Corrosion monitoring in remote or hostile locations

Examines two aspects of a new system being installed by BP engineering. First, the measurement of corrosion in hot, dangerous and inaccessible locations, both within process plants and on remote pipelines and, second, the automatic collection of data from widely separated measurement points at a single location for monitoring and assessment. Discusses recent advances in ultrasonic non‐destructive test instruments and low frequency electro‐magnetic communication techniques, showing how these have made this project possible.
