Definitions
- the present invention relates to a fairlead for guiding an anchoring element.
- it finds application in permanent anchor devices with an integrated chain stopper, in areas such as marine, offshore and marine renewable energies.
- immersed anchor devices of the submerged fairlead type with integrated chain stopper, requires taking into account the forces experienced by the anchor line at the level of the apparatus, the behavior of the anchor line at the interface with the device and the ease of installation of the anchor line.
- Permanent long-term anchorages are common to offshore sectors, with Floating Production Storage and Offloading (FPSO) and Floating Storage Regazification Units (FSRUs) as potential stay several decades on their production site.
- FPSO Floating Production Storage and Offloading
- FSRU Floating Storage Regazification Units
- Offshore structures such as floating production supports, construction or drilling platforms, loading and unloading buoys, and recently the floating platforms of EMRs (offshore wind turbines, thermal energies of the seas, etc.) are anchored on a desired site by means of anchor lines consisting of chains and / or cables connecting them to anchor points with the seabed.
- anchor lines consisting of chains and / or cables connecting them to anchor points with the seabed.
- chains connected to the anchor points are used, going up to the floating unit via fairleads serving as chain entry guides.
- chain traction systems winches, windlasses, etc.
- chain restraining systems chain stoppers located on the deck of the floating unit.
- anchoring devices are placed outside the deck, for example in hull planks, whether in an emergent or submerged manner.
- the anchor lines are pre-installed and connected to the anchor points.
- messenger lines are passed, from the deck of the floating unit, in the fairleads, termination connectors connecting these messenger lines to the anchor lines.
- the anchor lines are then energized to the pre-tension required for anchoring, and the chain stops are activated to maintain the anchor lines in their configuration.
- anchor chains are continuously working under the stresses induced by wind, swell, tides and currents.
- the movements produced on the anchor chains accelerate fatigue breakage of the chains if curved guide guns or small radius sprockets are used. This is why anchor gear is usually designed with curved guides or large radius sprockets.
- Anchoring equipment of this type is known, such as that described in US 4,742,993. This is a curved guide fairlead for anchor cables that can rotate freely around a vertical axis connected to the floating unit.
- the device is designed for cables, and therefore does not include a chain stopper immersed.
- the system uses a tubular body connected to a separate hinged assembly, and does not allow passing of the messenger line cable, chain, Kenter meshes and special connectors, as is usually required as part of the installation. anchor lines.
- the foundations attaching the system to the floating support have a vertical axis pivotal connection with a first moving body.
- This body serves as guidance to the anchor chain via the use of a sprocket or curved guide directly integrated.
- An arm having at its end (anchor point side) the chain stopper is connected to the pivoting body via a horizontal axis pivotable connection allowing the final to accommodate changes in azimuth angles and elevation of the line. anchor.
- the stopper is fixed which induces that any twist or torsion is taken over the next mesh of that maintained in the stopper. In the case of an extreme twist, this can be particularly detrimental to the fatigue strength of the anchor chain.
- the loads and stresses that weigh on the anchoring lines at the level of the floating support are of different natures: corrosion and wear phenomena, impacts, fatigue in flexion (mainly out-of-plane bending), high tensions, phenomenon of spin / twist lines.
- the known systems generally respond to the problem of fatigue in flexion out of the plane, but none solves the problem of spin / torsion of the anchor line.
- the chain behaves non-linearly, which disrupts its normal operation.
- the mesh undergoing this spin has its fatigue life drop very sharply.
- One of the aims of the invention is therefore to solve the aforementioned problems, by proposing an anchor type anchor-type embedded chain stopper integrated which solves the problem of spin / torsion of the anchor line at the interface with the anchor.
- the subject of the invention is a guide fairlead of an anchoring element having a longitudinal axis and allowing the anchoring of a unit, such as a floating unit, to an anchor point, said fairlead comprising guide means adapted to guide the anchoring element in translation between the unit and the anchor point, and locking means adapted to block the translation of the anchoring element in the guide means.
