    Abstract: Improvements in or relating to underwater pipe-layingA 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: A system for levelling and gripping a jacket leg into a hollow foundation pile has a levelling assembly (14) for adjusting the longitudinal axis (A) of a jacket leg (8) partially inserted in a hollow foundation pile (11) with an actuation group (26) arranged about the jacket leg (8) and configured to exert a force parallel to the longitudinal axis (A) between the upper edge of the hollow foundation pile (11) and the jacket leg (8) and selectively attachable to the jacket leg (8) and recoverable for further use in another levelling assembly (14); and a gripping assembly (13) for locking the jacket leg (8) in a given position with respect to the hollow foundation pile (11) once leveled.

    Abstract: The present invention relates to a process for regasifying a fluid and producing electrical energy, wherein a flow of a working fluid is subjected to the steps of: 1) high-pressure pumping, 2) heating in a recovery unit, thus obtaining a heated flow, said step comprising a low-temperature heat recovery step 2a) and a high-temperature heat recovery step 2b), 3) further heating, thus obtaining a further heated flow, 4) expanding in a turbine, with production of electrical energy, thus obtaining 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), thus obtaining a cooled flow, 6) expanding with the production of mechanical energy, 7) condensing said flow of the working fluid, wherein, after step 5), a portion of the flow of said working fluid is not subjected to step 6) and is subjected to a recompressing step.
