Conduit displacement mitigation apparatus including mesh layers, methods and systems for use with subsea conduits
Abstract:
Disclosed are apparatus, systems and methods for reducing displacement of a subsea conduit such as offshore hydrocarbon production pipeline, also referred to as pipeline walking or buckling, thus reducing the need for expensive pipeline anchoring or other mitigation solutions. A movement resistor adapted to be installed on a subsea conduit is provided having an inner portion adapted to receive and securely attach to a subsea conduit and at least one resistor portion adapted to resist induced forces. The at least one resistor portion includes a mesh layer therein that allows the passage of water but does not allow the passage of soil there through. At least one movement resistor can be installed along the length of a subsea conduit.
