• Element three


    Visual inspection

    Metallic pipelines are typically made of iron or steel, which is susceptible to corrosion and cracking under stress.


    At the moment, if a distribution network wanted to measure the condition of a pipe asset, significant excavation works are required to expose the section of pipe to be surveyed. We need a technique which allows us to measures factors such as pipe wall loss and stress in a live gas environment.

    The project will develop a suite of sensors which will be mounted on the robotic transport platform developed during elements one and two.


    The sensor module will allow us to:

    • Assess the integrity of the mains pipe without turning gas off to customers

    • Minimise the costs and disruptions associated with excavations

    • Proactively identify locations where maintenance and repair will prevent future problems
