Geo-4D are supporting an offshore transmission owner (OFTO) with the management of several offshore wind farm export cables.
Geo-4D manages all historic survey data that has been transferred to the OFTO, and has generated a comprehensive 3D ground model and probabilistic risk assessment along the cable routes. The ground models include all bathymetric, sub-bottom geophysical and geotechnical data, and enables efficient, accurate management of cable protection and burial.
Each year Geo-4D prepare the scopes of work and contractual documentation for the proposed marine geophysical and depth of burial survey campaigns. Geo-4D also provided client representation during survey operations, with follow up data interpretation and ground model update.
Geo-4D has liaised with stakeholders, including Marine Management Organisation, The Crown Estate and Port Authorities, and provided GIS deliverables as required.
