Utilizing methodologies such as single-beam bathymetric, side scan sonar, seismic, and topographic surveys, the survey covered a 10 square kilometre area and included high-precision GPS and total-station equipment. The findings revealed a predominantly flat and featureless seabed with minor sand ripples, localised debris, notable sub-seabed features (including a buried channel and sediment thickness variations), and minimal hazards except minor obstructions and archaeological features. The study concluded these results provide essential baseline data for foundation design, future monitoring, and cable routing, and recommended that the data be used as a primary planning resource for wind farm construction, with all positions referenced to National Grid, ETRS89, and OSGB36 datums.

When a mosaic was produced a lot of the detail of the area was lost due to the size of the data set and limitations in plotting. Therefore a seabed classification drawing was produced based on this data. Close inspection of each digital file confirmed that the site area is a flat and featureless area of seabed which has some minor sand ripple activity to the eastern and western extremities near the two sand bank features.
