PROBLEM TO BE SOLVED: To provide a vessel speed control device and the like which enable a ship to navigate in accordance with a shipping schedule with improved fuel consumption.SOLUTION: A vessel speed control device controls a vessel speed of an electric propulsion ship navigating according to a shipping schedule in which the ship navigates a route of a predetermined distance for a predetermined period of time. The device comprises: a zone division part S1 for dividing the predetermined time period into a plurality of zones; a propulsion power consumption calculation part S3 for calculating propulsion power consumption for each zone; an appliance power consumption calculation part S4 for calculating appliance power consumption for each zone; a vessel speed selection part S6 for selecting a vessel speed which exhibits the best fuel consumption of a power generator for each zone based on the propulsion power consumption and the appliance power consumption; and a vessel speed reset part for resetting the vessel speed for each zone which is selected by the vessel speed selection part. When the navigation distance of the ship which navigated for the predetermined period of time at the vessel speed for each zone selected by the vessel speed selection part does not match with the predetermined distance, the vessel speed reset part resets the vessel speed of the zone with the smallest fluctuation of the fuel consumption.

    【課題】より良い燃費で運航計画に従った航行を行うことができる船速制御装置等を提供する。【解決手段】所定距離の航路を所定時間で航行する運航計画に従って航行する電気推進船の船速制御を行う船速制御装置は、所定時間を複数のゾーンに分割するゾーン分割部S1と、ゾーン毎に推進消費電力を算出する推進消費電力算出部S3と、ゾーン毎に機器消費電力を算出する機器消費電力算出部S4と、推進消費電力及び機器消費電力に基づいて、ゾーン毎に発電機の燃費が最も良い船速を選定する船速選定部S6と、船速選定部により選定されたゾーン毎の船速を再設定する船速再設定部とを備え、船速再設定部は、船速選定部により選定されたゾーン毎の船速で所定時間を航行した場合の航行距離が所定距離と一致しないとき、燃費の変動が最も小さいゾーンの船速を再設定する。【選択図】図9
