Abstract: An insulating insert is positioned around a field joint of a pipeline to insulate the field joint. The insert has a longitudinal series of annular or part-annular filler segments of insulating material, curved about a longitudinal axis, that are each joined to one or more adjacent segments of the series by at least one link. The links may be webs, rods, or articulated links. The links are flexible relative to the segments to facilitate bending of the insert along its length by enabling relative angular displacement between adjacent segments of the series.

Abstract: A method and apparatus are for coating a field joint of a pipeline. The method includes positioning a mold tool around the field joint to define a mold cavity, positioning an insert to lie within the mold cavity, and injecting plastics material into the mold cavity to embed the insert in the plastics material. The apparatus has a mold tool positionable around the field joint to define a mold cavity, and an insert positionable within the mold cavity to be embedded in plastics material injected into the mold cavity. Use of an insert in this way reduces the volume of the molten thermoplastics material required to coat the field joint, thereby increasing the interface area of the melt relative to its volume, to the benefit of cooling time.

Abstract: The present invention concerns a method of retrofitting of a membrane electrolysis cell, wherein a rigid cathode is shaped by plastic deformation of the regions in correspondence of cathodic supports; a pre-shaped conductive elastic element having compressed regions in correspondence of said cathodic supports is overlaid onto said rigid cathode; a flexible planar cathode provided with a catalytic coating is overlaid onto said conductive elastic element. The invention also concerns a correspondingly retrofitted electrolysis cell.

Abstract: A method and apparatus are for coating a field joint of a pipeline. The method includes positioning a mould tool around the field joint to define a mould cavity, positioning an insert to lie within the mould cavity, and injecting plastics material into the mould cavity to embed the insert in the plastics material. The apparatus has a mould tool positionable around the field joint to define a mould cavity, and an insert positionable within the mould cavity to be embedded in plastics material injected into the mould cavity. Use of an insert in this way reduces the volume of the molten thermoplastics material required to coat the field joint, thereby increasing the interface area of the melt relative to its volume, to the benefit of cooling time.

Abstract: The invention is a system and a method for renting portable property, which can be a pre-purchase sample. The invention includes catering identification of an article onto the Internet. Receiving a plurality of requests via network from potential lessees to rent the article for requested rental periods then occurs. Sorting occurs for the requests to rent the article according to a chronology of the requested rental periods. Then, agreeing via network to rent the article to a plurality of lessees occurs. Transferring possession of the article from a lessor to a first lessee occurs such that the first lessee is the first in the chronology of the sorted, requested rental periods. Transferring sequentially the article between lessees according to the chronology of the sorted, requested rental periods is performed. Monitoring each rental and transfer of the article is done. Then, distributing a payment for each rental of the article occurs.

Abstract: A method of coating a field joint of a pipeline to accelerate the cycle time comprises positioning a mould tool around the field joint to define a mould cavity and injecting plastics material into the mould cavity through a plurality of gates in the mould tool, spaced along the mould cavity. The material is injected through different gates at different times as the mould cavity is filled, specifically through at least one first gate to advance a melt front within the mould cavity, and subsequently through at least one second gate spaced from the first gate, preferably when the melt front passes the second gate. First and second mould tools may be positioned successively around the field joint to create inner and outer coatings on the field joint. An insert may be positioned in the mould cavity to be embedded in the injected plastics material.

Abstract: An installation for manufacturing a wound rigid tubular pipe intended to be installed by a laying ship. An assembly unit for assembling a plurality of rigid tubes end to end to obtain lengths and for assembling the lengths to form the rigid tubular pipe which is intended to be wound onto a storage reel situated on the laying ship. An intermediate winding and deforming apparatus arranged on a first float distinct from the laying ship in order to plastically deform the rigid tubular pipe and wind it onto the intermediate winding apparatus after the rigid tubular pipe has been formed. A connector connecting together the first float and the assembly unit.

Abstract: A spacing and centering device for a rigid double-wall duct, for example of the winding type, which is intended for the transport of hydrocarbons. The rigid duct comprises two coaxial tubes which are separated by an annular space. The spacing and centering device is housed in the annular space in order to maintain a distance between the two coaxial tubes. An element made from a material having low heat conductivity and comprising an aerogel element is at least partially covered with a casing of polymer-type plastic material.
