Investigations completed for Navitus Bay

Coastline Surveys has completed a geotechnical investigation of the seabed cable route at the proposed Navitus Bay offshore wind farm off the South coast of England.

The team has provided geotechnical expertise to examine the viability of the proposed cable route that will transport energy from the wind park to shore.

Utilising its own 24m survey vessel, MV Flatholm, along with its C-COREHP vibrocorer, Coastline Surveys successfully completed sampling at 22 locations along the planned route for the cable, which runs from the shoreline to approximately 12 miles offshore.

Coastline Survey’s C-COREHP unit has a real-time Penetrometer fitted to it, to monitor the rate of penetration during sampling. This was especially invaluable in areas of softer loose sediments as it allowed the geotechnical team to recover high quality samples with reduced disturbance.

Lab testing and reporting was completed at Coastline’s facility in Lowestoft. The geotechnical logs, soil descriptions and core photography provided to Navitus Bay were of sufficient quality and standard to assist with identification of archaeological features.
