Begin Directed Inspection and Maintenance (DI&M) at Remote Facilities. |
| Text: |
Table 1â€"Cost-Effective Options for Reducing Methane Emissions: "Begin Directed Inspection and Maintenance (DI&M) at Remote Facilities. Fluctuations in pressure, temperature, and mechanical stresses on pipeline components (such as valves and seals) eventually cause them to leak. A DI&M program concentrates on components such as valve packing, pneumatic controllers, open-ended lines, blowdown (sic) lines, pneumatic engine-starter motors, and pressure-relief valves, which are prone to large leaks that are cost-effective to find and fix. A survey is conducted in the first year of a DI&M program to identify leaking components. In subsequent years, inspection and repair efforts are focused on components that are the most likely to leak and most cost-effective to repair. Partner companies report that leak surveys cost U.S. $200 per station when multiple remote stations are surveyed at one time."

| Cost-Benefit Analysis: |
Cost & Benefits:
Equipment Cost = N/A;
O&M Cost = $1 per component screened;
Saleable Gas Saving (Mcf/d) = 1.0;
Expected Payback = N/A;
Operating Requirement = Soap solution and/or Gas Detector;
Basis for cost saving = Screening 200 components, repair leaks
in one open-ended blowdown valve and one control valve
stem seal;
Other Benefits = N/A
