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.

近年来，基于风险的方法取代了传统的确定性方法，成为船舶和海洋结构物安全评估的有力工具。本文对船舶和海洋结构物风险评估方法进行了初步研究：(1)基于剩余寿命效益的船舶和海洋结构物风险评估方法研究；(2)基于系统可靠性方法的风险评估方法研究；(3)基于商用可靠性软件和非线性有限元方法的风险评估和结构可靠性分析；(4)结构可靠性分析中结构强度的不确定性估计。通过这些研究，讨论了基于风险的方法在海洋和船舶结构设计和维护中的可行性。
