    [0001] The present invention relates to a vessel equipped with a system for transferring people between the ship and a stationary or almost stationary object at sea, such as a fixed and floating wind turbine or another vessel.
    [0002] It applies in particular to a maintenance vessel carrying technicians on fields of offshore wind turbines whose operation requires maintenance operations. Document EP 1 315 651 discloses a maintenance ship equipped with a telescopically expandable bridge that can be removably connected to a pillar at sea constituting a support column of a wind turbine to ensure the transfer of persons between the ship and the ship. 'wind turbine.
    [0003] The telescopic gangway, which can be extended or retracted by means of at least one actuator, such as a hydraulic cylinder, has an end mounted on the deck of the ship about parallel and vertical axes to the deck of the ship under the action respectively at least one actuator and a drive means for lifting the bridge around the parallel axis and a rotational movement of the bridge around the vertical axis perpendicular to the deck of the ship. The telescopic gangway carries at its free opposite end a device for coupling the bridge to a portion of the pillar of the wind turbine. The coupling or connection device is suspended from a connecting platform fixed to the end of the telescopic gangway via a transverse axis, the suspension being such as to allow a certain freedom of movement around this axis and two other axes perpendicular to each other. In addition, the connecting device is equipped with two jaws that can be actuated by actuators, such as hydraulic cylinders, and can cooperate with a guide rod and connecting rod 3031956 2 integral with the wind turbine pound parallel thereto so that the connecting jaws can close around the connecting rod to thereby couple the bridge to the wind turbine pillar and ensure the transfer of personnel between the ship and the wind turbine. However, such a connecting device is of a relatively complex structure and the presence of three orthogonal pivot axes connecting the platform assembly and connecting device to the end of the telescopic bridge makes it difficult to position the two jaws of connection around the connecting rod before the operation of closing these jaws around the connecting rod. The object of the invention is to overcome the above disadvantages of the prior art. For this purpose, the invention proposes a vessel equipped with a system for transferring people between the ship and a stationary or almost stationary object at sea, such as a fixed or floating wind turbine or another vessel, comprising a telescopic gangway. may be extended or retracted by means of at least one actuator and one end of which is mounted on the deck of the pivoting vessel controlled by at least one actuator about an axis parallel to the ship's deck and rotatable controlled by means of driving around an axis perpendicular to the ship's deck and the opposite end may be removably attached to the object at sea via a coupling device assembled at the opposite end of the bridge, and which is characterized in that the coupling device comprises two jaws disposed on either side of the opposite end of the telescopic gangway, provided respectively with airbags and adapted to be arranged between two parallel uprights secured to the object at sea and fixed therebetween by inflating the cushions.
    [0004] Preferably, each of the two airbag jaws is pivotally mounted to the opposite end of the telescopic gangway by an actuator about an axis perpendicular to the floor of the telescopic gangway so as to allow the two jaws to rotate. occupying a position close to each other towards the telescopic gangway allowing the introduction of the two jaws between the two amounts of the object at sea and, once introduced between the two uprights, a position spaced one from the other to which the cushions can be inflated to fix the two jaws between the two uprights. Advantageously, the coupling device further comprises two pads located on either side of the end of the telescopic gangway and bearing respectively on the two uprights of the object at sea when attaching the two jaws between these two amounts. Preferably, the two airbag jaws and the two support pads are mounted on a support structure assembled at the end of the bridge via a resilient ball joint connection. Advantageously, the two airbag jaws are pivotally mounted respectively on two sides of the two support pads adjacent to the telescopic gangway and extending perpendicular to the floor thereof. According to a preferred embodiment, the support structure comprises two rigid bars extending transversely on either side of the end of the telescopic gangway and on which are fixed respectively the two support pads which extend in a direction perpendicular to the floor of the telescopic gangway and the two airbag jaws extend forward of the end faces of the two support pads in opposite directions to the end of the telescopic gangway. Advantageously, the two support pads are integral with two sleeves threaded respectively on the two rigid bars and can be fixed on these bars at a spacing adjustment position of the two airbag jaws as a function of the spacing distance. two amounts of the object at sea.
