What is being bought

Published requirement description

The National Oceanography Centre (NOC) is looking to establish an open framework for the refit, maintenance, equipping and sustainment of its operational research vessels, including RRS James Cook and RRS Discovery, together with associated marine assets and scientific systems, across their working life. The support sought is expected to include the following broad areas, which are indicative and not exhaustive.

Refit and docking support across the classification cycle, including the intermediate and special survey work falling due within it, broadly covering hull, structural and coating work, propulsion and steering intervention, tailshaft and rudder work, and the repair and renewal identified through survey. Both wet berth and dry dock coverage will be needed over the life of the framework, and the structure will be designed to accommodate suppliers offering either or both.

General marine engineering and support capability, required both during refit periods and on an ongoing basis outside them, in the United Kingdom and overseas, broadly covering marine mechanical and electrical engineering, fabrication, pipework and hydraulics, HVAC, cabling and systems installation, interior works, running maintenance, defect rectification, modification, and commissioning and mobilisation to port.

Support for critical vessel systems, from original equipment manufacturers and their approved partners, broadly covering propulsion, engines and gearboxes, navigation and bridge systems, communications and information and operational technology, electrical distribution and generation, safety and lifesaving systems, and control, automation and energy management, together with the inspection, overhaul, upgrade and certification these systems require.

Support for marine research and survey systems, including supply, installation, integration, calibration, servicing and upgrade, broadly covering multibeam and singlebeam echo sounders, sub bottom profilers and acoustic positioning, oceanographic and environmental sensors and sensor packages, water column and seabed sampling systems, deck handling and over the side deployment equipment, and the associated data acquisition, processing and control infrastructure.

Technical and professional marine services, independent of the yards, broadly covering naval architecture, marine surveying, superintendency, class liaison, project and programme management and specialist engineering consultancy.

Supply of maritime hardware on a supply only basis, broadly covering equipment, spares, components and consumables, including original equipment manufacturer and approved equivalent parts.

Capability for decarbonisation and environmental retrofit is of interest across all of the above.

The framework is expected to be divided into lots. The lot structure, the number of suppliers appointed to each lot and the call off mechanisms will be confirmed following preliminary market engagement. Suppliers will be able to apply for one or more lots, and geographic capability, together with dry dock or wet berth capability, will be recorded at framework stage.

NOC will be the sole contracting authority. The framework is expected to be established as an open framework under the Procurement Act 2023, with a duration of up to eight years, and will be reopened to new suppliers at points set out in the framework documents. Work will be ordered by call off contract on a task by task basis, covering both programmed and unplanned requirements, at yards, ports and NOC sites in the United Kingdom and overseas. Call off routes are expected to include direct award and further competition among the suppliers appointed to the relevant lot, with the applicable route set out in the framework at the outset.

The estimated total value of the framework is estimated to be worth between £65,000,000 & £100,000,000 excluding VAT over its full duration. No guarantee of volume or value is given to any supplier appointed to the framework.

How did awards compare with estimates?

i

Where winning prices landed against estimates.

Each colour shows awards below, close to or above the published estimate, one lot at a time.

On a framework or DPS, prices are agreed when work is called off.

Past prices are a guide, not a bid price.

Last 36 months.

Not comparable on a framework or DPS. The notice sets up a supplier panel and a ceiling value; what the work actually costs is agreed later, on each call-off or mini-competition, and those publish as contract notices of their own. The award-vs-estimate record of this market therefore sits on the call-offs; this page shows it on the contracts, not on the panel that frames them.

About this data
  • Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
  • Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
  • Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
  • Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.

    Purpose and scope of the engagement:

    NOC is undertaking preliminary market engagement ahead of establishing this framework. The purpose is to allow the market to shape it before any tender documents are prepared. Engagement will cover all aspects of the requirement set out above, including the grouping of services and the lot structure, the number of suppliers to be appointed to each lot, call off mechanisms, the recording of geographic and dry dock or wet berth capability, and the practical operation of an open framework over an eight year term. Nothing is fixed and supplier input may change any of it.

    How to express interest

    Suppliers wishing to take part should complete the registration form below:

    forms.cloud.microsoft/e/xaKC8NASbR ↗

    The form records supplier contact details and asks which engagement activities are relevant to your organisation. NOC will use it to issue invitations, questionnaires and further information. Registration remains open throughout the engagement period, although suppliers registering later may not be able to take part in activities already held.

    Engagement activities

    The activities that follow will depend on the responses received. They may include any of the following:

    • a further market engagement questionnaire
    • a general supplier day or briefing event
    • targeted one to one meetings with NOC
    • supplier presentations or demonstrations of relevant services, technology or capability
    • site visits, shipyard visits, workshop visits or operational demonstrations
    • written feedback on proposed service groupings or scope
    • collaborative or technical workshops

    Participation is voluntary and suppliers may take part in some, all or none of these activities.

    Locations and dates:

    Dates, formats and attendance arrangements are not yet fixed. NOC currently expects preliminary market engagement to conclude by December 2026 and will update the market if that period changes. Events may be held at NOC premises in Southampton or Liverpool, online, or at supplier, yard or workshop premises where a visit or demonstration is involved. Dates, venues and joining arrangements will be confirmed directly to registered suppliers.

    Clarification questions:

    Clarification questions should be sent by email to [email protected], quoting reference 2026PRNOC-1217 in the subject line. NOC will not respond individually where a question and its answer are of general application. Those will be issued to all registered suppliers with the identity of the questioner withheld.

    General:

    Participation is not a condition of taking part in any future procurement, and taking part or not taking part will neither advantage nor disadvantage any supplier. Information provided during engagement is indicative only and does not commit NOC to any particular scope, structure, value or timetable, or to proceeding with the procurement. Costs incurred by suppliers in taking part will not be reimbursed.

    One thing worth deciding before publication: whether general clarification responses go only to registered suppliers, as drafted, or are published more widely. Restricting them to the form registration list is defensible, but it does mean a supplier who reads the notice and does not register will not see them.
