PROBLEM TO BE SOLVED: To provide a towing management method and system for a towed body by which a tow boat can accurately tow the towed body even when a tide and a wind change in a towing water area, and even if the towed body is a large-sized structure such as a caisson.SOLUTION: A towing management method for a towed body acquires data on a flow direction and a flow rate of a tidal current in an area where a towed body is towed, predicts a towed route of the towed body based on a preset towing route and the data on a flow direction and a flow rate S03, determines whether or not the predicted towed route of the towed body is in a range of a preset condition S04, changes a towing route of a tow boat when it is determined as being out of the range of the preset condition, predicts the towed route of the towed body again S03, and determines the towing route of the tow boat by repeating the prediction until it falls within the range of the preset condition S05.
【課題】曳航水域において潮流や風などが変化した場合でも、また被曳航体がケーソンなどの大型構造物の場合であっても曳船が被曳航体を正確に曳航することができる被曳航体の曳航管理方法およびシステムを提供する。【解決手段】この被曳航体の曳航管理方法は、被曳航体が曳航される区域の潮流の流向・流速のデータを取得し、予め設定された曳航ルートおよび流向流速のデータに基づいて被曳航体の被曳航ルートを予測しS03、予測された被曳航体の被曳航ルートが予め設定した条件の範囲内であるか否かを判断しS04、設定条件範囲外と判断された場合、曳船の曳航ルートを変更し、被曳航体の被曳航ルートを再び予測しS03、この予測を設定条件範囲内に収まるまで繰り返すことで曳船の曳航ルートを決定するS05。【選択図】図6
