Nuclear reactors may soon power offshore construction vessels

The NuProShip II research project, led by VARD (a Fincantieri Group subsidiary), has demonstrated the technical feasibility of integrating small fourth-generation nuclear reactors into offshore dynamic positioning (DP) construction vessels. The project developed a concept design based on an existing vessel, incorporating a helium gas-cooled nuclear reactor as the primary power source. This design meets stringent safety and redundancy standards required for DP2 and potentially DP3 power architectures, promising enhanced operational safety, reliability, and emissions-free power for extended offshore operations without the need for refueling. The study also explored advanced energy storage options like supercritical CO2 turbines and thermal batteries to complement nuclear power. In addition to technical validation, NuProShip II addressed radiological safety, containment, and risk management to meet civilian nuclear regulations, emphasizing transparency and public acceptance. The initiative, funded by the Research Council of Norway, reflects the country's commitment to sustainable maritime innovation and will conclude in 2026. Post-completion, research will continue under the
