| Summary: | This paper presents an investigation of the zone of broken ice around the Molikpaq during interaction with moving ice. The width of this zone may have direct implications with respect to safe evacuation of personnel. A two-dimensional numerical model was used to study the size and behaviour of the broken ice zones with level ice interacting with both the long and short sides of the Molikpaq. Several scenarios of ice interaction with the Molikpaq were investigated. The results show the influence of ice thickness, ice velocity and approach angle of the ice upon sail height and rubble extent. A review of field observations obtained during operation of the Molikpaq shows that the model well predicts the zone of broken ice. The model can be used to evaluate emerge ncy evacuation systems for different structure shapes and ice conditions. NRC publication: Yes |
