Development of Corrosion Data System for Maritime Steel Structures

A corrosion data system for maritime steel structures has been developed. 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. The system is based on RDBMS and is integrated with statistical analyzing package, graph plot software and an image handling program. The graphical user interface helps users to carry out complex query procedures easily. The data model using a classification of material data was employed and this data model has been effective for analyzing input data. The results obtained by the present system have included much new corrosion information for maritime steel structures. Especially, if the exact environment factors were not measured, the data are estimated using a classified key word. In this point of view, the present system is a very useful tool for corrosion science.
