To provide a marine vessel monitoring system capable of improving accuracy of collision risk evaluation.SOLUTION: A marine vessel monitoring system is provided comprising: a first data generation unit configured to generate first marine vessel data representing the position and speed of a first marine vessel; a second data generation unit configured to generate second marine vessel data representing the position and speed of a second marine vessel; a risk value computation unit configured to compute a risk value representing the risk of collision between the first marine vessel and the second marine vessel on the basis of the first marine vessel data and the second marine vessel data; a safety level determination unit configured to determine a safety level of the position of the second marine vessel from a distribution of the safety level determined with respect to the first marine vessel; a risk value adjustment unit configured to adjust the risk value according to the safety level; and an alarm unit configured to issue an alert when the adjusted risk value is greater than or equal to a threshold.SELECTED DRAWING: Figure 3

    【課題】衝突リスクの評価精度の向上を図ることが可能な船舶監視システムを提供する。【解決手段】船舶監視システムは、第1船舶の位置及び速度を表す第1船舶データを生成する第1データ生成部と、第2船舶の位置及び速度を表す第2船舶データを生成する第2データ生成部と、第1船舶データ及び第2船舶データに基づいて、第1船舶と第2船舶とが衝突するリスクを表すリスク値を算出するリスク値算出部と、第1船舶を基準に定まる安全度の分布から、第2船舶の位置の安全度を判定する安全度判定部と、安全度に応じてリスク値を調整するリスク値調整部と、調整されたリスク値が閾値以上である場合に、警報を発報する警報部と、を備える。【選択図】図3