    [0005] Each actuator for pivoting an airbag jaw relative to the associated bearing pad comprises a cylinder, in particular a hydraulic jack, interposed between the support pad at the rear of the latter and at least one arm integral with the face of the airbag jaw opposite to that with the airbag. Preferably, each airbag jaw is constituted by a flat plate of generally rectangular shape and each support pad is constituted by an arcuate plate of generally rectangular shape, whose concave face intended to bear against a corresponding amount of the object at sea comprises a protective coating of elastomeric material. The support structure of the inflatable cushion jaws and the support pads comprises a personnel transfer dock between the telescopic gangway and the object at sea. The vessel further comprises an actuator control and control device. extending or retracting the telescopic bridge, the actuator pivoting the latter about the axis parallel to the deck of the vessel and the drive means for rotating the bridge around the axis perpendicular to the bridge of the vessel and adapted to deactivate these actuators and the rotational drive means when the bridge is attached to the object at sea by the jaws of the coupling device so that the telescopic bridge acts as a passive gateway. The control and control device is able to control also the pivoting actuators of the two jaws and the airbags and, when an excessive load is exerted on these jaws fixing the telescopic bridge to the amounts of the object at sea, the device is able to cause the deflation of the cushions and to control the actuators 10 to effect the pivoting of the jaws in one direction releasing them from between the two uprights of the object at sea. The end of the telescopic gangway is mounted on a platform for supporting a cockpit comprising the control and control device, which platform is rotatably mounted on the deck of the ship under the action of the drive means which can be constituted by a set electric geared motor and the actuator for pivoting the bridge around the axis parallel to the bridge is constituted by a jack, including hydraulic, interposed between the end of the telescopic gangway and the rotating platform. The telescopic gangway with at least two sections, one expandable relative to the other, is provided with two bridge extension and retraction actuators, each actuator comprising a hydraulic motor integral with the non-expandable section thereof. ci, and whose drive shaft carries a pinion, and a rack meshing with the pinion and secured to the extensible section along one side thereof and under the latter. The invention also relates to a method for coupling a ship, as defined above, to a stationary or almost stationary object at sea, such as a fixed or almost floating wind turbine or another vessel, via a bridge extending telescopically under the action of at least a first actuator, and one end of which is mounted on the deck of the ship so as to be pivotable under the action of at least one second actuator about an axis parallel to the deck of the vessel and to rotate about an axis of rotation 5 perpendicular to the deck of the ship under the action of a drive means, and the opposite end may be removably attached to the object at sea via a coupling device assembled at the opposite end of the bridge, and which is characterized in that it comprises the steps of: - approaching the ship, stabilized by a dynamic positioning system, the object in sea, - of lev age and rotation of the telescopic gangway by the second actuator and the drive means 15 at a specific position relative to the ship, - extending the bridge by the first actuator to a determined distance from the amounts of the object at sea, 20 - automatic activation of the first and second actuators and the drive means of the bridge so as to compensate the swell and allow the coupling device provided with the two airbag jaws to be fixed relative to the amounts 25 of the object at sea, - extension of the bridge over the distance remaining between the amounts of the object at sea and the coupling device until the jaws are introduced between the two uprights and the pads 30 the bridge are supported on these amounts, and - spacing of the jaws to the amounts and inflation of the cushions to fix the bridge between the amounts of the object at sea. Furthermore, it takes the deactivation step of the aforementioned actuators and the drive means of the gateway so that the gateway behaves like a passive gateway, the dynamic positioning system of the ship remaining active. The method further comprises the steps of deflating the jaw cushions, moving the jaws toward the bridge to unhook the jaws from between the two studs of the object at sea and retracting the bridge to disengage the jaws from the jaws. between the two uprights in case of overload applied to these jaws.
