... The objective of this paper is to report progress and recent findings related to the remediation of damaged high-pressure, high-temperature (HPHT) flowlines in deep water. The flowline repair technology currently being developed utilizes an R&D process of systematically identifying...

... is to use two "structural" leak clamps to make spool piece repairs, or use one of the two to clamp a pinhole leak. The use of the same clamp design for either application avoids needing multiple tools. For flowline repair, the recommendation is to cut the flowline on bottom, lift the ends to the surface...
