摘要： An arrangement of an umbilical of data communication lines and/or electrical energy transmission lines is mounted on a lazy wave catenary riser. The umbilical has a first section extending from an upper hang off location of the riser continuously downward to a first installation point at the riser and a second section extending from a second installation point at the riser continuously downward to the sea bed at a riser touch down location. The first installation point is positioned in an installation region of the riser between a lowest sag bend point and a highest hog bend point of the lazy wave catenary riser extension. The first 1 section is tensioned to a flatter catenary shape than a catenary shape of the riser between the upper hang off location and the first installation point, so that a portion of the first section extends detached from the riser.

摘要： An offshore assembly to operate a facility, in particular an underwater oil and gas production facility. The offshore assembly has: a semi-submersible support structure arranged in a body of water and having at least one tubular portion; a wind turbine to generate electricity and equipped with a tower, a nacelle and a blade assembly. The offshore assembly also has at least one back-up power source mounted on the semi-submersible support structure to generate electricity. A plurality of compartments are stacked on top of each other within the tubular portion. Each of the compartments is dedicated to housing respective equipment to perform respective functions, and a cooling and ventilation system cools and ventilates the plurality of compartments.

摘要： A process for liquefying and simultaneously purifying natural gas from acidic compounds is provided. The process involves pre-cooling a natural gas flow in a cryogenic exchanger, pre-treating the pre-cooled natural gas flow inside a pre-treatment unit and obtaining a purified flow, heat recovering and obtaining a higher temperature flow, compressing the higher temperature flow and obtaining a first compressed recirculation flow, cooling the first compressed recirculation flow and obtaining a compressed and cooled flow, and separating from the compressed and cooled flow a recirculation flow portion of natural gas. One or more cooling steps are carried out by a flow of nitrogen circulating inside a closed nitrogen refrigeration cycle.

摘要： 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.