    [0006] The invention will be better understood, and other objects, features, details and advantages thereof will become more clearly apparent from the following explanatory description made with reference to the accompanying schematic drawings given by way of example only, illustrating a Embodiment of the invention and in which: - Figure 1 is a perspective view of a vessel connected to a pillar of a wind turbine at sea via a telescopic transfer bridge according to the invention; - Figure 2 is an enlarged perspective view along the arrow II of Figure 1, the ship is not shown; FIG. 3 is a partial top view of the vessel showing the telescopic transfer bridge in an inactive stowed position; - Figure 4 is a perspective view along the arrow IV of Figure 2 without the pillar of the wind turbine; FIG. 5 is a bottom perspective view of the telescopic gangway along arrow V of FIG. 4; FIG. 6 is an exploded perspective view of the coupling device of the invention intended to be assembled at the end of the telescopic gangway; Figure 7 is an enlarged perspective view of the coupling device of the invention; FIG. 8 is a bottom perspective view along arrow VIII of FIG. 7; FIG. 9 is a reduced scale view of the coupling device along the arrow IX of FIG. 7; - Figure 10 is a top view along the arrow X of Figure 2; and Figs. 11A-11H are schematic top views of a windmill pillar, ship, and transfer bridge assembly showing different relative positions of the ship and the bridge relative to the windmill pile. Referring to the figures, reference numeral 1 designates a ship, for example of the "maintenance ship" type, 15 for transporting the personnel to access a stationary object at sea 2, such as for example a pillar forming a support column. a fixed wind turbine at sea, the stationary object 2 may also consist of a support pillar of a fixed platform 20 at sea, such as a drilling platform. However, the object at sea 2 can be almost stationary, that is to say that it can be constituted by a floating wind turbine which oscillates and moves very locally or by another ship.
    [0007] In the application to a fixed wind turbine at sea, the personnel may comprise technicians able to climb the pillar 2 by means of a ladder 3 integral with the pillar 2 along the latter in order to carry out maintenance operations. of the wind turbine.
    [0008] In order to allow the personnel to access the pillar 2 of the wind turbine from the ship 1, the latter is equipped with a telescopically extendable or retractable bridge 4 comprising at least two sections, a first section 5 and a second section 6 be extended or retracted relative to the first section 5 as indicated by the double arrow C in FIG. 2 by means of at least one actuator 7, preferably two in number. By way of example, each actuator 7 comprises a hydraulic motor 8 fixed to the first section 5 of the bridge 4 under this section in the vicinity of its free end and on one side thereof, the hydraulic motor 8 having its motor shaft carrying a pinion 9, and a rack 10 meshing with the pinion 9 of the hydraulic motor 8, which rack is secured to one side of the second gateway section 6 below and all along this side. The two hydraulic motors 8 with gears 9 and the two racks 10 are arranged symmetrically with the longitudinal median plane of the two bridge sections 5, 6 and perpendicular to the floor 11 of the gateway 4. However, the second gateway section 6 can be extended. or retracted by any other type of actuator, such as for example at least one hydraulic jack interposed between the two bridge sections 5, 6.
    [0009] The first gangway section 5 comprises two pairs of rollers 12 secured to each side below and allowing the second gangway section 6 to slide without friction on the first gangway section 5 between its extended and retracted positions.
    [0010] Each of the bridge sections 5, 6 is provided with two lateral guardrails 13, 14. The gangway section 5 has its end opposite to that comprising the actuators 7 mounted on the bridge 1a of the pivotal vessel 1 controlled by at least an actuator 15 about an axis Al-A2 parallel to the deck la of the ship 1. In addition, the end of the gangway section 5 is rotatably mounted by a drive means 16 relative to the deck a of the ship 1 about an axis B1-B2 perpendicular to the bridge of this 35 vessel. The pivot axis A1-A2 of the bridge section 5 relative to the bridge 1a of the ship 1 is integral with a platform 17 rotatably mounted about the axis B1-B2 relative to the bridge 1a of the ship 1. Preferably, two actuators 15 are provided for pivoting the bridge section 5 and may be constituted by two hydraulic cylinders 15 symmetrically disposed at the longitudinal median plane of the bridge 4 being interposed between the upper ends of two rails 13 of the bridge section 5 and the rotating platform 17.
    [0011] The means 16 for rotating the gateway 4 about the axis B1-B2 is preferably constituted by a set of electric motor and gearbox housed in the bridge of the ship 1 and coupled to the rotating platform 17 .
