DEVELOPMENT OF CORROSION DATA SYSTEM FOR MARITIME STEEL STRUCTURES

A corrosion data system for maritime steel structures has been develop ed. This system is designed not only for retrieving the measured data of corrosion but also for analyzing large amounts of measured data to help derive corrosion mechanisms for steel in a marine environment. Th e system is based on RDBMS and is integrated with statistical analyzin g package, graph plot software and an image handling program. The grap hical user interface helps users to carry out complex query procedures easily. The data model using a classification of material data was em ployed and this data model has been effective for analyzing input data . The results obtained by the present system have included much new co rrosion information for maritime steel structures. Especially, if the exact environment factors were not measured, the data are estimated us ing a classified key word. In this point of view, the present system i s a very useful tool for corrosion science.
