Abstract: A method of automatically inspecting a weld bead deposited in a plurality of passes in a chamfer formed between two parts by performing the following steps: positioning at least one emission electromagnetic acoustic sensor on one side of the chamfer and at least one reception electromagnetic acoustic sensor an opposite side of the chamfer, the ultrasound wave emission sensor being configured to emit Rayleigh surface waves; while depositing a pass, automatically moving the sensors to follow the movement of welding electrodes along the chamfer; activating the sensors while they are moving to enable the emission sensor to generate and emit Rayleigh waves towards the pass of the weld bead that is being deposited, the reception sensor receiving the ultrasound signals transmitted and/or reflected in said pass; and reiterating the operation for the entire pass of the weld bead.

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 modular installation for liquid/gas separation of a multiphase fluid such as crude oil. The installation has a plurality of unitary separation devices, each constituted by an enclosure co-operating at its base with a coaxial connection piece connected to a support structure resting on the sea bottom or suitable for being connected thereto. The support structure being suitable for receiving a plurality of the unitary separation devices in reversible manner so as to be able to perform disconnections at will, in particular for increasing the separation capacity of the installation and/or for performing maintenance on the unitary separation device at the surface.

Abstract: A method of monitoring mechanical behavior of an undersea pipe (2) transporting fluid under pressure and made by assembling a plurality of unit pipe elements (4). A calibration step is performed consisting of using a measurement cable having an optical fiber sensor to measure deformations experienced by each pipe element while it is subjected on land to various mechanical stresses in predetermined directions and magnitudes, and, on the basis of the measurements, establishing the mechanical signature of each pipe element. A monitoring step is performed consisting of using a measurement cable (18) having an optical fiber sensor that makes uses Brillouin backscattering and is helically positioned at constant pitch (p) on each pipe element with the handedness of the helical pitch alternating for two adjacent pipe elements to recover variations in optical signal injected into the sensors while the pipe is in service.
