Shipbuilder Vard Holdings has secured a contract for the design and construction of a diesel-electric research expedition vessel (REV) for Rosellinis Four-10, a company owned by Norwegian industrialist Kjell Inge Røkke. Developed in collaboration with the customer and designer Espen Øino, the REV will feature an energy recovery rudder system, medium-speed engines, a direct-drive diesel-electric propulsion system with battery package, and an exhaust cleaning system. The vessel will also employ Vards SeaQ Green Pilot, a data-driven maritime energy management and operational performance system that provides advice on the ships performance and fuel consumption. The hull will be built at Vard Tulcea in Romania, and towed to Vard Brattvaag in Norway for outfitting. After delivery in Norway, the vessel will return to Romania for fairing, deck laying and finalisation of the accommodation area. It is expected to enter service in 2020. The 182m-long vessel, which will be the longest one ever designed and built by Vard, will feature equipment for monitoring and surveying marine areas, currents, the seabed, fish, animals and plant life in all of the worlds oceans. The vessels research and expedition area will feature laboratories, an auditorium, a hangar for a remotely operated vehicle and an autonomous underwater vehicle with direct access to the vessels moonpool, and a multifunctional cargo deck. It will be suitable for charter to private individuals, companies and institutions. The total accommodation capacity is for 90 persons, including a maximum of 36 guests on board. Rosellinis Four-10s Kjell Inge Røkke said, The REV 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.
