ABSTRACT:
A subsea machine tool for preparing the end of a bare piece of pipe in a subsea location for receiving an overfitting coupling and includes a support assembly adapted for raising and lowering in a body of water. A pipe clamp is attached to each end of the support assembly for clamping the pipe. A split frame is supported by the support assembly for axial travel. A split ring gear assembly is supported by the frame for rotation therein and about the pipe section. The split ring gear is in the form of a spool assembly wherein an involute gear forms one flange of the spool and a face plate forms the other flange. The spool is supported about the exterior thereof by a split fixed ring which in turn is supported by the frame. The fixed ring has mounted thereon one or more hydraulic motors which are arranged for rotating the ring gear relative to the fixed ring. The face plate has mounted thereon for rotation therewith work means in the form of a milling machine. Another tool is mounted on the face plate for sensing out-of-roundness of the pipe and the concentricity of the pipe relative to the ring gear, and for providing a read-out of any variations in roundness or concentricity, which read-out may then be used to operate the milling machine to remove the discontinuity.
