We supply comprehensive packages to establish water depth and sediment / bedrock characteristics for Offshore Wind Farm and Marine Pipeline / Cable Route construction. Please refer to the techniques below for further details.
Seabed Profiling
- Digital echo sounder in conjunction with differential global positioning surveying used to carry out bathymetric surveys in both shallow marine, river and lake environments.
- Processing of data to produce bathymetry track plots and contour plots all to a specified datum.
Marine Geotechnical Investigations
- Boreholes and sampling carried out from floating platform or jack up barge.
- Geophysical sub-bottom profiling carried out using boomer or sparker array to determine thickness of sediment overlying rock.
- Geophysical side-scan sonar and magnetometer surveys to analyse sea bed cover and locate cables, pipes and wrecks.
Marine Pipeline Routes:
- Long linear corridors, as required for pipeline and cable routes lend themselves to geophysical surveying. Fast, efficient and repeatable results are achievable using marine geophysics.
- Sediment thickness, presence of gravel and location of rock can be mapped along a series of linear profiles.
- Surface and buried debris can be recorded by the use of electromagnetic and side scan sonar methods.
- All data can be presented as a series of scaled plates along the route of the proposed scheme.
