Finish line for Race Bank array cables

DeepOceanDeepOcean has confirmed that inter array cable installation and trenching operations have been completed at DONG Energy’s Race Bank offshore wind farm.

Further to the installation of 91 cables, totalling 106km, the scope also included route engineering, pre-lay grapnel runs, and cable protection system installation. Work kicked off in August 2016 and was completed across two phases.

Multiple vessels were mobilised during the works, including the Edda Freya and the CS Recorder which were utilised to install the cables. The Volantis  was used to deploy and operate the companys T2 and UT1 trenching systems whilst the Deep Helder was mobilised to carry out post trench survey works.

Siemens is currently installing and commissioning a total of 91 SWT-6.0-154 turbines at Race Bank and plans to complete the work before end of the year. Turbine installation is being carried out by A2SEAs SEA INSTALLER which is being supported by walk-to-work construction support vessel Acta Orion.

Construction is being managed from DONG Energys construction base in the Grimsby Fish Docks. Last year, the company announced plans for a multi-million investment in Grimsby to create an operations and maintenance hub to serve Race Bank as it enters operation.

Each of the projects turbines have a 6MW capacity and stand at 177m tall. The array will cover an area of approximately 75km2. The project is scheduled to be fully commissioned by the summer of 2018 with a capacity of 573.3MW it is anticipated to meet the energy demands of 400,000 UK homes.
