Summary of the contracting process

The Ministry of Defence procured underwater engineering services for Royal Navy and Royal Fleet Auxiliary vessels. The requirement covers inspections, repairs, husbandry and maintenance at or below the waterline, supporting compliant, safe and efficient vessel operation and reducing the need for disruptive dry-docking. The work includes vessel repair, engineering support, technical inspection of engineering structures, maritime safety inspection and diving services. Delivery is across the UK and, under the awarded arrangements, outside the UK. This is a defence services requirement managed by the Ministry of Defence from Bristol. It is relevant to marine engineering, ship repair, underwater inspection, diving, salvage and related technical service providers able to support naval and auxiliary vessels.

The procurement is complete and used a selective competitive procedure with negotiation. The published outcome records Sea Tec UK Ltd as supplier for both awards, with three bids recorded for one lot and two for the other. One contract, for underwater engineering services outside the UK, is active at £65,000,000; the other, for Salvage and Marine Operations, is active at £6,200,000. Both contracts were signed on 13 August 2026. The tender recorded a total estimated value of £100,000,000, with a minimum estimated value of £20,000,000, but these are not added to the awarded contract values. Price was the stated evaluation criterion. The tender records two lots as cancelled, while active awards and contracts are recorded against them. Each arrangement included two one-year extension options.

This outcome indicates demand for suppliers that can deliver underwater engineering and salvage or marine operations for naval and auxiliary vessels, including work below the waterline. Credible competitors would need practical capability in underwater inspection, repair, husbandry, maintenance, diving, maritime safety inspection and engineering support, with the technical discipline to keep vessels compliant, safe and operational while avoiding dry-docking. The requirement also points to the ability to work both in the UK and internationally, depending on the service package. The selected supplier was a large organisation, and the use of a negotiated competitive procedure with price as the stated criterion suggests that bidders needed a clear, commercially competitive cost model alongside dependable delivery capability. Relevant marine engineering capacity, safety controls and experience supporting defence vessels would strengthen a future response.
