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.

In embodiments, a hot tap clamping system comprises a clamp which fits over and secures against a pipe, an actuator interface, an actuator operatively in communication with clamp, and a hot tap assembly. In a further embodiment, a system for sealing a flowline with a metal seal after hot tapping comprises a sealer, a hot tap drill/plug running tool, and a metal seal plug which is typically configured for use in sealing a flowline, e.g. a pipe, with a metal seal after hot tapping where the metal plug seal is inserted into the pipe and engages with and seals as a hot tap.
