报告摘要:

The specification of long-term design loads for offshore structures considering multiple environmental factors is investigated where the dependency between several commonly used sea state parameters are instituted through a copula-based multivariate probabilistic model. Several copula functions, capable of modelling both linear and non-linear dependence structures, are considered. The developed multivariate copula model is compared with the available approaches in the literature using actual environmental data. The modeled sea state parameters are utilized to characterize the sea load for the reliability analysis of a real jacket structure where the prediction of the long term load is derived in a discretized form.
