ABSTRACT:
A method and system for connecting the ends of a pair of tubular conduits for use at the bottom of a body of water in which terminal portions of said conduits, adjacent to and including said ends, are buoyantly supported in a generally elevated attitude within the body of water with the ends in a zone of the body of water below the surface thereof. The ends are positively fixed against movement relative to each other but permitted limited movement, as a unit, relative to the bottom of the body of water. The connection of the conduit ends is made within the aforementioned zone of the body of water.
