A study led by Vard, a subsidiary of Italy’s Fincantieri, has found that nuclear-powered offshore vessels are technically feasible, confirming that small fourth-generation nuclear reactors can be integrated into dynamically positioned vessels while meeting safety, redundancy and operational requirements.
Results from the NuProShip II research and innovation project show that nuclear propulsion can support DP2 power architectures, with potential adaptability to DP3 standards, offering high operational reliability alongside the possibility of zero greenhouse gas emissions and extended operating endurance.
As part of the project, Vard completed a concept design for a nuclear-powered offshore construction vessel based on an existing VARD reference design. The study evaluated the integration of a helium gas-cooled nuclear reactor as the primary power source and assessed impacts on vessel layout, safety systems and overall performance.
The project also examined alternative energy balancing solutions, including super-critical CO₂ turbines and thermal battery systems, which could complement nuclear propulsion and reduce reliance on conventional electrical batteries.
Short for ‘Nuclear Propulsion in merchant Shipping’, the NuProShip II study was led by Vard Design and conducted in cooperation with classification society DNV, Emerald Nuclear, Vard Electro, offshore vessel owner Island Offshore, and the Norwegian University of Science and Technology (NTNU), which
