Gondan Shipbuilders has started the construction of two commissioning service operation vessels (CSOVs) for Østensjø Rederi.
In October 2019, Østensjø Rederi signed a letter of intent for the construction of four CSOVs to meet the increasing demand in the offshore wind market.
According to the latest information from the Norwegian company, that order is now for two CSOVs and two service operations vessels (SOVs).
Designed by Salt Ship Design, the 88.3-meter long commissioning service operation vessels can accommodate up to 120 persons.
They are set to be delivered in 2022 and will serve as mother ships for turbine technicians while performing commissioning and maintenance work.
The first delivered CSOV will service the BARD 1 offshore wind farm in Germany.
Østensjø Rederi stated that the CSOVs are the first to incorporate technology that will allow zero-emission operation in the future due to the use of hydrogen, as well as the first with Blue Drive + C Star diesel-electric propulsion which reduces fuel consumption.
