Probability Based Ship Design; Loads and Load Combinations

Abstract

Several aspects of loads and load combinations for reliability based ship design are investigated. These include identification of relevant hull girder and local loads, load calculation models, procedures for extreme loads and load combinations, treatment of combined load effects for fatigue, and modeling errors related to loads, response and structural analysis. Impact of operational factors such as heavy weather countermeasures on design loads is discussed. Load combination procedures of two levels of complexity are provided: (a) those suitable for design use, and (b) more elaborate ones for detailed analysis. Among the procedures are a new design oriented probabilistic load combination factor method for steady state wave induced load effects, and a time domain method suitable for combining vertical wave induced bending and transient slam effects.
