## Summary

The National Oceanography Centre bought two long-range Doppler velocity logs (DVLs), navigational instruments used as a critical component in two new systems for its expanding autonomous long-range (ALR) fleet. The equipment supports the centre’s oceanographic operations by providing velocity measurements for those systems. The buying organisation is the National Oceanography Centre, based in Southampton. Delivery is in the United Kingdom; the procurement data identifies the destination region as South East England. This is a goods requirement for specialist marine navigation and measurement equipment, rather than a general supply of oceanographic services or fleet support.

The procurement is complete and the contract has been awarded to Nortek Instruments Limited. The centre used a direct award below the applicable threshold, without competition. There was one lot, covering the two DVLs. The contract was signed on 28 September 2026 and runs from 28 September 2026 to 27 September 2027. Its value is £62,034 excluding VAT (£74,440 including VAT). The award is active, and the contract is active. The published process data does not state award evaluation criteria or supplier eligibility conditions; the direct, non-competitive route means there was no competitive evaluation among bidders described here.

For suppliers competing for a future requirement from the National Oceanography Centre, this award demonstrates demand for specialist DVL equipment integrated into autonomous long-range fleet systems. A credible supplier would need to provide instruments suitable for the centre’s ALR system configuration and capable of supporting its operational use, as well as the technical expertise to supply equipment that functions as a critical system component. The requirement was for two units, indicating a focused equipment purchase rather than a broad service programme. Nortek Instruments Limited, an SME, was selected through a direct award below threshold without competition. Suppliers with relevant marine navigation instrumentation and experience supplying equipment for integration into autonomous oceanographic platforms are the closest fit to this demonstrated requirement.

## Notice

NOC requires two DVLs to support the expansion of its ALR fleet. The DVLs are a critical component of the ALR system configuration and will be used within two new systems being added to the fleet.
