Abstract : This project has studied a number of aspects concerning the reliability analysis of various marine structures and vessels. Our objectives have included the following: (1) To develop methodology sufficiently flexible to capture both long-and short-term behavior, which may be conveniently calibrated from environmental data available to the marine structural analyst and designer. (2) To reduce the computational expense of nonlinear stochastic analysis, which may become prohibitive for large numbers of response variables, by identifying more efficient analysis techniques. (3) To perform parametric studies of simple marine structures, to test feasibility of various methods and assess relative significance of various sources of nonlinearity and uncertainty (as well as correlation effects, e.g., between random wave, wind, and current in the same and different seastates).
