DNV announced that HD KSOE has received an Approval in Principle (AiP) for a 15,000 TEU container vessel concept powered by Small Modular Reactor (SMR) technology. The design represents a significant advancement in maritime propulsion, targeting enhanced efficiency and reduced environmental impact within the shipping industry.
According to DNV, the SMR-based vessel is engineered to reach speeds of 24 knots, incorporating a supercritical CO₂ power generation system that provides higher thermal efficiency and a more compact equipment layout compared to conventional steam-based systems. This innovative integration highlights growing industry interest in nuclear energy as a potential long-term solution for decarbonising large ocean-going ships.
The vessel design includes advanced shielding and containment systems intended to ensure reactor integrity and operational safety under extreme conditions such as collision, grounding, or sinking. These safety measures align with the International Maritime Organization (IMO) safety frameworks and SOLAS Chapter VIII regulations, providing a clear pathway for potential compliance in future nuclear-powered commercial vessels.
In developing the concept, HD KSOE collaborated closely with DNV to validate the technical and safety foundations of the design. The partnership included a Hazard Identification (HAZID) workshop in Oslo during May 2025, focusing on identifying and mitigating possible risk scenarios associated with nuclear propulsion in marine environments.
The AiP confirms the feasibility of applying SMR technology to container ships and supports the ongoing evaluation of nuclear energy as a viable alternative to conventional marine fuels. With the certification, both organisations continue to explore the next stages of technical verification and classification standards for nuclear-powered shipping, a sector that has seen limited activity in recent decades.
