Singapore shipbuilder Seatrium has secured a contract from Turkey-based Karpowership to develop, carry out major conversions on and integrate five power generation ships designed to be hydrogen-ready, the two companies confirmed on Friday, October 23.
Each vessel is designed to deliver up to 600 MW. Alongside the conversion work, Seatrium's scope includes integrating equipment, completing mechanical work and conducting pre-commissioning.
Engineering is underway, and the first vessel is targeted to arrive at Seatrium’s Tuas Boulevard Yard in December 2027.
The floating power plants will feature multi-fuel generation systems prepared for hydrogen use as well as integrated onboard substations that will provide direct connections to national electricity grids.
Karpowership said its plug-and-play design will enable the plants to start generating electricity in less than 30 days, provided the necessary infrastructure is in place.
Karpowership's published specifications list the series as a self-propelled 500MW–600MW design with three engines, six gas turbines, and accommodation for 46 people per vessel.
Seatrium and Karpowership have worked together since 2018, mainly on floating storage and regasification unit (FSRU) conversions.
The new contract followed an August 2025 letter of intent that covered four powership integrations with an option for two more, as well as three FSRU conversions.
