Definitions
- the present invention relates to a movement method for tubular elements according to the characteristics of the pre-characterizing part of claim 1.
- the present invention also relates to a movement system for tubular elements on a vessel according to the characteristics of the pre-characterizing part of claim 4.
- the present invention also relates to vessels according to the characteristics of claims 36 to 38.
- vessels In the present description and in the appended claims by the general expression "vessels" one will indicate ships, boats, rigs, floating structures in general and in particular drillships, semisubmersible drilling rigs.
- tubular elements one will indicate both real pipes suitable to be laid on the sea or ocean bed by means of pipe-laying vessels, or the so-called “risers” which are tubular elements suitable to be reciprocally fastened after one another to form the drilling duct between the vessel and the sea bed and in the underwater drilling wells.
- the vertical duct that connects the vessel to the sea bed, in correspondence with which the drilling of the well occurs.
- Said vertical duct is made up of elements called “risers” which are tubular elements that form a vertical or catenary duct of connection between a control valve placed on the sea bed usually called BOP [Blow Out Preventer] and the vessel.
- the risers are normally flanged tubular elements made up of a main hole and a number of auxiliary lines for the passage of the control fluids, in addition to pushing floating elements inserted around the structure of the riser itself.
- the auxiliary lines can comprise a line for the inlet of sludge (kill line), a line for the recovery of sludge (choke line), two lines relating to the control of the control valve, a pumping line (booster line).
- the present invention in general relates to the movement of tubular elements from a storage zone present on the vessel and handling means of the tubular elements.
- the present invention in particular, relates to the movement of risers from a storage zone present on the vessel towards the derrick.
- the present invention is not limited to the single specific application of the risers but, in general, it is applicable to the movement of generic tubular elements such as in the case of pipe-laying ships.
- the length of the risers or of the tubular elements can be in the range of 22-27 metres and the diameter of the main hole can be in the range of 530-540 mm but it will be evident in view of the present description that the invention is applicable to tubular elements in general, independently of the sizes indicated.
- the risers there are also further elements called "pushing modules" having the function of reducing the weight in water of the single riser.
- the weight of the risers can be in the range of 20-40 tons.
- the risers are connected to one another according to various coupling modes that are considered known for the purpose of the present invention.
- each “riser” is a delicate element that must be moved appropriately. It is necessary to be particularly careful in the phase of taking out from the storage zone, typically a parking zone on the deck of the vessel or a hold. Furthermore, the movement phase on the deck of the vessel for the purpose of taking the riser towards the derrick in order to connect it to the vertical duct of already positioned risers is very delicate as well.
- the risers once connected to one another to form the vertical duct, form the connection between the probe plane of the vessel and the control valve placed on the sea bed usually indicated by the term "Blow Out Preventer". During the drilling activities, the drilling rods are lowered into the riser. To carry out the drilling activity some drilling fluids are used, which are pressure-pumped into the drilling rods that are hollow.
- the drilling fluids are made up of drilling sludge, specially prepared with the addition of various additives to modify its physical properties.
- the drilling sludge pumped through the rods, comes out of the drilling head to go back up towards the surface where it is treated to be recycled and pumped into the well again.
- the sludge goes back towards the drilling means passing through the air space between the main hole of the riser and the drilling rods lowered into it. This is, in fact, the main function of the risers, that is to say, creating an "airtight" passage for the rise of the drilling sludge from the sea bed to the drilling means.
- the tubular elements or risers are usually stored in a covered hold or on the deck of the vessel.
- sea or ocean depths in the range of 3000-4000 metres.
- sea or ocean depths in the range of 3000-4000 metres.
- a depth of about 3700 metres with risers having a length of 27.5 metres it will be necessary to move about 135 risers both in the laying phase of the risers themselves and in the recovery phase from the well towards the storage zone.
- some of the prior art solutions provide the storage of tubular elements according to a storage configuration in which the tubular elements are vertically stored within a hold, in the sense that the longitudinal development axis of the tubular element is placed vertically within the hold.
- Such solutions besides necessarily requiring the resort to lifting cranes with the previously described problems concerning the risks and dangers of management of suspended loads, also require the bottom of the hold to be modified for mounting base supports of the risers, which base supports will have to be replaced for example in the case in which one wants to operate with different risers.
- the hold is essentially free from bridge cranes but a bridge crane is used mounted on the upper part and externally to the hold, that is to say, on the deck of the vessel.
- the hold must be necessarily provided with considerably wide ports that may ensure the access of the external bridge crane to the various zones of the hold for the taking out and the movement of the risers.
