| Research Abstract |
Recently, the risk-based approach, instead of traditional deterministic methods, becomes a powerful tool for safety assessment of ship and marine structures. In this study, elementary studies about risk assessment methods for ship and marine structures are carried out as follows : (1) A study on the risk-based assessment methods for ship and marine structures based on the remaining life benefit, (2) A study on the risk assessment methods based on system reliability approach, (3) Risk assessment and structural reliability analysis using commercial reliability software and non-linear finite element method, (4) Estimation of uncertainties of structural strength for structural reliability analysis. By these studies, availability of the risk-based approach for design and maintenance of marine and ship structures is discussed.
