Abstract: A pipe support frame for positioning a subsea pipeline. The support frame includes lower and upper skids which are maintained in vertical alignment with one another. The lower skid includes vertical lower skid members and the upper skid includes mating vertical upper skid members which slidably engage the vertical lower skid members and maintain vertical alignment. Water jacking bags are positioned between the upper and lower skids to alter the elevation of the upper skid. The upper skid includes a pair of parallel beams. A trolley assembly is movably mounted to the pair of parallel beams to adjust the lateral position of the pipeline. A saddle for receiving the pipeline is attached to the trolley assembly. A threaded drive rod is rotatably mounted between the pair of parallel beams. The threaded drive rod is threadably engaged with the trolley assembly such that the lateral position of the trolley assembly is controllable by manipulating the threaded drive rod.

Abstract: A pipe attachment and receiving apparatus for severing and handling a subsea pipe. The apparatus including a chassis adapted to mount onto a subsea pipe and clamps for clamping the chassis to the subsea pipe. An interface assembly is connected to the chassis. The interface assembly is adapted to extend and retract relative to the chassis. The interface assembly is adapted to receive modules. The modules are adapted to be releasably mounted to the interface assembly. A cutting module is mounted to the interface assembly to cut the pipeline and a docking module is mounted to the interface assembly to repair the pipeline with a replacement spool.

Abstract: A method for repairing a damaged subsea pipeline setting on the seabed includes the lowering of pipe support frames to the seabed and positioning the pipe support frames beneath the subsea pipeline on each side of the damaged pipeline section. The pipe support frames are expanded to elevate the damaged pipeline section. A pair of pipe attachment and receiving (PAR) assemblies are lowered to the seabed and positioned astride the pipeline on each side of the damaged section of the pipeline. The pipeline is gripped by the PAR assemblies. Cutting modules are lowered to the seabed and attached to each of the PAR assemblies. The pipeline is cut at each location with the cutting modules. The cutting modules are detached from the PAR assembly and a pair of docking modules are lowered to the seabed. One docking module is attached to each of the PAR assemblies. A telescoping spool section is lowered to the seabed and docked onto the docking modules.
