DE&S play a critical role in keeping the United Kingdom safe and prosperous, and making sure the front-line have the right kit at the right time. From fighter jets to food deliveries, from patrol boats to protective clothing, DE&S deliver effective and innovative kit to front-line forces.\nWithin the new DE&S structure, the Power Propulsion and Auxiliary (PPA) team has been set up as a technology area, working across different areas of defence to deliver and sustain systems that generate operational energy, to provide propulsion (e.g. prime movers/engines and transmissions fitted to platforms), and cross-cutting auxiliary systems, including life support, fire-fighting, medical, and catering equipment.\nWorking as a pan-environment team across different areas of Defence, PPA have a requirement to support and maintain the production of fresh (potable) water using reverse osmosis and distillation processes to support habitability, including drinking water and hotel services for its maritime environment. Additionally, the de-mineralised water has a technical use which currently supports a number of Royal Navy master equipments. As part of this market engagement, PPA wishes to explore how it may incorporate its water purification requirement for its Army master equipment.",

                        "description": "714655452 - MSS/144 – Fresh Water and Technical Water Production\nREQUIREMENT\nDE&S PPA has a requirement for In-Service Support of systems and equipments for the production of fresh (potable) water using reverse osmosis and distillation processes to support habitability including drinking water and hotel services for its maritime environment, and de-mineralised water for technical use in support of a number of Royal Navy master equipments.  The scope will initially include systems and equipments which are currently in service,  with the option to include additional systems as they enter service.\nThe requirement will include the supply of permanent and consumable spares, repair and maintenance activities, technical and post design services (including obsolescence management), and supply chain management.\nThe Authority does not currently envisage that the requirement will be divided into Lots, however the Authority reserves the option to change this approach at any step/stage of the tendering procedure\nIt is anticipated that the Tender Notice will be issued circa 15 December 2025.  Further information regarding the anticipated procurement schedule will be published in the Tender Notice when issued, however it is envisaged that any resultant contract will commence circa 01 September 2026 with an initial term of 3 years with three option periods of 2 years each.  The Authority also reserves the option to change this approach and add or remove steps/stages at any step/stage of the tendering procedure.\nYou must not take this announcement as confirmation that MOD shall award a contract for this requirement.  The MOD is publishing this announcement without any commitment to issue a tender or place a contract.  Accordingly, any expenditure, work or effort undertaken before contract award is a matter solely for the commercial judgement of potential suppliers\nFor the purposes of Cyber Security, this requirement has been assessed as Low Risk (RAR 240731A02).\nBACKGROUND\nDefence Equipment and Support (DE&S) is an arm’s length body of the Ministry of Defence, which delivers equipment and support services to the Royal Navy, British Army, and Royal Air Force. DE&S play a critical role in keeping the United Kingdom safe and prosperous, and making sure the front-line have the right kit at the right time. From fighter jets to food deliveries, from patrol boats to protective clothing, DE&S deliver effective and innovative kit to front-line forces. \nWithin the new DE&S structure, the Power Propulsion and Auxiliary (PPA) team has been set up as a technology area, working across different areas of defence to deliver and sustain systems that generate operational energy, to provide propulsion (e.g. prime movers/engines and transmissions fitted to platforms), and cross-cutting auxiliary systems, including life support, fire-fighting, medical, and catering equipment. \nPreliminary Market Engagement (PME) was conducted during May 2025.  The Authority has completed it’s consideration of the outcomes of this engagement and is now preparing to issue a UK4 – Tender Notice for the purposes of conducting a Competitive Flexible Tender Procedure as regulated by the Procurement Act 2023.  It should be noted that the PME also explored how it may incorporate its water purification requirement for its Army master equipment, however the Authority does not currently plan to include the Army Master Equipment requirement within this procurement.\nPrevious notices can be found on Find a Tender Service under the following references:\nProcurement identifier (OCID):               ocds-h6vhtk-0504d5\nUK1 – Pipeline Notice:\nNotice Identifier:             2025/S 000-023114\nPublished:                         20 May 2025, 11:27am\nNotice Title:                      714655452 - MSS/144 - Water Purification Equipment - UK1 Pipeline Notice\nUK2 – Preliminary Market Engagement Notice:\nNotice Identifier:             2025/S 000-015905\nPublished:                         17 April 2025, 1:23pm\nNotice Title:                      714655452 - MSS/144 Water Purification Equipment",

The requirement will include the supply of permanent and consumable spares, repair and maintenance activities, technical and post design services (including obsolescence management and disposals), and supply chain management. \nThe intended equipment scope of the contract will include support to the following Fresh Water/Technical water Production Master Equipment: \n•\tReverse Osmosis Plants, \n•\tEvaporator / Distilling Units, \n•\tFresh Water Embarkation Units,  \n•\tPotable Fresh Water Dosing.\nThe equipment included within the scope of the contract is mature technology developed from the commercial market over the last 30 years and is fitted to the current RN Fleet, RFA Fleet and other Foreign Navy vessels, and is widely used in commercial shipping, including tankers, cruise liners etc. This range of equipment is in the In-Service phase of the CADMID cycle. \nThe contract consists of circa 1,500 line items, the majority of which are NATO codified. \nThe equipment range encompasses multiple Original Equipment Manufacturer (OEM) supplied equipment. The level of support provided by OEMs ranges from the supply of spares only, through to technical support and repair. The management of OEMs will be the responsibility of the contractor. \nThis tender notice is for the award of a public contract through a competitive flexible procedure in accordance with section 20(1) and (2)(b) of the Procurement Act 2023. It is considered a Defence and Security Contract due to its scope and therefore the relevant provisions of the Procurement Act 2023 relating to defence and security contracts are applicable.\nThere will be a requirement for Post Design Services outside of the core requirement and a tasking process will be included for this.  \nThe Cyber Risk Profile for this requirement identified by the Cyber Risk Assessment is Level 3 (Expert) Reference - RAR-CKQ9-4ZV.  \nIt is anticipated that TUPE will apply to this requirement.",

