BW Group-backed Cadeler has revealed two more huge wind farm charters as it moves to cover the whole transport and installation (T&I) chain for the first time.

The Oslo-listed Danish shipowner said it has clinched work from compatriot energy supplier Orsted for the Hornsea 3 project off the UK.

The deals together are worth between €500m ($551m) and €700m, Cadeler added without giving an exact figure.

The first contract to install turbine foundations will position the company in a completely new and strategic business area as a full-service T&I provider.

This begins at the start of 2026 and will take the rest of the year.

The second contract is for the installation of around half of the wind turbine generators (WTGs) needed at Hornsea.

This work will start just as the foundations are completed and is expected to finish in 2027.

Cadeler will make use of one of its two X-class installation newbuildings for the deals.

With more than 500 foundations installed, Cadeler is very experienced in the offshore foundations space.

“But this will be the first time the company will be in charge of the whole T&I foundations scope and become a full-service provider in the offshore foundation business,” the owner said.

Fully accountable

“This also means Cadeler will be fully accountable for delivering the end product including a defect notification period after the installation is completed,” it added.

Cadeler hopes this will be the first of many such full-service contracts.

As a result, it is adding staff.

For this project alone, Cadeler expects to employ 25 to 30 office personnel and 30 to 35 specialist offshore technicians.

And it has two specialised F-class jack-up installation ships on order.
