World’s largest yacht REV Ocean resumes construction with 12m extension

The 182.9-metre, record-breaking research expedition vessel REV Ocean has resumed construction at one of Vard's facilities in Norway with an expected new length of 194 metres. BOAT International has confirmed that delivery is scheduled for February 2025, with REV Ocean expected to become fully operational from Q4 2026.

Construction on REV Ocean paused in 2021, but the shipyard has affirmed that its vision for the vessel remains "unchanged" and work will be done to improve its functionality. This includes an amidships extension of 12 metres and a rearranged layout that sees "more space and increased science capacity in the main hangar of the vessel".

Although it will not be considered a fully-fledged superyacht, the vessel has been developed in collaboration with leading superyacht designer Espen Øino.

Owner and Norwegian businessman Kjell Inge Røkke previously explained: "REV [Ocean] will be a platform for gathering knowledge. I would like to welcome researchers, environmental groups, and other institutions on board, to acquire new skills to evolve innovative solutions to address challenges and opportunities connected to the seas."

Advanced oceanography equipment will be fitted on board, allowing the vessel to survey marine areas, currents, the seabed, fish, animals and plant life.

As is fitting for an environmentally conscious project, REV Ocean has been designed to be as fuel efficient as possible, with an energy recovery rudder system, medium speed engines, a direct drive diesel-electric propulsion system, and an exhaust cleaning system.

Other key onboard features include a multifunctional cargo deck and storage for an autonomous submersible, as well as laboratories and an auditorium. Accommodation was initially envisioned for 36 guests and 54 crew members.

"We eagerly await delivery of this unique research and expedition vessel. We thank all our team members, friends and partners for their patience during this time and look forward to finally setting sail," said a spokesperson for the shipyard.
