Title:
VESSEL OPERATION ASSISTANCE APPARATUS AND VESSEL OPERATION ASSISTANCE PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/004362
Kind Code:
A1
Abstract:
Provided are a vessel operation assistance apparatus and a vessel operation assistance program that are capable of improving the accuracy in estimating a hull motion index and/or an evaluation index in an assumed route. An exemplary vessel operation assistance apparatus according to the present invention is provided with: a resistance increase characteristic storage unit that stores, in a storage medium (M6), resistance increase characteristic information in irregular waves, which enables the value of a resistance increase caused by waves under respective vessel hydrographic conditions to be derived; a resistance increase characteristic changing unit (16) that calculates the value of a resistance increase caused by waves during a real operation on the basis of data relating to hull resistance measured during a real operation of a vessel, and changes the resistance increase characteristic information so that the value of a resistance increase, caused by waves under a hydrographic condition corresponding to hydrographic data of the real operation time based on the resistance increase characteristic information, becomes equal to the value of the resistance increase caused by waves during the real operation; and an evaluation index estimation unit that estimates an evaluation index for an assumed route on which the vessel sails, on the basis of a hydrographic forecast on the assumed route and the resistance increase characteristic information which has been changed by the resistance increase characteristic changing unit (16).
