To enhance the ECDA process, this project evaluated whether soil data could be used in a model to predict locations where external corrosion would be an issue. If by adding soils data to the previously collected ECDA datasets it could be shown that…
Develops a quantitative assessment of time-dependent threats, with a focus on vintage onshore gas transmission pipelines. Characteristics for the vintage pipeline system were established in terms of diameter, wall thickness, service conditions, grade…
The objectives of this research are to figure out how solid state decouplers (SSDs) influence the surveys related to pipeline cathodic protection (CP) and provide corresponding field guidelines on how to mitigate the adverse effects of…
A protocol developed is to help assure that the Pipeline Research Council International ECDA-ILI Demonstration Project (Project) receives the correct and sufficient data to successfully conduct the analyses and meet the Project objectives. Its focus…
This presents the results of applying an existing method (Structural Reliability Analysis) and software to compare the integrity of five pipelines. The work involves analyzing data from both ECDA and ILI and comparing the reliability levels achieved…
The purpose of integrity assessments of gas transmission or liquids pipelines is to minimize hazards to the general public, minimize pipeline leaks and spills, ensure continuous operations of the pipelines, optimize expenditures for reducing risk,…
This report covers the evaluation and analyses of ten ECDA projects conducted by nine natural gas pipeline operators. The objective of this work was validation of the ECDA methods proposed in NACE RP 0502 as an integrity assessment method that could…
This study evaluated the effectiveness of ECDA as an inspection methodology and integrity assessment process. This was performed through a series of steps including the following:
- Developing and sending out questionnaires to a broad array…
This project involved a series of activities and field studies to evaluate the ECDA process and techniques in the presence of dynamic stray currents. The overall project objective was to verify that ECDA could be effectively applied and is a viable…
The purpose of this project is to compare the attributes of three pipeline integrity assessment methods: direct assessment, hydrostatic testing, and in-line inspection.
Technical Perspective:
In conjunction with on-going work by others to…
