HULL MOTION MONITORING DEVICE WITH HULL OSCILLATION PREDICTING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a hull motion monitoring device with hull oscillation predicting function, for which weather and marine forecast values are taken into consideration. ;SOLUTION: A data monitoring device 3 to monitor data for the motion of a hull in a fixed time from an oscillation meter 1 and a heave meter 2, a weather and marine predicting treatment device 4 to collect weather and marine forecast values in a time zone for prediction, a prediction processor 5 to analyze accumulated data for the motion of the hull, calculate a model formula for uniquely determining the motion of the hull, overlap with a wave spectrum found from the weather and marine forecast values in a time zone for prediction and find prediction peak values for oscillation and heave in a time zone for prediction and an alarm judgement device 6 are provided. The alarm judgement device 6 outputs an alarm when the prediction peak values exceed alarm reference values to support the launching of a helicopter on board and safe ship operation.;COPYRIGHT: (C)1999,JPO
