Beyond Unpiggable Inspections: Pipeline Attributes And Challenges To ILI Process

摘要

Today's inline inspection (ILI) technologies provide reliable solutions for inspecting pipelines once deemed unpiggable or difficult to inspect. Yet the tools are only one part of the solution. The fact remains that "unpiggable" pipeline challenges do not affect just the ILI tools -planning and managing the overall inspection project, and the complex variables involved, are critically important in delivering expectations in these challenging environments. In this article, case studies will reveal common pitfalls to avoid and how to improve ILI for unpiggable or challenging pipeline projects to increase success and optimize data quality.
