This project was undertaken in 4 separate parts comprising: Survey 1 – Crossing and Proximity Agreement Survey (CPA) for WDS01; Survey 2a – Consent survey at WDS01 covering a selection of 6 turbines, associated array cables, the offshore sub‐station (OS) and export routes; Survey 2b – CPA for several crossings at WDS01; and Survey 3 – An Asset Integrity Survey (AIS) undertaken at Walney 1 and 2 offshore windfarms (WOW01 and WOW02). This series details the results of the survey of the export cable. Once published, there will be no limitations on public access.

In some instances, this compliance will not be feasible. True series A RESON SeaBat 7125 multibeam echo sounder was used to collect bathymetry data within the survey area. Within the transducer mounting a Sound Velocity sensor was fitted to provide realtime SV values. The system was interfaced with the Applanix PosMV system to provide timing and motion data to the collected bathymetry data. The MBES and peripheral sensors were interfaced to QPS QINSy, which stored and visualised the data during acquisition. The Simrad EA400 Single beam echo sounder was utilised as a quality check on the absolute values of the MBES data. This data was also interfaced to QPS QINSy, which recorded and visualised the data. The multibeam system performed as expected during acquisition, providing generally high quality data collection throughout the survey area, though cavitation around the hulls caused by marginal weather lead to data dropouts, particularly when heading into the weather. Data was continually monitored during acquisition by the online ABP Marine Environmental Research Ltd 02380711840 enquiries@abpmer.co.uk pointOfContact EPSG Geodetic Parameter Registry 2024-02-24 revision ETRS89