- This solution in addition to the need for huge hold ports is also subjected to the previously described problems concerning the risks and dangers of management of suspended loads.
- US-A-4.202.653 describes a method having the features of the pre-characterising portion of claim 1, and a pipe handling system including bridge crane and swing crane for storing and moving pipes to and from a common axial transport between a drilling rig platform and storage racks.
- Components of the systems include a piggyback riser and casing skate, spin rolls for uncoupling the pipe located between the racks and the axial transport, and a modular stabber which can accommodate different sizes of pipes.
- US-A-4.081.084 describes a pipe handling system having the features of the pre-characterising portion of claim 4.
- the movement process is managed manually by the operators who control the bridge crane or the transfer cranes, without the use of automated procedures.
- the presence of the operators in the control zones exposes the operators themselves to conditions of possible danger.
- the risers are not all identical but can differ from each other depending on the depth at which they are suitable to operate.
- a drawback of the prior art systems is that the loading and the taking out of the risers generally occurs manually by the operators who establish the order of loading.
- An error by those who are in charge of the loading may cause following delays in the laying phase for example in the case in which a riser suitable to operate at great depths (that must be taken before the others) has been loaded on a bottom rack and below with respect to a series of risers suitable to operate at shallow depths (that must be the last to be taken).
- the operators in charge of the laying do not notice the error, they might lay at great depths a riser that is not suitable to operate at such depths with the risk of breaks that may cause irreparable environmental damage and compromise the operators' safety.
- the aim of the present invention is to provide an improved movement device and method for the movement of tubular elements from the hold of the vessel to the deck of the vessel itself.
- a further aim of the present invention is to provide an improved lifting device and method for the movement of tubular elements on the deck of the vessel for the purpose of taking the tubular elements to the transfer device that transfers them to the derrick.
- the solution according to the present invention allows to best use the space available inside the hold where the tubular elements are stored obtaining definitely more favourable coefficients of filling of the hold with respect to the prior art solutions.
- the solution according to the present invention allows to eliminate the traditional lifting members, normally made up of bridge cranes, hold elevators and deck cranes, replacing them with more effective and safer devices able to ensure the movement of the tubular elements or risers in conditions of maximum safety. Furthermore, it allows for a high degree of automation of the process of movement of the tubular elements. Moreover, the number of transfers of the tubular elements or risers between different types of machines is minimized.
- the solution according to the present invention allows to solve the safety problems related to the presence of suspended loads because the solution according to the present invention allows to obtain a movement of the tubular elements in a locking condition on the driving means, eliminating all the conditions of presence of suspended loads. This is further advantageous because impacts are prevented, which may damage the tubular elements. Further advantageously the solution according to the present invention also allows to completely automate the transfer phase as well as the hold loading phase, so that the operators no longer have to handle the driving means manually, reducing the possibilities of error and reducing the exposure of the operators to conditions of danger.
- the solution according to the present invention also allows to maintain high standards of operative efficiency also in the case of changes of the crew or of the operators. Furthermore, the solution according to the present invention facilitates the phases of inspection of the tubular elements prior to their taking out from the storage stacks and also allows to know with precision and automatically the position of the various types of tubular elements or risers present in the storage stacks. Moreover, the solution according to the present invention allows for the assembly of the movement devices for tubular elements also on existing ships and, anyway, after the launch of the ship itself, preventing the movement devices from remaining exposed to the weather for long periods of time.
- the solution according to the present invention allows to carry out the movement of the tubular elements or risers on the deck without having to use the on-board cranes and, therefore, completely eliminating the suspended loads, to the advantage of the personnel's safety and of the preservation of the riser from possible damage.
- This is further advantageous as impacts are prevented, which may damage the tubular elements.
- it advantageously allows for an efficient transfer of the tubular elements or risers between the taking out position within the hold or on the deck and the unload position towards the transfer device with one single operation in a constant condition of locking of the tubular element or riser.
- the solution according to the present invention allows to obtain a movement system for tubular elements that is able to manage in an automatic way the entire movement of the tubular elements themselves both in the loading phase of the tubular elements within the storage zone and during the laying phase of the tubular elements.
- the system according to the present invention also allows to have one single subject supplying the entire management and movement chain of the tubular elements, to the advantage of the reciprocal integration of the various constituents of the system and to the advantage of an efficient and safe movement of the tubular elements themselves.
