... Numerical simulations are carried out to examine the interaction of a managed ice cover with a drillship. Station keeping is maintained using a mooring system and Thruster-Assisted Mooring. The ice model is based on solving the momentum and constitutive equations, which determine the stresses...

... for in the model. The ice cover is driven by prescribed displacements or pressures at the boundaries. Wind and water current drag are also included. The simulations address cases of ship moving at constant velocity through a uniform ice cover, of 200 m width and 1 km length. The geometry of the Canadian Coast...

... is ice-covered nine months of the year. Ice engineering work involved the planning, surveying and monitoring of a 7.5 km long ice road and the construction and monitoring of an ice platform in the middle of the lake.
