Airbus Helicopters is to provide the on-board helicopter for the REV Ocean research and expedition vessel – the world’s largest superyacht. The research expedition vessel, which is 600ft (183m) long, is the flagship of Norwegian businessman and philanthropist Kjell Inge Røkke’s not-for-profit oceanic research foundation, REV Ocean. Launched in 2019 and due for certification early in 2020, the new Airbus ACH145 has a bearingless five-blade rotor replacing the existing hingeless four-blade rotor, and provides 150kg additional useful load-carrying capability. As well as the ACH145, the vessel is equipped with scientific trawls, sonar systems, laboratories, moonpool, unmanned aerial vehicle, a remotely operated submarine with 6000 meters depth capacity, and advanced communication equipment. It has a crew of up to 35 and can carry 60 scientists. The yacht, designed by Espen Oeino, has arrived in Norway from the VARD Tulcea shipyard in Romania and will accept the helicopter on board when the aircraft is delivered in 2021.
