    摘要: A system for power and data transmission in a body of water to unmanned underwater vehicles comprises a floating surface station for generating electric energy and receiving and transmitting data; an underwater station connectable to at least one unmanned underwater vehicle; at least one submerged depth buoy; and an umbilical, which comprises a power transmission line and a data transmission line, is mechanically and electrically connected to the surface station and to the underwater station, and is mechanically coupled to the depth buoy so that the umbilical comprises a first umbilical section that is stretched between the underwater station and the depth buoy and a second umbilical section that extends loose between the depth buoy and the surface station.

    摘要: A laying tower for laying pipelines on the bed of a body of water has a supporting structure extending along a longitudinal axis and provided with guides parallel to the longitudinal axis; a first clamp, which is mounted on the supporting structure and configured for selectively clamping and releasing the pipeline in a given point along the longitudinal axis; and a second clamp, which is selectively movable along a path, which extends along a first section above the first clamp; and a second section below the first clamp and, partly, below the supporting structure and configured for selectively clamping and releasing the pipeline along the path.

    摘要: A desulfurization gas process includes water vapor, CO2 and SOx (x=2 and/or 3). In a treatment unit, the gas contacts a cooled alkaline aqueous solution having a temperature lower than an initial gas temperature, water and a carbonate of an alkali metal, to cool the gas, condense some water vapor and absorb SOx in the carbonate-containing solution, produce an SOx-depleted gas and an acidic aqueous solution including sulfate and/or sulfite ions. The SOx-depleted gas and a portion of the acidic aqueous solution can then be withdrawn from the treatment unit. Carbonate of the alkali metal can be added to remaining acidic aqueous solution to obtain a made-up alkaline aqueous solution. This solution can be cooled and reused as the cooled alkaline aqueous solution. An SOx absorbent solution includes a bleed stream from a CO2-capture process, sodium or potassium carbonate, and an acidic aqueous solution obtained from desulfurization.

    摘要: A first metal pipe is welded to a second metal pipe in a method of laying pipeline, for example from a pipe-laying vessel at sea. The metal pipes may have an outer diameter greater than 150 mm and a pipe wall thickness of greater than 15 mm. The first pipe and the second pipe are brought together prior to welding so as to sandwich a third type of metal material between the pipe ends. The thickness of the third type of material, immediately before welding may be between 0.05 mm and 2 mm. The third metal material is melted together with the metal material of the first pipe and the second pipe.
