Objectives The objectives of this project are to: Quantify the heat losses associated with at least 8 SGN sites; a range in heating systems, location, pressures etc. Develop a decision tool to determine whether lagging is required. Improve philosophies to overcome false indications of preheat asset failures and reduce call outs in response to low station exit temperature alarms. The success criteria for this project is to seek evidence how to optimise our alarm, control and operating philosophies to increase energy efficiency, reduce unnecessary call outs and potentially eliminate the requirement for lagging. The project will be determined to be a success if the following is achieved: Quantified heat losses associated with a range of sites. Develop software/excel spreadsheet with user guide for lagging decision support tool. Revision of existing SGN policy documentation with corporation of findings. Completed technical report on results, findings and comparisons between new and existing elements. Provide technical report on detailing fault reduction benefit option for SGN to optimise the alarm, control and operation philosophies and how the analysis can be used across the network. Share the learning of this project with the other Network Licensees.
Abstract The Immersion tube pre-heating project at Lochmaben (NIA_SGN0002) identified heat losses associated with the system that could be rectified and efficiency of the system improved, thus removing unnecessary call outs to site. Many of our sites have preheating systems installed to manage the Joule-Thoms On effect from pressure reduction. There are a significant number of alarms and faults associated with preheating control systems. If we can optimise our control systems we hope to be able to eliminate unnecessary callouts and increase reliability and efficiency of these systems. The most common call out related to heat loss of preheat is heavily influenced by the flow conditions and where the sensor is located. The strategic heat study will provide an improved methodology based on factors including sensor location, the present of lagging and other heat losses would result in a reduction in call outs. Significant corrosion has been identified under lagging. Inspection of pipework under lagging presents a greater challenge than other inspection activity due to the need to remove and replace. Ideally the pipelines would not require lagging and primary protection through standard coating systems would suffice. The majority of PRSs have a low pressure change across the site and operate at ambient temperature therefore lagging will not be required. SGN specification for thermal insulation of above ground pipework and equipment (SGN/SP/PWC/2) states pipework containing pre heated gas over 10oC should be lagged. To understand if the lagging is required we need to understand the heat losses associated with the system. A heat loss study will be conducted for 8 sites which quantify the heat losses associated at each site. Using the results from the strategic heat study a decision tool will be developed which will determine if the process can still work without lagging and quantify the heat loss with or without lagging as a percentage of the yearly consumption. Quantified heat losses associated with a range of sites. Gather 100% useable data from at least 8 SGN sites. The analysis can be applied to the remaining network. Gap analysis and risk assessment and gap analysis of relevant industry and SGN standards and specifications. Develop software/excel spreadsheet for lagging decision support tool. The tool will determine the heat losses associated with or without lagging as a yearly percentage consumption. Revision of existing SGN policy documentation with corporation of findings. Completed technical report on results, findings and comparisons between new and existing elements. Provide technical report on detailing fault reduction benefit option for SGN to optimise the alarm, control and operation philosophies and how the analysis can be used across the network.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
