The new vessels feature three high-efficiency gas turbines arranged in a combined-cycle configuration. By prioritizing this design, the company aims to achieve higher fuel efficiency and lower emission profiles than traditional land-based thermal facilities. Each ship measures 136 meters in length and maintains a shallow 4.5-meter draft, allowing for deployment in diverse coastal environments. Delivery for the four-vessel order is staggered between January and May 2028.
Karpowership Launches Construction of 300 MW Sea Lion Powerships
A steel-cutting ceremony at the HSG Sungdong shipyard in South Korea has signaled the start of production for four next-generation Sea Lion class Powerships. These 300 MW floating power plants represent a strategic expansion for Karpowership, aimed at delivering rapid, flexible electricity to coastal markets facing urgent energy shortages.

Karpowership’s floating units serve as mobile utility hubs, equipped with integrated substations that plug directly into national grids. In locations with existing infrastructure, these vessels can begin power delivery in under 30 days. The Sea Lion class will integrate into an existing global fleet that already includes the Khan, Orca, and Whale series, pushing the company’s total operational capacity toward its goal of supporting international energy security. Currently, the firm manages over 8,000 MW of capacity through 45 active Powerships.
