PROBLEM TO BE SOLVED: To provide a fixed point holding control device that continues to hold a work ship at a position, where work can be performed, without changing setting even when a movable part of a work machine mounted on the work ship is displaced with respect to a hull.SOLUTION: A fixed point holding control device 101 holds a work ship 100 to a fixed point. The work ship includes: a hull 10; a propulsion part 20 for moving the hull 10; and a work machine 30 having a movable part 31 that is movable with respect to the hull 10. The device includes: a target setting part 50 for setting a target work position; and a control part 60 that performs work position control to maintain the hull 10 so that an actual position of a reference point in a plan view is aligned with the target work position while using a predetermined part of the movable part 31 as the reference point.SELECTED DRAWING: Figure 1

    【課題】作業船に搭載された作業機械の可動部が船体に対して変位した場合であっても、設定を変更することなく、作業ができる位置に作業船を保持し続けることができる定点保持制御装置を提供する。【解決手段】本発明に係る定点保持制御装置101は、船体10と、船体10を移動させるための推進部20と、船体10に対して可動する可動部31を有する作業機械30と、を備えた作業船100を定点保持する定点保持制御装置であって、目標作業位置を設定する目標設定部50と、可動部31の所定個所を基準点とし、平面視において当該基準点の実際の位置が目標作業位置に一致するよう船体10を維持する作業位置制御を行う制御部60と、を備えている。【選択図】図1
