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.

Abstract: Disclosed are systems and methods for protecting subsea pipeline from damage caused by excessive stress or fatigue loading caused by geo-hazards, and environmental and operating loads. The systems and methods utilize lifting buoyancy modules capable of being attached to a section of subsea pipeline to lift the subsea pipeline off the seabed to a predetermined height over a predetermined length upon being activated by a planned or unplanned triggering event.

Abstract: Disclosed are methods, systems and computer readable storage media which facilitate the design of cables and pipes, including umbilicals, flexible pipes, optical cables, power cables, composite pipes, bundled pipes and combinations thereof. In one aspect, a computer implemented method includes, in response to input from a user in a plug-in interface in a graphical user interface within a computer-assisted design program, in a processor, executing instructions for receiving design information from a computer-assisted design program as well as receiving loading and deformation information from a global analysis software package for a cable or pipe having multiple components. A model is created using the design, loading and deformation information. The model is readable by a cable or pipe analysis software package. Thus the user is not required to manually generate the model of the cable or pipe readable by the cable or pipe analysis software package to be input into the cable or pipe analysis software package.
