Project anatomy
Contract scope and delivery roles
- Client / authority
- National Oceanography Centre
- Delivery parties
- Seawork Marine Services, Companies House 00721735 - confirmed signed supplier; the notice narrative also uses Sea Works Marine and SeaWork Marine Ltd, Associated British Ports - Southampton docks landlord and nominated-supplier context only; not identified as the contracting authority or works contractor, Design, survey, diving, materials, plant and any other downstream parties - not identified in the cited sources
- Contract route
- Procurement reference NOCP00510 used a below-threshold procedure without competition under OCID ocds-h6vhtk-0500a2. NOC stated that its ABP tenancy obliged it to use ABP's preferred or nominated supplier. The UK7 contract-details notice records signature on 8 May 2025.
- Execution window
- The April 2025 transparency notice estimated work from 7 to 25 July 2025. The later signed-contract notice changed the period to 13 August through 12 September 2025. Use the later dates as the contractual baseline, but not as evidence of mobilisation, completion or acceptance.
- Works package
- Quayside wall and pontoon repairs at the National Oceanography Centre's Southampton site. Although the procurement is titled Sea Wall Repairs and uses sea-wall construction CPV 45243300, the notices provide no wall length, pontoon count, repair method, structural detail, material quantity, utility scope or temporary-works boundary.
- Marine interfaces
- The work sits at NOC's waterfront site inside Southampton Docks. Quayside and pontoon repairs create live-water, access and operational interfaces, but the cited procurement record does not identify navigation restrictions, marine plant, diving, hydrographic survey, environmental controls or coordination measures.
- Commercial evidence boundary
- The signed value is GBP 88,800 including VAT. No excluding-VAT value, payment schedule, measured-work basis, variation, retention, final account or lower-tier allocation is disclosed. The direct route is explained through NOC's ABP tenancy and nominated-supplier obligation; it does not establish ABP payment or package ownership.
