Abstract: An enhanced process is described for the synthesis of urea from ammonia and carbon dioxide, at a high pressure and temperature, with the formation of ammonium carbamate as intermediate, which includes a high pressure synthesis section, comprising at least one separation step by decomposition-stripping with ammonia of the non-converted ammonium carbamate, carried out in a vertical apparatus, commonly called stripper, characterized in that said step also comprises a feeding, in the lower part of said stripper, of a stream of CO2, heated to a temperature ranging from 130 to 230° C., in a quantity of 1 to 15% by weight with respect to the total weight of the fresh CO2 fed to the process, containing a passivating agent in such a quantity that its equivalent content of O2 in moles varies from 0.05% to 0.80% with respect to the moles of CO2 of said stream.

Abstract: 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.
