Study Group 4.1. Review of Asset Management strategies and practices The study will review the processes and methodologies used to develop strategies for operating, maintaining and replacing gas distribution networks. This will build on the Distribution Integrity study from the previous triennium. The study will recognize the influence of differing regulatory frameworks both in defining local good practice and assessing the applicability of “best” international practices. OBJECTIVES AND EXPECTED RESULTS Evaluate and make recommendations in the following areas: –The definition of distribution integrity performance measures; –The use of available information systems, data and the management of data quality; –The availability and applicability of cost/benefit calculations; –The influence of national and international technical standards; –The influence of economic regulation and competitive markets; –The range of approaches within legal frameworks; prescriptive vs risk-based. –Reactive > Time-based > Condition > Risk-based prioritisation.

Study Group 4.2 Review of Leakage Reduction strategies & practices. The study will determine the process necessary for the evaluation and determination of leading practices used in the industry for the management of leakage from gas distribution systems. These leading practices will be based on reviewing commonly defined metrics of operational performance. Methane is a significant greenhouse gas and leakage is perceived to contribute to depletion of the ozone layer. Leakage also presents safety, economic and operational challenges to distribution operators. OBJECTIVES AND EXPECTED RESULTS The study will provide: –A review of leakage management strategies across member countries; –Assessment of the ability to quantify leakage from distribution systems; –Specific focus on the effectiveness of leakage survey methodologies; –Identification of best practices in leakage management systems; –Review of existing and emerging technologies for leakage control.

Study Group 4.3. Development of best practices for the prevention of third party interference damage to distribution assets. This is a study to evaluate how each of the IGU member countries approach the management of third party interference damage to gas distribution systems. This emerged as a major integrity issue from the triennium study. It is important to determine the various approaches, funding levels, legal requirements and collaborative efforts currently in place. OBJECTIVES AND EXPECTED RESULTS The study will provide a review of damage control activities associated with gas distribution systems including: –Provision of plant records & information to enable location; –Legal/regulatory requirements driving plant location; –Measures of effectiveness of plant protection systems; –Resourcing requirements for site attendance where provided; –Review of existing and emerging technologies for damage control; –Identification of best practices in plant and damage location systems across all utilities.
