PROBLEM TO BE SOLVED: To facilitate grasping/evaluation of total risk in navigation on the basis of a navigation plan.SOLUTION: A navigation support method is used including: a navigation planning step S12 for planning a navigation plan for a vessel; a plan navigation setting step S14 for carrying out the settings of the planned sea route on the basis of the planned navigation plan; risk analysis prediction steps S16 and S18 for deriving a collision risk value for the planned sea route on the basis of passing situation of other vessels throughout the whole process of the planned sea route and weather and marine phenomenon prediction information on the planned sea route; and a risk information providing step S20 for outputting risk information as the collision risk value derived in the risk analysis prediction steps S16 and S18.SELECTED DRAWING: Figure 4 【課題】航行計画に基づいて航行におけるリスクの全容を把握・評価することを容易にする。【解決手段】船舶の航行計画を立案する航行計画立案ステップＳ１２と、立案された航行計画に基づいて計画航路の設定を行う計画航路設定ステップＳ１４と、計画航路の全行程における他船舶の通航状況と計画航路上における気象・海象予測情報とに基づいて計画航路の衝突リスク値を求めるリスク解析予測ステップＳ１６，Ｓ１８と、リスク解析予測ステップＳ１６，Ｓ１８において求められた衝突リスク値をリスク情報として出力するリスク情報提供ステップＳ２０とを備える航行支援方法を用いる。【選択図】図４