- the solution according to the present invention can be installed on the vessel also once the construction of the latter has been almost completed, thus preventing the equipment and the devices of the movement system from having to be installed in the phase of construction of the vessel, exposing them to the weather and to tough environmental conditions that may compromise their efficiency and functionality. Furthermore, it allows for a high degree of integration with the phase of design of the vessel, which already in the design phase can be pre-arranged to house the system according to the present invention allowing, with an equal capacity of tubular elements carried, to optimize and therefore to reduce the size of the area destined to their storage and therefore of the vessel itself, or, with equal sizes of the vessel, to increase the area intended for their storage.
- the system according to the present invention allows for an easy and fast inspection of the tubular elements also when these are stored within the storage zone, which advantageously allows to carry out their inspection during the navigation phase. Therefore, it is possible to save time during the operations of installation of the tubular elements themselves, or rather preliminarily and beforehand highlighting any possible problems in such a way as to allow to prearrange appropriate actions of correction of the procedure of taking out of the tubular elements from the storage zone keeping into account any possible anomalies evidenced in the preliminary inspection phase.
- the present invention finds application in the movement of tubular elements (6) from a storage zone (14) of a vessel (1) towards at least one laying or use zone (2) of the tubular elements.
- the tubular elements will be risers that are taken from a storage zone (14) that can be a hold or a deposition zone on the deck.
- the risers (6) are ( Fig. 2, Fig.
- the riser ( Fig. 3 ) normally tubular elements flanged in correspondence with a first end (11) and in correspondence with a second end (12) that are opposite ends with respect to the longitudinal development of the tubular element in the form of a riser.
- the riser ( Fig. 3 ) includes a main hole (10) and a number of auxiliary lines (13) for the passage of the control fluids, as well as floating pushing elements inserted around the structure of the riser itself.
- each tubular element or riser is taken from an essentially horizontal condition to an essentially vertical condition to connect it to the series of risers previously installed to form the vertical duct (7) up to the sea or ocean bed (9) where the well closed by the respective control valve (8) is dug.
- tubular elements (6) or the risers can be stored within an internal storage zone (14) such as a hold of the vessel (1) or they can be stored in correspondence with an external storage zone (14), such as a deck of the vessel (1).
- an internal storage zone (14) such as a hold of the vessel (1)
- an external storage zone (14) such as a deck of the vessel (1).
- the system according to the present invention is applicable also to the racks within which the tubular elements are stored on the deck and is advantageous because the bridge cranes or movement cranes, which imply the previously described risks and dangers related to the conditions of movement of suspended loads, are eliminated.
- the present invention advantageously exploits the combination and reciprocal coordination of the movement of the tubular elements (6) that is operated by means of at least two different devices that coordinate with each other to obtain a guided movement of the tubular elements from a storage zone (14), preferably a hold of the vessel (1), to a laying or use zone (2) of the tubular elements, which, for example in the case of a vessel for oil drilling can be ( Fig. 1 ) a derrick (2).
- a first inventive device is ( Fig. 4 , Fig. 5 , Fig. 6 , Fig. 8 , Fig. 9 , Fig. 10 , Fig. 11 , Fig. 12 ) a movement device (5) which is able to manage the movement of the tubular elements in the storage zone (14):
- the movement device (5) interfaces and coordinates ( Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24 ) with a lifting device (4), which is able to manage the movement of the tubular elements between the storage zone (14) and the deck (16) of the vessel (1):
- the lifting device (4) can interface with cranes or driving means, such as a tilter device, able to move the tubular element (6) or the riser between the deck (16) and the laying or use zone (2) of the tubular elements.
- the transfer device (3) can for example be a transfer device of the type usually known by the name of "catwalk", which is considered known for the purpose of the present invention.
- the main components of the developed innovative system can interact and coordinate with one another to automatically manage the whole movement of the tubular elements.
- the movement device (5) that manages the movement of the tubular elements in the storage zone (14) is made up ( Fig. 4 , Fig. 8, Fig. 9 ) of a pair of trolleys (17, 18) that are able to translate ( Fig. 4 , Fig. 5 , Fig. 10, Fig. 11 , Fig. 12 , Fig. 14 ) along a first direction (49) in the air space (51) between the stack (52) or column (15) of risers or tubular elements (6) and a wall or supporting structure (25, 62) whose function will be explained in more detail in the following of the present description.
- the first trolley (17) and the second trolley (18) of the movement device (5) are placed in correspondence with opposite ends of the storage zone (14), that is to say, they are placed on opposite sides with respect to at least one stack (52) of tubular elements and in particular they are placed on opposite sides of at least one stack (52) that are the opposite sides in correspondence with which are the first end (11) and the second end (12) of the tubular elements (6), that is to say, the ends (11, 12) of the tubular elements on which there are the main holes (10) and any holes of the auxiliary lines (13) of the risers or tubular elements (6).
