Abstract: The present invention is a filtration system and a method for cleaning a filtration system. The filtration system comprising a hydraulic circuit Cp recycling the permeate stream to the feed side of the membrane and/or a hydraulic circuit Cr recycling the retentate stream to the feed side of said membrane. The method injects an amount of a chemical product into the filtration system in the hydraulic circuit Cp or in the hydraulic circuit Cr or upstream of the cross-flow filtration membrane, setting the proportion of recycled permeate stream or recycled retentate stream collected in the hydraulic circuit Cp and/or Cr to enable the recycling of a significant amount of unreacted chemical product having passed through the cross-flow filtration membrane to the feed side of said cross-flow filtration membrane.

Abstract: The invention provides a method of connecting together two unit elements (4, 4′) of a fluid transport pipe, each unit pipe element being made of metal alloy and being covered in an outer insulating coating (6, 6′) made of a thermoplastic material, with the exception of an end portion that does not have an outer insulating coating, the method comprising a step of butt-welding together two unit pipe elements at their end portions having no outer insulating coating, a step of mechanically assembling at least two rigid shells (14, 16) made of a thermoplastic material on the end portions of the unit pipe elements not having an outer insulating coating, and a step of keeping the shells sealed against the outer insulating coating of the two unit pipe elements.

Abstract: A method of monitoring thermomechanical behavior of an undersea pipe (2) transporting fluid under pressure and made by assembling unit pipe elements (4), comprising determining a mechanical signature specific to each unit pipe element, using a measurement cable (16) having an optical fiber sensor using Brillouin backscattering to measure deformation of the pipe element while it is subjected on land to various mechanical stresses in predetermined directions and magnitudes, and establishing a stiffness matrix associated with the mechanical signature of each pipe element, a step of determining a thermal signature specific to each unit pipe element, which step consists in measuring the temperature changes of the unit pipe element while it is being subjected on land to various different electrical heating powers, and in establishing a thermal transfer function associated with the thermal signature of each pipe element, and a monitoring step consisting of recovering.

Abstract: A method of monitoring variation in the thrust exerted by at least one buoy exerting traction on an undersea pipe, wherein: 1) the deformation of at least one optical fiber is measured by measuring variation of an optical signal in said fiber extending on the surface or embedded securely in the bulk of at least one of the following support elements: a) the buoy; b) at least a portion of: b1) the length of the tubular wall of the pipe or b2) an anticorrosion coating or a thermally insulating material fastened on the surface of said pipe, on which said buoy exerts traction, and c) an abutment part secured to said pipe or buoy, and on which said buoy exerts said thrust; 2) a variation of said thrust exerted by said buoy is determined as a function of said variation of the optical signal.

Abstract: A method of installing at sea a double-walled preheated undersea pipe for transporting fluids, wherein for each new pipe section to be assembled to a pipe that is already installed at sea: the method involves preheating the inner wall unit element inside the outer wall unit element of the new pipe section; assembling the inner wall unit elements of the new pipe section to the inner wall of the pipe that is already installed at sea; assembling the outer wall unit element of the new pipe section to the outer wall of the pipe that is already installed at sea; lowering the new pipe section into the sea; and repeating the above for other new pipe sections to be assembled so as to prestress the pipe while it is being installed at sea.
