Inspection—A Smart Investment?

The inspection and maintenance of pipelines will help to extend the low probability of the pipeline failure curve with a "bath tub" shap, which can reduce pipeline failures. Some inspection and monitoring methods have been set forth according to different pipeline damages. With these methods, the risk assessment of pipelines can be made, including a corroding pipeline assessment and pipeline damage assessment. It describes the problems of in-line inspection to be considered and the costs, and highlights the importance of using genuine high-resolution pigs for the inspection, the cost savings on the optimised future safe operating strategies for the pipeline offset costs of the inspection and expert assessment.
