Acta Marine's methanol-fuelled CSOVs

In 2022, Ulstein Design & Solutions AS signed a design contract on two methanol-fuelled CSOV vessels for Acta Marine, and a contract for two more followed in 2023. The vessels will be constructed at the Tersan yard. Follow the progress here.

The CSOV designs for Acta Marine are the first to introduce the ULSTEIN TWIN X-STERN. These Construction Service Operating Vessels are based on the ULSTEIN SX216 design. The vessels will be delivered with dual-fuel methanol/diesel power generators.
