TGS to Commence Geophysical Survey Work at Dogger Bank South Offshore Wind Farm Sites

Energy data and intelligence company TGS is set to kick off geophysical survey work at the Dogger Bank South (DBS) offshore wind farm sites in the UK on March 27, as per a Notice to Mariners issued by the DBS project. The survey will be conducted using the seismic vessel Ramform Vanguard, accompanied by the guard/scout vessel MV Karelle, and is scheduled to continue until the end of May.

The 3D UUHRS geophysical survey will involve data collection utilizing both towed and onboard equipment, covering the project’s three sites: Dogger Bank South East (DBSE), Dogger Bank South West (DBSW), and Dogger Bank South Artificial Nesting Structures (ANS).

In January, TGS announced securing a contract for offshore wind site characterization on the UK continental shelf, utilizing the Ramform Vanguard vessel, beginning in the first quarter of this year. While the client remains undisclosed, it is noted as a repeat customer.

Positioned over 100 kilometers off the northeastern coast of England, the Dogger Bank South project is a joint venture between RWE (51%) and Masdar (49%), with RWE leading the development, construction, and operation of the project.

DBS is divided into two sites, DBS East and DBS West, each boasting a capacity of 1.5 GW and spanning 500 square kilometers.

RWE and Masdar recently submitted a Development Consent Order (DCO) application with an Environmental Statement on June 12, 2024. The examination process, which commenced in mid-January 2025, follows a revised draft timetable outlined by the Examining Authority in a letter issued on December 17, 2024.
