182M Research Expedition Vessel Superyacht
The 182m Research Expedition Vessel superyacht, known as REV Ocean, is one of the most ambitious privately funded maritime projects ever conceived: a vessel built not for luxury alone, but to advance scientific understanding of our oceans at a scale no research ship has matched before. Commissioned by Norwegian billionaire Kjell Inge Rokke and designed by world-renowned superyacht architect Espen Oeino, the REV Ocean pushes the boundaries of what a single vessel can accomplish at sea.
What Is the REV Ocean Research Expedition Vessel?
REV Ocean stands for Research Expedition Vessel, and it lives up to that name in every technical detail. At 182 meters in length with a hull beam of 22 meters, it draws 5 meters below the waterline while its decks rise more than 40 meters above the surface. With a gross tonnage of approximately 16,000 GT, it dwarfs most superyachts in both scale and purpose. The vessel was designed by Espen Oeino in collaboration with shipbuilder VARD, combining commercial vessel-grade engineering with superyacht-level interior appointments.
The REV is powered by two Caterpillar engines delivering 2,400 eKW each, capable of pushing the vessel to 17 knots at half load. More impressively, it can cruise non-stop for 21,120 nautical miles, which is roughly 98% of the circumference of the Earth, without refuelling. Eco-friendly features include a slim hull line, an energy recovery rudder system, and a battery package with an integrated exhaust cleaning system.
Scientific Capability and Ocean Research Mission
The REV Ocean was designed from the outset to function as a floating research station. In expedition mode, it can accommodate up to 60 scientists and 40 crew members. It also operates as a luxury charter vessel, hosting 36 guests alongside 54 crew members, with charter revenue helping fund the scientific programme. On board, nine dedicated science laboratories provide space for marine research across disciplines from ocean biology to deep-sea geology.
The vessel carries a remotely operated vehicle (ROV) rated to depths of 19,600 feet, an autonomous underwater vehicle (AUV) for independent mapping, and a Triton submersible capable of bringing three passengers to depths exceeding 7,000 feet. This level of on-board capability places REV Ocean in a category of its own among superyachts and research vessels alike.
Construction Process: A Multi-Country Build
Given the extraordinary scale of the REV Ocean, its construction was divided across multiple VARD shipyard facilities. The hull was built at VARD's Tulcea facility in Romania, then towed to Brattvaag, Norway for outfitting. It then returned to Romania for final finishing, including fairings, deck-laying and accommodation fit-out. This staged international process is standard for vessels of this complexity, but the REV's sheer size made it an exceptional logistical undertaking.
The project is valued at approximately $500 million, making it one of the most expensive privately funded maritime research initiatives ever undertaken. Røkke himself acknowledged there is no conventional economic rationale behind the investment: the REV Ocean exists as a platform for science, education and exploration, with charter income sustaining the ongoing operation.
