## Summary

The Centre for Environment, Fisheries and Aquaculture Science (Cefas) has concluded a procurement process titled "CEFAS24-07 Contract for the provision to provide subtidal Sabellaria surveys at Hinkley Point C" in the services category for survey services. The subtidal monitoring surveys are part of the Hinkley Point C (HPC) Nuclear New Build (NNB) project, focusing on environmental monitoring requirements. The contract, awarded to Ocean Ecology Limited, includes detailed surveys using advanced sonar technology to measure the spatial extent and condition of the subtidal biogenic reefs present on the seabed at Hinkley Point. The procurement method used was an open procedure, and the award was signed on 2nd December 2024, with surveys scheduled in Autumn/Winter 2024/25 and Spring 2025 across specified areas of interest.

This tender opens up significant opportunities for businesses specialising in marine environmental surveys, especially those with expertise in high-resolution sonar data collection and seabed assessments. Companies with access to the required 'Sound Metrics ARIS Explorer 3000' equipment or the capability to hire it are well-suited to benefit from such projects. The contract, valued at approximately £145,558 GBP, highlights the importance of providing quality and consistent data, offering growth potential for firms in the marine survey industry. Moreover, businesses focusing on environmental protection and regulatory compliance in marine settings can leverage this contract to bolster their service offerings and market presence.

## Notice

Cefas require a supplier to conduct subtidal monitoring surveys for the Hinkley Point C (HPC) Nuclear New Build (NNB) project to meet regulatory environmental monitoring requirements.

### Lot Information

Lot 1

The Hinkley BEEMS (British EDF Estuarine and Marine Studies) programme is funded by New Nuclear Build Generation Company (HPC) Ltd. 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 supplier to deliver the following;

Cefas require a supplier to conduct subtidal monitoring surveys for the Hinkley Point C (HPC) Nuclear New Build (NNB) project to meet regulatory environmental monitoring requirements. At HPC, the Sabellaria spp. monitoring programme focuses on mapping and assessing the condition (i.e. reefiness) of the subtidal biogenic reefs present on the seabed at Hinkley Point.

The objective of the proposed surveys is to measure the spatial extent of the Sabellaria spp. by collecting high-resolution Side Scan Sonar (SSS) data of the area of interest and to ground-truth an area of the seabed with an Adaptive Resolution Imaging Sonar (ARIS) camera (Sound Metrics ARIS Explorer 3000) and RT3 rotator to confirm the seabed type and the presence or absence of Sabellaria spp. tube aggregations.

A survey is required in Autumn/Winter for Financial Year 24/25 (November 2024 - February 2025) and a second survey in Spring (April/May) 2025. The specified 'Sound Metrics ARIS Explorer 3000' is required to ensure quality and data consistency with the previous survey, and therefore it is a requirement for the supplier to either own or be able to hire, the equipment for the survey. The Autumn/Winter survey extent comprises an area of 9.7 km2, with the Spring survey extent 5.3 km2, extending to approximately 4.5 km offshore from Hinkley Point.
