Title:
GM CALCULATION SYSTEM, METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2020032744
Kind Code:
A
Abstract:
To provide a system for calculating a GM accurately in real time without the need for complicated data processing using measurement data of existing sensors without separately providing sensors.SOLUTION: A GM calculation system 1 comprises hull state detection means, rolling period detection means, representative rolling period identification means, and GM calculation means, where the hull state detection means detects the hull state amount using a draft gauge installed on the hull in time series, the rolling period detection means continuously detects the rolling period of the hull on the basis of the hull state amount detected in time series by the hull state detection means, the representative rolling period identification means identifies the representative rolling period of the hull in a specified period on the basis of the rolling period in the specified period detected by the rolling period detection means, and the GM calculation means calculates the GM value of the hull on the basis of the representative rolling period identified by the representative rolling period identification means.SELECTED DRAWING: Figure 3
