Under an Integrity Management Program (IMP) for natural gas transmission lines, the ECDA concept was analyzed and the process was validated from 2002 to 2004. A Plan was developed and implemented in 2004 on one 17 km pipeline and segments of two other pipelines. This paper covers the Request for Proposal (RFP) methodology, the selection of a service provider, the execution plan and the results obtained.
