Abstract: A method for controlling a thruster of a marine vehicle includes a body and a thruster mounted on the body of the vehicle, the vehicle being at least partially immersed in a liquid and moving with respect to the liquid along an axis of displacement in a direction of displacement and rotating about at least one axis of rotation perpendicular to the axis of displacement with a rotational speed, the thruster including an upstream propeller and a downstream propeller along the axis of displacement in the direction of displacement. The method including a stabilization step, in which the thruster is controlled such that the main axis of the upstream flow generated by the upstream propeller at a given instant t is an estimated main axis on which a position of a center of the downstream propeller, situated substantially on the axis of rotation of the downstream propeller, is estimated to be situated at a later instant t+dt at which the flow generated by the upstream propeller at the given instant t reaches the downstream propeller, the estimated main axis depending on the rotational speed of the vehicle.

Abstract: A method controlling a thruster of a marine vehicle at least partially submerged in a liquid includes a body and a thruster including two propellers, each propeller including blades intended to turn about a rotation axis of said propeller, the method including a step of low-speed maneuver controlling, during which the thruster is controlled in such a way that each propeller generates a flow directed toward the flow generated by the other propeller and reaching the flow generated by the other propeller.

Abstract: A device for handling and towing a submersible object installed on a ship, comprises: a tilting structure supported by a support, and able to pivot with respect to the support about a first axis parallel to a plane to extend horizontally, the tilting structure equipped with a first guide device allowing the cable to be guided, a pivot connection about a second axis situated in a plane substantially perpendicular to the first axis of rotation, arranged to allow a rotary part of the tilting structure to rotate with respect to the support, the rotary part equipped with the first guide device, a stabilizing device arranged to keep the rotary part of the tilting structure in a deployed position with respect to the support as long as a torque of the relative pivoting between the rotary part and the support about the second axis is below or equal to a predetermined threshold, and to allow the rotary part, equipped with the first guide device, to rotate with respect to the support about the second axis once a torque of relative pivoting between the rotary part and the support about the second exceeds the threshold.
