Instrumented pipeline corrosion inspection tools (IPCITs) can provide useful information about the integrity of a pipeline. There are many factors, however, that need to be considered in order to conduct a successful IPCIT survey. These factors include: 1) design of the pipeline and associated launching and receiving facilities, 2) requirements for auxiliary equipment such as pumping equipment, 3) running procedures, 4) operational procedures to ensure a safe survey, 5) log and defect verification procedures, and finally, 6) procedures for recommissioning the line. This paper discusses the operational experience that has been gained and the pipeline construction design practices that have been developed through 15 years of using the self-contained magnetic flux leakage type of IPCITs.
