Även med titeln: Comparison of ice load models for azimuthing thruster ice load calculation
The approach for the development of the ice class rules is to determine ice load scenarios and load cases to be included in the ice class rules. The ice loads will be calculated with sophisticated models and models will be verified with measurement data. Simplified load formulae will be developed based on ice load models and measurement data. The results will be combined to form the technical draft of Finnish-Swedish Ice Class Rules for azimuthing propulsion units. In this document, the work done during 2011 - 2012 is documented. The relevant load scenarios and applicable ice load calculation methods are presented, example cases selected and ice loads calculated for these example cases with different methods.
