SHIP NAVIGATION CONTROL SYSTEM AND SHIP NAVIGATION METHOD

PROBLEM TO BE SOLVED: To reduce the noise and strain of a hull, to improve the comfort in the hull, and ensure the navigation safety of a ship since vibrations that may cause various troubles to the hull can be reduced.SOLUTION: A ship navigation control system comprises: a hull-state detection sensor 2 provided in a hull of a ship for detecting a vibration or a strain of the ship or a noise in the hull; a hull-state determination unit 3 configured to determine whether a hull state index based on a detection result of the hull-state detection sensor 2 deviates from a specified range; and a navigation control unit 4 configured to control ship equipment to change a navigation state of the ship including at least one of a speed, an attitude, and an orientation of the ship so as to reduce the vibration or the strain of the hull or the noise in the hull on the basis of a determination result of the hull state determination unit. 【課題】船体に対し各種不具合を招く原因となる振動を低減できるため、船体の騒音や歪みを低減し、船体内の快適性を向上すると共に、船舶における運航の安全性を確保する。【解決手段】船舶の船体に設けられ、船体の振動若しくは歪み又は船体内の騒音を検出するための船体状態検出センサ２と、船体状態検出センサの検出結果に基づく船体状態指標が規定範囲を逸脱したか否かを判定するように構成された船体状態判定部３と、船体状態判定部の判定結果に基づいて、船体の振動若しくは歪み又は船体内の騒音が低減されるように、船舶の速度、姿勢又は方位の少なくとも一つを含む船舶の航行状態を変化させるために船舶の機器を制御するように構成された航行制御部４と、を備えた。【選択図】図１
