The Use of VHR 2D and 3D Sub Surface Data for Shallow Boulder Detection and Detailed Stratigraphical Mapping for Renewable Energy Developments
Currently there are not many options on the market for multi channel Ultra High Resolution (UHRS) As a result of this Gardline, in collaboration with Applied Acoustics, have been working on a new streamer system and bespoke source to go with it. The newly developed recording system and streamer is called uSeis, and consist of 1m group interval mini streamers. When designing and building the equipment, there were a series of objectives. Firstly, the idea was to develop a tool to provide cost effective ultra high resolution sub seabed seismic data to detect high reflectivity targets (for example boulders) Secondly the system needed to have a penetration capability of up to 75m. Thirdly a depth of burial measurement accuracy of less than 0.3m was required, and lastly the system should be capable of a 16m swath with a resolution capable of the detection of objects <1m in size. The applications of the system include geohazard boulder detection in shallow soils and the development of geomodels in Offshore Windfarms and Oil and Gas developments.
