## Summary

The National Oceanography Centre, based in Southampton, United Kingdom, is proceeding with a contract amendment related to the procurement of a Low-Frequency Acoustic Doppler Current Profiler, initially awarded on 10th February 2026. The contract pertains to the provision of oceanographic instruments essential for the RAPID array offshore of the Bahamas, underlining a strategic upgrade of ageing equipment. The procurement falls under the category of surveying, hydrographic, oceanographic, and hydrological instruments. The contract notice concerning this amendment was published on 25th February 2026 with the amended contractual commencement set for 2nd March 2026 valued at £200,667 GBP gross with a duration until 2nd March 2027. The procurement method employed was limited competition, highlighting a below-threshold opportunity for suppliers.

This tender offers significant growth opportunities for businesses specialising in oceanographic instrumentation and hydrological surveying solutions, particularly those capable of providing advanced profiling capabilities and long-term deployment readiness. Such tenders are ideal for small and medium-sized enterprises in the scientific equipment manufacturing and supply sector to expand their market presence and cater to emerging technological requirements. Companies with expertise in integrating instrumentation within specific configurations, such as syntactic buoyancy or seabed-mounted setups, will find this contract particularly suitable, presenting a chance to collaborate closely with a public authority focusing on ocean sciences and technology enhancements.

## Notice

The National Oceanography Centre (NOC) has awarded a contract for the provision of a low-frequency Acoustic Doppler Current Profiler (ADCP) for deployment on the RAPID array offshore of the Bahamas. The procurement forms part of a planned refresh of ageing instrumentation and provides enhanced profiling capability to improve data quality and enable comparison of full-depth current profiles with existing interpolated measurements. The instrument is designed for long-term, unattended deployment of up to two years and will be integrated either within existing syntactic buoyancy elements or via a seabed-mounted configuration, depending on final operational requirements.
