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.
