Objectives To scope requirements for systemTo further develop sensor to detect utility assetsTo develop prototype handheld unit to allow deployment of sensorTo develop GPR display and GIS output to allow comparative data to be gatheredTo carry out field trials of prototype handheld unit to gather dataTo compare results of handheld unit to existing GRP results Modelling Tool for Calculating Volumes of Water; Workshop/meeting with Network Analysis and MRP teams to establish requirements for a modelling tool and collect information regarding data availability; Based on the established requirements, develop a modelling tool that can be deployed on the ESRI ArcGIS platform and used by NGN staff; Demonstrate the modelling tool through a number of scenarios that, as far as possible, simulate previous water ingress events. 2. Likely Locations of Water Ingress/CollectionA series of GIS layers covering the entire NGN below 7 bar network. Data layers produced will be Compatible with ESRI ArcGIS and will show likely ingress locations and network low points. 3. Portable dew point moisture testingSuitable instruments will be identified and, working with Network Analysis, will be subjected to field trial. 4. Feasibility Study into Online Monitoring of Water Ingress; Assess the requirements for use and performance of hygrometers. Determine the feasibility of installation of moisture monitoring at above ground meter boxes, upstream of the meter. ; A technology search of available level indicators, hygrometers and associated equipment. ; Design, assemble and test a prototype set of equipment in the laboratory before being deployed in the field by NGN (under G23). ; Establish requirements for integrating data from moisture content measurements into existing NGN corporate data capture and reporting systems.
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
