Abstract

Icebreakers equipped with azimuth thrusters are becoming more common due to the tremendous operational benefits they provide. Despite the operational experience that exists, little is understood about the ability to break or clear ice using propeller wake. Naval architects who wish to design vessels to exploit this phenomenon currently have no verified methods of determining the effectiveness of their design decisions. Hence, it is extremely difficult to justify novel icebreaker design concepts where the mission profile includes breaking ice with propeller wake. This thesis explores the technical feasibility of using the panel method to model the hydrodynamic characteristics of the wake such that it could be applied to the problem of breaking and clearing ice using the wake from propellers. The scope of the research includes coupled vortex particle methods to overcome the difficulties encountered with panel methods.
