IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

NUMERICAL CASE STUDIES OF THE ICE LOADS TO AN AZIMUTHING THRUSTER DURING THE RIDGE INTERACTION
Author : Jaakko Heinonen, Juha Kurkela, Aki Kinnunen, Pekka Koskinen, Matti Jussila
An interaction between an azimuthing thruster and an ice ridge was simulated by the finite element method (FEM). An explicit solution algorithm was utilized, which enabled an efficient way to simulate ice failure in a dynamic analysis. The model described the whole ridge: the sail and keel consisting of ice rubble and the consolidated layer close to the waterline. The geometry of ridge was discretized by the finite elements. The azimuthing thruster including a part of ship body was modelled as a 3-dimensional rigid structure. The failure of rubble was modelled with a shear-cap material model. Spatially distributed
