- Description
- In 2010 the Newcastle Port Corporation replaced a number of tubular mild steel piling after 33 years of service on the New South Wales Pacific Ocean coast due to heavy localized corrosion attack. Four of these tubular pilings were taken to the University of Newcastle for investigation. This paper reports on multiple longitudinal cross section loss measurements which allowed for statistical analysis of the variability of corrosion loss at different elevations. The statistical results are unique for such long-term exposures and are of major importance for structural reliability analyses of similar marine infrastructure assets. A pattern consistent with so-called accelerated low water corrosion was observed, suggesting microbiological attack at some point in time.
