MODELLING AND PREDICTION OF SEAWATER CORROSION OF STEEL STRUCTURES

Existing approaches to allow for corrosion of engineered structures are based on the concept of a constant corrosion rate, with order of magnitude estimates for the rates. Such rates are subject to much statistical uncertainty, largely due to (i) lack of data for actual structures as distinct from specimen corrosion samples, and (ii) the very large number of variables involved. The paper describes an attempt to develop phenomological probabilistic models of the corrosion of steel recognizing the above uncertainties and using the available data. The models have direct application in probabilistic assessments of service life for offshore structures. Both non-linear and bi-linear models are being explored.