    [0012] The rotating platform 17 supports a cockpit 18 in which an operator can sit. The free end of the second gateway section 6 carries a coupling or connecting device 20 enabling the end of the bridge section 6 to be removably attached to the wind turbine pillar 2. According to the invention, the device of FIG. coupling 20 comprises two jaws 21 disposed on either side of the end of the bridge section 6, provided respectively with airbags 22 integral with the faces of the jaws 21 located opposite the sides of the end of the section 6, which jaws 21 may be disposed between two parallel cylindrical uprights 2a of the pillar of the wind turbine 2 and fixed between these two uprights by inflating the cushions 22 as will be seen later. The two uprights 2a extend parallel to the wind turbine pillar 2 along it and are fixed to this pillar via a plurality of parallel pairs of horizontal arms 2c diverging from the wind turbine pillar 2. Scale 3 for accessing the wind turbine 3031956 11 is fixed between pairs of support arms 2c at a location between the wind turbine pillar 2 and the two vertical uprights 2a which provide protection of the ladder 3.
    [0013] The two jaws 21 are pivotally mounted at the end of the extensible section 6 of the bridge 4 respectively about two axes D1-D2 located on either side of the bridge section 6 perpendicular to the floor 11 thereof. last.
    [0014] The controlled pivoting of each jaw 21 about the pivot axis D1-D2 is provided by an actuator 23, which will be defined later, and which allows the two jaws 21 to occupy a position close to one another towards the bridge section 6 to allow the introduction of the two jaws 21 between the two uprights 2a of the pillar 2 and, once introduced between these two uprights, a position spaced apart from each other to which the cushions 22 can be inflated to fix the two jaws 21 between the two uprights 2a.
    [0015] The coupling device 20 further comprises two fixed pads 24 located on either side of the end of the bridge section 6 and able to bear respectively on the two uprights 2a of the pillar 2 when fixing the two jaws 21 between these two uprights. The two airbag jaws 21 and the two support pads 24 are mounted on a common support structure 25 which is assembled at the end of the bridge section 6 via a resilient ball joint connection. 26. Preferably, each jaw 21 is constituted by a flat plate 27 of generally rectangular shape extending in a plane perpendicular to the floor 11 of the bridge section 6 and whose face turned away from the bridge section 6 comprises the airbag 22 which is fixed and extends over substantially the entire surface of this face.
    [0016] Each support pad 24 is constituted by an arcuate plate 28 of generally rectangular shape, whose concave front face intended to rest on a corresponding upright 2a of the pillar 2 comprises a protective coating 29 of elastomeric material. The convex or dorsal face of the arcuate plate 28 of each support pad 24 comprises stiffening ribs 28a and a sleeve 30 consisting of a tubular portion with a square section integral with the convex face of the support pad 24 transversely to the sides longitudinals of the plate 28 of this pad. The two longitudinal sides of the plate 28 of each support pad 24 extend in a plane perpendicular to the floor 11 of the bridge section 6.
    [0017] The support structure 25 of the jaws 21 and support pads 24 comprises two coaxial rigid bars 31 extending transversely on either side of the end of the bridge section 6 and on which the two skids are respectively fixed. 24 and which extend in a direction perpendicular to the rigid bars 31. More specifically, each rigid bar 31 has a rectangular cross-sectional shape and each support pad 24 is secured to the corresponding rigid bar 31 by its The two airbag jaws 21 are pivotally mounted about the axes D1-D2 respectively at two of the sides of the support pads 24 adjacent to the bridge section 6 and extending perpendicularly. 30 at floor 11 of the latter. Each actuator 23 allowing the pivoting of the corresponding jaw 21 relative to the support pads 24 around the axis D1-D2 is preferably constituted by a jack particularly of the hydraulic type 35 whose rod 23a is connected to a yoke 32 integral with the sleeve 30 of the support pad 24 and the body 23b is integral with two parallel arms 33 themselves integral 3031956 13 of the face of the plate 27 of the jaw 21 opposite to that comprising the airbag 22. The two parallel arms 33 each of the jaws 21 is disposed above and below the corresponding rigid bar 31 in two planes parallel to the rigid bar 31 and is connected at their opposite ends to the jaw 21 by an axis 34 perpendicular to the two arms 33 23b of the jack actuator 23 which extends parallel to the sleeve 30 and to the rigid bar 31. Thus, the actuator 23 allows, via s arms 33 and the axis 34, the pivoting of the jaw 21 about the axis Dl-D2 between its positions close to the gateway section 6 and spaced therefrom.
