...Abstract Pipeline integrity management requires data integration to achieve the best assessment of pipeline condition. In the field of in-line inspection (ILI), data integration can be achieved correlating and merging the analysis results of data sets collected by tools (smart pigs) equipped...

...Abstract Oil and gas transmission pipelines are subject to internal and external agents that can cause corrosion affecting their safety, integrity, and profitability. Restoring pipelines to a safe operating condition is the main goal of inline inspection (ILI) using state-of-the-art Smart Pigs...

... damage to the ecology. Restoring pipelines to safe operating condition is the main goal of in-line inspection (ILI) using state-of-the-art Smart Pigs. These tools travel through the full length of pipelines gathering detailed information that is used for the assessment of both the internal...

... is the intelligent or smart pig. While there are various technologies offered by In line inspection (ILI) vendors, magnetic flux leakage (MFL) is the one most commonly utilized for in-line inspections of natural gas pipelines. Over the years there has been much speculation over the ability of an MFL tool to clearly...

... accuracy is ±0.2t if the width of the pit is greater than or equal to 2t. For generalized corrosion pitting, the minimum detection depth is 0.3t with a sizing accuracy of ±0.15t. This smart pig contractor has defined localized corrosion pitting to be less than three times the nominal pipe wall thickness...

...) ”intelligent” or “smart” pigs, hydrostatic testing, bellhole excavations to gain direct access for inspection of buried pipe and geographical information computer modeling to predict suspect areas are some of the methods being used by the gas industry. BACKGROUND Prior to the early 1980's, most research...
