Title:
HYDROGRAPHIC PHENOMENA ESTIMATION APPARATUS AND HYDROGRAPHIC PHENOMENA ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/086482
Kind Code:
A1
Abstract:
The present invention is provided with: a record storing means for storing a record of ship body movement data; a ship body status data calculation means for calculating a current ship body status data of a ship on the basis of the record of ship body movement data stored via the record storing means; a cross-spectrum calculation means for calculating the cross-spectrum of respective ship body movement of rolling, pitching and vertical swing on the basis of the record of ship body movement data; a ship body response function calculation means for calculating a ship body response function on the basis of the ship body status data; and hydrographic phenomena estimation means for estimating hydrographic conditions in a sea area through which the ship body is cruising on the basis of the cross-spectrum of the respective ship body movement and the ship body response function.