This will also include the assessment of whether a supplier, its connected persons, associated persons or any intended subcontractors are excluded or excludable persons under the Procurement Act 2023. A clarification process will be used during the PSQ period to allow suppliers to seek clarification from the Authority.\nWithin the PSQ there are a mix of questions which are Pass/Fail and Scored. A Fail will result in the potential provider being excluded from further participation in the tendering process. For those suppliers who pass all of the Pass/Fail questions, their overall technical score will determine their ranking. Those ranking in the Top 5 will be invited to Tender.\nWhere there is a tie at Position 5, the decision on which supplier will be Invited to Tender will be based initially on the highest score on question 1 of the Technical Conditions of Participation. Where this still results in a tie, the decision will be based on the highest score for question 2. This will continue sequentially down the list for Questions 1 to 4 until a supplier is selected for 5th place. If this sequential process does not result in a clear 5th place then the Authority reserves the right to proceed to tender with additional suppliers who share equal 5th position.\nAn Invitation to Tender (ITT) will be issued to those successful at PSQ. A clarification process will be used during the tendering period to allow suppliers to seek clarification from the Authority. A summary of the award criteria is in this notice and will be explained in the Tender Evaluation Strategy, which will be published in the DSP, with the ITT. \nThe Authority reserves the right to refine the award criteria before and - where negotiation/final tenders are used - during the Tender period in accordance with section 24 of the Procurement Act 2023. \nThis may include revision to the weightings of the sub-criteria.\nThe following supplementary processes may be used, with further details set out in the additional tender documents;\n• Clarifications - during the tender evaluation period\n• Negotiations - following evaluation of the Tender\n• Final Tenders - following negotiations, if used\n• Preferred Supplier Stage - to confirm solutions and/or finalise the draft contract.\nThe Authority reserves the right to amend the procurement, where such amendment would not be substantial, as follows, including and not limited to;\n• amendments to the tender documents which may provide clarification\n• refining the specification as the competitive flexible procedure progresses\n• reducing timescales.\nIf any amendments are made, the Authority will consider whether any applicable tender deadlines should be revised, and whether any tender documents or notices need to be re-issued.\nThe Contracting Authority reserves the right to directly award a contract for similar goods or services without further competition pursuant to Schedule 5 paragraph 8, including to other parts of the Ministry of Defence.\nA tenderers' conference is to be held online via MS teams for the 5 potential providers who are given an ITT. \nThe date will be confirmed when the ITT is released on the Defence Sourcing Portal. The Authority will issue invitations to the tenderer’s conference using the messaging facility on the Defence Sourcing Portal. Further details of the conference can be found within the DEFFORM 47."

If this sequential process does not result in a clear 5th place then the Authority reserves the right to proceed to tender with additional suppliers who share equal 5th position.\nAn Invitation to Tender (ITT) will be issued to those successful at PSQ.

This will also include the assessment of whether a supplier, its connected persons, associated persons or any intended subcontractors are excluded or excludable persons under the Procurement Act 2023. A clarification process will be used during the PSQ period to allow suppliers to seek clarification from the Authority.\nWithin the PSQ there are a mix of questions which are Pass/Fail and Scored. A Fail will result in the potential provider being excluded from further participation in the tendering process. For those suppliers who pass all of the Pass/Fail questions, their overall technical score will determine their ranking. Those ranking in the Top 5 will be invited to Tender.\nWhere there is a tie at Position 5, the decision on which supplier will be Invited to Tender will be based initially on the highest score on question 1 of the Technical Conditions of Participation. Where this still results in a tie, the decision will be based on the highest score for question 2. This will continue sequentially down the list for Questions 1 to 4 until a supplier is selected for 5th place. If this sequential process does not result in a clear 5th place then the Authority reserves the right to proceed to tender with additional suppliers who share equal 5th position.\nAn Invitation to Tender (ITT) will be issued to those successful at PSQ. A clarification process will be used during the tendering period to allow suppliers to seek clarification from the Authority. A summary of the award criteria is in this notice and will be explained in the Tender Evaluation Strategy, which will be published in the DSP, with the ITT. \nThe Authority reserves the right to refine the award criteria before and - where negotiation/final tenders are used - during the Tender period in accordance with section 24 of the Procurement Act 2023. \nThis may include revision to the weightings of the sub-criteria.\nThe following supplementary processes may be used, with further details set out in the additional tender documents;\n• Clarifications - during the tender evaluation period\n• Negotiations - following evaluation of the Tender\n• Final Tenders - following negotiations, if used\n• Preferred Supplier Stage - to confirm solutions and/or finalise the draft contract.\nThe Authority reserves the right to amend the procurement, where such amendment would not be substantial, as follows, including and not limited to;\n• amendments to the tender documents which may provide clarification\n• refining the specification as the competitive flexible procedure progresses\n• reducing timescales.\nIf any amendments are made, the Authority will consider whether any applicable tender deadlines should be revised, and whether any tender documents or notices need to be re-issued.\nThe Contracting Authority reserves the right to directly award a contract for similar goods or services without further competition pursuant to Schedule 5 paragraph 8, including to other parts of the Ministry of Defence.\nA tenderers' conference is to be held online via MS teams for the 5 potential providers who are given an ITT. \nThe date will be confirmed when the ITT is released on the Defence Sourcing Portal. The Authority will issue invitations to the tenderer’s conference using the messaging facility on the Defence Sourcing Portal. Further details of the conference can be found within the DEFFORM 47."
