Abstract: A process for regasifying a fluid and producing electrical energy includes subjecting a working fluid to 1) high-pressure pumping, 2) heating in a recovery unit to obtain a heated flow, the heating step comprising a low-temperature heat recovery step 2a) and a high-temperature heat recovery step 2b), 3) further heating to obtain a further heated flow, 4) expanding in a turbine, with production of electrical energy, to obtain an expanded flow, 5) cooling in a recovery unit by heat exchange, in a step 5a) with the flow of step 2b) and in a step 5b) with the flow of step 2a) to obtain a cooled flow, 6) expanding with production of mechanical energy, and 7) condensing the flow of working fluid. After step 5), a portion of the flow of working fluid is not subjected to step 6) and is subjected to a recompressing step.

Abstract: A method for laying a pipeline on the bed of a body of water comprises assembling a pipeline on a laying vessel; launching the pipeline from the laying vessel; identifying a zone of the bed of the body of water that causes stresses greater than a threshold value determined for the pipeline; progressively laying the pipeline on the bed of the body of water by advancing the laying vessel; and making, through controlled plastic deformation, at least one curved section along the pipeline with a curvature concordant with the curvature assumed by the pipeline in proximity to said zone, when the pipeline is at least partly laid on the bed of the body of water and partly suspended with respect to the bed of the body of water in proximity to said zone.

Abstract: A double liquid distribution device (1) suitable for use in in a fractionating or wash column (10) including a high collector tray (2) connected to a manifold support (7) via at least two longitudinal liquid downflow ducts (5, 6), the manifold support (7) supporting at least two series of transverse tubular manifolds (8, 8a 8b) and serving to feed liquid respectively to the first series of manifolds (8a) via a first longitudinal duct (5) and to the second series of manifolds (8b) via a second longitudinal duct (6), each manifold (8, 8a 8b) including distribution orifices (8c) in its under face that are suitable for distributing the liquid onto the top face of the packing bed (9). The two longitudinal liquid downflow ducts (5, 6) are connected together in a low portion (5b, 6b) by a communication device (11) fitted with a valve (12) having controlled opening that is suitable for allowing the liquid to be transferred between the two longitudinal ducts in a controlled manner.

Abstract: A coupling system (12) between a riser (2) and an underwater supporting structure (10), includes a coupling seat (13) and a coupling head (14) which can be inserted in the seat. A pull connector (16) constrains the head (14) to the seat (13) to prevent the extraction of the head (14) but to allow rotation of the head (14). A clamping connector (18) constrains the head (14) to the seat (13) to prevent transversal translation and rotation to the head (14) and the seat (13). The pull connector (16) can be actuated alone and independently from the clamping connector (18) to make a provisional, pull-only connection between the head (14) and the coupling seat (13). The clamping connector (18) can be actuated independently from the pull connector (16) to allow postponing the complete clamping with respect to the provisional connection.
