  • Patent number: 10442043
    Abstract: The invention provides a subsea torque tool (10) for a subsea vehicle system (such as an ROV), a drive head selection mechanism (30), and a method of use. The tool comprises a tool housing and a plurality of torque drive heads (22, 24, 26). The drive mechanism (17, 18, 20, 28) is operable to rotate the plurality of torque drive heads, and the drive head selection mechanism is used to select a drive head to impart a torque to a subsea device. The drive head selection mechanism comprises a rotary actuator (14, 32), and rotation of the rotary actuator effects axial movement of at least one of the plurality of drive heads between an operative position and an inoperative position. In another aspect, the drive head selection mechanism comprises an actuator operable from the exterior of the torque tool. In a preferred embodiment, the drive heads are sockets (22, 24, 26), and the selection mechanism comprises a rotary actuator and a cam mechanism.
