## Summary

The procurement process initiated by Celtic Sea Power Limited, a public undertaking based in Hayle, United Kingdom, focuses on acquiring submerged soundscape equipment, specifically CTD sensors and various underwater devices. The procurement falls under the category of laboratory, optical, and precision equipment, excluding glasses, and follows a direct award method due to an earlier failed open procurement procedure. The procurement stage is complete, but the contract is pending award, with a transparency notice published on the 22nd of April, 2025. This contract, valued at GBP 81,800, is intended to be awarded to R.S. AQUA LIMITED, located in Port Solent, United Kingdom. The contract period is set to start on the 1st of May, 2025, and conclude on the 31st of July, 2025.

This tender offers significant business growth opportunities, particularly for small and medium-sized enterprises (SMEs) experienced in providing laboratory and precision equipment. Companies specialising in the manufacturing or supply of underwater tracking and monitoring technology might find this procurement process particularly advantageous, as it demands expertise in interoperable systems. The direct award procurement method allows for a faster purchase decision, thereby offering interested businesses a relatively swift entry into a potentially lucrative collaboration with a public sector authority in the marine research and technology sector.

## Notice

Following an Open Procurement Procedure and on conclusion of the evaluation of all received tenders, the contracting authority was unable to award the contract due to the fact that none of the bidders met the technical requirements set out in the ITT and due to concerns re: interoperability there was no alternative but to terminate the procurement. Celtic Sea Power therefore intend to move to Direct Award
