Abstract: A method of welding together the ends of outer pipe sections (16A, 16B) of pipe-in-pipe pipeline to be laid on a seabed employs an annular member (5) interposed between adjacent lengths of pipe. The annular member comprises a first axial part (11) which fits within the end of the first outer pipe section, and a flange part (12) which is interposed between the adjacent ends of the two lengths of outer pipe sections (16A, 16B) to be joined. The flange part (12) of the annular member (5) projectsradially outwardly beyond the inside of the outer pipe sections (16A, 16B) and terminates radially inwardly of the outside of the outer pipe sections (16A, 16B), and provides some of the welding material for the joint.

Abstract: The invention concerns a welding device and a welding method, in particular of tubular parts (c1, c2) such as abutting metal conduits to form pipeline metal pipes, which consists in effecting the penetrating pass from outside. The invention is characterized in that it consists in creating a single liquid weld metal under the simultaneous action of at least one laser beam (1) transmitted by optical fiber and at least one electric arc protected by gas generated from a consumable electrode (2a) constituting the filler material. The invention is mainly applicable to the construction of pipelines.

Abstract: Remote-controlled joining system for subsea pipelines for joining two smooth pipeline ends (pipe ends) that are arranged facing in line a distance apart, with means arranged to move at least one of the pipeline ends sideways and in the longitudinal direction. The joining system is distinguished by comprising: a pipe sleeve having internal seals against each pipeline surface, for insertion of pipe ends to facing position within the seals, and a welding clamp with integrated welding tool for remotely welding of a first end of the pipe sleeve to the first pipeline and a second end of the pipe sleeve to the second pipeline, the welding clamp can be remotely fastened sealingly around the pipe ends and the sleeve and is equipped with means for establishing and maintaining a welding atmosphere in a volume delimited by the seals of the clamp and the seals of the sleeve.

Abstract: A welding apparatus, for welding pipe sections (1, 2) together to form an underwater pipeline, is arranged to weld pipe sections (1, 2) together when they are in a generally upright orientation with the bottom of an upper pipe section (2) abutting the top of a lower pipe section (1) that defines the end of a pipeline. The welding apparatus includes a rotary equipment holder (5) mounted for rotation about a generally vertical axis (8) and having a central opening (5A) through which pipe sections (1, 2) are able to pass as a pipeline is laid, a plurality of welding heads (12) angularly spaced about the rotary equipment holder (5), each head (12) being associated with a respective sector of the rotary equipment holder, and a welding head guide assembly (11) for fixing around a pipe section (1). The guide assembly (11) includes a guide track (14) for guiding movement of each of the welding heads (12) around the pipe section (1). The respective sector of the rotary equipment holder (5) is able to revolve around the pipe section (1) as the associated welding head (12) revolves around the pipe section (1).

Abstract: The present invention is a method and a vehicle-mounted apparatus (30) for laying pipelines in which adjacent pipe (17, 28) are joined by the technique of magnetically impelled arc butt welding (MIAB). A MIAB welding head (13) having a welding axis is mounted on a transportable platform (35). A pipe guide (50) capable of engaging a welded pipe string is located rearwardly of the welding head (45). The pipe guide (50) maintains alignment of the string with the welding axis. The apparatus includes pipe feed means (47, 48, 49) maintaining alignment of a next pipe to be laid with the welding axis and the pipe string (17). The platform (37) is rotatably mounted on the vehicle (30) and tilts around a horizontal axis. The vehicle (300) is provided with pivoting steerable tracks (38).
