This article is mainly based on the characteristics of marine environment islands and coastal seas current corrosion problems storage tanks as well their main locations, analyse reasons for formation consider potential safety hazards, so to propose several effective tank protection methods, which has important positive significance long-term development oil tanks.

the main objective of this article is evaluation of the simplified models which have been developed for analysis and design of liquid storage tanks. the empirical formulas of these models for predicting maximum sloshing wave height (mswh) are obtained from mass spring models (msm). a finite element modeling (fem) tool is used for investigating the behavior the some selected liquid storage tanks...
