System and method for coupling of a bottom based pipeline to an adjacent riser pipe or another pipeline, of the kind wherein is utilized a bottom based coupling frame. The underside of the frame (,) is designed in order to undergo displaceable movements along the sea bottom or on a fundament thereon both during and subsequent to coupling of the pipelines to the frame. On the frame are mounted coupling members for one importing and one exporting pipeline, and a pipe connection between the pipe couplings, optionally including a valve and other equipment. In accordance with the method, a tool including a winch and a pulling wire, is mounted on the frame whereby the frame, including the pipeline, can be pulled together in order to accomplish the coupling operations.
