    Abstract: An electronic control system configured to control a variable-configuration lay ramp of a pipeline laying vessel, to lay a pipeline on the bed of a body of water, is configured to: acquire data including data related to the configuration of the lay ramp, data related to the laying vessel, and data related to the forces transmitted by the lay ramp and the laying vessel to the pipeline; generate a plurality of step sequences to change the configuration of the lay ramp from a first to a second work configuration; and select a best step sequence as a function of the plurality of step sequences and the acquired data, so as to minimize the stress induced in the pipeline at each intermediate configuration between the first and second work configuration.

    Abstract: A stinger extends away from an end of a vessel, and a pipeline passes over the stinger as the pipeline is laid from the vessel. The inclination of the pipeline increases as the pipeline passes along the stinger and after leaving the stinger until the pipeline reaches an inflection point beyond the end of the stinger at which inclination is at a maximum. Inclination of the pipeline thereafter reduces until the pipeline touches down on the seabed. A method of S-laying the pipeline includes providing guides on the stinger that limit lateral movement of the pipeline relative to the stinger and moving the vessel and the stinger during S-laying to an orientation in which the longitudinal axis of the stinger is inclined to the path of the pipeline just laid. The vessel and the stinger are rotated about a vertical axis passing through or adjacent to the inflection point.

    Abstract: A method of removing ammonia from a continuous vent gas stream of a urea plant, in particular of a medium-pressure section of a urea plant, includes a step of removing ammonia from the continuous vent gas stream of the urea plant using a controlled-combustion process including at least a first lean, oxygen-poor combustion step performed in the presence of an understoichiometric amount of oxygen acting as the sole comburent, and in a reducing atmosphere of hydrogen.

    Abstract: A guide system configured to guide a pipeline from a laying vessel onto the bed of a body of water has a float unit; a trolley, which is housed inside the frame, is selectively connectable to a pipeline spanning a given or designated path between the laying vessel and the bed of the body of water, and is configured to roll along the pipeline, parallel to the given or designated path; and at least one motor connected to the trolley) to selectively adjust the distance between the float unit and the laying vessel.
