... Abstract In the finite element analysis of dented pipes, an indenter is numerically pushed against the pipe wall to produce a dent profile measured from in-line inspection (ILI). The analysis is repeated until the differences between the calculated and measured profiles (i.e., depths) are less...

... Abstract The sizing performance of in-line inspection (ILI) tools are commonly illustrated on unity plots relating the ILI-reported size to a validation measurement, typically a non-destructive evaluation (NDE) field-measured height obtained using techniques expected to be more accurate than...

... Abstract Pipeline in-line inspection (ILI) stands out as an effective approach for comprehensively understanding the conditions of pipelines. Matching of corrosion features detected in multiset pipeline ILI is an essential prerequisite to determining corrosion growth. State-of-the-art methods...

... of its Integrity Management Program, TCE identified Selective Seam Weld Corrosion (SSWC) as one of the significant threats for certain seam weld types in their pipeline system. It also identified In-Line Inspection as the preferred methodology to address it. In that regard, multiple ILI vendors have...

... Abstract API Standard 1163 “In-Line Inspection System Qualification” sets the requirements for operators to define the scope of the inspection, its goal(s) and validate that a system has met the intent of the inspection. As part of the Integrity Management Program (IMP), an operator often faces...

... Abstract Pipeline operators have traditionally relied on unity plots from integrity digs and their confidence in the in-line inspection (ILI) tool vendor as a basis for trust in the results of ILI. However, past digs provide a narrow view of ILI success, and operators have limited visibility...

... Abstract NDT Global (ILI Service Provider) and Enbridge GTM (operator) have recently entered into an agreement to develop a new 30″ In-Line Inspection (ILI) system to detect, identify and characterize cracking in gas pipelines. The operator has invested resources over the years to manage...

... Abstract Crack (or crack-like) anomalies are a major threat to the safety and structural integrity of oil and gas transmission pipelines. Pipeline operators commonly manage the crack threat by hydrostatic test (HT) and in-line inspection (ILI) using electromagnetic acoustic transducer (EMAT...

... and Midstream (GTM), Houston, Texas, USA 2Stantec Inc, Houston, Texas, USA ABSTRACT In-line inspection (ILI) is a standard industry practice in managing the safety of buried transmission pipelines. It is important to develop a planning strategy for each ILI program to ensure pipeline safety while maintaining...

... Abstract Performing in-line inspection (ILI) run-to-run comparisons is a vital component of any pipeline integrity management program. A primary objective of ILI run-to-run comparisons is to establish corrosion growth rates along the length of a given pipeline segment that are defensible...

... Abstract The Probability of Exceedance (POE) methodology is used by pipeline operators to manage corrosion. It prioritizes anomalies identified by an in-line inspection (ILI) based on their likelihood of exceeding one or more failure thresholds. Two types of thresholds are commonly used: leak...

... Abstract Mechanical damage is a leading cause of serious pipeline incidents worldwide. Anomalies caused by it, including those associated with third-party damage, are challenging to detect, classify and size. In particular, in-line inspection (ILI) systems have had difficulty inspecting dent...

... Abstract Consecutive in-line inspections of transmission pipelines enable a comparison between the inspection results to characterize corrosion growth. Despite the high levels of in-line inspection tool accuracy and detection capabilities, corrosion defects with low calculated burst capacities...

.... In-line inspection tools both must detect mechanical damage and characterize parameters such as microstructure changes, residual stresses and extent of removed metal. These are the parameters that determine whether a defect is a candidate for delayed failure. Magnetic flux leakage (MFL) is commonly used...

... historical data was available for the 3 non-piggable pipelines compared to the newer 36 pipeline which was ultrasonically (UT) inspected via in-line inspection (ILI).
