Seatrium Limited and its strategic partner Karpowership have signed a contract for the development, major conversion, and integration of Karpowership's third-generation hydrogen-ready Whale Class Powerships, announced on October 23, 2026.

Seatrium Advances Five Powership Conversion Projects

Under the agreement, Seatrium will undertake major conversion work and integration of five Whale Class Powerships, reinforcing both companies' commitment to delivering reliable, flexible, and sustainable energy solutions to meet growing global electricity demand.

Seatrium's scope of work encompasses equipment integration, mechanical completion, and pre-commissioning works. Engineering activities are currently underway, with both parties working closely to advance the project's execution phase progressively. The first vessel in the series is targeted for arrival at Seatrium Tuas Boulevard Yard in December 2027.

The Whale Class Powership

Powerships are floating power plants equipped with hydrogen-ready multi-fuel generation systems and integrated onboard substations that connect directly to national electricity grids. Leveraging Karpowership's plug-and-play design, they can begin generating electricity in as little as 30 days.

The next-generation Whale Class offers Karpowership's highest capacity, engineered to deploy up to 600 MW of immediate, grid-ready power using an ultra-efficient footprint optimised for seamless, continuous fuel supply.

By combining advanced power generation technologies with maritime engineering excellence, these vessels will enhance energy security while providing the flexibility to support diverse market requirements.

Industry Leaders Comment on the Milestone

Mr. Alvin Gan, Executive Vice President, Repairs and Upgrades, Seatrium, said the significant milestone marks Seatrium's first major conversion work and integration of Karpowership's Whale Class Powerships.

He noted that Seatrium is proud to support Karpowership's drive to pioneer innovative floating power solutions and the next phase of its fleet development, bringing its capabilities in complex vessel integration and offshore engineering to the project. He added that Seatrium thanks Karpowership for the continued trust and looks forward to advancing cutting-edge floating solutions that bolster energy resilience worldwide.

Mr. Gokhan Kocak, Chief Technical Operations Officer, Karpowership, said Karpowership has transformed global power generation with its innovative Powership model, delivering fast-track and dependable electricity solutions to millions worldwide.

According to Kocak, the next-generation Whale Class Powerships demonstrate the company's continued commitment to innovation, operational excellence, and energy security. He expressed pleasure at building on the strong partnership with Seatrium, whose proven expertise in complex vessel integration makes them an ideal partner.

Building on a Relationship Established in 2018

The contract marks the next step following an earlier Letter of Intent signed in August 2025, solidifying the long-term partnership between the two companies. That LOI had provided for three FSRU conversions and the potential integration of up to six new-generation Powerships.

Building on a strategic relationship established in 2018, Seatrium and Karpowership share an ambition to deepen their partnership and shape the next generation of energy infrastructure, strengthening energy resilience in Singapore and worldwide.

Since 2018, Seatrium has successfully delivered seven FSRU conversion projects to Karpowership, with the eighth and ninth FSRU conversion projects secured this year.
