## Summary

The National Grid Electricity Transmission PLC has awarded a contract for the project titled "Sea Link- Targeted Marine Surveys" in the services category. The contract involves targeted marine surveys between Aldeburgh and Pegwell Bay, covering geophysical, geotechnical, and environmental sampling. The procurement method used was a selective negotiated procedure with a prior call for competition. The award was active as of 13th October 2023.

This tender presents opportunities for businesses involved in marine survey services to participate in a detailed RFP process for a Marine Seabed Survey contract. Companies with expertise in geophysical and environmental sampling, as well as a track record in delivering accurate survey reports, are well-suited to compete. The project has specific deadlines, with a start date for the survey targeted before June 2023 and completion by October 2023.

## Notice

The general requirement is for targeted marine surveys of 5 specific areas (see map) between Aldeburgh (East Suffolk) and Pegwell Bay (Kent), to supplement a survey of the whole route undertaken in 2021, to inform of seabed morphology and shallow sediment structure, and to provide benthic characterisation and habitat maps. The PQQ process is to establish market capability to carry out the required works within the time period indicated. It is the Client's intent to follow up the PQQ responses with a tendering process with a view to award a Marine Seabed Survey contract based on a detailed RFP process. The survey scope of work covers geophysical, geotechnical and environmental sampling. In addition to the 5 survey areas, the scope of work may potentially include an additional offshoot survey of the main route in the near future.
