...-pressure, ILI, gas distribution Abstract A large majority of urban gas distribution pipelines are designed to accommodate future integrity management surveys with in-line inspection (ILI) tools. However, even with typical inspection design parameters considered, many pipelines end up on a difficult...

...INCORPORATING INLINE INSPECTION INTERNAL MEASUREMENT UNIT DATA ANALYSIS INTO INTEGRITY MANAGEMENT PROGRAMS Doug Dewar1 Pembina Pipelines Inc. Calgary, AB. ABSTRACT Inline Inspection Internal Measurement Unit (ILI IMU) data analysis is a well understood but often under-utilized technology...

... of the six lines, 12 to 36 , have been inspected using the axial strain tool. The pipelines inspected cover a range of characteristics including, different vintages, pipe diameters and positions in the ROW. These differences, and the ILI runs provide an insight into the effect of a landslide event...

... methodology was applied to use data from multiple inline inspection (ILI) runs and field measurements with non-destructive examination (NDE) tools to increase confidence in crack size estimates. Multiple crack depth measurements were used in two different ways namely, to improve the characterization of ILI...

...CRACKS IN DENTS: HOW CAN I USE AN ILI ROBOT TO DETECT THEM? Rogelio Guajardo1, Dr. Thomas Hennig NDT Global GmbH & Co. KG Stutensee, Germany Carlota Mendez, Beatriz Tarramera NDT GDAC Spain SL Barcelona, Spain ABSTRACT Cracks in dents or linear anomalies interacting with dents are a major pipeline...

... and assessment of high density landslide areas at a system-wide scale, including the use of repeat LiDAR surveys (i.e., LiDAR Change Detection Analysis), in-line inspection (ILI) inertial measurement unit (IMU) data, aerial patrol/reconnaissance, and ground patrol. Case studies will be presented from...

... and the corrosion initiation time, and the probabilistic characteristics of the parameters involved in the growth model are evaluated using Markov Chain Monte Carlo (MCMC) simulation technique based on ILI data collected at different times for a given pipeline. The model accounts for the constant and non-constant...

..., preventative maintenance programs are employed to mitigate the SCC. Where required, Enbridge employs high-resolution crack in-line inspection (ILI) as the most precise method for managing SCC. As a member of the Canadian Energy Pipeline Association (CEPA), Enbridge participated in the development of a basic...
