Hornsea Two Offshore Construction Begins

Hornsea Two Offshore Construction Begins

The jacket foundation for the offshore substation at the Hornsea Two offshore wind project in the UK has been installed.


The installation of the 4,800-tonne jacket marks the start of the project’s offshore construction.

Six weeks ago, 10,000 tonnes of steel framework for the pin piles, reactor compensation and offshore substation jackets sailed from Batam, Indonesia, towards the wind farm site in the UK.

Sembcorp Marine is in charge of the construction of the offshore substation and RCS at its yard facilities in Singapore.

”We’re delighted to announce that we’ve now officially commenced our offshore construction for Hornsea Two with the installation of our offshore substation and reactor compensation jackets,” said Patrick Harnett, Ørsted Senior Programme Director for Hornsea Two.

“Through a remarkable feat of engineering together with our partners, we’ve overcome COVID challenges and are on track for fabricating the world’s largest AC offshore substation, which will be supported by this gigantic steel structure.”

Hornsea Two will comprise 165 Siemens Gamesa 8 MW turbines located some 89km north-east of Grimsby. The 1.4 GW project is scheduled to be commissioned in 2022.
