On the instructions of Robin Rigg Offshore Wind Limited, Osiris Projects were commissioned to undertake a pre-construction survey covering the proposed Robin Rigg Offshore Wind Farm development site and associated cable. A total of over 400 line km of geophysical data were collected during the survey, which was undertaken during the period 1st to 9th June 2007. High-resolution side scan sonar, swath multi-beam and single beam bathymetry and magnetometer data were acquired along all survey lines, which were run at 100m centres, with cross lines at 200m centres, in order to accurately map the entire seabed within the wind farm development area. For the proposed cable route, eight parallel survey lines were run using swath bathymetry and side scan sonar techniques, to provide full coverage of a 500m wide corridor. The primary objective of the survey was to map seabed features and bathymetry, both within the wind farm area and along the associated cable route.
