To provide a sailing route calculation technology capable of determining an appropriate sailing route even if a control mode is changed.SOLUTION: A sailing route calculation system 10 includes a mode acquisition part for acquiring a current control mode from a control device of a main engine 74 which operates in any mode in a plurality of modes including a first control mode for processing difference between a target moving speed of a ship 1 and an actual moving speed of the ship 1 or difference between a target rotation speed of the main engine 74 and an actual rotation speed of the main engine 74 with a first algorithm, and determining first control information showing a fuel supply amount or fuel supply timing to the main engine 74, and a second control mode for processing the difference with a second algorithm different from the first algorithm and determining second control information, an information acquisition part for acquiring the current position, a destination, a departure time and a target arrival time of the ship 1, and a sailing route determination part for determining a shipping schedule of the ship 1 on the basis of the current position, the destination, the departure time, the target arrival time, and the current control mode.SELECTED DRAWING: Figure 1

    【課題】制御モードが切り替わっても、適切な航路を決定できる航路計算技術を提供することを目的とする。【解決手段】航路計算システム10は、船舶1の目標移動速度と船舶1の実移動速度との差分、又は、主機74の目標回転速度と主機74の実回転速度との差分、を第1アルゴリズムで処理し、主機74への燃料投入量又は燃料投入タイミングを示す第1制御情報を決定する第1制御モードと、差分を第1アルゴリズムと異なる第2アルゴリズムで処理し、第2制御情報を決定する第2制御モードと、を含む複数のモードの内のいずれかのモードで動作する主機74制御装置から現在の制御モードを取得するモード取得部と、船舶1の現在地、目的地、出発時刻、及び目標到達時刻を取得する情報取得部と、現在地、目的地、出発時刻、目標到達時刻、及び、現在の制御モードに基づいて、船舶1の運航計画を決定する航路決定部と、を備える。【選択図】図1