- the locking means are mounted on the guide means at least partially free in rotation about an axis parallel to the longitudinal axis of the anchoring element when it is guided in the guide means.

- the locking means comprise at least one valve-type locking element pivotally mounted on the support between a first locking position in which the blocking element is able to block the anchoring element in translation in the guiding means and a second non-locking position in which the locking element leaves the free anchoring element in translation in the guide means,
- the locking element or elements are provided with mechanical actuating means, hydraulic or electrical, allowing the passage of these blocking elements from the locking position to the non-locking position and vice versa,
- the actuating means comprise at least one jack-type element whose one end is connected to the support and the other end is connected to the locking element, so that the deployment of the actuating means causes the locking elements of the blocking position to pivot towards the position without blocking,
- the actuating means comprise at least one cable fixed on the blocking element, for example by means of a ring-type element, so that a pull on the cable causes the pivoting of the element of blocking the blocking position to the position without blocking,
- the guide means comprise a first guide assembly intended to guide the anchoring element in a first direction and comprising an attachment interface for fixing the fairlead on the unit, and a second guide assembly pivotally mounted by relative to the first guide assembly about an axis and intended to guide the anchoring element in a second direction forming a non-zero angle relative to the first direction, and the locking means are mounted on the second guide assembly ,

- the second guide assembly 2, 4 is intended to guide the anchoring element C in a second direction which forms a non-zero angle with the first guide direction.
- This second guide assembly 2, 4, and in particular the arm 2 allows the system to accommodate variations in elevation angles of the anchoring element C which is an anchor chain C in this example.
- This anchor chain C passes into the arm 2 via the guide cone 4 and then via locking means not shown in FIGS. 1 and 4a, before going up to the first guide assembly 1.
- Transition means 3 are provided for guiding the anchoring element C at the transition between the first and second guide directions, therefore between the first guide assembly 1 and the second guide assembly 2, 4.
- these transition means comprise a gypsy type element 3, provided with a groove in addition to its footprints.
- This gypsy 3 is mounted free to rotate about an axis 8a formed in a portion 8 of the guide 8, 9 pivoting from the first guide assembly 1.

- the locking means 5 comprise second rotation limiting means 13a to 13d which cooperate with first rotation limiting means 15a to 15d disposed in the guide means 1 to 4.
- the first rotation limiting means 15a to 15d comprise circular grooves 15a to 15d centered on the axis of rotation of the ring 19 with respect to the bearing ring 10, thus centered on the rotation axis of the locking means 5.
- the second rotation limiting means 13a to 13d comprise elements 13a to 13d, such as pins 13a to 13d, which are each guided in rotation in the circular grooves 15a to 15d.
- the rotation as the assembly of the locking means 5 relative to the arm 2 can be obtained with a single circular groove 15a to 15d cooperating with a single stud-type element 13a to 13d.
- the locking means 5 comprise two blocking elements 1 1a, 1 1b, of the type of valves 1 1a, 1 1b pivotally mounted on the support 12.
- these blocking elements 11a, 11b pivot on the support 12 between a locking position in which the anchoring element C is locked in translation. in the guide means 1 to 4, and a non-locking position in which the anchoring element C is free in translation in these guide means 1 to 4.
- valves 1 1 a and 1 1 b stop the anchor element C which passes through an opening 20 in the support 12, thus blocking its translation.
- these valves 1 1 a and 1 1 b pivot away from the support 12 which has the effect of releasing the anchoring element C.
- the shape of the opening 20 in the support 12, and the valves 1 1 a, 1 1 b, depends on the nature of the anchor element C.
- the anchoring element C is a chain C consisting of several links, and the opening 20 has a shape adapted to the passage of each link of the chain C.
- the Valves 1 1 a, 1 1 b are adapted to lock the chain C between two of its links in the locking position.
