- Description
- For the assessment of the long-term structural reliability and serviceability of infrastructure it is desirable to have available good quality models for predicting future deterioration such as corrosion. The development of such models is described briefly, noting that microbiological as well as physicochemical processes are involved. These required adequate, preferably science based models to be developed, drawing on a range of disciplines. They have shown that the data required often lies well outside that normally considered for assessment of infrastructure. Recent applications include corrosion of steel piling in harbours, mooring chains for FPSOs anchored in seawaters up to 3 km deep, cast iron bridge piers for historic railway bridges, and the external corrosion of buried cast iron water mains found in all major cities. It is argued that pollution by the nutrients necessary for microbiological activity is a major threat to the service life of ferrous infrastructure.
