Title:
SHIP WAKE REDUCTION ASSISTANCE DEVICE, PROGRAM, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/210366
Kind Code:
A1
Abstract:
The present device is a ship wake reduction assistance device 2 installed on a ship. The present device comprises: an input interface 4 that acquires information on the ship, and information on another ship 24 or an offshore structure around the ship; and a calculator 8 to which the information is input from the input interface 4 or a pre-memory device 6. On the basis of the input information, the calculator 8 predicts wave height, at the position of the other ship 24 or the offshore structure, of the ship wake generated when the ship sails on a current course and at a current speed, assesses whether or not the predicted wave height exceeds an allowable value, determines a changed course or changed speed when the allowable value is exceeded, and outputs information on the changed course or changed speed.
