    Abstract: A device for jointing elements of a pipeline for the transport of fluids includes a support structure on which a pipeline section to be jointed is intended to be mounted, two parallel fixed rails, four plates each comprising a first element capable of cooperating with a rail and a second element fixed on the support structure. The first and the second elements of each plate is linked by a first cylinder aligned along a first adjustment axis and a second cylinder aligned along a second adjustment axis, and a system for controlling the cylinders of the plates to achieve movements along the first and second adjustment axes and capable of cooperating with a system for guiding in translation the support structure along the longitudinal axis of the pipeline section to allow jointing of the pipeline section and the pipeline element.

    Abstract: A method and system for tensioning a hyperstatic system involves two structures connected to each other, including: a) connecting, by at least one non-adjustable tendon and at least one adjustable tendon which is formed by a tendon coupled to a cylinder in an initially retracted position, an upper structure to a lower structure which is positioned below the upper structure while maintaining zero tension in the tendons; step b) applying a force to the upper structure and/or the lower structure in order to tension each adjustable tendon and to deploy the respective cylinder thereof, the tension of each non-adjustable tendon remaining at zero; and step c) progressively increasing the force until the tension of each non-adjustable tendon reaches a threshold value which brings about a load transfer from the lower structure to the upper structure to allow the lower structure to be supported by the upper structure.

    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 for determining the phase interface level of a multiphase system, includes a tank intended to receive a multiphase system including at least two fluids having distinct phases, and a tube vertically immersed inside the tank. The tube is intended to be filled with a fluid at equal pressure with the fluid contained in the tank at the level of a headspace of the tank. The tube has a plurality of differential pressure sensors per membrane which are spaced apart vertically from each other along the tube to measure the pressure difference between the fluids contained and stratified in height in the tank and the fluid contained in the tube.
