L51827 Multiple In-Line Inspection Technologies

Combinations of technologies were evaluated by collecting and comparing information on the capabilities of different technologies and by evaluating the operational requirements of each. Results include; definition of important defect characteristics, determination of system constraints, evaluation of inspection technologies and determination of inspection technology capabilities and limitations, survey results of pipeline and in-line inspection companies, evaluation of inertial mapping and caliper capabilities and finally an evaluation of technology combinations. Based on the results, several examples of combinations of technologies were identified that may be sucessfully used to detect, locate the position of, and characterize different types of defects. The results of this study also identified what in-line inspection technology is best for particular circumstances and the conditions under which the technology would provide optimal results.
