... inspection (over the first 24 months at least) to confirm the impact of the changes on corrosion condition. In order to forestall a major increase in inspection requirements, it was decided to incorporate an on-line corrosion monitoring system into the vessels. The intention being for the monitoring system...

... no important corrosion events occurred; in the nineties however, seemingly without significant changes in operating parameters, corrosion conditions changed drastically. Several corrosion failures occurred on carbon steel tubing string at extremely high corrosion rate. Corrosion in surface facilities...
