DeepOcean is pleased to confirm that all 91 Inter Array Cables have been safely installed and that the base scope trenching operations are complete at DONG Energy’s Race Bank Offshore Windfarm site. Once fully operational, Race Bank will have a capacity of 573MW which will provide sufficient green energy to power over half a million UK homes from the 91no. 6MW turbines off the Norfolk coast.
This project, which is considered to be DONG Energy’s most complex to date, is located at a challenging worksite with strong currents, shallow waters, widely varied seabed soils, and of course, consistently strong winds. DeepOcean with an extensive track record in subsea power cable installations on critical infrastructure projects, was able to successfully complete the installation and burial of the 91 cables with an approximate overall length of 106km. The scope also included route engineering, pre-lay grapnel runs, and cable protection system installation.
Some key project highlights included:
In addition to the tracked T2 Trencher, DeepOcean also buried cables using the highly capable free flying UT1 Trencher, also operated from the Volantis.
The success with the above operations confirms that DeepOcean remains particularly suited to challenging projects in tough environmental conditions.
