ABSTRACT:
An improved method and apparatus for coupling together conduit sections to form a pipeline while submerged in a fluid medium. During the operation of laying the pipeline while submerged in a fluid meduim, such as the ocean, adjacent pipe sections to be joined are subjected to a reduction in internal fluid pressure with a pump or the like so that during the joining operation, the pressure inside the adjacent pipe sections is lower than the exterior fluid pressure causing the pipes to readily come together and seat properly.
