A simple model for significant wave heights variability is proposed that features a relatively small number of parameters having very straightforward physical interpretation. The methods are applied to assessment of the expected damage accumulated in a vessel details as well as the variability of the damage. The Rice method is combined with the model to obtain prediction of the extreme seas that could be encountered by a ship. Significant wave heights are modeled by means of a spatial-temporal random Gaussian field. Its dependence structure can be localized by introduction of time and space dependent parameters in the spectrum. The model has the advantage of having a relatively small number of parameters. These parameters have natural physical interpretation and are statistically fitted to represent variability of observed significant wave heights records. The fitted spatial-temporal significant wave field allows for prediction of fatigue accumulation in ship details and of extreme responses encountered. The method is exemplified by analyzing a container ship data relevant for North Atlantic trade and the results show a high agreement with actual on-board measurements.