    [0018] The two jaws 21 extend forwardly from the end faces of the support pads 29 and opposite the end of the gangway section 6. These jaws are inclined towards the longitudinal median plane of the jaws 21. the bridge 4 to their position 20 ensuring their introduction between the two uprights 2a and are substantially parallel to this median plane to their position allowing their attachment between the two uprights 2a. Each assembly consisting of a jaw 21, a support pad 24, an actuator 23, the arms 33 and the axis 34 of pivoting of the jaw 21, is mounted on the corresponding rigid bar 31 at a selectively adjustable position to allow an adjustment of the spacing of the two jaws 21 on either side of the bridge section 6 as a function of the spacing distance between the two uprights 2a of the windmill pillar 2. For this purpose, each sleeve 30 is provided along the latter with a series of holes that can come coaxially with threaded holes of the corresponding rigid support bar 31 to secure the sleeve 30 and, therefore, the pad 24 for supporting the jaw 21 at a chosen position on the rigid bar 31 3031956 14 by fastening screws passing through these bores and tapped holes. The support structure 25 of the jaws 21 and the support pads 24 comprises a dock or personnel transfer platform 40 to which the rigid bars 31 are secured on either side of the latter and which is fixed to the end of the bridge section 6 via the elastic ball joint 26 being disposed substantially in the same plane as that of the floor 10 of the bridge section 6. The dock 40 is provided with two parts lateral members 41 forming a safety railing and an end wall 42 fixed between the two lateral portions 41 transversely thereto and being able to come close to the bars 3a of the ladder 3 in order to allow a person of the service The dock 40 includes a clevis portion 43 disposed between the two rigid bars 31 in the midplane of the dock 40 perpendicular to the latter and extending between the two latched portions. railing member 41 and in which clevis portion 43 is pivotally mounted to a cylindrical pin 44 via a cylindrical axis 45 extending through the clevis portion 43 in a direction perpendicular to the two legs of the clevis portion and which is fixed thereto by a tip 46 secured to one end of the shaft 45 projecting from one of the branches of the clevis portion 43. A resilient sleeve 47, for example of elastomeric material, is housed in the cylindrical pin 44 being traversed by the axis 45. The cylindrical pin 44 has a tab 47 integral with the pin 44 perpendicular to it and which is fixed to another tab 48 of a fixed plate 49, for example by welding, at the end portion of the bridge section 6 under its floor 11. The connection between the tab 47 of the pin 44 3031956 15 and the tab 48 of the connecting plate 49 is provided by a set a cylindrical sleeve 50 and elastic sleeve of elastomeric material 51 passing through the tabs 47, 48 with the sleeve 51 housed in the tab 47, the axis 50 being secured at its end through the tab 48 by a tip 50a. Thus, the support structure 25 at dock 40 is connected to the end of the bridge section 6 by the elastic ball joint connection 26 allowing self-centering of the jaws 21 between the two uprights 2a of the windmill pillar 2 during the operation of fixing the jaws 21 to these amounts. In addition, the elastic ball joint 26 absorbs the relative movements of the bridge 4 vis-a-vis the pillar 2 once the jaws 21 attached to the latter. The ship 1 is equipped with a device 60 for controlling and controlling the actuators 7 extending or retracting the telescopic gangway 4, the pivoting actuators 15 of the telescopic gangway 4 around the axis A1-A2 and means 16 for rotating the telescopic gangway 4 around the axis of rotation B1-B2. This device is preferably housed in the cockpit 18 as symbolized by the reference numeral 60 in FIG. 4. This control and control device 60 is also able to control the actuators 23 for pivoting the two jaws 21, as well as the inflation and the deflation of the cushions 22 of the jaws 21.
    [0019] The control and control device 60 is connected to the hydraulic control circuit of the actuators 15 when they are constituted by hydraulic cylinders which are connected by piping to a pressurized hydraulic reservoir which can be positioned in the engine room of the engine. ship. The device 60 is also connected to the hydraulic control circuit of the actuators 23 when they are constituted by hydraulic jacks, the jacks 23 being connected to a flexible pipe along the telescopic gangway 4 and connected to a hydraulic reservoir under pressure which can also be positioned in the engine room 5 of the ship and be the same as that supplying the actuators 15. The control and control device 60 is also connected to a hydraulic supply circuit of the actuators 7 when they are constituted by hydraulic motors and an electrical supply circuit of the electric motor of the means 16 for rotating the telescopic gangway 4 around the axis Bl-B2. As shown in FIG. 3, the telescopic gangway 4 can occupy an inactive stowed position 15 on the deck 1a of the ship 1 with its two bridge sections 5, 6 retracted into one another. The gangway occupies its stored position by being arranged obliquely relative to the longitudinal direction of the ship 1 and the cockpit 18 is located forward of the ship 1. However, the cockpit 18 may be located behind the ship 1 and the The gangway 4 can occupy its inactive row position by extending in a direction substantially transverse to the longitudinal direction of this vessel.
