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
