## Summary

The National Oceanography Centre bought an automated flow-through total alkalinity analysis system for continuous underway measurement in marine research. The requirement covers supply, installation and commissioning, with associated software, integration support, training, warranty and initial consumables to bring the system into operational service. It will collect high-resolution total alkalinity data alongside existing underway pCO₂ measurements, supporting characterisation of the marine carbonate system and ocean acidification research. This is a goods procurement for an analyser (CPV 38434000), delivered in Southampton. The buyer is a public-sector oceanographic research organisation, so relevant suppliers are those able to provide and support specialist marine or laboratory analysis equipment in a research environment.

The procurement is complete and has been awarded. It used a below-threshold direct award without competition. PLANET OCEAN LIMITED was selected for the single lot. The contract was signed on 20 August 2026 and runs from 20 August 2026 to 19 August 2027. Its value is £41,000 excluding VAT, or £49,200 including VAT. The published information identifies the award as an active award and the contract as active. The procurement was evaluated through the direct-award route rather than a competitive tender, and the recorded outcome is the appointment of PLANET OCEAN LIMITED to provide the analyser system and associated commissioning and support requirements.

For a supplier considering future work with the National Oceanography Centre, this procurement demonstrates demand for integrated scientific instrumentation rather than a standalone piece of equipment. A credible competitor would need to supply an automated flow-through total alkalinity analyser suitable for continuous underway marine measurements, and support its installation and commissioning. Relevant capability also includes software provision or integration with existing underway pCO₂ measurement systems, user training, warranty support and initial consumables. Experience of delivering reliable analytical equipment for oceanographic, marine-carbonate or ocean-acidification research would strengthen a future proposition. The requirement was met by an SME supplier, indicating that a specialist equipment business with the necessary technical support capacity can serve this buyer.
