The components required for operational ice load monitoring systems for ice navigating ships are presented. Measurement instruments are outlined and maintenance free solutions discussed. Possible setups of the system architecture are given, including software and bridge displays. Integration with ice information and navigation displays is discussed. General solutions of operative monitoring are outlined. These reach from simple load level indication, assisting the navigating officer in decision making, to sea area oriented VTS monitoring of fleets. A method for load prediction, based on scale invariance of load statistics, is given. It can be used to generate predictions during short intervals. The relationships of ice load level to ice conditions and ship speed are studied within the approach. The determined of damage risk from load measurements is discussed. The research results on ice loads are in many respects not sufficient for real operative monitoring. Further research following the given methodologies given is suggested. The need of research cruises targeting to the open questions is stressed.
