Energy services giant Petrofac has installed a gamma jacket weighing more than 10,000 tonnes for a North Sea wind farm.
Once completed, the BorWin3 project, which lies 80miles from the German coast, will power nearly a million homes.
Petrofac has installed the jacket in water depths of 40 metres, where it will now await the topside for connection.
The project will be operated by Dutch firm TenneT.
Petrofac project director Roberto Cecchini said: “The safe and timely installation of the jacket represents another meaningful step forward towards the successful delivery of the BorWin Gamma platform.
“This is the result of well-coordinated cooperation and a spirit of partnership and determination established among the numerous parties involved.
“As we progress with the current critical stages of the project, there are still challenges ahead so we will remain vigilant, with a continued focus on delivery to complete the platform in line with our objectives and to the satisfaction of TenneT.”
