Samsung Heavy debuts nuclear-powered gas carrier design
Samsung Heavy Unveils Groundbreaking Nuclear-Powered LNG Carrier

At the Gastech event in Milan, Samsung Heavy Industries made headlines by announcing the approval in principle (AiP) for a revolutionary 174,000 cubic meter LNG carrier powered by a nuclear small modular reactor (SMR). This certification, awarded by the American Bureau of Shipping (ABS) and the Liberian Registry, marks a significant milestone as the first of its kind in the world. The innovative vessel promises to redefine maritime energy solutions.
Innovative Propulsion System and Design Features
The nuclear small modular reactor, developed in collaboration with the Korea Atomic Energy Research Institute, will serve as the primary propulsion system for the LNG carrier. This advanced molten salt reactor (MSR) technology uniquely combines nuclear fuel and coolant in a liquid state, enhancing efficiency and safety. Samsung Heavy has invested years into researching nuclear technology, exploring various concepts, including floating nuclear power barges, to push the boundaries of maritime energy.
In addition to the nuclear-powered carrier, Samsung Heavy showcased a newly designed 174,000 cubic meter gas carrier in partnership with Japan’s Mitsui OSK Lines. This innovative vessel features four large hard sails, which are expected to improve fuel efficiency and reduce emissions. Furthermore, the accommodation block has been strategically relocated to the prow of the ship, optimizing space and functionality. These advancements reflect Samsung Heavy’s commitment to pioneering sustainable solutions in the maritime industry.
