SYSTEMS AND METHODS FOR PROTECTING SUBSEA PIPELINE FROM EXCESSIVE STRESS OR FATIGUE LOADING |
| 摘要 |
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. |

1. A system for protecting subsea pipeline from excessive stress and/or fatigue loading, comprising:
a plurality of lifting buoyancy modules capable of being attached to a subsea pipeline in a normally non-activated state and having an activation mechanism associated there with; wherein the plurality of lifting buoyancy modules has sufficient buoyancy when at least a portion of the plurality of lifting buoyancy modules is activated to lift the subsea pipeline off the seabed to a predetermined height over a predetermined length. |