- the first trolley (17) and the second trolley (18) of the movement device (5) are each provided with a base (44) which is sliding ( Fig. 5 , Fig.
- first trolley (17) and the second trolley (18) of the movement device (5) are each provided with a frame (26) with substantially vertical development which is integral with the base (44) and translatable jointly and integrally with the base.
- the frame (26) with substantially vertical development develops for a corresponding height but lower with respect to the height of the hold or of the storage zone (14).
- a cursor (27) is vertically sliding.
- the cursor (27) is provided with at least one engagement means (29, 30) with a corresponding end of the ends (11, 12) of the tubular elements (6). Since the movement device (5) is made up ( Fig. 4 , Fig. 8, Fig. 9 ) of a pair of trolleys (17, 18) each of which is provided with a base (44) sliding according to a first direction (49) and since on each base (44) a corresponding frame (26) is mounted, which is able to constitute a supporting and guiding element for the movement according to a substantially vertical second direction (50) of a corresponding cursor (27) provided with engagement means (29, 30) with a corresponding end of the ends (11, 12) of the tubular elements (6), one obtains that by coordinating the movement of the two trolleys (17, 18) it is possible to:
- the described system can work also according to the opposite sequence to carry out the loading of the tubular elements or risers (6) from the lifting device (4) to the stacks (52) within the storage space.
- the stacks (52) will be provided with retaining elements able to receive one or more rows of tubular elements or risers (6) arranged in columns, in a way absolutely similar to the retaining elements (53) represented with reference to the solution of storage on the deck ( Fig. 34 ).
- the engagement means (29, 30) of the cursor (27) are made in the form of pins that enter the main hole (10) of the tubular element.
- the engagement means (29, 30) are also possible, which can be considered equivalent and, as such, falling within the scope of the present invention.
- the solution with the pins is conceived in such a way that each cursor (27) is provided with at least one respective retractable pin (29, 30) suitable to make an insertion or disengagement movement with respect to the main hole (10) of the tubular element.
- the described movement device (5) is in practice made up of a pair of reciprocally coordinated translating columns, which are placed at the two ends of the storage zone (14).
- the described movement device (5) allows for the movement of the tubular elements within the storage zone both transversely, that is to say, according to the first direction (49), and vertically, that is to say, according to the second direction (50). Furthermore, the described movement device (5) allows to reach any position of the storage zone (14).
- the two translating columns of the movement device (5) are not physically constrained to each other, as usually occurs in a bridge crane, but their alignment and coordination is ensured by the automation system of the machine.
- the device is much more compact with respect to a bridge crane usually used, allowing for its installation on the vessel (1) also once the construction of the vessel has been completed, so that the movement device (5) is not exposed to the weather or to impacts during the phase of construction of the vessel.
- the movement device (5) further presents advantageous solutions to allow for an efficient filling of the storage zone (14), both if it is placed within a hold ( Fig. 1 , Fig. 4 , Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24 ) of the vessel (1) and if it is placed ( Fig. 34, Fig. 35 ) on the deck (16) of the vessel.
- the system is in any case advantageous because it allows, in this case too, to prevent the resort to bridge cranes or cranes with the consequent problems concerning the movement of suspended loads that expose the operators to conditions of danger and that expose the tubular elements (6) to possible impacts and damage. Also in the case of application of the system of the invention with the storage zone (14) placed ( Fig. 34, Fig. 35 ) on the deck (16) of the vessel (1), it is possible to obtain a completely guided movement of the tubular elements (6) that prevents the presence of conditions of suspended loads and allows for a high degree of automation of the process.
- a first particularly advantageous solution consists of the fact that the cursor (27), which is by itself vertically mobile on the frame (26) according to the second direction (50), is further provided ( Fig. 15, Fig. 16 ) with an elevation element (28), which is by itself vertically mobile along the body of the cursor (27) according to the second direction (50).
- the fact of having the elevation element (28) vertically mobile on the body of the cursor advantageously allows to optimize the filling of the hold as it is necessary to observe that the engagement means (29, 30) must be placed at such a height as to allow them to store and take ( Fig. 12 ) the tubular elements in correspondence with the bottom of the hold or the floor of the deck.
- the engagement means (29, 30) must be placed at such a height as to allow for the transfer ( Fig. 21, Fig. 22, Fig. 23 ) of the tubular elements (6) onto the lifting device (4). These two requirements for the engagement means (29, 30) are in contrast with each other because:
- the cursor (27) is provided with two different engagement means (29, 30) that are arranged spaced from each other along the first direction (49) and essentially symmetrical with respect to an axis of symmetry of the cursor (27). In this way it is possible to use:
- the engagement means or pins (29, 30) can be shaped ( Fig. 44 ) with an essentially quadrangular shaped section with radiused edges according to connection radiuses essentially corresponding to the internal radius of the riser.
