Abstract: A pipe-joining method for building a hydrocarbon pipeline, in particular an underwater pipeline, includes welding two adjacent pipes to form a cutback, and forming a protective coating about the cutback. Forming the protective coating includes applying an LE (liquid epoxy) resin or a powdered FBE (fusion bonded epoxy) resin to the cutback to form a primer coat; and applying a powdered polypropylene adhesive on top of the still-wet primer coat to form an auxiliary adhesive coat. Forming the protective coating also includes fitting a polypropylene heat-shrink sleeve around the auxiliary adhesive coat; and heating the sleeve to shrink and bond the sleeve to the auxiliary adhesive coat.

Abstract: A leakage detection system configured to detect hydrocarbon leakage from an underwater pipeline in a body of water having a sensor configured to acquire signals related to the temperature of a liquid inside a chamber that is not watertight and which, in use, is full of water and extends along a portion of underwater pipeline susceptible to leakage, and a control unit, which is connected to the sensor and is configured to control if the temperature of the liquid in the chamber is within an expected range and emit a leakage signal when the temperature of the liquid in the chamber is outside the expected range.

Abstract: A joining device configured to join two facing and aligned pipeline sections presents two coupling members selectively couplable to respective pipeline sections at two respective facing flanges located at the ends of respective pipeline sections; a pulling mechanism suitable to move the coupling members towards each other in abutment against the flanges and to temporarily tighten the flanges by moving the coupling members towards each other; and a tightening mechanism suitable to definitively tighten the coupling members while the pulling mechanism keeps the flanges tight.

Abstract: 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, includes a first ramp and a downstream second ramp disposed along the pipelaying path, in the region of the first end of the vessel. Each of the plurality of ramps has a first upstream end, a second downstream end, and an adjustable inclination. 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 includes ramps that can be pivoted relative to one another and locked in a selected position.
