Abstract: A mobile pipe handling frame useful for building and repairing subsea pipelines is disclosed and includes a vertically adjustable beam and horizontally adjustable sled thereon which may be utilized for suspending a hydraulic pipe clamp for grasping and moving pipe sections vertically and horizontally. The sled and beam may also be utilized for supporting and positioning one end of a stabber beam which, with its other end resting upon the pipeline, may be utilized to telescope tubular coupling members onto the end of the pipeline. The pipe handling frame and hydraulic pipe clamp also may be used to "walk" a pipe section, or one end of a pipeline, across the ocean floor transversely to the longitudinal axis of the pipeline. A method for utilizing the pipe handling frame, hydraulic pipe clamp and stabber beam for repairing damaged subsea pipelines and for completing subsea pipeline connections to risers are disclosed.
