Ecosse Subsea Systems has completed a seabed clearance project for Dong Energy at the site of the 573MW Race bank offshore wind farm located off Norfolk and Lincolnshire.
The Scottish subsea technology specialist said it cleared more than 3000 boulders at the site using its Scar 2 seabed system.
Ecosse mobilised several vessels in two campaigns, including the Siem Topaz and Siem Sapphire, over approximately 175 shipping days.
The boulder clearing took place across the export corridor, array cable routes and turbine locations, with 30-metre plus clearance corridors created using multi-pass capability, the company said.
Ecosse commercial director Keith McDermott said: “We were working in some very difficult environmental conditions and with a variety of soil conditions and the Scar proved its worth on both counts.
“We are constantly reviewing Scar to introduce improvements which bring savings to the client and this latest version Scar 2 has a 15-metre wide capacity compared to earlier 10-metre models.”
Race Bank will consist of 91 6MW turbines.
