To improve accuracy in ballast adjustment while carrying out other cargo handling work.SOLUTION: A vessel control system 1 includes: a flow meter 30 for measuring flow rate of ballast water flowing through piping 90; an actuator 40 for operating a valve 50 that is connected to the piping 90 and adjusts the flow rate of the ballast water; and a valve control substrate 20. The valve control substrate 20: determines, based on a preset planned flow rate of the ballast water or a measured flow rate of the ballast water measured by the flow meter, whether there is any need to control the valve 50; and, upon determining that it is necessary to carry out control of the valve 50, calculates a target opening of the valve 50 based on the planned flow rate, the measured flow rate, and a present opening of the valve. The actuator 40 operates the valve 50 so that the target opening is obtained.SELECTED DRAWING: Figure 3
【課題】他の荷役作業を行いつつ、バラスト調整の精度を向上させること。【解決手段】船舶制御システム1は、配管90内を流通するバラスト水の流量を測定する流量計30と、配管90に接続されバラスト水の流量を調整するバルブ50を操作するアクチュエータ40と、バルブ制御基板20と、を備えている。バルブ制御基板20は、設定されたバラスト水の計画流量、及び流量計で測定されたバラスト水の測定流量に基づき、バルブ50の制御を行う必要があるかどうかを判断し、バルブ50の制御を行う必要があると判断した場合、計画流量、測定流量、及びバルブの現在の開度に基づき、バルブ50の目標開度を算出する。アクチュエータ40は、目標開度になるようにバルブ50を操作する。【選択図】図3
