam Turbin e:Reliable, but
Low efficiency
Optimized for one dedicated speed
Since 2005/2006, DF-DE engines as a basis of designImproved global efficiency
Improved redundancy (4 DFDE + 2 Electric motors)
Flexibility according to power demand
More cargo delivered
Recently, Slow Speed engines with gas burning optio ns ME-GI (MAN) and X-DF (Wartsila)
