Abstract: An apparatus of reinforcing a hollow underwater member of an offshore platform which includes removable power-actuated motors, retaining means for preventing rotational movement of the motors relative to the retaining means while permitting axial movement of the motors, a drill and tap operatively connected to and driven by the motors for forming at least one port through a side wall of the hollow underwater member, and means operatively engageable with the motors for controlling the axial movement of the drill and tap in at least one direction during a port-forming operation.
