CEFAS22-25 BEEMS Hinkley 2022 bathymetric survey

Descriptions

The BEEMS (British Energy Estuarine and Marine Studies) programme is funded by NIB GenCo (EDF Energy). Through this programme, Cefas provide authoritative scientific information on the marine and transitional waters in the vicinity of potential new build nuclear power stations and require a competent Contractor to deliver the element described below. Bathymetric surveys in the Severn Estuary are required to be completed during the construction phase of the Hinkley Point C (HPC) build programme. A total of six surveys may be required in 2022 / 2023; three of which are confirmed, while the other three depend on the outcomes of technical and regulatory decisions. Two of the confirmed surveys will cover the Portishead dredge disposal area and King Road approaches to meet a licence requirement to undertake bathymetric surveys at defined intervals following the disposal of dredged material in the disposal area. One to three surveys are required to meet a licence requirement to undertake bathymetric surveys around newly installed subsea cooling water intake and outfall infrastructure, seaward of the HPC construction site. There is a confirmed required for one survey of this area, and a potential further requirement for two additional surveys.
