A method of laying a pipeline from a laying vessel into a body of water includes guiding the pipeline along a supporting structure of a laying ramp. The method also includes acquiring a first data item correlated to a position of the pipeline at a free end of the laying ramp using an optical sensor or an acoustic sensor. The method further includes determining whether the acquired first data item is within an acceptance range predetermined as a function of a configuration of the supporting structure and a size of the pipeline. Additionally, the method includes emitting an control signal when the acquired first data item is not within the acceptance range. Determining whether the acquired first data item is within the acceptance range includes processing the acquired first data item to compare it the first data item to an information stored in a memory.

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.

A vessel for laying a pipeline includes a plurality of workstations disposed along a pipelaying path that includes an upstream portion away from a first end of the vessel and a plurality of ramps in the region of the first end of the vessel. The plurality of ramps includes a first ramp which is disposed along the pipelaying path, whose inclination is adjustable and which has a first upstream end and a second downstream end, and a second ramp which is disposed along the pipelaying path downstream of the first ramp, whose inclination is adjustable and which has a first upstream end and a second downstream end. The downstream end of the first ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel and the upstream end of the second ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel. An external ramp assembly is provided, including ramps and that can be pivoted relative to one another and locked in a selected position by a locking arrangement.
