Ecosse Wraps Up 2nd Seabed Clearance on Race Bank OWF
Ecosse Subsea Systems (ESS) has completed second seabed clearance project on behalf of DONG Energy on the Race Bank offshore wind farm.
ESS cleared more than 3000 boulders at the wind farm site, located off the Norfolk and Lincolnshire coast.
Race Bank will consist of 91 turbines of 6MW each and generate enough electricity to power more than 500,000 homes.
ESS teams mobilized several vessels including Siem Topaz and Siem Sapphire for the work.
The company deployed the latest version of its SCAR 2 seabed system, while an ROV grab was used to remove boulders and debris.
The boulder clearing took place across the export corridor, array cable routes and turbine locations, with 30-meter plus clearance corridors created using multi-pass capability, the company explained.
DONG Energy senior project manager, Luke Bridgman, said: “Ecosse has done an excellent job preparing the seabed for our arrays, export cable and foundation installation.”
