Metadata: 2011, Gardline and Senergy, Beatrice, Export Cable Corridor Geophysical Survey
Abstract:
The geophysical survey of Beatrice Offshore Wind Farm Export Cable Corridor was undertaken by Gardline Geosurvey, commissioned by Senergy Survey & Geoengineering and carried out between 25th May and 15th June 2011. The purpose of the survey was to assist in the installation of the export cables from the Beatrice Offshore Wind Farm to the landfall situation on the southern shore of the Moray Firth, adjacent to Portgordon. The scope of the route survey was to obtain the following along the proposed corridors: - determine water depths reduced to LAT - identify seabed features and obstructions - determine the seabed sediments and sub-seabed lithology, topographical and geological features that could impact on the satisfactory installation and trenching of the cable such as wrecks, boulders, exposed bedrock, seabed gas seepage, pockmarks, adverse gradients, sand waves, slumping and channelling - determine the physical and engineering properties of the seabed sediments The following route surveys were required: - Survey of the Beatrice Site Approach Zone - Survey of the Routes between the Beatrice Start Point (SP) and the 2 Landfall locations (Options A&B) The Beatrice Site Approach Zone polygon was surveyed in its entirety using single and multibeam echo sounders, sidescan sonar, sub-bottom profiler and magnetrometer with the primary survey lines running in an approximate northeast/southwest orientation. Survey line spacing was 100m. In addition, two secondary orthogonal lines were run. Due to the engineering requirements on the cable installation, the width of the cable route corridor surveyed was dependent on the water depth. The cable route centrelines were acquired first utilising single and multibeam echo sounders, sidescan sonar, sub-bottom profiler and magnetrometer. This was done in order to plan the required line spacing for the route corridor. The Gardline vessel MV Ivero surveyed to the 10m water depth contour along both Route Options A and B. The nearshore approaches within the 10m contour were acquired by the Titan Environmental Surveys Ltd vessel Tital Endeavour. Equipment used during survey - Single and multi-beam echo sounder, sidescan sonar, pinger, magnetometer, vibrocore and CPT equipment The proposed Beatrice Export Cable Routes A and B are 64.769km and 64.654km long respectively. The survey corridor width and number of survey lines varies according to water depth. Along the proposed route, water depths vary between 0.0m and 95.8m LAT. No infrastructure is present within the route corridor; however there is existing infrastructure within the vicinity of the route. The seabed was sampled by means of a vibrocorer and cone penetometer. These samples were used to assist interpretation of sonar and shallow geophysical data. Tidal elevations have been derived using post-processed GPS observations. The sounding datum specified for this project was LAT. A dual channel sidescan sonar system was used to scan the seabed to either side of the ship's track, to locate and identify seabed obstructions and to investigate seabed soil properties and boundaries. One moderate analogue seismic system was deployed to investigate and map shallow soil units. The seabed was sampled by means of a vibrocorer. These samples were used to assist interpretation of sonar and shallow geophysical data. The seabed was also sampled by means of a seabed penetometer.
