Pipeline Integrity Assessment and Management

Abstract

Pipeline integrity assessment and management (PIAM) is a process that ensures that pipelines operate safely. This article discusses assessments that are primarily based on in-line inspection (ILI) tools. The early development of these tools dates back to the mid-1970s. There are other types of assessment methods such as pressure (hydrostatic) testing and direct assessment that play a part. There has been a significant shift of focus on PIAM over the past several years because of a few recent catastrophic pipeline failures and greatly improved ILI technology, both of which allow for the detection of potential failures. NACE International Standard RP0102 outlines a recommended practice for conducting an ILL Finally, four case histories are presented based on ILI and pressure testing.
