ABSTRACT:
To connect two submerged conduits (e.g., a pipeline and a riser), a buffer unit is placed intermediate the two conduits. the buffer unit comprises an enclosure having a projecting conduit segment for attachment to each ofthe submerged conduits. An expansion mechanism is supported in the enclosure and interconnects the projecting conduit portions. The internal structure of the enclosure is such as to accommodate movement of the expansion mechanism (to accommodate, for example, thermal expansion or contraction of one of the submerged conduits), thereby isolating each of the submerged conduits from forces experienced by the other. Also disclosed are the use of positioning mechanisms to change the orientation of the expansion mechanism within the enclosure in order to change the position and/or orientation of the projecting conduit portions to facilitate coupling to the submerged conduits.
