The conceptual design of the SMR, which will serve as the propulsion system for the LNG carrier, was developed jointly by Samsung Heavy Industries and the Korea Atomic Energy Research Institute. The design applies molten salt reactor (MSR) technology, which combines nuclear fuel and coolant in liquid form. This development marks a major step in the exploration of nuclear energy applications for maritime propulsion.
Samsung Heavy Industries has been engaged in nuclear technology research for several years. Its projects include studies on various concepts such as floating nuclear power barges, highlighting its focus on diversifying energy solutions for shipbuilding. The company’s work reflects growing interest in nuclear-powered vessels as the shipping industry seeks innovative ways to improve efficiency and reduce emissions.
At the Gastech exhibition, Samsung Heavy also showcased details of another LNG carrier concept. This design, developed in partnership with Japan’s Mitsui OSK Lines, has a capacity of 174,000 cubic meters and introduces several innovative features. It incorporates four large rigid sails designed to enhance wind-assisted propulsion and reduce fuel consumption. Additionally, the accommodation block has been repositioned to the forward section of the vessel, offering both functional and design advantages.
The AiP for the SMR-powered LNG carrier highlights a potential future pathway for energy use in large-scale shipping. Nuclear propulsion could provide continuous, long-duration energy without the need for frequent refueling, positioning it as an alternative for meeting global demands for efficient maritime transport.
The approval also underscores the role of classification societies and international registries in supporting the development of advanced vessel technologies. By granting AiP, ABS and the Liberian Registry have signaled that the design meets key safety and technical requirements at this stage, though further testing and development will follow before commercial deployment.
The new designs presented by Samsung Heavy at Gastech reflect broader efforts across the shipping sector to explore diverse propulsion systems, including nuclear energy, wind-assisted technologies, and other innovations aimed at enhancing operational performance.
With LNG carriers playing a central role in the global energy supply chain, the introduction of alternative propulsion systems is regarded as a significant advancement. Samsung Heavy’s dual focus on SMR-powered propulsion and wind-assisted design solutions demonstrates its strategy of combining cutting-edge research with practical applications to meet evolving market and environmental requirements.
