Samsung Heavy Industries (SHI) has received an approval in principle (AiP) for its molten salt reactor (MSR)-powered 174,000-m3 liquefied natural gas carrier. The small modular reactor (SMR) will be jointly developed by SHI and Korea Atomic Energy Research Institute (KAERI).
SHI announced it had received the AiP on 9 September at Gastech 2025, which took place between 9-12 September in Milan, Italy.
The MSR-powered LNG carrier is receiving technical certification from American Bureau of Shipping (ABS) and Liberian flag state. The MSR technology utilises a liquid mixture of molten salt (liquid reactor fuel) and coolant to improve stability and energy efficiency.

More certifications
During GasTech, SHI also obtained multiple technical certifications for various eco-friendly digital integration technologies, including AiPs from DNV for its 80,000-m3 liquefied hydrogen (LH₂) carrier design, which has been optimised to reduce size and prevent heat influx, and from Lloyd’s Register (LR) for its LNG carrier equipped with wind-assisted propulsion.
Five global classification societies granted approval for “Snap Wind Float”, SHI’s newly developed floating offshore wind substructure capable of supporting up to 15 MW wind turbines. The structure features a modular brace system inserted between columns, significantly reducing construction time for offshore wind installations.
In addition, SHI signed an agreement with Singapore-based shipping company Eastern Pacific Shipping (EPS) to implement SHI’s DT-SLM (Ship Lifecycle Management solution), which uses digital twin technology to enable performance monitoring and provide predictive preservation of key ship equipment.
