Data acquisition took place using the survey vessel MV ‘Barinthus’, during the period 21st to 23rd November 2007. High-resolution side scan sonar, swath multi-beam and single beam bathymetry data were acquired along three parallel survey lines, which were run at 25m centres, in order to accurately map the seabed along the cable route. For the scour monitoring survey within the development area, survey lines were run at 25m offsets from the turbine positions, in order to provide detailed information around the turbine/seabed interface. The primary objective of each of the surveys was to map bathymetry and seabed features, including any cable exposures, along the cable route. Additional survey lines, run across the faces of the selected turbines, were carried out to provide detailed scour assessments.

This provided a safe and convenient port of operation, with transit time to the development site being approximately 40 minutes, dependant upon the prevailing weather and sea conditions. MV ’Barinthus’ is a 13-metre fast workboat of glass fibre construction, which carries Category 2 certification (60 miles from a safe haven) under the current MCA Code of Practice for Small Workboats and Pilot Boats. A 12-hour operational day is normally adopted aboard the vessel in the interests of Health & Safety. A pre-survey Health & Safety meeting was held onboard MV ’Barinthus’ and attended by all members of the survey crew. Details of this meeting are presented in Appendix 6 to this report. All site staff had previously undertaken the Vestas safety induction course. A vessel offset diagram, showing navigation antenna position relative to the various sensors and towing points, is presented on the vessel track chart and in Appendix 3 to this report.
