Naval-port dredging makes access readiness the real award test

What changed

The UK6 award notice confirms Boskalis Westminster, a £9.2 million value excluding VAT, Plymouth and Portsmouth as the initial focus, an estimated two-year term, two performance- and need-dependent one-year options, and two assessed tenders. The UK4 tender notice confirms a £16 million estimate, 70% quality and technical weighting, 30% price weighting, and a competitive flexible procedure under the defence and security regime. UK2 and UK3 document the earlier market-engagement and planning sequence. Quantities, port sub-packages, environmental controls, disposal routes, mobilisation, accepted depths and a signed contract are not disclosed.

Why it matters

Naval-port dredging is not complete when plant arrives or material is removed. Each campaign has to preserve fleet movements, work within restricted operating windows, control sediment and placement routes, maintain survey traceability, and demonstrate an accepted navigational result. The optional years are expressly linked to contractor performance and continuing operational need, so execution evidence can affect both access readiness and future contract value.
