Abstract: A device for recovering a vessel at sea from a surface station, the recovery device includes a cradle with negative buoyancy, intended to support the vessel, a lifting device comprising an upper frame and a set of hangers connecting the cradle to the upper frame, lengths of the hangers being variable so as to make it possible to raise and lower the cradle, a guide float capable of having a predetermined positive buoyancy, the guide float being interposed between the cradle and the upper frame so that the cradle is intended to support the guide float during the raising of the cradle, the guide float being configured and connected to the cradle in order to guide the vessel moving on the surface of the water with a speed of movement comprising a positive component along an axis x associated with the upper frame, toward a front part of the guide float when the guide float has the predetermined positive buoyancy, the guide float being in connection with three degrees of freedom in rotation with the cradle.

Abstract: A sonar system includes a towfish comprising a first body linked to a second body, the first body being elongate along a longitudinal axis and comprising a plurality of acoustic transmitters distributed along the longitudinal axis, the sonar system comprising a cable linked to the second body and via which a surface carrier ship is intended to tow the towfish, the first body being mounted to pivot, with respect to the second body, about an axis of rotation so that, the first body can switch, by pivoting with respect to the second body about the axis of rotation, from an operational position to a capture position; the axis of rotation being substantially an axis of movement of the towfish, the longitudinal axis being substantially vertical in the operational position of the first body and being substantially horizontal in the capture position of the first body, when the towfish is totally submerged and towed by the carrier ship.

Abstract: A drive device includes a screw-and-nut system comprising a threaded rod and a first nut that is connected to the threaded rod by means of a screw connection; a gearset, allowing a rotational movement to be transmitted to the threaded rod, a first toothed wheel and a second toothed wheel engaged with the first toothed wheel; a set of stops comprising a first stop connected to the first wheel rotating about an axis of rotation of the first wheel and a second stop connected to the second toothed wheel rotating about an axis of rotation of the second wheel, the first stop and the second stop being configured and arranged to butt against one another so as to limit an angular travel of the threaded rod at a first angular position in a first direction.

Abstract: A fairing intended to fair an elongate object intended to be at least partially immersed, the fairing comprises a plurality of fairing portions, each fairing portion comprising a plurality of fairing elements, the fairing elements comprising a canal intended to accept the elongate object and being profiled in such a way as to reduce the hydrodynamic drag of the at least partially immersed elongate object, the fairing elements being intended to be pivot-mounted on the elongate element around the longitudinal axis of the canal, the fairing elements being joined together along the axis of the canal and articulated to one another, the portions of fairing rotating freely about the canal relative to one another.

Abstract: A fairing element to fair an elongate element comprising a canal to accept the elongate object and being profiled in such a way as to reduce the hydrodynamic drag of the elongate object when the elongate object is at least partially immersed, the fairing element comprises a leading edge and a trailing edge, the fairing element being intended to be pivot-mounted on the elongate element around the longitudinal axis of the canal, the fairing element comprising a bearing edge comprising a first bearing edge which is mitered with respect to the leading edge, the first bearing edge being arranged in such a way that the distance between the leading edge and the bearing edge, considered perpendicular to the leading edge, decreases continuously, along an axis parallel to the leading edge, from a first end of the first bearing edge to a second end of the bearing edge, the fairing element being referred to as a mitered fairing element, the mitered fairing element comprising a first part and a second part which are joined together along a first bearing edge so that the fairing element can pass from a deployed configuration in which the trailing edge is parallel to the leading edge to a folded configuration in which the fairing element is folded along the first bearing edge.

Abstract: A towing assembly comprising a towing and handling device intended to tow a faired elongate element, the towing device comprises a winch allowing the faired elongate element to be wound in and paid out through a guide device that allows the elongate element to be guided, the guide device comprising a first groove the bottom of which is formed by the bottom of the groove of a pulley, the first groove being delimited by a first surface having a profile that is concave in a radial plane of the pulley, the width of the first groove and the curvature of the profile of the first curved surface in the radial plane being determined in such a way as to allow the fairing element, under the effect of the rotation of the fairing element about the axis of the elongate element under the effect of the traction of the elongate element with respect to the guide device along the longitudinal axis thereof, to flip from a turned-over position in which the fairing element is oriented with its trailing edge toward the bottom of the first groove into an acceptable position in which it is oriented with the leading edge toward the bottom of the first groove.
