ILIVS DA VS HYDRO -WHAT ASSESSMENT TO UTILIZE? (PPT)

摘要

1 No single pipeline integrity inspection method is currently capable of identifying or addressing all risks of concern that can result in pipeline 2 Identifying threats that need to be assessed is critical for all of the assessment methodologies. 3 History of the line is an important part of any assessment. 4 Root cause analysis of any failures is critical in determining the correct subsequent assessment. 5 A DA structured process should be considered as a possible role model tor addressing integrity concerns with distribution gas pipelines A structured process, similar to the DA process, would be highly efficient and effective in dealing with gas distribution infrastructure. 6 It is important to note, as discussed in a study conducted by Kiefner and Associates for the INGAA Foundation, a "well-maintained and periodically assessed pipeline can transport natural gas indefinitely." 1
