Receiving assembly for receiving a seagoing vessel and system for recovering and deploying such a vessel in the sea

A receiving assembly for receiving a seagoing vessel, wherein said seagoing vessel is able to be suspended from an articulated arm of a handling structure which is provided with a lifting cable that is intended to carry the seagoing vessel and to move said vessel in a vertical direction so as to at least one of deploy and recover said vessel in or from the sea from a floating building on which said handling structure is secured, said receiving assembly comprising a lower part which comprises receiving means of said vessel, said receiving means having a passage through which the lifting cable is capable of passing, said receiving means defining a cavity which is capable of receiving said vessel when said vessel is suspended from the lifting cable and being arranged so as to ensure the blocking of rotational and translational movements in the vertical direction upward of the seagoing vessel, in relation to the receiving means, when the seagoing vessel is received by the cavity and comes to bear against said receiving means, said assembly being arranged so as to be able to be suspended from the articulated arm of the handling structure leaving at least one degree of rotational freedom about an axis perpendicular to the vertical direction between the lower part of the receiving assembly which comprises the receiving means and the handling structure, and the receiving assembly further comprising at least one mechanical fuse which is provided to shear off and disconnect a bottom part from the articulated arm when the range of the relative oscillating movement of the bottom part in relation to said arm with at least one degree of rotational freedom is superior to a predetermined threshold.
