Objectif A collaborative ECSC project has shown that severe corrosion of steel piling structures at the low-water level in tidal waters is principally caused by microbially induced corrosion (MIC). Steel piling walls on quays, harbours, jetties, etc, are having to be replaced after as little as 20 years and this is leading to a loss of confidence and a potential loss of market. Although it was clearly essential to establish the cause of this problem, steel end-users are only concerned with methods of prevention. This project is therefore concerned with:. development of methods of assessing the risk of excessive low-water corrosion at any specific site;. testing of possible methods of protection against MIC at the low-water level.A coordinated research programme has been assembled which will involve: . Sampling and characterisation of biofilms and corrosion products from selected locations, leading to identification of the key microbial species;. Statistical analysis leading to a predictive model of risk; . Cathodic protection in MIC conditions;. Protective coatings, including biodegradability;. Use of alloy steels in MIC conditions;. Use of high pressure water cleansing;. Methods of protecting existing structures.
