## Summary

The public procurement process was initiated by the National Oceanography Centre, a sub-central government authority based in Southampton, United Kingdom. The tender, titled "Specialist OEM Maintenance for RDI ADCP Instrumentation," pertains to the services industry category, specifically focusing on repair and maintenance services related to marine equipment. This process is at the contract award stage, having been completed with an effective date of 2nd February 2026, and will run until 1st February 2027. The procurement was conducted using a direct method below the threshold, without competition, due to the specialised nature of the work and the proprietary rights involved.

This tender provides significant opportunities for businesses engaged in the maintenance and repair of specialised marine instrumentation. Companies with expertise in the repair of Teledyne RDI Acoustic Doppler Current Profilers, or those with the capability to become authorised service partners, would be well-positioned to compete in similar tenders. However, this contract was specifically awarded to Saderet Limited, as they are the sole authorised UK distributor and service partner for Teledyne RDI, underscoring the importance of niche specialisation and strategic partnerships in securing such contracts.

## Notice

This procurement covered the repair and refurbishment of Teledyne RDI Acoustic Doppler Current Profilers (ADCPs), valued at $122,780 (ex VAT). The works were carried out by Saderet, the sole authorised UK distributor and service partner for Teledyne RDI, as only the OEM possessed the proprietary components, calibration systems, diagnostic tools, firmware, and intellectual-property rights required for legitimate repairs.
