One of the challenges in the pipeline industry is how to readily access accurate internal corrosion
data without numerous site visits. The remoteness of the numerous areas of concern adds to the
difficulty of monitoring the progress of the corrosion. One solution recently deployed by a fiber optic
company, combines a very sensitive non-intrusive fiber optic wall thickness sensor system with
networked monitoring instrumentation and a cell-based modem. This system allows remote tracking
of pipeline corrosion anywhere cell phone coverage is available.