    [0020] Although this is not shown in FIG. 3, the telescopic gangway 4 is mechanically locked to the deck 1 of the ship 1 by a kind of pin which connects the bridge 4 to the deck 1 of the ship 1 during the navigation of the latter so that the Gateway 30 4 can not move under the action of the swell. Such a pin can be connected to the bridge of the ship 1 by a chain to make it captive. The method for coupling the vessel 1 to the pillar 2 of the wind turbine via the telescopically extensible bridge 4 is already partly in the foregoing description and will now be explained.
    [0021] The vessel 1 travels to the site of the wind turbine field by means of its propulsion system and its dynamic positioning system with the telescopic gangway 4 occupying its inactive row position of FIG. 3. The dynamic positioning system allows the ship 1 to stay in the same position despite winds and sea currents. Before arriving at the site of a wind turbine, in the situation in which the spacing distance between the two uprights 2a of the pillar of each wind turbine 2 is known in advance, the spacing distance between the two jaws 21 may be pre-set by attaching the jaw support sleeves 21 and support pads 24 to the rigid bars 31 at a suitable setting location. Once this spacing adjustment of the jaws 21, the telescopic gangway 4 is unlocked from the bridge of the ship 1 by removing the pin mechanical locking means.
    [0022] Next, the ship approaches the wind turbine and the operator present in the cockpit 18 controls via the control and control device 60 the hydraulic jack actuators 15 to lift the telescopic gangway 4 around the pivot axis Al-A2 and the drive means 16 with an electric motor for rotating the telescopic gangway 4 around the axis of rotation BlB2 in order to allow the passage of the telescopic gangway 4 above the guards -body of the ship 30 to a position where the bridge 4 has its longitudinal axis substantially in alignment with the two uprights 2a of windmill pillar 2. The operator, through the control device and control 60 , activates the actuators 7 to 35 hydraulic motors 8 to deploy the expandable bridge section 6 relative to the bridge section 5 to a position substantially mid-lacquered the extensible bridge section 6 is stopped at a distance close to the uprights 2a of the windmill pillar 2, for example about three meters, and the operator then activates the wave compensation system 5 allowing the end of the bridge section 6 provided with its coupling device 20 and thus the jaws 21 to be fixed relative to a terrestrial reference constituted in this case by the amounts 2a of the windmill pillar 2. This compensation is carried out by automatic activations by means of the control and control system 60 of the hydraulic cylinder actuators 15, the driving means 16 and the actuators 7 with hydraulic motors 8, so that the jaw coupling device 21 remains fixed relative to the wind turbine pillar 2 and, during this time, the vessel 1 maintains its position thanks to its dynamic positioning system. The operator then controls the actuators 60 with hydraulic motors 8 through the device 60 to deploy the expandable bridge section 6 over the remaining distance relative to the post 2a, in this case about three meters with the system for compensation of waves. still in operation by automatic actuations 25 actuators 15 with hydraulic cylinders and the drive means 16 of the bridge 4, until the pads 24 come into abutment via their protective coatings 29 respectively on both 2. It should be noted that the operator can also perform positioning corrections with the actuators 15, 16 at the same time as the latter compensate in order to improve the positioning of the jaws 21 relative to the uprights. 2a of the wind turbine pillar 2. In addition, during the introduction of the jaws 21 between the two uprights 2a before the pads 24 does not come In abutment with these, the jaws occupy their inclined position toward the median longitudinal plane of the bridge 4 and can come into contact with these uprights to self-center between them thanks to the elastic ball joint connection. 26 connecting the coupling device 20 to the end of the bridge section 6. Then, the operator controls via the device 60 and actuators with hydraulic cylinders 23 the spacing of the jaws 21 by pivoting about the axes D1-D2 relative to the pads 24 in support of the uprights 2a at a position in which the jaws 21 are substantially parallel to the longitudinal median plane of the bridge 4 and the inflation of the cushions 22 which exert on each of the uprights 2a a force energetically blocking the two jaws 21 between the two uprights 2a.
