## Summary

The procurement process for the Subsea Soundscape (S3) program initiated by Celtic Sea Power Limited, a sub-central government public authority based in Hayle, United Kingdom, has gone through a tender and cancellation phase. The procurement, aimed at acquiring state-of-the-art broadband acoustic recorders and ancillary mooring units for deployment across the Celtic Sea, had an initial tender period ending on 31st March 2025, with final evaluation and termination on 7th April 2025. Despite thorough evaluation, the contract was not awarded due to bidders not meeting technical requirements and concerns over interoperability, leading to the procurement's termination on the said date.

This cancelled tender indicates potential opportunities for businesses specialising in marine technology and environmental sampling equipment to closely examine and prepare for future tenders. Suppliers providing integrated and advanced solutions for acoustic monitoring, fish tag detection, hydrophone recordings, and CTD environmental sensors with robust technical and operational capabilities could gain an advantage. SMEs with expertise in precision underwater equipment, data collection, and marine environmental services would be particularly well-suited to compete in the renewed or similar procurement processes, potentially enhancing their business growth in the marine renewables sector.

## Notice

The purpose of this Procurement is to procure for at-sea mooring units, equipped with state-of-the-art broadband acoustic recorders, pop-up acoustic retrieval systems and tag detection capabilities, and delivered to a workshop in Pembrokeshire, Wales, that will be deployed with CTD environmental sampling at service intervals to maximise data capture. S3 will deploy up to 21 remote systems across the Celtic Sea, each consisting of an acoustic release, a fish tag detector, a hydrophone, and a cetacean click-train logger. Where feasible, preference will be given to integrated solutions that combine multiple components-such as fish tag detection and acoustic release-into a single unit to enhance efficiency and deployment simplicity. The total budget of the Contract is PS303,000