- the engagement means or pins (29, 30) are provided with at least one portion which is covered by a soft or friction material, such as a gummy material or plastic material.
- the quadrangular shape is particularly advantageous as it allows to have two contact areas spaced from each other between the head (67) and the inside of the tubular element, ensuring greater stability with respect to a solution with a circular head, which in any case will be an adoptable solution, although less preferred with respect to the solution with the quadrangular head.
- each pin (29, 30) is retractable ( Fig. 10, Fig. 11 ):
- the first pins (29) and the second pins (30) of the just described elevation elements (28) as well as the third pins (66) of the tilter device (65) that will be described in the following of the present description, can have the previously described quadrangular configuration ( Fig. 43 , Fig. 44 , Fig. 48, Fig. 49 ).
- the pin (29, 30, 66) can slide ( Fig. 48, Fig. 49 ) within a holder (92), but the head (67), which is the part suitable to get in contact with the tubular element (6), always remains external with respect to the holder (92) also in the withdrawn position of the pin (29, 30, 66).
- This solution allows to be able to adopt interchangeable heads (67) without having to modify the rest of the mechanism of the pins, for example for the purpose of replacement in case of wear or for the purpose of allowing the handling of tubular elements having shapes very different from each other with a same device of general applicability, which will be adapted to the different needs by simply replacing the head (67) only and keeping unchanged the rest of the pin (29, 30, 66) and of the movement device of the pins themselves to obtain the movement between the extracted and withdrawn positions.
- the whole unit of the pin (29, 30, 66), that is to say, comprehensive of the pin itself, of the relative holder (92) and of the relative pin actuator (88), has been designed in such a way as to be able to be installed in a removable manner, for the purpose of facilitating and fastening any possible replacements.
- the pin (29, 30, 66) slides on guide shoes inside the holder (92) and a suitable greasing system is provided to reduce friction and keep the system efficient.
- the pin (29, 30, 66) is movable between the extracted position and the withdrawn position by means of a pin actuator (88) which acts in extension and in traction between the pin itself and the holder (92).
- the pin actuator (88) can be an electrical actuator or a hydraulic cylinder which is advantageously placed below the unit and external with respect to the pin and holder improving accessibility for maintenance or replacement although remaining in a protected position and not interfering with the tubular element during the operations of movement and taking out.
- the positioning of the pin (29, 30, 66) opposite the tubular element (6) can be made in different ways according to the degree of automation that one wishes to obtain.
- a particularly simple and economical solution ( Fig. 48, Fig. 49 ) provides the definition of a Cartesian Plane of movement coordinates on which Cartesian Plane the positions of the tubular elements within the retaining elements (53) are previously defined.
- signals of the movement encoders of the various motors it is possible to carry out a sufficiently precise positioning of the pin (29, 30, 66) in correspondence with the tubular element (6) to be taken out from a stack (52).
- a different solution provides the resort to optical pointing systems that allow to detect the position of the head flange of the tubular element or its end edge in such a way as to control in a more accurate way the positioning of the pin with respect to the insertion hole.
- the sensors (89, 90, 91) not only confirm the positioning, but ensure to prevent impacts between the pin (29, 30) and the tubular element (6) sequentially enabling the movements.
- the automation system and in particular the control unit (63) controls both trolleys (17, 18) and the respective elevation elements (28) and cursors (27) in correspondence with the opposite ends of the tubular element (6), the control unit (63) proceeding with the sequence of the movements only when both systems give a positive result, that is to say, when both the sensors (89, 90, 91) of the pin (29, 30) of the first trolley (17) and the sensors (89, 90, 91) of the pin (29, 30) of the second trolley (18) confirm that the tubular element (6) has been taken out correctly.
- cursor driving means (31) which are preferably mounted on the base (44) of the trolley and are preferably made up of a first motor (35) which by means of a first gear-reducing device (48) actuates a winch (32), preferably a pair of winches (32) which, by means of one or more cables (33) that slide on first snub pulleys (34), allow for the lifting and the lowering of the cursor (27) which is advantageously constrained and guided in the vertical movement by means of the frame (26).
- the movement of the cursor (27) according to the second direction (50) is controlled by means ( Fig. 43 ) of the first motor (35) which by means of the first gear-reducing device (48) actuates the pair of winches (32) which are controlled in a reciprocally synchronized way by means of one single drive shaft.
