G-tec

G-TEC completed a seabed (geophysical) survey in the Doordewind Wind Farm Zone (DDWWFZ) under a contract signed with the Netherlands Enterprise Agency (RVO) in 2024. The DDWWFZ is planned to accommodate 4 GW of offshore wind capacity split across two 2 GW sites, Doordewind I and Doordewind II, and the survey outputs were intended to support the government’s preparations for upcoming permit tenders. The offshore survey work was carried out using G-TEC’s survey vessels Mainport GEO and Karina. G-TEC reported that it acquired, processed, and delivered a package of geophysical data including multibeam echosounder (MBES), side-scan sonar (SSS), sub-bottom profiler (SBP), and magnetometry (MAG). The company stated that the combined dataset enabled a clearer geological understanding of the surveyed part of the wind farm zone. RVO described the deliverables as a critical input to the Integrated Ground Model for the Doordewind zone. The seabed data was expected to be used to plan forthcoming geotechnical investigations and to support the design and installation planning for offshore wind infrastructure (including foundations and inter-array cables) by future tender participants. This engagement was therefore a development-stage site characterisation contract.
