Project Zero aims to develop a number of encapsulation technology prototypes to enable zero interruption to customers gas supplies during a number of network operations.
The project will aim to development a replacement method in the four key areas outlined below.

1.Live Exchange of ECV’s (TRL4 – 7)

2.Use of ServiceCam to be used on steel services (TRL5-7) (No ECV).

3.Live Service Isolation Valve exchange or insertion on to a service (TRL4-7)

     o  Fitment of isolation valve to Metallic Pipe work (TRL4-7)

     o Isolation approach for PE pipework diameter (TRL4-7)

4.Live Pivot Tee exchange (TRL4-7) for emergency situations
