The objective of the SPIM-1-2 project was to identify and evaluate the most promising technologies for detecting and sizing fatigue cracks on heavy wall pipelines and risers, preferably without liquid coupling. To complete this evaluation, six…
Because where potentially serious damage is found it is dug and dealt with, models that assess damage severity have no relevance in that context. But, as in-line inspection tools become better adept in identifying and characterizing potential damage,…
Fatigue life prediction for in-service pipelines can vary considerably, with one of the prime sources of variability being the pipeline operating pressure data typically captured and archived using a Supervisor Control and Data Acquisition (SCADA)…
To assess the influence of line packing on the long term structural integrity of defected pipelines requires the availability of material property data that characterize the rate at which a flaw will extend under cyclic pressure conditions and the…

The objective of this study was to determine whether or not gas pipelines have a significant degree of exposure to failure from seam defects that could become enlarged by pressure-cycle-induced fatigue. If there is a potential problem in this…

A range of methods exist for assessing the remaining strength of a corroded pipeline under static pressure loading and these have now matured to the extent that they are incorporated in regulations and standards. However, there is currently no…
Research has been conducted to study the effects of dents, gouges, and weld seams on pipelines under cyclic internal pressure loading. The work associated with this project has involved both experimental and finite element analysis on pipes with D/t…
