Ulstein THOR Heralds a New Era of Emission-Free Yachting
Norwegian shipbuilder Ulstein has introduced THOR, an innovative 149-metre superyacht concept set to redefine sustainability at sea. Marking a bold step into the future of maritime design, THOR is more than just a yacht, it is envisioned as a floating power station, capable of delivering clean energy to support zero-emission operations in some of the planet’s most remote regions.
At the heart of THOR lies a cutting-edge molten salt reactor fuelled by thorium, a naturally abundant, low-radioactive element. This next-generation reactor is designed to generate 20 megawatts of emission-free electricity, enough to recharge electric expedition vessels, such as Ulstein’s own SIF concept. It’s a vision not just of a single ship, but of a fleet of clean-energy vessels roaming the globe without leaving a trace.
Visually, THOR is unmistakably Ulstein. The design incorporates the shipbuilder’s iconic X-BOW, a forward-thinking feature known for improving fuel efficiency and stability in harsh marine environments. Sleek lines and a purposeful silhouette reflect her unique dual role as a luxury vessel and a serious piece of scientific infrastructure.
Classified as a Replenishment, Research, and Rescue (3R) ship, THOR has been conceived with capability in mind. She will be equipped with helicopter pads, autonomous surface vehicles, cranes, and modular laboratory spaces. A dedicated lecture lounge further signals her role as a floating research hub, equally adept at hosting scientists and supporting humanitarian missions.
The interior, while not yet fully detailed, is expected to embrace a minimalist Scandinavian aesthetic, balancing functionality with understated luxury. With sustainability at its core, every element is likely to prioritise eco-conscious materials and energy efficiency without compromising on comfort.
THOR represents more than a yacht, it is a platform for change. With its ambitious integration of thorium-based nuclear power and mission-driven design, THOR positions Ulstein at the forefront of the marine industry’s shift towards a sustainable future. Whether enabling scientific research in polar regions or supporting electric vessels far from port, this concept could mark the dawn of a new era in superyacht innovation.
