On Board Test of Hull Strength Monitoring System

This paper describes summarized results of on board test of hull strength monitoring system which is currently being developed by Nippon Kaiji Kyokai. The purpose of installing this system on board of ships is to provide the navigator with supplementary informations on hull response to wind and waves in heavy weather and to monitor hull response during cargo loading or unloading, ballasting or deballasting operation so that the ship master can make an appropriate judgement for ship operation and maneuvers. A brief discussion is made on the results of the test where hull response data is analyzed from view point of studying correlations among various responses of the ships.
