2007, Osiris Projects, Barrow Offshore Wind Farm, Cable Route Inspection and Scour Monitoring Survey

Description

On the instructions of Barrow Offshore Wind Limited, Osiris Projects were commissioned to undertake an inspection survey covering the proposed Barrow Offshore Wind Farm cable route, in conjunction with scour monitoring surveys at a dataset of selected turbine locations within the main development area. 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.
