API Recommended Practice (RP) 1175 establishes a framework for Leak Detection Program (LDP) management for hazardous liquid pipelines that are jurisdictional to the U.S. Department of Transportation (specifically@ 49 CFR Part 195). This RP is an industry consensus document written by a representative group of hazardous liquid pipeline operators. API 1175 focuses on using a risk-based approach to each pipeline operator??s LDP. Reviewing the main body of this document and following the guidance set forth assists in creating an inherently risk mitigating LDP management system. API 1175 represents industry best practices in managing an LDP. All forms of leak detection used by a pipeline operator should be managed in a coordinated manner. The overall goal of the LDP is to detect leaks quickly and with certainty@ thus facilitating quicker shutdown and therefore minimizing negative consequences. This RP focuses on management of LDPs@ not the design of leak detection systems (LDSs)@ and therefore contains relatively little technical detail. As with API 1130@ API 1175 applies to single-phase pipelines only; however@ the approach may be applicable to pipelines that are not single phase.
