## Summary

The National Oceanography Centre, a sub-central government public authority based in Southampton, United Kingdom, recently completed the procurement process for the "Provision of Acoustic Data Modems". This process was conducted under direct procurement, specified as below threshold without competition. The contract was awarded to SONARDYNE INTERNATIONAL LIMITED for the supply of two Sonardyne Modem 6 MF Directional Acoustic Modem Units.

The contract was signed on 3rd July 2026 and runs until 2nd October 2026, with a total gross amount of £49,850.88.

This procurement represents a significant opportunity for businesses specialising in hydrographic instruments and telemetry apparatus, particularly those capable of supplying advanced subsea communication technology.

Companies with capabilities in the design and manufacture of robust, high-performance communication devices for challenging underwater environments would find such tenders lucrative for business growth.
