Dogger Bank (UK) Cable Route: OMM Completes Assessment

Offshore Marine Management (OMM) completes a feasibility study for Forewind’s planned North Sea wind energy development.

The study was undertaken to assess route feasibility options along one of the development’s 160km long export cable corridors. The scope of work required OMM to analyse survey data, establish a Burial Protection Index (BPI) and carry out a burial assessment to recommend cable burial depths along the route. This was used to advise on the potential need for corridor widening and cable protection measures, including advising on appropriate techniques for cable burial and protection along the route.

OMM used its in-house Esri GIS facilities to assess the data provided for geology, obstructions and boulders to enable Forewind to be more informed on the potential quantities and costs of cable protection.

Oliver Taylor, Survey Manager at OMM, commented: “This was another successful delivery of a feasibility study, which will aid Forewind in the consenting process for one of its development stages of Dogger Bank. OMM continue to offer high quality services to Forewind, which include GIS-based data assessments, feasibility studies and other cable engineering studies”.
 
The Dogger Bank Zone is in the North Sea, located between 125 and 290 kilometres off the east coast of Yorkshire. It extends over approximately 8660 km2 with its outer limit aligned to UK continental shelf limit as defined by the UK Hydrographic Office.  Dogger Bank is the largest of the Round 3 zones but with water depths ranging from 18 to 63 metres, it is also one of the shallowest. It has the potential for approximately 4GW development capacity in less than 30m water depths and 8GW in less than 35m water depths
