This paper presents the use of service life modeling to describe corrosion deterioration affecting an industrial marine structure in an aggressive environment. Measures taken to prevent and mitigate reinforcement corrosion were taken for the construction of basin and channel elements exposed to a stream of high-chloride concentration water. Furthermore, an impressed current cathodic prevention system was reportedly installed to prevent corrosion deterioration. Nevertheless, severe corrosion deterioration was observed in some structural elements after ten years in service. This study presents the use of service life modeling tools to estimate the initiation of reinforcement corrosion deterioration and predicted the long-term performance of elements 30 years after construction for various scenarios. Based on the modeling results, estimates of the time to corrosion initiation and corrosion propagation are elucidated and correlated with the premature corrosion deterioration.
