The CSOVs are designed by Salt Ship Design and  will be built at Astilleros Gondán, Spain.

The 88.3-metre vessels will serve as mother ships for wind turbine technicians as they perform commissioning and maintenance work on offshore wind turbines. Cabins and common areas can accommodate up to 97 technicians and 23 marine crew, 120 persons in total. Anti-heeling and roll reduction systems will provide a very stable working platform, and the motion-compensated gangway system with an adjustable pedestal will ensure safe and efficient connections to the turbines, Østensjø Rederi announced in a statement.

“Significant growth is expected in the offshore wind market over the next decades, and we are confident these CSOVs will be the optimal and preferred tool for our clients, Østensjø Rederi has been working in the offshore wind market since 2016, and with the delivery of our first two service operation vessels (SOV) in 2018, the company has established itself as a major player in this market. In addition to our existing vessels, both on long term contracts with Ørsted, the four newbuildings will further strengthen our market position in offshore wind,”  stated Kenneth Walland, CEO of Østensjø Rederi.

“We are proud to present these low-emission vessels to the market. For Østensjø Rederi it is important to continuously push the development of environmentally friendly technologies. We firmly believe our new CSOVs will be the first zero emission vessels in this market,” he added.
