Abstract

Propeller wake wash has been used effectively for ice management operations for years. The main uses of propeller wake wash include clearing pack ice and broken ice from offshore installations and shipping channels. A numerical model of a propeller wake has been developed to simulate the effect of the wake, or jet, on ice pieces floating on the water surface. The propeller jet was modeled using empirical equations derived from previous experiments. Model predictions are compared to experimental results of pack ice subjected to propeller wake wash. The analysis shows that this model can be used to simulate the clearing of pack ice. It has potential to be applied to model ice management operations.
