ABSTRACT:
Sections of pipe for an underwater pipeline are laid by first positioning a support frame on the underwater terrain generally about the position for a section of pipe and then lowering a longitudinal pipe support and a section of pipe into engagement with the support frame. The position of the longitudinal pipe support on the support frame can be adjusted for proper positioning of the section of pipe with previously laid pipe. After a section of pipe is laid and supported by backfill, the underwater support frame is moved to the position for the next section of pipe. The support frame includes first and second transverse members each having a saddle for receiving a seat portion of the longitudinal pipe support. The saddles are moveable along the transverse members for adjusting the position of a section of pipe, and one of the transverse members is moveable. The longitudinal pipe support is moveable on a roller in the saddle on the fixed transverse member. The support frame includes a plurality of extendable vertical legs for engaging the underwater terrain.
