Environmental and operational uncertainties in long- term prediction of slamming loads of containerships

The purpose of the paper is to investigate long- term distribution of slamming loads of containerships accounting for different types of environmental and operational uncertainties. Following uncertainties are studied: the choice of the wave scatter diagram, the effect of the avoidance of heavy weather, the effect of the maneuvering in heavy weather and the uncertainty of the method for prediction of the long-term extreme slamming pressure. Long term distributions of bottom slamming pressures are computed using different combi-nations of the aforementioned uncertainties. The purpose of the study is the uncertainty assessment for the ap-plication in the reliability based design of ultra-large containerships.
