Conclusions
Ø Almost all vessel typologies have alreadyreferences with LNG as fuel
ØWärtsilä low-pressure, dual-fuel technology ensuresemission compliancy without after treatment.
Ø Fuel flexibility is a viable solution for improvingCapEx and OpEx where LNG is available.
Ø Dual-Fuel vessels have a higher asset value duringtheir complete lifetime thanks to their operationalflexibility
