Published justification

The Sense, Decide and Communicate C2TNC (SDC C2TNC) Project Team within Defence Equipment & Support (DE&S), part of the UK Ministry of Defence, (“the Authority”) intends to enter into a contract (the Contract) with OSI Maritime Systems Ltd (“the Contractor”) for the combined procurement of an upgrade for the Royal Navy Warship Electronic Chart Display And Information System (RN-WECDIS) and the Warship Automatic Identification System (WAIS) Obsolescence Recovery, in addition to these systems’ maintenance, technical support and training in the use of these systems.

Navigation capability on RN platforms is a critical component of its ability to operate and fight. WECDIS and WAIS capabilities across the fleet are required to meet regulatory compliance utilising the software provided by the Company. This requirement includes work to address obsolescence recovery for WAIS and WECDIS, radar control software and the provision of associated spares. Only the Contractor has the necessary technical information to be able to perform this requirement on all platforms within scope, without considerable risk to the continued operation of the fleet. Their continued technical expertise, technical data and manufacturing expertise is necessary to ensure that these systems remain fully operational and compliant.

The length of the new contract will be 2 years. The approximate value of the contract is estimated to be £20m ex VAT.

In accordance with Section 41(1)(a) of the Procurement Act 2023 (the “Act”), the Authority intends to rely on the Single Supplier direct award justification, as set out in Paragraph 6 of Schedule 5 of the Act, to award a public contract directly to the Contractor, a supplier that is not an excluded supplier. It is considered that a Direct Award is permissible under the Act on the basis that, due to an absence of competition for technical reasons, only the Contractor can carry out the services and there are no alternatives to those goods, services or works.

Only the Company possesses the technical information to carry out the work required to achieve the ECPINS (Electronic Chart Precision Integrated Navigation System) software integration of any obsolescence solution within the WECDIS and WAIS equipment, as well as the maintenance of these systems, their technical support and the capability to provide training where required.

Accordingly, due to an absence of competition for technical reasons, the Contractor is considered as the only supplier that can provide the services and there are no reasonable alternatives to those services as required by the Authority.

The contract will not be awarded to an excluded or excludable supplier; a Contract Award Notice and Contract Details Notice will follow in accordance with Procurement Act 2023.
