Abstract: A joining device of a continuous conduit is for changes in slope of seabeds. The continuous conduit defines a longitudinal direction substantially coinciding with the longitudinal direction of structural development of the continuous conduit. The continuous conduit has a longitudinal structural continuity and a fluidic continuity. The joining device includes a joint that includes at least one first joining branch, at least one second joining branch and at least one third joining branch. The first joining branch extends along the longitudinal direction and provides longitudinal structural and fluidic continuity of the continuous conduit and connects with a piece of the continuous conduit. The second joining branch provides longitudinal structural continuity of the continuous conduit. The third joining branch provides fluidic continuity of the continuous conduit. The second joining branch is exclusively suitable for providing the longitudinal structural continuity of the continuous conduit, and is unsuitable for providing the fluidic continuity.

Abstract: A method of laying a pipeline in the bed of a body of water advancing a digging assembly along a pipeline laid along a path on the bed of the body of water, and digging a trench along the path in the bed of the body of water by means of the digging assembly, so a portion of pipeline settles onto the bottom of the trench. The method also includes acquiring, by means of the digging assembly, data related to the bathymetric profile of the portion of pipeline laid on the bottom of the trench, and comparing the acquired data with a set of permissible values. Further, the method includes emitting an error signal when the acquired data does not fall within the set of permissible values.

Abstract: A blower device includes a Coanda effect fluid flow amplifier having a suction opening, an outlet opening to provide an amplified fluid flow, an inner passage along an amplifier central axis passing through the suction opening and the outlet opening. An inlet conduit inputs pressurized fluid into the inner passage for drawing the ambient fluid from the suction opening to the outlet opening by Coanda effect, achieving amplified flow. A diffuser downstream of the amplifier includes diffuser side walls that delimit a diffuser inner side surface extending about a diffuser central axis arranged along the amplifier central axis and terminates with a first flow inlet open end facing the outlet opening, and an opposite second flow outlet open end delivers further amplified fluid flow. At least one side opening is upstream of the second flow outlet open end to allow additional ambient fluid to be sucked into the diffuser.

Abstract: A lifting apparatus comprises: a base part, a lifting rope, a sheave assembly, a first rotatably mounted sheave, around which the rope passes and from which the rope extends downwardly to a load, a second rotatably mounted sheave and a drive for moving the sheave assembly. The sheave assembly is mounted for pivotal movement relative to the base part about an axis of pivoting spaced from the axis of rotation of the first sheave and coincident with the axis of rotation of the second sheave. During movement of the load relative to the base part, the first sheave is moved by the drive to compensate for that relative movement, the movement of the first sheave being such that the vertical component of the movement of the first sheave relative to the load is less than the vertical component of the movement of the base part relative to the load.

Abstract: A method of joining a first pipe section to a second pipe section includes positioning the two pipe sections in an end-to-end configuration to define therebetween a joint to be welded, measuring the degree of alignment of the pipe sections when they are in the end-to-end configuration in a position ready for welding, ascertaining the relative movement required of the pipe sections in order to improve their alignment, effecting the relative movement so ascertained, and welding together the two pipe sections. The method may include the use of geometric data of the end of the pipes in order to ascertain the relative movement required of the pipe sections. A control unit may be used to calculate, using such data, a target orientation that lines up the pipe sections. The measuring step may be performed using, for example, a laser or a camera and backlight.

Abstract: 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.

Abstract: A heat-delivery apparatus (12) heats a heat-shrinkable sleeve (10) on a pipe (2). The heat-delivery apparatus (12) includes one or more heater elements (20) which define an interior heating surface that surrounds the sleeve (10). An air space is thus defined between the exterior of the sleeve (10) and the interior heating surface. The flow of air, that would otherwise be generated by the step of applying heat, within said air space is controlled or restricted for example by means of fins (50, 50s, 60) that control or restrict the airflow, fully or partially sealing the air space with one or more sealing members (70), or fans (80) that generate an opposing airflow (82).
