Offshore Site Preparation

As part of the Codling–Poolbeg 220 kV export system, seabed preparation and protection works are planned along the offshore cable routes from Codling Bank to Dublin Bay. Installation of the export cables will involve seabed preparatory works such as jetting, trenching or ploughing, burial to a minimum cover of about 1.4 m below seabed where feasible, and deployment of secondary protection (rock placement or concrete mattresses) in areas where target burial depth cannot be achieved, as set out in the project’s export cable burial and protection planning drawings.
