Overview

Cefas has awarded a core contract and two call-off contracts for hydrographic expertise services to support marine environmental monitoring programmes for Sizewell C and Hinkley Point C nuclear power stations. The work involves technical review and quality assurance of nearshore hydrographic survey data, including bathymetric multibeam echosounder surveys examining geomorphological change, seabed change in dredging areas, and scour around infrastructure, with surveys expected to be at least quarterly throughout 2026. HR Wallingford Limited was awarded the core contract valued at £100,000, while Hydenlyne Limited and Metoc Ltd (trading as Intertek Metoc) were awarded call-off contracts to be used only when the core contractor cannot provide services.