- a single valve type locking element is used (not referenced) for the blocking means 5.
- the single valve comes to stop the anchoring element C against the edge of an opening formed in the support 12, thus blocking its translation.
- the single valve pivots away from the support 12, thus releasing the anchoring element C.
- the blocking means 5 or stopper 5 are allowed to pivot about the longitudinal axis of the anchor line, at the end of the second guide assembly 2, 4, in a predefined angular range.
- the allowed angular range is defined by the dimension of the studs 13a to 13d and the length of the grooves 15a to 15d.
- Remote actuating means are provided on the blocking means 5, in order to enable activation or deactivation of the locking in translation of the anchoring element C in the guide means 1 to 4.
- FIG. 2a A first example of actuating means 14a, 14b is shown in Figures 2a and 2b.
- each actuator 14a, 14b may be actuators of the hydraulic or electric cylinder type 14a, 14b.
- An actuator 14a, 14b of this type will then be used by locking element 11a, 11b.
- one of the ends of each actuator 14a, 14b is connected to the support 12, rotating about an axis parallel to the main plane of the support member 12, and opposite the pivot axis of the element of blocking 1 1 a, 1 1 b associated with the free end of this locking element 1 1 a, 1 1 b.
- the other end of each actuator 14a, 14b is connected to the associated locking element 11a, 11b, in rotation about an axis parallel to the axis of pivoting of the locking element 11a. , 1 1b relative to the support piece 12.
- each actuator 14a, 14b to the locking element 11a, 11b associated, is sufficiently raised relative to the connection point of this actuator 14a, 14b with the support 12, and sufficiently far from the pivoting axis of this locking element 1 1a, 1 1b relative to the support 12, so that the deployment of each actuator 14a, 14b effectively causes the pivoting of the locking element 1 1a, 1 1b associated from the blocking position to the unlocking position.
- the actuating means may also be mechanical actuating means 16a, 16b, 17a, 17b, 18a, 18b allowing the passage of the locking element or elements 1 1a, 1 1b from the locking position to the position without blocking, and vice versa.
- the principle of such mechanical means includes providing the entire system of cables and accessories return to allow remote actuation of the locking elements 1 1 a, 1 1 b.
- the guide means 1 to 4 are provided with rings 18a, 18b for guiding cables 16a, 16b along the guide means 1 to 4.
- rings 18a, 18b can be arranged for example on the arm 2 of the second guide assembly 2, 4.
- Each cable 16a, 16b is fixed on a locking element 11a, 11b, for example by means of rings 17a, 17b.
- traction on one of the cables 16a, 16b causes the pivoting of the blocking element 1 1a, 1 1b associated with the locking position to the position without blocking.
- the fairlead according to the invention thus makes it possible to substantially reduce the forces due to torsion on the part of the anchoring element C which is held at the level of the blocking means 5.
- This fairlead allows a rotation of the anchoring element C around its longitudinal axis over a defined range of angles. This relative freedom in rotation reduces all the problems on the units for which the anchor line may have twisted.
- This fairlead thus improves the behavior of the anchor line C, reduces the stresses on the holding portion of the anchor line C, such as the holding mesh of an anchor chain C, and facilitates the installation of the anchor line C when connecting this anchor line C to a unit such as a floating unit.
- the invention is not limited to the exclusive use of two locking elements 1 1 a, 1 1 b in the locking means, a single element, as shown in Figure 4b, or more than two, may also be suitable.
- the invention is not limited to means for limiting the rotation of the locking means 5 relative to the guide means 1 to 4, which consist in the cooperation between circular grooves 15a to 15d with studs 13a to 13d. .
- Other solutions are possible to obtain this limitation.
- the invention is not limited to the exclusive use of a gypsy type transition means 3.
- a curved guide type transition means (not shown) which is formed in, or housed in the pivotable guide 8, 9 may also be suitable.
