The approach for the development of Finnish-Swedish ice class rules for azimuthing thruster 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 full scale measurement data from ice breaker Fennica. Simplified load formulae will be developed based on advanced 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 up to and including 2014 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.
