Energy-Transition Options for Offshore Vessels

The authors of this paper describe a holistic approach toward integrating alternative fuels and novel prime movers into life-cycle performance of offshore vessels.

A future offshore fleet must comply with emissions regulations and policies that will become increasingly stringent. Making the right decisions with regard to emissions-reduction technologies and preparing vessels for future fuel options to keep the vessels compliant over time is, therefore, of great importance. The cable-lay vessels (CLV) used as a basis for the analysis presented in the complete paper are designed to meet such requirements. The authors highlight types of fuels and drive systems and the consequences of different combinations thereof on vessel design and operational profile.

Alternative Fuels To Reduce Emissions

Several alternative fuels are under consideration to replace fossil fuels currently used in the maritime sector.
