Abstract: A pipeline closing head, for use in testing a pipeline after it has been laid on a submerged bed by subjecting the pipeline temporarily to internal pressure through the use of filling and emptying balls, is constituted by a hollow cylindrical body having a crowned closing element at one end and containing, at its other end, an air tight chamber housing the filling and emptying balls. Ducts and control valves through which fluid is supplied to said chamber to activate the filling and emptying balls and supply fluid pressure to the interior of the pipeline are housed within the cylindrical body so that they do not overhang the closing head, which may slide along a conventional ramp for the pipeline.

Abstract: Apparatus for laying a pipeline of large diameter on a deep sea-bed without kinking or excessive bending includes a floating vessel having a discharge track sloping downwardly toward the stern to support the outer end of a pipeline for sliding movement and mechanism for imparting tension to a pipeline is mounted on the discharge track. A stinger, adapted to slidingly support a pipeline as it is being laid, is pivotably connected to the discharge end of the track and is formed from articulated ramp segments, each buoyantly supported independently of the others so that its depth in the water may be regulated, whereby the stinger may be caused to extend downwardly from the stern of the vessel along a predetermined slope.

Abstract: Apparatus for supporting pipe suspended over depressions in the sea bed and method of, comprising a service modular unit capable of being completely recovered and another modular unit intended for properly supporting the pipe: the two modular units are so connected that they can be disjointed under a command from the pipe-laying barge. The service modular unit is equipped with a recoverable assembly for placing the supporting modular unit in a correct vertical posture on the sea bed and for vertically holding such supporting modular until the pile-driving operation has been satisfactory completed.

Abstract: An apparatus or "coupler" for use in welding two lengths of pipe to be butt-welded, particularly suitable for welding a section of pipe to the end of a pipeline section being laid on the sea bottom, comprising an elongate body having a first portion and a second portion, which can be attached to respective pipes by means of respective attachment means and sliding means cooperating with the attachment means in order to move the first and second pipes towards each other, whereby, during the welding, not only the two pipes on internally changed to the said portions with their axes aligned, but are also drawn and held together, even when one of the pipes undergoes a longitudinal reciprocating movement.

Abstract: For lifting from deep sea beds a pipeline trunk, a device is disclosed which is composed by a compact framework of square outline which supports a sealing and pulling head and paired jaw assemblies having sloping surface seats to engage the outer surface of the pipe to be lifted, said jaws being actuated by hydraulic and pneumatic motive means so as to grip the pipe surface firmly. A pipe-cutting device is also provided, which has two discrete cutting units, and the sealing and pulling head is removable from said frame and can be both slid and rotated as to position it correctly coaxially with the pipe trunk.
