Award Notice
Summary of the contracting process

The Ministry of Defence procured underwater engineering services for Royal Navy and Royal Fleet Auxiliary vessels. The work covers inspections, repairs, husbandry and maintenance at or below the waterline, supporting safe, compliant and efficient vessel operation and reducing the need for costly, disruptive dry-docking. The service is classified as vessel repair services (CPV 50241100), with related engineering support, technical inspection, maritime safety inspection and diving activities. Delivery is centred on the Ministry of Defence site at Abbey Wood, Bristol, and the South West of England. This is a specialist marine engineering and diving requirement for suppliers able to work on operational naval and auxiliary vessels and support their availability.

This procurement has been completed and awarded following a selective competitive procedure with negotiation above the applicable threshold. The submission deadline was 5 August 2026, and the contract was awarded on 6 August 2026 to SeaTec UK Ltd. The awarded value is £6,200,000. The contract runs from 13 August 2026 to 13 August 2031. The requirement was treated as a services contract and was not identified as suitable for small or medium-sized enterprises or voluntary, community and social enterprises. The award covers one underwater engineering services lot. Evaluation used the negotiated competitive process; detailed quality and price weightings are set out in the procurement documents.

For suppliers that did not win this award, the procurement demonstrates sustained Ministry of Defence demand for specialist underwater engineering supporting naval vessels. A credible competitor for a future requirement would need practical capability in below-waterline inspection, repair, husbandry and maintenance, together with marine technical inspection and diving expertise. It would need to demonstrate safe, compliant delivery in a defence environment, including the ability to protect vessel availability and reduce reliance on dry-docking. The scale and specialist nature of the work favour established providers with substantial operational capacity, suitably qualified engineering and diving personnel, robust safety and quality controls, and experience coordinating work on Royal Navy or comparable maritime assets. The negotiated procedure also makes strong technical and commercial engagement important.
