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.
