Cadeler has signed two contracts with Orsted for the Hornsea 3 offshore wind farm in the UK.
The signatures took place today at a live signing ceremony at the WindEurope Exhibition in Bella Centre Copenhagen.
Together the two contracts constitute a very large contract award.
The first contract is for the transportation and installation (T&I) of all monopile type foundations on the project.
The project is expected to begin in Q1 2026 and finish by the end of the year.
The two companies signed the reservation agreement for this project back in August 2022.
The second contract is for the installation of around half of the wind turbines required, which will start around Q4 2026 and is expected to finish in 2027.
Cadeler will make use of one of its two newbuild X-class vessels.
With more than 500 foundations installed, Cadeler will, for the first time, be in charge of the whole T&I foundations scope and become a full-service provider in the offshore foundation business.
This also means Cadeler will be fully accountable for delivering the end product including a defect notification period after the installation is completed.
For this project alone, Cadeler expects to employ 25-30 office personnel and 30-35 specialist offshore technicians.
Furthermore, Cadeler has ordered two specialised F-class jack-up vessels specifically designed to excel in the T&I of the future generation of XXL monopile foundations such as the ones used in this Hornsea 3 project.
Patrick Harnett, Ørsted’s Vice President for Execution Programmes, said: “Hornsea 3 will represent another significant step forward for the offshore wind industry in terms of size and scale.
“To execute a project of this nature requires meticulous planning and skill, therefore close collaboration and strong relationships with our partners is key to success.
“We look forward to working alongside Cadeler when offshore construction begins to ensure the safe and high-quality delivery of the project.”
The Hornsea 3 wind farm, subject to Ørsted taking a Final Investment Decision on the project, will generate at least 2.85GW of renewable energy.
This new wind farm will be located in the North Sea, off the east coast of the UK, spreading across an area of 696 sq km.
