Abstract: A device for installing and handling a module of a subsea processing station, comprises a frame, and a hydraulic system comprising hydraulic cylinders each comprising a cylinder body, and a piston intended to be put into contact with a foot and movable inside the cylinder body between a first mechanical abutment corresponding to a deployed position of the piston and a second mechanical abutment corresponding to a retracted position of the piston. The piston divides the internal volume of the cylinder body into a first chamber and a second chamber. The first chamber is supplied with hydraulic fluid by two independent hydraulic circuits comprising a shock-absorbing circuit able to move the piston between the deployed and intermediate positions located between the deployed position and the retracted position defined by a hydraulic abutment, and a controlled-lowering circuit able to move the piston between the intermediate position and its retracted position.

Abstract: A method of connecting together two unit elements (4, 4′) of a fluid transport pipe, each unit pipe element 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 includes: a step of welding together two abutting unit pipe elements; a step of positioning an annular sleeve (14) around a cut-back and in part around the outer insulating coatings of the two unit pipe elements, the sleeve being made of a thermoplastic material; a step of fastening the sleeve in sealed manner by weld bonding on the outer insulating coatings; and a step of applying an external pressure on the sleeve to enable it to be deformed elastically and match the shape of the respective end portions of the two unit pipe elements.

Abstract: A process for lining a steel pipe for the subsea transport of fluids comprises machining of an annular cavity in an inner wall of the pipe to be lined. The cavity is set back longitudinally relative to an end of the pipe. The deposition by welding of a first resurfacing layer includes a corrosion-resistant metal alloy on the inside of the cavity. Surface machining of the first resurfacing layer is done to the internal diameter of the pipe. A liner made of corrosion-resistant steel alloy is introduced into the pipe. Deposition by welding includes at least one second resurfacing layer made of corrosion-resistant metal alloy on the inner wall of the pipe between the end of the liner in contact with the first machined resurfacing layer and the corresponding end of the pipe. Surface machining of the second resurfacing layer is done to the internal diameter of the pipe.

Abstract: A combined metrology method is provided for calculating the distance, the roll and pitch attitudes, and the relative orientations between two undersea points of interest. The method comprises positioning on the sea bottom a long-range acoustic positioning system having acoustic beacons, calibrating the system in order to determine the positions of the beacons relative to one another, deploying a vehicle on the sea bottom, taking a plurality of scenes around each point of interest in order to acquire point clouds, and processing the point clouds in order to calculate the coordinates of points in a common reference frame defined by the array of beacons and centered on the position of one of the acoustic beacons.

Abstract: The invention provides a method of emptying an undersea fluid transport pipe (2) that is submerged and full of water, the method comprising pumping out at least a portion of the water present inside the submerged pipe by means of a submersible pump unit (6) connected to a point of the pipe, the volume of water pumped out from the inside of the pipe being compensated by a gas injected under pressure into the submerged pipe from a point (18) thereof that is situated higher than the connection point (12; 14) to the submersible pump unit. The invention also provides an installation for performing such a method.

Abstract: A method for testing an underwater filtration system as well as the underwater testing device which enables the operation of filtration systems in aquatic conditions. The testing method includes introducing a flow of water into the underwater testing device via a water inlet, said underwater testing device including at least one filter, bringing said flow in the underwater testing device up to said filter, obtaining a filtrate downstream of said filter and discharging said filtrate into the environment via a discharge pipe. The underwater testing device is placed underwater at a depth of at least 500 meters.

Abstract: A method of installing and implementing a rigid tube (10) referred to as a “main” tube, wherein the following steps are performed: a) lowering an end of the main tube from a floating support or vessel (13) on the surface (14) to below sea level (14) to be connected to undersea equipment (16) that is immersed (17); and b) maintaining the main tube as immersed in this way for a given period of time. The said main tube (10) is caused to pass through a cylindrical orifice (4) of circular section in a stress limiter device, the orifice having a slippery internal coating (3) secured to a support structure (9) secured to the floating support or vessel, the service tube thus being suitable for sliding in contact against the slippery coating during steps a) and b).
