BW Group and Swire-backed shipowner Cadeler has revealed more work for its wind turbine installation vessels (WTIVs).

The Oslo-listed company said it has secured “yet another” preferred supplier agreement with an undisclosed client.

The contract covers the transport and installation of next generation wind turbines at a tentative value above €45m ($50m).

The installation project is set for execution by one of Cadeler’s O-class vessels, which at the time the term starts will feature a new and larger main crane.

More charter backlog has also been added in a deal with Danish energy supplier Vestas.

The “important strategic” contract involves work for the two O-class ships up until they are upgraded in the fourth quarter of 2023.

“The agreements ensure optimal utilisation of the Cadeler fleet before and after the crane upgrades,” the company said.

“Offshore wind activity continues to strengthen,” Cadeler added.

The 161-loa Wind Orca and Wind Osprey (both built 2012) have been active throughout 2021. Looking ahead, both vessels will continue to be busy installing WTGs in European waters, the company said.

Strong backlog

Chief executive Mikkel Gleerup added: “The contract with Vestas adds yet another important project to our strong order backlog and further highlights our close relationship with clients in the industry.”

The Wind Orca is soon scheduled to embark for the Seagreen Offshore Wind Farm project off the coast of Scotland to replace the Wind Osprey, which in turn will start working on the Hollandse Kust Zuid project.

After Seagreen is finalised, the Wind Orca will continue working on the new contract with Vestas.

The new cranes will give a lifting capacity of 1,600 tonnes at a radius of 40 metres, with the main hook at a height of 160 metres above the main deck.
