PROBLEM TO BE SOLVED: To provide an underwater work device and an underwater work method, which enable a hoisting load to be suspended and installed in a predetermined position and a predetermined direction in the water, while dispensing with work performed by underwater workers.SOLUTION: An underwater work device includes: a hanging frame 15 which is provided between a hoisting load 14 and a wire 13 extended from a crane 12, and which is moved integrally with the hoisting load 14 in the state of detachably holding the hoisting load 14; a sensor 17 for detecting a direction of the hanging frame 15; thrust generators 22a and 22b for turning the hanging frame 15 in the water; and a control unit 16 for controlling operations performed by the thrust generators 22a and 22b so that the direction of the hanging frame 15 measured by the sensor 17 can agree with a desired direction.SELECTED DRAWING: Figure 1

    【課題】水中作業員による作業を無くして、吊荷を吊り下げて水中の所定の位置及び向きに設置することができる、水中作業装置及び水中作業方法を提供する。【解決手段】クレーン12から延びるワイヤー13と吊荷14との間に設けられて、吊荷14を着脱自在に保持して吊荷14と一体に移動する吊枠15と、吊枠15の向きを検出するセンサ17と、水中において吊枠15を旋回させる推力発生器22a、22bと、センサ17が計測した吊枠15の向きを所望の方向に一致させるように推力発生器22a、22bによる動作を制御する制御装置16と、を設けた。【選択図】図1
