TGS is scheduled to start geophysical survey work across the Dogger Bank South (DBS) offshore wind farm sites in the UK on 27 March.
According to a Notice to Mariners issued by the DBS project, the Norway-based energy data and intelligence company will be using the seismic vessel Ramform Vanguard , supported by the guard/scout vessel MV Karelle , for the work. The survey campaign will be taking place until the end of May.
The 3D UUHRS geophysical survey involves data collection using both towed and onboard equipment, and will be performed across the project’s three sites: Dogger Bank South East (DBSE), Dogger Bank South West (DBSW), and Dogger Bank South Artificial Nesting Structures (ANS).
TGS announced in January that it secured a contract for offshore wind site characterisation on the UK continental shelf, for which it would use the Ramform Vanguard vessel, starting in the first quarter of this year. The company noted that the contract was with a repeat client but did not disclose any details.
Located over 100 kilometres off the northeastern coast of England, the Dogger Bank South project is owned by RWE (51 per cent) and Masdar (49 per cent), with RWE leading the project’s development, construction, and operation.
DBS is split across two sites, DBS East and DBS West, each with a capacity of 1.5 GW and spanning 500 square kilometres.
RWE and Masdar submitted a Development Consent Order (DCO) application with an Environmental Statement on 12 June 2024. On 17 December 2024, the Examining Authority issued a letter outlining a revised draft timetable for a six-month examination process, which started in mid-January 2025.
