The scope of work includes trials in a controlled yard environment of various technical solutions. The trial will involve deploying the solutions in the pipe and applying BAE.

The tasks to be covered include:

  • Task 1 - Ability to establish BAE / PRISM connection

  • Task 2 - Suitability of transition fittings

  • Task 3 - Emergency isolation

  • Task 4 - Repair fittings

  • Task 5 - Service Transfers

  • Task 6 – Reporting

  • BAE Rig to facilitate all of the above trials

The samples will then be inspected and tested by an independent consultant and a report issued detailing the findings and which solutions have successfully passed tests to proceed to a future trial combined with PRISM (Pipeline in Situ Manufacturing).

  • To demonstrate the ability to perform various connection scenarios, to include; BAE to PRISM, BAE to existing PE system and the suitability of transition fittings.
  • To demonstrate, and document repair and emergency isolation procedures and prove the suitability of the system.
  • To undertake pressure drop measurements across simulated transferred service prior to and following BAE application.
  • To collate preliminary safety documentation to ensure that all required data is available to take the project forward into live trials.
Satisfactory evidence to support the service replacement to main connection technique and results that enable us to continue to the next steps towards a commercial solution.

  • Technical report that demonstrates
    • Service Only Solution – The project must demonstrate an acceptable gas-tight solution to include:
      • Mechanical connection to the ECV

      • Mechanical connection at the footpath

      • Service pipe itself

    • Service to Main Solution - The project must demonstrate an acceptable gas-tight solution to include:
      • Mechanical connection to the ECV

      • Service pipe itself

      • Chemically bonded BAE connection to the PRISM main
