Loads due to First Year Ice Ridges on a Vertical Cylinder

This paper presents some predictions of ice ridge loads on a vertical cylinder, based on model experiments, analytical methods, and numerical simulations. The experiment program involved the interaction of a vertical cylinder with two unconsolidated ice ridges. Each ridge was nominally 1.9 m wide with a keel 0.5 m deep. The nominal scale used for the experiment was 1:30. The analytical methods included Dolgopolov, Mellor, Croasdale & Cammaert, and ISO19906. The numerical simulations were carried out using a discrete element computer code, named DECICE. The paper compared the results of model experiments, analytical methods and numerical simulations.
