The supplier will propose methods used by other utilities and industries that could be developed and adopted as a recognised internal mains repair. The scope of the project is to research internal joint repair methods for the full range of metallic pipes and associated joints, targeted but not limited to diameters of 6” up to 24”, and for mains operating at Medium (>75mbar to <=2bar) and Low Pressure (<=75mbar). The identification of internal joint repair techniques identified during these work packages should minimise the number of excavations required to effect the repair. Limiting launch and recovery points of tools to keyhole cores or the ability to complete multiple internal joint repairs from one excavation is to be considered. The project will offer a down selection model of interim to permanent joint repair solutions. • Research available technologies applicable to internal pipe repair. • Down selection of most suitable solution(s) for each pipe repair scenario for further development and identify gaps in solution matrix. • Plan for progressing further development of each preferred solution.
