Abstract: The present invention relates to an apparatus suitable for use in the automatic welding of pipes. The apparatus according to the invention comprises a fixed part or rail band which is clamped around the pipe at a prefixed position and a moving part which is driven with an orbital motion along the rail band and supports a swinging welding torch, a welding rod feeding mechanism and a torch position adjusting mechanism. The swinging motion of the welding torch is produced by a pneumatic system which permits both the amplitude and the frequency of said swinging motion to be adjusted. It is also possible to produce high swing frequencies and various times of stoppage for the torch at the ends of the swinging motion.

Abstract: This invention relates to an improved method for rapidly laying a pipeline in deep water by an anchored floating means. The rapid laying is obtained by varying the forces exerted by winches mounted on the floating means in such a manner as to impart a rapid movement to the floating means, in the longitudinal direction of laying, for a distance equal to the length of the piece of pipe added to the free end of the pipeline to be laid. Before termination of the rapid movement there is applied to the floating means a compensating force, whose direction, sense and intensity are such that, together with the forces exerted by the winches, said compensating force opposes moment by moment the central elastic force which induces a damped oscillatory motion in the floating means. This oscillation is thus eliminated or drastically and rapidly dampened.

Abstract: A method is disclosed for repairing a damaged pipe laid on deep sea beds, said method substantially comprising the step of joining a central pipe stub between the ends of the two adjoining pipe portions, such operation being performed directly on the sea bed rather than on the pipe-laying barge. Special coupling sleeves are provided at both ends of the central pipe stub, said sleeves being received in a watertight manner on the two pipe terminal portions, by clamping said sleeves thereon. Apparatus and tools for carrying out said method are described in great detail.
