To provide a working method using an AUV (Autonomous Underwater Vehicle) capable of navigating the AUV with accuracy toward the vicinity of a work interruption position of a work object from a return destination.SOLUTION: A working method using an AUV includes the steps of: working on a work object with a work device included in the AUV while navigating the AUV along the work object; throwing down a transponder and sinking it to the water bottom; navigating the AUV toward a return destination; and navigating the AUV to the vicinity of a work interruption position where a work is interrupted regarding the work object from the return destination on the basis of information obtained from acoustic positioning using the transponder sunk to the water bottom and restarting the work regarding the work object.SELECTED DRAWING: Figure 1

    【課題】帰還先から作業対象物の作業中断位置近傍に向けて精度良くAUVを航走させることができる、AUVを用いた作業方法を提供する。【解決手段】AUVを用いた作業方法は、AUVを作業対象物に沿って航走させながら、AUVが有する作業装置で作業対象物について作業するステップと、トランスポンダを投下して水底に沈めるステップと、AUVを帰還先に向けて航走させるステップと、水底に沈めたトランスポンダを利用した音響測位により得られた情報に基づいて、AUVを帰還先から、作業対象物についての作業を中断した作業中断位置の近傍まで航走させ、作業対象物についての作業を再開するステップと、を有する。【選択図】図1
