UK5 - Transparency Notice
Summary of the contracting process

The Met Office is procuring Motus Wave Sensors as and when required, with a one-year warranty for each supply. These are marine monitoring instruments used across the Met Office’s Marine Moored Buoy Network and moored oceanographic and atmospheric data buoys, where they provide wave measurements. The requirement supports replacement of existing sensors that are beyond economical repair and maintains consistent technology across the fleet. The goods are to be delivered for use in the United Kingdom. The procurement is for goods, classified as marine equipment. The buyer is the Met Office, a central government public authority based in Exeter. The requirement covers one complete lot and allows additional purchases of the same wave sensor during the contract.

The procurement is complete and has been awarded by direct award to Aanderaa Data Instruments AS. The award was made on 19 August 2026, following a transparency notice and a standstill period ending on 7 September 2026. The contract was signed on 10 September 2026 and runs from 28 September 2026 to 27 September 2030, with an option to extend to 27 September 2032. The contract value is £132,000 excluding VAT and £162,000 including VAT. The Met Office justified the direct award because Aanderaa’s Motus sensor is the sole wave sensor used across its moored buoy sites, has already been integrated through substantial engineering work, and has demonstrated accurate and reliable performance. The contract also permits further purchases of the same sensor.

This requirement is most relevant to suppliers with marine instrumentation expertise, established wave-sensing technology and the engineering capability to integrate sensors into moored buoy networks. The award shows that the Met Office values continuity of supply, standardised fleet technology and technically identical outputs that allow scientific readings to be compared reliably over time. A credible future competitor would therefore need to demonstrate dependable sensor performance in marine conditions, compatibility with the Met Office’s existing network and the capacity to supply replacement equipment as required. Experience supporting installed monitoring systems, maintaining consistent data outputs and providing warranty-backed equipment would strengthen a supplier’s position. The incumbent is a Norwegian SME, showing that specialist overseas manufacturers can meet this type of public-sector requirement.

Notice Information

Notice Title

Supply of Motus Wave Sensors

Notice Description

Supply of Motus Wave Sensors as and when required by Met Office with one year warranty. This Contract shall commence on the Contract Start Date and shall remain in force for an initial period of four (4) years from the Contract Start Date (the "Initial Period"). The Contract may be extended at the end of the Initial Period for a further period of two (2) years ("Optional Extension Period") by the Met Office giving written notice of extension to the Supplier no later than 3 months prior to the expiry of the Initial Period.

Procurement Information

New sensors will be required to replace existing stock deemed beyond economical repair for 2027 and beyond. The Marine Moored Buoy network exclusively uses the Motus Wave sensor. Aanderaa no longer have a UK distributor for the Motus Wave Sensor. A significant amount of engineering effort has been dedicated to integrating MOTUS wave sensors into the Marine Moored Network, where they are the sole wave sensor used by the Met Office across our Moored ODAS buoy sites. Previous acceptance trials have demonstrated that MOTUS is an exceptionally accurate and reliable sensor. Continuity of sensor supply enables standardisation of fleet technology and provides technically identical outputs for reliable scientific comparability of readings.