- Each of the two cables (33) winds on a respective winch of the pair of winches (32) and each cable (33) preferably makes a double trip back and forth between the winch and the first snub pulleys (34).
- each of the two cables (33) is able to support the whole cursor (27) independently of the other of the two cables (33), in such a way that also in the case in which one of the two cables failed, the other would be able to support on its own the whole weight of the cursor (27) and of any loads.
- a double section winch is obtained with two symmetrical cables and with 100 % redundancy.
- This brake mainly has safety purposes because in case of breakdowns it intervenes to stop the lifting system.
- the brake is of the type normally tightened in braking and, for the normal operation of the system, it must be kept constantly deactivated by means of a specific control. In this way in case of breakdowns or failures, at the drop of the control that keeps the brake released, it will intervene and immediately stop the system.
- the brake can also be useful to brake the descent movement of the cursor when it supports the weight of a tubular element (6) during transport.
- the described braking system will intervene on the respective faulty trolley and will also control the activation of the braking system of the other trolley that is not subject to failure, preventing any tubular element that is being carried from possibly bending due to the stopping of one of the two trolleys while the other continues its stroke or movement.
- a compensator device system (86) was realized ( Fig. 50, Fig. 51 ), which allows to balance for any traction difference between the two cables.
- the compensator device (86) by oscillating, compensates for any different traction of the two cables.
- the compensator device (86) can compensate for a different length of the cables, due for example to the progressive extension of the latter due to wear.
- the compensator device (86) will be preferably oscillating between a central position and two positions of maximum inclination that will be preferably corresponding to an inclination of +/- 15 degrees with respect to the central position, even more preferably of +/- 10 degrees with respect to the central position.
- the positions of maximum inclination can be defined by means of rabbet elements that prevent inclinations exceeding the limit value set mechanically.
- One can also provide sensors that generate a corresponding signal of reaching of the maximum inclination limit, in which case the system is no longer able to compensate for further differences between the cables and it is necessary to schedule a maintenance intervention.
- the cursor (27) will be provided with a compensator device (86) intended for the passage of the two cables (33), the compensator device (86) being suitable to incline alternatively on the one side or on the opposite side under the action of the traction difference present between the two cables (33), said inclination of the compensator device (86) compensating for the traction difference present between the two cables (33) in such a way as to bring them in a condition of equal traction and preventing one cable only from being subject to all the stress.

- the fine adjustment and the following corrections will be carried out with the tie-rods of the compensator device (86).
- the compensator device (86) is placed in the low part of the elevator to allow this to be able to exploit all the height of the guiding plate without interfering with the wheels or the snub pulleys. As a result the connections are realized on the sides of the trolley.
- the position of the compensator device (86) is controlled by three limit stops, the central one says that the compensator device (86) is horizontal, while the other two give the signal that the compensator device (86) is too inclined on the one side or on the opposite side.
- the movement of the trolley (17, 18) according to the first direction (49) is guided ( Fig. 6 , Fig. 7 ) by means of a second guide (21) placed below with respect to the development in height of the frame (26) and by means of a third guide (23) placed above with respect to the development in height of the frame (26).

- the third guide (23) is made in the form of a rail on whose opposite sides opposite pairs of third wheels (24) engage, which are placed on a plane essentially orthogonal to the plane on which the frame (26) of movement of the cursor (27) develops.
- This solution is advantageous because the frame (26) can also have a considerable development in height and must support the weight both of the cursor (27) and of the tubular element (6) carried.
- the transmissions (39) are preferably cardan shafts, which by means of the second gear-reducing device (56) receive the motion from the third motor (38) thus being reciprocally synchronized in order to control the movement of the trolley (17, 18) by means of the just described rack system.

- the trolley is guided by means of four rollers two of which are placed on the upper part and two are placed on the lower part and is fastened by four further auxiliary rollers in an opposite position with respect to the main rollers to prevent overturning.
- the four main rollers support the load on the ground while the side rollers are able to discharge the lateral or longitudinal loads due to the weight of the tubular element or to the movements of the vessel.
- the auxiliary rollers during normal operativeness do not touch the respective guides except in the case in which there are longitudinal acceleration peaks or movements of the ship, impacts, etc.
- the lifting system or cursor driving means (31) consist of two cables (33) that wind on the two winches (32) with at least five safety turns that are maintained also in the case of maximum release of the cable. From the winch the cable (33) passes along first fixed pulleys that are applied on the walls of the vessel itself or on the fixed supporting structure of the whole system. The cable (33) then reaches ( Fig. 43 ) the top first pulleys (34) that are on top of the frame (26) along which the cursor (27) moves.
