To provide a position retaining system capable of retaining a position of a linear object.SOLUTION: A position retaining system (100) for retaining a position of a linear object (1) lowered into water from a vessel (14) includes: one or more propelling devices (2) each including a body unit (20) fixedly attached to the linear object (1), a plurality of propellers (15) for generating thrust, and a transponder (3); a power device (8) for supplying power to the plurality of propellers (15); a controller (9) for controlling thrust of the plurality of propellers (15); a receiver (10) for receiving sound waves from the one or more transponders (3); a position detector (11) for detecting relative positions of the propelling devices (2) to the vessel (14); and a satellite positioning system (12) for detecting a present position of the vessel (14). The controller (9) controls the thrust of the plurality of propellers (15) based on the present positions of the propulsion devices (2).SELECTED DRAWING: Figure 1

    【課題】線状物体の位置を保持することを可能とする位置保持システムを提供する。【解決手段】船(14)から水中に降ろされた線状物体(1)の位置を保持するための位置保持システム(100)は、線状物体(1)に固定的に取り付けられた本体部(20)と、推力を発生する複数の推進器(15)と、トランスポンダ(3)と、を備えた、一以上の推進装置(2)と、複数の推進器(15)に動力を供給する動力装置(8)と、複数の推進器(15)の推力を制御する制御装置(9)と、トランスポンダ(3)からの音波を受信する受信器(10)と、船(14)に対する推進装置(2)の相対位置を検出する位置検出装置(11)と、船(14)の現在位置を検出する衛星測位システム(12)と、を備える。制御装置(9)は、推進装置(2)の現在位置に基づいて、複数の推進器(15)の推力を制御する。【選択図】図1
