TGS commences Dogger Bank South seabed geophysical survey

Survey company TGS has commenced detailed seabed geophysical surveys for the eastern array of the proposed UK Dogger Bank South (DBS) offshore wind farms for RWE and Abu Dhabi Future Energy Company PJSC – Masdar.

"These site investigations will enhance understanding of the seabed conditions over 122 kilometres off the northeast coast of England," said TGS.

"TGS started the surveys in April, acquiring ultra-high resolution 3D (UHR3D) seismic data to assess the subsea terrain at turbine locations."

DBS consists of two offshore wind farms with a combined proposed capacity of 3GW. RWE leads both DBS projects, overseeing development, construction, and operations on behalf of partners RWE and Masdar.

At 3GW, these projects are the UK's most powerful offshore wind farms under development. They are currently advancing through the Nationally Significant Infrastructure Project (NSIP) planning process, with a consent decision anticipated by the end of the year.

If approved, and following a financial investment decision (FID), construction could commence in 2026/27, with first power generation expected to contribute to the UK Government’s target of 60GW of offshore wind by 2030, and full completion by 2031/32.
