PROBLEM TO BE SOLVED: To provide a navigation support system for a vessel and a navigation support method for a vessel capable of suppressing navigation cost.SOLUTION: A navigation support system for a vessel includes: a constraining conditions setting unit for setting as constraining conditions, time required for navigation, vessel velocity relative to water for each section when a sea route is divided into a plurality of sections, inboard power demand of the vessel, output of the vessel, inboard accumulation batteries for every section and discharging amount and charging rate of the accumulation batteries, as well as temperature of the inboard accumulation battery and an accumulation device; an operation unit for carrying out optimization calculation under restriction conditions with the vessel velocity relative to water for each section as control variable, navigation cost from a first point to a second point as object function, and vessel velocity relative to water distribution for every section with the object function as minimum and a discharging amount of the inboard accumulation battery and the accumulation device as a solution. The navigation cost includes a cost regarding navigation of the vessel and a cost for charging and discharging of the accumulation device.SELECTED DRAWING: Figure 1
【課題】運航コストを抑制することが可能な船舶の運航支援システム及び船舶の運航支援方法を提供する。【解決手段】船舶の運航支援システムは、運航に要する時間、航路を複数の区間に分割した場合の区間ごとの対水船速、船舶の船内電力需要、船舶の出力、区間ごとの船内蓄電池及び蓄電装置の充放電量及び充電率、並びに船内蓄電池及び蓄電装置の温度を制約条件として設定する制約条件設定部と、制約条件のもとに、区間ごとの対水船速を制御変数とし、第1地点から第2地点に到着するまでの運航コストを目的関数として、目的関数を最小とする区間ごとの対水船速配分と船内蓄電池及び蓄電装置の充放電量を解として得る最適化計算を行う演算部と、を備え、運航コストは、船舶の航行に関するコストと、蓄電装置の充放電に関するコストとを含む。【選択図】図1
