To provide an automatic hull-attitude control method capable of improving safety and accuracy of cargo handling works, and capable of reducing work loads of crews.SOLUTION: An automatic hull-attitude control method establishes a ballast water arrangement plan depending on a current loading condition and on a new loading condition at the time of a cargo handling for a small coastal tanker, remotely operates a fluid cargo valve (an original side fluid cargo valve 12, an end side fluid cargo valve 13), a cargo pump 11, a ballast valve 22, and a ballast pump 21 on the basis of the ballast water arrangement plan, and starts cargo handling works. The automatic hull-attitude control method predicts a draft and a hull inclination of a small coastal tanker 1 based on a liquid level of a cargo tank 10 and a ballast tank 20, and changes a flow rate ratio of the ballast tank 20 and the cargo tank 10 when the predicted hull inclination exceeds a predetermined permissible range.SELECTED DRAWING: Figure 1
【課題】荷役作業の安全性、正確性を向上させ、また船員の労務負荷を軽減すること。【解決手段】小型内航タンカーの荷役時には、現載貨状態と新載貨状態によりバラスト水配置計画を策定し、バラスト水配置計画に基づき、貨物弁（元側貨物弁１２、末端側貨物弁１３）、貨物ポンプ１１、バラスト弁２２、バラストポンプ２１を遠隔操作して荷役作業を開始する。貨物タンク１０及びバラストタンク２０の液面高さに基づいて、小型内航タンカー１の喫水と船体傾斜を予想し、予想された船体傾斜が、予め定められた許容範囲を超えている場合には、バラストタンク２０と貨物タンク１０との流量比率を変更する。【選択図】 図１
