Summary of the contracting process

Associated British Ports procured capital dredging works for channel deepening at the Port of Southampton and in the Nab Deep Water Channel. The requirement covers dredging for disposal at sea, enabling activities and mitigation of marine unexploded ordnance risks. Work includes dredging beside an operational quay wall and in areas containing buried pipelines, while maintaining safe port navigation and quayside operations. The procurement is for works, classified as dredging and pumping works (CPV 45252124). Delivery is in Southampton, at the Port of Southampton and the Nab Deep Water Channel. ABP is the buyer and operates a large UK port network, with Southampton serving container, automotive, cruise and bulk cargo traffic.

The procurement is complete and a supplier has been selected through a two-stage negotiated Competitive Flexible Procedure under the utilities regime. The conditions of participation stage closed on 6 February 2026 at 12:00 noon, followed by the Invitation to Tender stage. The award decision date was 11 August 2026, with a standstill period ending on 21 August 2026. Boskalis Westminster Limited was selected for the single lot. The awarded value is recorded as £0 gross. The award contract period is 1 September 2026 to 31 July 2027. A contract signature milestone was scheduled for 30 August 2026. Evaluation was expected to give 60% weighting to commercial factors and 40% to technical factors, subject to change.

This requirement indicates demand for a principal contractor able to deliver major marine dredging in a live commercial port. A credible future competitor would need suitable dredging plant and equipment for disposal at sea, work beside operational quay walls and operate safely around buried pipelines. It would also need proven experience of projects of a similar scale, together with the capability to plan and control works without disrupting port navigation or quayside operations. Relevant expertise in identifying and mitigating marine unexploded ordnance risk would be important, as would the capacity to manage enabling activities alongside the main dredging operation. The buyer’s use of a two-stage Competitive Flexible Procedure means suppliers should be prepared to demonstrate participation-stage capability before submitting a detailed tender.
