World's biggest yacht REV Ocean

REV Ocean is a research and expedition vessel (REV) and super yacht built by VARD shipyards in Tulcea, Romania. She was designed by Espen Øino with an interior by H2 Yacht Design, and was initially launched on 22 August 2019. She will be fitted out at other VARD shipyards and is scheduled to be delivered in 2021. At 183 metres (600 ft) in length and at 17,440 gross tons, she is the longest motor yacht in the world and the second largest yacht by volume of any type, after Fulk Al Salamah.

REV Ocean is the flagship of Norwegian billionaire businessman Kjell Inge Røkke's REV Ocean initiative. In an interview with the Norwegian newspaper Aftenposten (published 1 May 2017) Røkke said he planned to give away most of his fortune. As a further step in this plan he joined the Giving Pledge in 2017, and founded the REV Ocean initiative.

Led by former WWF Norway CEO Nina Jensen, REV Ocean is working to improve understanding of the ocean and foster concrete solutions through three initiatives: the world's largest research and expedition vessel (REV), the World Ocean Headquarters and an open, global data platform.[9]

She is purpose built for scientific charter and environmental research missions.[10]

Her TIER III hybrid propulsion allows a full-electric mode at eleven knots when the yacht collects samples. Her total operating range is 21,000 nautical miles
