## Summary

The Scottish Government’s Marine Directorate sought a conductivity, temperature and depth (CTD) instrument with associated oceanographic sensors. The equipment is intended to measure seawater characteristics accurately for environmental monitoring, helping quantify and understand changes in Scottish waters arising from natural variability and human activity, including climate change. It will be used primarily by the Directorate’s Oceanography team, with potential use by colleagues working in fisheries, marine renewables, aquaculture and nature conservation. The instrument is for use around Scotland and offshore. This is a goods procurement for oceanographic and hydrographic surveying equipment, including sensors, rather than a service or works contract.

The buyer invited tenders through an open procedure. The procurement has reached the tender stage; the stated submission deadline was 30 November 2026 at 12:00 UTC, with the bid opening scheduled for the same time in Aberdeen. The planned contract period runs from 6 January to 31 March 2027. The estimated contract value is £150,000. There is one lot, and variants are not allowed. Bids are assessed on quality and price: the listed quality criteria cover the technical solution and delivery, staff and organisational experience, contract management and quality assurance, corporate and social responsibility, and Fair Work First. The tender describes question scoring from 0 to 4, while the listed criteria assign quality 60, 15, 15, 5 and 5 points respectively, alongside a price criterion of 30.

This opportunity suits suppliers able to provide a CTD instrument and associated sensors for marine environmental monitoring, with relevant supply experience and the technical facilities, equipment and staff to deliver the requirement. Bidders are required to give three examples of relevant work from the previous five years and explain the technicians, facilities, supply-chain tracking, environmental management, tools and equipment they can draw on. The buyer also requires evidence of quality-management capability: either a UKAS-accredited (or equivalent) ISO 9001 certificate, or a documented, senior-authorised quality policy that is reviewed periodically and appropriate to the work. Financial qualification requirements include at least £250,000 in specific annual turnover in each of the previous two years, a current ratio above 0.8 and positive net profit across the two-year cycle. Employers’ liability cover must meet legal requirements and public liability cover must be £1 million.

## Notice

The Scottish Ministers, Marine Directorate invites tenders for the purchase of a Temperature, Conductivity and Depth (CTD) instrument with associated oceanographic sensors.

### Lot Information

Lot 1

The Scottish Ministers wish for the provision of a CTD instrument and associated sensors for the accurate measurement of the characteristics of sea water for environmental monitoring to quantify and understand trends and variability in Scottish waters, as a result of natural variability and human activities, including climate change. The equipment will be primarily used by the Oceanography delivery area but also potentially by colleagues in other areas (fisheries, marine renewables, aquaculture, nature conservation) who require a good understanding of the physical environment.
