ABSTRACT:
A method and apparatus for laterally maneuvering the ends of pipes supported on the seabed under a body of water. The method includes mounting a first support frame adjacent to one of the pipe ends and supporting the first frame on the seabottom. A connecting means is secured between the pipe and the first support frame and thereafter the adjacent pipe is raised by applying a lifting force to the connecting means. A second separate support frame is mounted adjacent to the other of said pipes and with the second frame being supported on the seabottom. Another connecting means is secured between the other pipe and the second support member and the other pipe is raised by applying a lifting force to the other connecting means. Thereafter, with both pipe ends thus supported in cantilevered fashion, the pipe ends are moved laterally and vertically relative to the support frame until the pipe ends are brought into positions where the axes thereof generally intersect.
