The Extremes of Combinations of Environmental Loads

Document Type: Proceeding Paper

Part of: Structural Safety and Reliability


The objectives and the general approach of an offshore environmental data and extremal analysis are described. The intention is to develop long-term design values of wave, wind and current processes which, together, generate extreme load effects in offshore structures. The analysis procedure is to take into account factors such as nonstationarity, auto- and crosscorrelation, nonlinearities and uncertainties in the load modeling, and arbitrary combinations of processes. A preliminary data inspection shows which analysis features and techniques are appropriate.
