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.

Abstract: A retrievable module assembly can be used to install and/or de-install a blowout preventer (BOP) module from a BOP subsea where the BOP comprises one or more corresponding BOP module receivers. The retrievable module assembly typically comprises a frame configured to house and support the subsea BOP module; and a modular storage unit disposed at least partially within the frame. The modular storage unit further comprises a storage area configured to removably accept the subsea BOP module; a rotator configured to attach to and rotate the subsea BOP module, the rotator disposed at least partially within the frame; a rotator mover, slidably mounted in the frame and operatively in communication with the rotator; and a power connector operatively connected to the rotator and rotator mover and configured to interface with a power source.

Abstract: A device for capturing hydrocarbons discharged from a subsea flow passage comprises an elongate tubular structure having a central axis, a first end, and a second end opposite the first end. The second end is open and in fluid communication with the first end. The tubular structure includes a rigid stabbing member extending axially from the second end and configured to he inserted into the flow passage. In addition, the device comprises an annular flexible skirt disposed about the stabbing member. The skirt is secured to the stabbing member and extends radially outward from the stabbing member. The skirt is configured to flex from an unflexed position to a flexed position upon insertion of the stabbing member into the flow passage. The skirt is biased to the unflexed position and has an outer diameter in the unflexed position that is greater than the inner diameter of the flow passage.
