The course introduces students in modern physical and mathematical models describing physical environmental loads on coastal and offshore structures in the Arctic.
The course includes descriptions of physical mechanisms of the environmental loads on the structures by waves, ice and sea currents and explain methods of the construction of corresponded mathematical models.
The main focus is on the models describing ice crushing and piling up near narrow and wide structures, acceleration of floes and icebergs by surface waves, wave actions on fixed and floating structures, tide and thermally induced ice stresses, seabed gouging by ice keels, ice piling up on the beach, seabed erosion by under ice currents, abrasion of steel and concrete surfaces by the ice, bearing capacity of the ice under static and moving loads. Lectures also include formulation of codes for the design of offshore constructions in ice conditions and probability methods for the estimates of risks due to long term exploitation of offshore structures.
Seminars include analytical exercises and numerical simulations by Comsol Multiphysics. Laboratory work include experiments on the behaviour of ice samples under non-stationary loading, bending and indentation tests in the ice tank, experiments on ice permeability, experiments on ice interaction with steel and concrete surface. Measurements of floating quay movements induced by water actions with synchronous measurements of sea currents, tides and waves is planned as field work in Longyearbyen harbour.
