ABSTRACT:
Process and equipment for laying on the ocean floor a pipeline for the transfer of liquids or gas. In this process, the pipeline is constructed in a staging or shallow water area where the pipe is equipped with separate buoyancy and handling means, the conduit is submerged, towed to a location vertically above the pipeline route, the conduit is raised to the surface for inspection and preparation, one resumes in a controlled fashion and completes the submersion and positioning on the ocean floor, and finally the buoyancy and handling means are recovered. This process, due to its use of buoyancy and handling devices, considerably lowers the installation cost of underwater pipelines.
