Abstract:
A system and method for securely cradling a subsea pipeline is claimed that lands on one side of the pipeline, is embedded into the sea floor, reaches under the pipeline, positions the cradling structure, and then lifts the pipeline. The system typically comprises a gravity driven pile based device, comprising a pile tower, a roller carriage assembly, and a jacking assembly that engages the roller carriage assembly and pile tower rails.