- the cables will preferably have a diameter of 26 mm and are fastened to the compensator device (86) by means of eyelet or fork systems ( Fig. 50 ).
- the nut and lock nut system allows to adjust the tension of the cables (33) in order to set a relative tension of one with respect to the other that is such as to maintain the compensator device (86) in an approximately horizontal position.
- the encoder system includes an encoder box installed on top of the frame (26) near the first pulleys (34).

- the first body (58) can slide vertically in lifting and in lowering along the stanchion (59) that guides its movement and on which the driving means of the first body (58) supporting the cradles (57) are installed.

- the movement of the second body (84) is of the vertical type in the same way as that of the first body (58) and allows to obtain a prolongation of the movement of the cradles (57) obtaining a movement stroke greater than the one that would be obtainable with the stanchion (59) only.
- the second body (58) can be ( Fig. 38 ) vertically mobile by means of a worm screw system in which an actuator (73) controls by means of a pair of shafts (75) the vertical stroke of the second body (58) along the screws (72).
- a lowering and lifting movement of the cradles (57) is enabled by the interaction of the lifting device (4) with:

- the tilter device (65) is made up of a pair of components of which a first component (68) and a second component (69) which are reciprocally aligned ( Fig. 36 , Fig. 37 ) according to a direction corresponding to the width of the tubular element (6) to be moved.
- the first component (68) and the second component (69) are spaced from each other by a distance greater than the width of the tubular element (6).
- the first component (68) and the second component (69) comprise ( Fig. 41, Fig. 42 ) each a pair of supporting elements (77) which support a rotating arm (78) by hinging.
- the centres of rotation around which the two arms (78) are rotating are reciprocally aligned ( Fig. 36 , Fig.
- the centre of rotation of the arm (78) of the first component is aligned with the centre of rotation of the arm (78) of the second component in such a way that the arms (78) perform a rotation along reciprocally parallel planes.
- the rotation of the arm (78) is controlled by means of a fourth motor (83) which by means of a third gear-reducing device (82) puts in rotation a pair of gears (81) arranged on a same motor shaft.
- Each gear acts on a corresponding toothed portion (80) present on operating wings (79) of the arm (78) that are integral with the arm itself.
- the wing (79) is made in the form of a portion of circular plate, because the rotation that has to be made by the tilter device (65) is not made on an arc of 360 degrees but must follow only a stretch approximately of 180 degrees to take ( Fig. 28, Fig. 29, Fig. 30 ) the tubular element (6) from the lifting device (4) to the following transfer device (3) or vice versa in case of loading of the hold.
- the tubular element (6) is lifted from the hold (14) by means ( Fig. 25, Fig.
- the arm (78) is rotated ( Fig. 30 ) to lift the tubular element (6) from the lifting device (4), which is thus free to go down into the hold again to take out another tubular element while the tilter device (65) lays ( Fig. 47 ) the tubular element onto the transfer device (3).
- the grasp of the tubular element (6) by the tilter device (65) occurs by means of engagement means in the form ( Fig. 41, Fig. 42 , Fig. 37 ) of a retractable third pin (66) placed in correspondence with the arm (78), the third pin (66) of the arm (78) of the first component (68) being movable in a coordinated way with the third pin (66) of the arm (78) of the second component (69):
- the reciprocal approach of the third pins (66) implies the insertion of the third pins (66) into the tubular element (6) from directions opposite to each other, locking the tubular element on the tilter device (65) which can then move in rotation the arms (78) to lay ( Fig. 47 ) the tubular element (6) on the transfer device (3), which for example can carry out the transfer on rails (87) to another zone of the vessel (1).
- the transfer device (3) can be the transfer device of the risers usually indicated by the name of "catwalk" that carries out the transfer ( Fig. 1 ) to a derrick (2).
- the innovative system according to the present invention can advantageously manage in a completely automatic way the main phases of the operation of movement of the tubular elements (6) from the storage zone (14) to the laying zone (2) or vice versa from a loading zone or from a laying zone (2) to the storage zone (14).
- the system according to the present invention preventing suspended load conditions, is able to carry out a completely guided and restrained movement of the tubular elements also allowing, therefore for the automatic transfer of a tubular element from a device to the other, such as from the movement device (5) to the lifting device (4) or from the lifting device (4) to the tilter device or vice versa.
- the movement device (5) is made up of two trolleys, that is to say, a first trolley (17) and a second trolley (18) which are movable in a reciprocally coordinated and synchronized way during the movement phases of the tubular elements.
