To provide a draft management system capable of ensuring safety and of optimally maintaining fuel consumption in ship navigation.SOLUTION: A draft management system comprises a draft acquisition unit 50, a midship draft acquisition unit 50M, a GM calculation unit 10, a maritime phenomenon data acquisition unit 15, a maritime phenomenon determination unit 20 to determine a maritime phenomenon 6A, a GM curve setting unit 25 to set the GM curve on which the relationship between the GM value required for a safety navigation and the midship Dm is regulated, and a target draft setting unit 30 to set a target draft based on the GM curve. A maritime phenomenon determination criterion has a maritime phenomenon incremental criterion under which a ship 2 cannot safely navigate. The target draft is set to a safety draft on condition that the maritime phenomenon data 6A is determined to be greater than the maritime incremental criterion, and the target draft is set to the minimum value within a safely navigable draft range on condition that the maritime phenomenon data 6A is determined to be less than the maritime incremental criterion.SELECTED DRAWING: Figure 1
【課題】船舶の航行における安全性を確保すると共に、燃料消費量を最適に保つことができる喫水管理システムを提供する。【解決手段】喫水管理システムは、喫水取得部50と、船体中央喫水取得部50Mと、GM算出部10と、海象データ取得部15と、海象データ6Aを判定する海象判定部20と、安全航行に必要なGM値及び中央喫水Dmの関係を規定したGM曲線を設定するGM曲線設定部25と、GM曲線に基づき目標喫水を設定する目標喫水設定部30とを備える。海象判定基準は、船舶2が安全に航行できない海象荒れ基準を有し、海象データ6Aが海象荒れ基準以上と判定されることを条件に、目標喫水が安全喫水に設定され、海象データ6Aが海象荒れ基準を下回ると判定されることを条件に、目標喫水が、安全に航行できる喫水の範囲内で、最小値に設定される。【選択図】図1
