Nearshore Export Cable Route Survey

The proposed wind farm is located in the outer Firth of Tay, approximately 15 - 22km east off the Angus coastline. 

The objectives of the export cable route survey were to:

  • Determine water depths reduced to LAT;
  • Identify seabed features and obstructions;
  • Determine the seabed sediments and sub-seabed lithology, topographical and geological features that could impact on the satisfactory installation and trenching of the cable such as wrecks, boulders, exposed bedrock, seabed gas seepage, pockmarks, adverse gradients, sand waves, slumping or channelling;
  • Determine the physical and engineering properties of the seabed sediments;
  • Collect data to assist assessment of archaeological features;
  • Collect geotechnical samples including vibrocores (VC) and cone penetrometer tests (CPT), to identify and classify the material in order to further aid cable burial assessment studies.
