Denmark-headquartered Cadeler has awarded its compatriot Semco Maritime a contract for vessel modifications to upgrade the main crane capacity on Cadeler’s two O-class wind farm installation vessels (WFIV).
Semco Maritime has previously fitted new and extended crane booms on the two WFIVs, Wind Orca and Wind Osprey .
The scope of work comprises planning and supplier coordination, fabrication and installation of a new boom rest, reinforcement of the crane pedestal, and various electrical and mechanical upgrades during the installation of new improved cranes supplied by GustoMSC.
Fabrication of an estimated 300 tonnes of steel structures will be initiated in early 2023 with planned installation on both vessels in the Port of Rotterdam from late 2023 and over a five-month period.
Cadeler contracted NOV to upgrade Wind Orca with a new and improved crane in December 2020. A year later, the company decided to do the same on Wind Osprey which will make the two vessels ready for the next generation of offshore wind turbines, according to Cadeler.
According to AIS data, Wind Orca is currently in the North Sea. The vessel was installing wind turbines at the 1.1 GW Seagreen offshore wind farm, which is being built 27 kilometres off the Angus coast in Scotland.
On the other hand, Wind Osprey is in the Dutch North Sea, according to AIS data. The jack-up was installing Siemens Gamesa 11 MW wind turbines at the 1.5 GW Hollandse Kust Zuid offshore wind farm.