    [0023] Once the cushions 22 have been inflated so as to block the jaws 21 between the two uprights 2a, the operator controls, via the device 60, the stopping of the wave compensation, that is to say that controls the actuators with hydraulic cylinders 15, the drive means 16 and the actuators 7 with hydraulic motors 8 to disable them so that the bridge 4 can behave as a passive mooring allowing the gateway 4 to move freely relative to the wind pillar 2 according to its three 25 degrees of freedom. The transfer of personnel from the ship 1 to the wind turbine pillar 2 can then be carried out via the bridge 4 and the vessel 1 has its dynamic positioning system remaining active. Under these conditions, the transfer of personnel by the bridge 4 can be carried out easily and safely as well as the staff can re-board on the vessel 1 by the bridge 4 safely after completing its maintenance work on the wind turbine. During the behavior of the bridge 4 as a passive mooring connecting the ship 1 to the wind turbine pillar 2, the control and control device 60 can be designed to monitor with appropriate sensors the races or clearance of the bridge 4 according to its three degrees of freedom and this device may be required to unhook or disengage the jaws 21 from between the two uprights 2a of the windmill pillar 2 in 5 cases of too much load applied to the device of coupling and due to conditions too agitated sea. In fact, the control and control device 60 is led to monitor three work areas of the bridge 4, a first so-called security zone where the transfer of personnel between the vessel 1 and the wind turbine pillar 2 can be safely carried out, a second so-called warning zone where the personnel is not authorized to use the bridge 4 and a third danger zone due at too rough a sea leading the device 50 to control the deflation of the cushions 22, the actuators with hydraulic cylinders 23 to bring the jaws 21 to their close position and inclined towards the bridge section 6 and the actuators 7 with hydraulic motors 8 for retract the bridge section 6 and, therefore, disengage the deflated cushion jaws 22 from between the two uprights 2a of the wind turbine pillar 2, with automatic raising of the gangway 4 by the actuators 15. Once the operations have been completed After the maintenance work has been completed on the wind turbine, the operator controls, through the device 60, the deflation of the cushions 22, the pivoting by the actuators with hydraulic cylinders 23 of the jaws 21 at their close position and inclined towards the bridge section 6 the retraction of the bridge section 6 in the bridge section 5 to unhook or disengage the jaws 21 from e the two uprights 2a of the wind turbine pillar 2, the rotation by the drive means 16 of the bridge 4 around the axis B1-B2 and the lowering by the hydraulic jack actuators 15 of the bridge 4 around from the Al-A2 axis to its inactive storage position on the bridge 3031956 21 vessel 1 and to which the gateway is locked by the pin mechanical locking means. FIGS. 11A to 11D show different ship orientation configurations 1 relative to the wind turbine pillar 2 according to the directions of the marine current and wind symbolized by a double arrow with the bridge 4 connected at one of its ends to the uprights 2a of the pillar and its opposite end to the vessel on its longitudinal axis or "axial bridge". The circled portion coaxially surrounding the pillar 2 constituting a safety zone, for example about five meters. FIGS. 11E to 11H show the same directional conditions of the marine current and the wind as in FIGS. 11A to 11D, but with the bridge having its end opposite to that connected to the wind turbine pillar 2 connected to one side of the vessel or "Lateral bridge". This lateral gangway configuration is preferred to that of an axial gangway because the ship 1 20 can never hit the windmill pillar 2. The above described transfer system of the invention makes it possible to transfer personnel between the maintenance vessel. 1 and a wind turbine at sea safely in sea conditions of 25 significant height Hs1 / 3 to 3 meters. As already explained above, the transfer of the invention can be applied almost stationary, such as a floating wind turbine which oscillates and moves very locally. Under these conditions, the system could be programmed to additionally follow oscillations of the docking location by optical technical means. The transfer system can also be applied to another vessel and it will then again be necessary to compensate for the oscillations of this docking vessel. system of an object
