| Abstract | Northern Gas Networks (NGN) own and maintain more than 37,000 km of gas pipes and nearly 36,000 km of these operate at pressures below 7 bar. Each year NGN experiences a significant number of events of water ingress into low pressure gas distribution pipes. When water enters a gas network, a risk to consumers arises from water forming seals in undulating pipes; this often results in reports of poor pressure and interruptions to gas supply. Ingress into the network can occur through pipe joints and due to "third party" damage. In many cases, the location at which water naturally collects can be some distance from the point of water ingress. The movement of water through a gas distribution pipeline will be determined by several factors, including local pipe geometry and topography. This can make the precise location of water ingress extremely difficult and costly. Stage 1 of this project (1) looked at the incidence and causes of water ingress. This included the feasibility of using Geographic Information System (GIS) analysis, combining multiple data sources, to help identify the likely points of ingress, and water transport modelling to understand the movement of water through the gas network and to identify potential collection points. The objectives of Stage 2 are to further develop the work by taking the learnings from desktop studies in Stage 1 and to conduct field trials to demonstrate that they can be implemented. Other recommendations from Stage 1 and subsequent work on water ingress by NGN will be incorporated into new lines of investigation.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
