Engineering, installation and maintenance services firm The Correll Group says two of its five divisions recently secured contracts for projects based in Denmark and England.
The cable installation and power services division has been contracted by Asso.subsea to deliver the offshore pull-ins and termination and testing of 66 kV export and inter-array submarine cables for Denmark’s Vesterhav Nord and Syd wind farms. The two offshore wind farms consist of four export and 37 inter-array cables, for a total of more than 43 miles.
Located about six miles and four miles offshore, respectively, Vesterhav Syd and Vesterhav Nord will comprise a total of 41 Siemens Gamesa 8.4 MW turbines with a combined capacity of 344.4 MW.
When fully commissioned, the wind farms are expected to generate 1.57 TWh of power a year, which is expected to meet the energy needs of 380,000 households in Denmark.
“This contract firmly establishes Correll as a leading service provider to the offshore renewable sector,” Sam Dowey, managing director at Correll.
Nearby in England, the Correll Group’s electrical engineering division has been awarded a contract by Deme Offshore NL B.V. to complete the 66 kV inter-array cable termination and testing on 95 wind turbines and the offshore substation platform on the first phase of Dogger Bank Wind Farm, including the installation of a cable-monitoring system.
The offshore wind farm is being built in three 1.2 GW phases; Dogger Bank A (95 wind turbines), Dogger Bank B (95 wind turbines) and Dogger Bank C (87 wind turbines). Under construction in the North Sea more than 80 miles off the northeast coast of England, the 3.6 GW project will be the world’s largest offshore wind farm when completed in 2026.
Offshore construction on Dogger Bank A began in spring 2022. First power is expected in summer 2023 and summer 2024 for Dogger Bank A and B, respectively. Turbine installation for Dogger Bank C will begin in 2025.
Dogger Bank Wind Farm will use some of the world’s largest and most powerful offshore wind turbines in operation today: GE’s Haliade-X. As the first order for the Haliade-X 13 MW and 14 MW machines, Dogger Bank will be the first time the turbines are installed in the world.
“Correll have extensive experience in working on some of the most significant offshore wind farms around the world,” says Dowey, “so to secure this work on what will be the world’s largest offshore wind farm is a glowing testament to the entire team’s hard work and tenacity.”
