Geophysical and Shallow Sub-Surface Survey Services at the Port of Port Talbot

Associated British Ports intends to award a utilities services contract for the delivery of geophysical and sub-surface survey works around Port Talbot.

The scope of the Services includes geophysical, sub-surface, environmental and marine monitoring surveys that may be required to support project development around Port Talbot. The survey campaigns are split in to two phases, the initial contract award will encompass phase 1 (shallow sub-surface survey services).

ABP intends to enter into a further contract for the execution of phase 2, including but not limited to UXO and seismic surveys. ABP reserves the right to modify the contract after initial award, in accordance with s31, s74 and Schedule 8.

The Scope of Services is comprised of:

Phase 1: Firm Scope, surveys anticipated November - December 2026

Reconnaissance geophysical survey to collect the following data :

• High-resolution bathymetric data.
• Sidescan sonar seabed reflectivity.
• Sub-bottom profiler data to image the shallow sub-surface (<10 m).
• Opportunistic magnetometer survey data.

The survey area extent is ~60 km2 in water depth range ~25 to 35 m below LAT, located approximately 10-15km from the coastline.

Phase 2: Optional Scope 2027

UXO and seismic survey to collect the following data over a refined area and an optimised Cable Corridor:

• Single channel seismic data to image the sub-surface to approximately 30 m below seafloor.
• High-resolution bathymetric data.
• Magnetometer data for UXO assessment purposes.
