APPARATUS FOR SUPPORTING PIPES SUSPENDED OVER UNDULATED SEA BEDS INCLUDING AT GREAT DEPTH

摘要

To form a support for a pipe (6), suspended over an undulating sea bed (2), there is used an apparatus having an inflatable cushion (28) releasably connected by a coupling (26) to a service module (9) which is lowered to the sea bed from a mother ship (7). The service module (9) has a container (11) filled with liquid cement. In use, the cushion (28) is positioned under the pipe (6), and is then inflated by liquid cement from the service module (9). The service module (9) is then released from the cushion (28), and the liquid cement in the cushion (28) sets so as to form a support for the pipe (6). IMAGE
