Abstract: A double liquid distribution device (1) suitable for use in in a fractionating or wash column (10) including a high collector tray (2) connected to a manifold support (7) via at least two longitudinal liquid downflow ducts (5, 6), the manifold support (7) supporting at least two series of transverse tubular manifolds (8, 8a 8b) and serving to feed liquid respectively to the first series of manifolds (8a) via a first longitudinal duct (5) and to the second series of manifolds (8b) via a second longitudinal duct (6), each manifold (8, 8a 8b) including distribution orifices (8c) in its under face that are suitable for distributing the liquid onto the top face of the packing bed (9). The two longitudinal liquid downflow ducts (5, 6) are connected together in a low portion (5b, 6b) by a communication device (11) fitted with a valve (12) having controlled opening that is suitable for allowing the liquid to be transferred between the two longitudinal ducts in a controlled manner.

Abstract: A coupling system (12) between a riser (2) and an underwater supporting structure (10), includes a coupling seat (13) and a coupling head (14) which can be inserted in the seat. A pull connector (16) constrains the head (14) to the seat (13) to prevent the extraction of the head (14) but to allow rotation of the head (14). A clamping connector (18) constrains the head (14) to the seat (13) to prevent transversal translation and rotation to the head (14) and the seat (13). The pull connector (16) can be actuated alone and independently from the clamping connector (18) to make a provisional, pull-only connection between the head (14) and the coupling seat (13). The clamping connector (18) can be actuated independently from the pull connector (16) to allow postponing the complete clamping with respect to the provisional connection.

Abstract: A system and method remotely measure in real time through sound waves, geometric parameters of a pipeline in the launch step. An acoustic transceiver positioned in a pipeline includes an acoustic transmitter emitting an input acoustic signal into the pipeline, based on an electric pilot signal. An acoustic receiver detects the input acoustic signal and generates a first electric measurement signal, dependent on the input acoustic signal. The acoustic receiver receives an input return signal dependent on the input acoustic signal and on pipeline geometric parameters, and generates a second electric measurement signal based on the return acoustic signal. A control unit generates an electric pilot signal and connects to the acoustic transceiver and receives the first electric measurement signal and the second electric measurement signal. The control unit measures the geometric parameters of the pipeline based on the first and second electric measurement signals.

Abstract: A trenching assembly lays a continuous pipeline in a trench dug in a bed with uneven bathymetry, the trenching assembly including a trench digging device having a main body; at least four ground contact units, each unit having a height adjustment device, to position each ground contact unit with respect to the main body independently. A trench cutting tool digs in the bed includes a cutting depth adjustment device, for positioning the cutting tool with respect to the main body. A detection device detects bed bathymetry. A control device simultaneously allows cooperation between the detection device, the height adjustment device of each ground contact unit, and the cutting depth adjustment device. A command device cooperates with the control device to adjustment each ground contact unit and the cutting depth adjustment device, to obtain a trench having a height difference lower than a predefined tolerance and a predetermined burial depth.
