Abstract

A device for rapidly remotely coupling together two vessels, in particular a first ship or floating support and a second ship, comprises: at least one floating and docking structure fastened to or suitable for being releasably fastened to the side and/or the keel of the hull of a second vessel; and at least two actuators spaced in succession from one another in the longitudinal direction of the first vessel. The actuator cylinder of each the actuator is arranged to be fastened to the side of the hull of the first vessel, using a first fastener and pivot hinge device. The end of the rod of each actuator is arranged to be fastened to or suitable for being fastened to the floating and docking structure via a second fastener and pivot hinge device.

First claim

The invention claimed is:

1. A device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship, the device for remotely coupling together the first and second vessels comprising:
at least one floating and docking structure comprising at least one docking float suitable for being ballasted and de-ballasted in order to enable the at least one floating and docking structure to be immersed, and at least one docking element fastened to or suitable for being releasably fastened to a hull of the second vessel; and
at least two actuators spaced in succession from one another in a longitudinal direction of the first vessel, one end of an actuator cylinder of each of the at least two actuators being fastened to the first vessel using respective first fastener and pivot hinge devices,
wherein an end of a rod of each of the at least two actuators is configured for being fastened to the at least one floating and docking structure via respective second fastener and pivot hinge devices.

2. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 1 , wherein the at least two actuators, in a retracted position and fastened to the at least one floating and docking structure via said second fastener and pivot hinge devices, are suitable for being positioned together, vertically or in a position close to a vertical axis, against a hull of the first vessel and out of water when the at least one floating and docking structure is not fastened to the second vessel and when the at least one docking float is de-ballasted.

3. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 1 , wherein the respective first and second fastener and pivot hinge devices at the end each of the at least two actuators each make possible at least a first pivoting movement of each of the at least two actuators about a horizontal first axis perpendicular to a longitudinal axis of a corresponding actuator of the at least two actuators, and
wherein the respective first and second fastener and pivot hinge devices at the ends of each of the at least two actuators also each make possible a second pivoting movement of each of the at least two actuators about a second axis perpendicular to the longitudinal axis of the corresponding actuator of the at least two actuators and situated in a vertical plane containing the longitudinal axis of each of the at least two actuators, and
wherein the respective first and second fastener and pivot hinge devices at the ends of each of the at least two actuators also make possible a third pivoting movement about the longitudinal axis of the corresponding actuator of the at least two actuators.

4. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 1 , wherein when the rod of each of the at least two actuators is fastened to the at least one floating and docking structure, each of the at least two actuators is arranged above a surface of water horizontally or with the rod sloping relative to a horizontal plane at an angle of less than 15 degrees while remaining out of the water, the actuator cylinder of each of the at least two actuators being fastened to a side of a hull of said first vessel at a same height.

5. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 1 , wherein when the at least two actuators are fastened to the at least one floating and docking structure, the at least two actuators are arranged parallel to one another and/or sloping at an angle of less than 30 degrees relative to a first vertical plane perpendicular to a second vertical plane that is tangential to a side of the first vessel.

6. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 1 , wherein the at least two actuators are double-acting hydraulic actuators having the rods, the rods being set to an initial coupling extension position defining a first distance between the first and second vessels and having a hydraulic circuit that is adjusted and/or automatically controlled in such a manner that any departure from the first distance to a second distance is corrected in order to reestablish the first distance between the first and second vessels, and to reestablish the initial coupling extension position of the rods.

7. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 1 , wherein the at least one floating and docking structure comprises at least one attachment element suitable for attaching to the second vessel while the at least one docking float is ballasted at least in part and the at least one attachment element is underwater, and
wherein the at least one attachment element presenting an arrangement and/or shape making the at least one attachment element suitable for being positioned under a bottom of a hull of the second vessel by ballasting the at least one docking float and then for pressing against and/or facing the bottom of the hull of the second vessel by partially de-ballasting the at least one docking float.

8. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 7 , wherein the at least one attachment element is suitable for being underwater is situated on the at least one floating and docking structure at a height such that when the at least one docking float is de-ballasted and said actuators are safely positioned against the first vessel, the at least one attachment element is out of water.

9. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 7 , wherein the at least one attachment element of the at least one floating and docking structure suitable for attaching to the second vessel includes magnetic or pneumatic suction cups suitable for pressing against a side and/or the bottom of the hull of the second vessel.

10. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 7 , wherein the at least one attachment element is constituted or supported by a portion of the at least one floating and docking structure that forms a fork suitable for extending under the bottom of the hull of the second vessel from a first side to a second side and supporting magnetic or pneumatic suction cups suitable for bearing against bilges of the hull of the second vessel.

11. The device for remotely coupling together a first vessel consisting of a first ship or floating support and a second vessel consisting of a second ship according to claim 1 , wherein the at least one floating and docking structure comprises a single floating and docking structure constituted by beams and/or tubes assembled together in a truss assembly forming a tower having the at least one docking float underwater and suitable for being ballasted.

12. The device for remotely coupling together a first vessel consisting of a first ship or floati
