Jul, 06, 2026 Posted by Gabriel MalheirosWeek 202627
Karpowership has reached a new milestone in the expansion of its global fleet with the steel-cutting ceremony for its new Sea Lion-class Powerships.
The ceremony, held at the HSG Sungdong shipyard in South Korea, formally marked the start of construction of the first vessel in a series of four next-generation Powerships. The event was attended by Osman Murat Karadeniz, co-founder and executive board member; Orhan Remzi Karadeniz, co-founder and CEO; and other senior Karpowership executives.
The Sea Lion class represents a new generation of Powerships designed to deliver efficient and flexible electricity generation. Each vessel will have 300 MW of installed capacity and will be equipped with three high-efficiency gas turbines operating in combined-cycle configuration, allowing for better fuel efficiency and lower emissions compared with conventional power generation technologies.
Measuring 136 meters in length and with a draft of 4.5 meters, the Sea Lion can be rapidly deployed across a wide range of coastal locations. The four vessels are scheduled for sequential delivery between January and May 2028.
Powerships are floating thermal power plants equipped with multi-fuel power generation systems. Through integrated onboard substations, they can connect directly to national grids. Their plug-and-play design allows them to begin generating electricity in less than 30 days, provided the necessary infrastructure is available.
Karpowership’s current fleet includes the Khan, Orca, Shark, Mermaid, Seal and Whale classes, with capacities ranging from 30 MW to 600 MW. Sea Lion is the newest class to join the fleet.
