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.
