    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: An object that can be towed in a fluid by a cable along a substantially horizontal transport axis comprises a body suspended under gravity from the cable by a fixing arm, and an exterior hydrodynamic surface that is symmetric with respect to a vertical plane containing the transport axis, so as to limit the lateral lift of the body, and an opening passing through the body along a vertical axis and configured to equalize the pressures of fluid flowing along the exterior surface, making it possible to limit the hydrodynamic forces that may be generated perpendicular to the transport axis giving rise to a force in rotation about the transport axis opposing the effect of gravity.

    Abstract: A towing device intended to equip the deck of a ship (10) and comprising a winch (16), a cable (14) and a fairlead (20), the cable (14) circulating in the fairlead (20) under the action of the winch (16), the fairlead (20) comprising a frame (21) and at least one first and one second sectors, the sectors making it possible to guide the cable (14) in a channel formed in each of the sectors. The device comprises an articulation with a degree of freedom allowing the rotation of the second sector relative to the frame (21) about an axis contained in a plane comprising a first direction in which the cable can extend in the first sector, characterized in that the first sector is secured to the frame (21) and is interposed between the winch (16) and the second sector.

    Abstract: A method for assisting the guidance of a surface vessel intended to tow an underwater device, the method includes a) discretizing the geographical sector around the surface vessel into a plurality of zones, with each zone being classified according to a degree of accessibility from among a set of degrees of accessibility; b) computing a set of candidate trajectories of the surface vessel in the geographical sector, with each candidate trajectory corresponding to a different gyration rate from the current position of the surface vessel; c) classifying each candidate trajectory as a function of the degree of accessibility of the zone of the geographical sector traversed by the possible trajectory, and as a function of the feasibility of one or more predefined actions on the candidate trajectory; d) generating a display of the zones and of the candidate trajectories on a human-machine interface, as a function of their classification and/or a transmission of instructions relating to the actions.
