Abstract
An apparatus for deploying an underwater pipe string includes a mast, an articulated table, a stinger, and a pipe erector. The mast is affixed to the articulated table and extends above the articulated table. The stinger is affixed to the articulated table and depends below the articulated table. The pipe erector is connected to the mast for loading pipe joints up to the mast. A pipe joint loaded in the mast is welded to the pipe string, which depends from the articulated table and through the stinger toward a seabed. The stationary table is articulated for tilting of the table, the mast, and the stinger azimuthally and angularly for a preferred direction and lay angle of the pipe string being deployed.
