Norwegian shipbuilder Ulstein has unveiled THOR, a groundbreaking 149-meter superyacht concept designed to set a new standard for sustainability at sea. More than just a luxury vessel, THOR is envisioned as a floating power station, providing clean energy to support zero-emission operations in some of the world’s most remote locations.
At its core, THOR features a state-of-the-art molten salt reactor powered by thorium—a naturally abundant and low-radioactivity element. This next-generation reactor is engineered to produce 20 megawatts of emission-free electricity, sufficient to recharge electric expedition ships like Ulstein’s own SIF concept. THOR embodies a vision of a global fleet of clean-energy vessels operating silently without environmental impact.
The yacht’s design prominently showcases Ulstein’s signature X-BOW technology, which enhances fuel efficiency and stability even in the harshest marine conditions. Its sleek lines and purposeful profile reflect THOR’s dual identity as a luxury superyacht and a sophisticated scientific platform.
Classified as a Replenishment, Research, and Rescue (3R) vessel, THOR is equipped for a variety of missions. Features include helicopter pads, autonomous surface vehicles, cranes, and modular laboratories. A dedicated lecture lounge further emphasizes her role as a floating research center, capable of supporting scientific expeditions and humanitarian efforts alike.
Though interior details remain sparse, the design is expected to highlight a minimalist Scandinavian style that blends functionality with subtle luxury. Sustainability will be a key focus, with eco-friendly materials and energy-saving systems integrated throughout without compromising comfort.
THOR is more than a yacht—it is a catalyst for change. By integrating thorium-based nuclear power with a mission-driven design, Ulstein is positioning itself at the forefront of the marine industry’s transition to sustainable innovation. Whether advancing scientific exploration in polar regions or powering electric vessels far from shore, THOR could herald a new era for superyacht technology.
