Abstract
A pipeline comprises flow lines in which petroleum products flow and a protective carrier pipe around the flow lines. It further comprises a buoyancy module made of a thermally insulative material that is mechanically resistant to the hydrostatic pressure at the underwater site at which the pipeline is installed, the module providing the buoyancy required for installing the pipeline, in an economical manner.
Claims12
Underwater pipeline for transferring petroleum products comprising at least one flow line for such products a protective permeable carrier pipe around said flow line, a buoyancy module of a thermally insulative material mechanically resistant to the hydrostatic pressure at the underwater site at which the pipeline is installed, said buoyancy module being exposed, inside said carrier pipe, to a water pressure equal to the external hydrostatic pressure.
A pipeline according to claim l,wherein said carrier pipe is made from a material selected from the group comprising:
- PVC, a glassfibre reinforced plastics material.
