UK Navy Future Dredging Contract

Participation source

The Ministry of Defence's 3 July contract-details release records the Navy Future Dredging Contract as signed with Boskalis Westminster on 1 April 2026 for GBP 9.2 million excluding VAT. Its initial term runs through 31 March 2028, with two potential one-year extensions. This advances March's award decision to an executed contract, without establishing delivery of a named dredging campaign. A 14 September UK7 correction changes the contract number to 715891477.

Project anatomy

Contract scope and delivery roles

Client / authority
UK Ministry of Defence / Defence Infrastructure Organisation
Delivery parties
Boskalis Westminster Limited
Contract route
Competitive flexible procedure under the defence and security regime. The tender used a 70% quality and technical weighting and 30% price weighting. Two tenders were received and assessed; Boskalis Westminster was selected and Van den Herik UK was identified as the unsuccessful supplier.
Execution window
The 3 July UK7 release gives a 1 April 2026 signature and initial term from 1 April 2026 to 31 March 2028, with a maximum extension date of 31 March 2030. Two one-year options require the employer's extension notice. Campaign mobilisation, work quantities and acceptance need separate dated evidence.
Works package
Dredging works in and around UK naval ports, primarily Plymouth and Portsmouth during the initial period. The reviewed procurement releases do not specify accepted dredged quantities, achieved depths or campaign completion. July's contract release also identifies signed-contract, scope and KPI attachments; their existence is not proof of delivered site outputs.
Marine interfaces
Delivery will have to be coordinated inside live and security-controlled naval ports where navigation access, berth availability, vessel movements, survey control, environmental compliance, dredging plant, sediment routing, and operational windows can constrain each other. Those interface requirements are decision-relevant, but their project-specific controls are not disclosed in the public notice chain.
Commercial evidence boundary
The GBP 9.2 million figure is now supported by the signed-contract record rather than only the award decision. It remains distinct from the GBP 16 million tender estimate. Neither value proves a saving, a changed scope or a per-campaign budget. July's agreed metrics address pre-commencement documentation, survey reporting, KHM and port-operation compliance, safety, log sheets, supervision, variations and environmental delivery. They are performance requirements, not recorded scores or evidence of compliance.

UK7 correction updates the contract number

The UK7 update changes the contract number to 715891477; the official history retains the 1 April signature, Boskalis Westminster, GBP 9.2 million excluding VAT and the initial term through 31 March 2028. Campaign delivery and measured KPI results remain unverified.

Contract-details release records signature and performance requirements

The official UK7 release records an April signature, GBP 9.2 million value and initial term to March 2028. It identifies survey reporting, port-operation compliance, safety, logging and environmental metrics, without demonstrating any campaign's accepted quantities or navigation depths.

Source

The Ministry of Defence published its Boskalis award decision

The UK6 notice named Boskalis Westminster, recorded a £9.2 million value excluding VAT, two assessed tenders, an earliest signature date of 27 March 2026, and an estimated initial term to March 2028. The decision selected the supplier; signature, notice to proceed, mobilisation, dredging and accepted naval-port access remained open.

Source

The formal tender opened the competitive procedure

The UK4 notice set a competitive flexible procedure, a £16 million estimate, 70% quality and technical weighting, 30% price weighting, and two optional one-year extensions. The estimate described the tender, not an executed contract value, final scope or saving benchmark.

Source

The planned procurement notice formalised the future competition

The UK3 notice advanced the requirement from market engagement toward a stated defence dredging procurement. It did not appoint a supplier, define individual Plymouth or Portsmouth campaigns, disclose dredged quantities or sediment routes, or authorise field work.

Source

Preliminary market engagement tested supplier capacity

The UK2 notice opened early engagement around the Navy Future Dredging Contract requirement. Market engagement was evidence of requirement formation only; it was not a tender, award, contract, work package, mobilisation record, or delivered navigation outcome.
