A clamp engages an object such as a pipe at an undersea location and the clamp is connected by a wire to a surface station. At the upper end of the clamp is a mechanism for operating the clamp and this mechanism is provided with a seat for receiving a clamp arm of a manned submergible chamber. The manned submergible chamber grips the clamp mechanism and working in conjunction with the surface station closes the clamp on the pipe, and then after disengaging the work arm, the clamped pipe is brought to the surface station. The mechanism of this invention is particularly suited to offshore drilling operations as well as salvage operations. In another embodiment a hook is guided by the work arm to an object such as a pad eye and the hook engages the pad eye by the movement of the work arm. Once the pad eye is hooked the wire takes the hooked object to the surface.
