This Guide provides requirements for the installation of, and the information to be provided by, Ice Loads Monitoring Systems fitted on ice-classed vessels. These systems are intended as an aid to the Master and navigating officers when a vessel is operating in ice infested waters so that appropriate action can be taken to minimize the likelihood of the vessel sustaining structural damage from interaction with the ice. The Ice Loads Monitoring Systems specified by this Guide extend from basic monitoring systems to sophisticated, integrated systems, the selection of which is left to the Owner. The information provided in the Guide is intended to assist the Owner in selecting the most appropriate system for a vessel based on the vessel’s probable operating parameters.The Guide describes the Ice Loads Monitoring process and the procedures for collecting, recording, processing, evaluating, and presenting the data in a manner that permits the Master and or navigating officer to better measure vessel performance in ice and determine if remedial action should be taken. The monitoring systems specified in the Guide can assist in identifying when the vessel is operating in ice in a manner that could lead to structural damage or failure by providing early warning to the navigator when the performance parameters relating to vessel strength are approaching the preset allowable levels.