- a first trolley (17) and a second trolley (18) which are movable in a reciprocally coordinated and synchronized way during the movement phases of the tubular elements.
- Such operating mode is particularly useful during the inspection phases.
- the first trolley (17) and the second trolley (18) are provided ( Fig. 15, Fig. 16 ) with at least one protection basket (61) able to accommodate an operator who, by controlling the respective trolley, can inspect freely and rapidly the tubular elements reaching any position within the storage zone without having to move physically within the storage zone itself but always remaining within the basket (61) placed on the cursor (27) of the trolley (17, 18).
- the two trolleys in an independent way one can carry out the inspection simultaneously from opposite sides of the stack by means of two operators, a first operator on the first trolley (17) and a second operator on the second trolley (18).
- the system according to the present invention also allows to completely automate the inspection phase as the cursor (27) of the trolley (17, 18) can be advantageously provided with visual detection or measurement means to perform operations of automatic supervision of the stored tubular elements (6).
- visual detection or measurement means to perform operations of automatic supervision of the stored tubular elements (6).
- the system can display on a monitor an image of the tubular element (6) on which the anomaly was detected so that the operator can decide whether to catalogue this signal as a false alarm or as a real anomaly or can decide to send to the site an operator who will carry out an in-depth control to establish the cause of the problem and verify whether the tubular element (6) is actually damaged or if it is usable.
- the operator who must carry out the control will not have the need to locate the tubular element in the stacks as the trolley (17, 18) itself will take the operator in correspondence with the position in which the tubular element to be inspected is.
- the lifting device (4) is characterised by having the lower section of its cradles (57) configured according to a telescopic shape. This allows the cradles (57), sized to lift the tubular elements (6), to go down into the hold or into the storage zone (14). This particularity allows to eliminate the need for a further hold elevator to take the tubular elements out of the hold as is necessary in some prior art solutions. In this way, by eliminating a further device from the hold it is possible to obtain a further saving of space in height within the hold which can be advantageously exploited to house a greater number of tubular elements (6) or to reduce the size of the vessel (1), with evident great benefits in both cases.
- the particularity of the different engagement system of the tubular elements that for the movement device (5) is made up of the pins (29, 30) and for the lifting device (4) is made up of the cradles (57), allows for the transfer of the tubular elements between the two devices with the tubular element (6) never being left free to all advantage of the safety of the operation enabling a movement in an always guided and restrained condition of the tubular elements (6).
- the lifting device (4) can thus lift the tubular element (6) out of the hold taking it to the tilter device.
- the tilter device can then take out the tubular element (6) by an engagement system with telescopic pins similar to the engagement system with pins of the movement device (5) that has been previously described.
- the tilter device will lay the tubular element (6) onto the transfer device (3), which in the case of the specific application of the risers on a drilling vessel will be made up of the device usually called "catwalk".
- the transfer device (3) which in the case of the specific application of the risers on a drilling vessel will be made up of the device usually called "catwalk".
- the lifting device (4) and tilter device allows for a completely guided and restrained transfer of the tubular element in conditions of maximum control and safety both for the operators and for the tubular elements.
- the present invention is applicable in the movement of tubular elements (6) on vessels (1) that operate in offshore work conditions.
- the tubular elements can be risers in the case of drilling vessels or pipes in the case of pipe-laying vessels.
- the pipe-laying offshore means are means used to build and lay on the sea bed underwater ducts. These means need to move, during the operations, large quantities of pipes which make up the ducts to be laid on the sea or ocean bed.
- the element to be moved is no longer a composite pipe like the riser but they are real pipes with much variable diameter and lengths.
- the aim is no longer to move the pipes from the hold to a "catwalk" but, in a completely analogous way, to enable their loading into the hold from the support ships dedicated to supply the means with new pipes, or to take out the pipes from the hold to position them on the welding line where are they are pre-assembled and then to draw them and take them onto the launch line where they are connected to the already launched section of pipes to be lowered onto the sea bed.
- the advantages deriving from the application of the present invention are evident.
- the present invention advantageously provides a movement method for tubular elements (6) on a vessel (1) at least in correspondence with a storage zone (14) of the vessel (1) itself or from the storage zone (14) to a feeding zone (2) or vice versa, wherein the tubular element (6) is advantageously always moved in an essentially restrained condition preventing suspended load conditions.
- the movement method includes movement phases of the tubular elements carried out by means of at least one pair of devices of a handling system (3, 4, 5, 65) of the tubular elements (6) and transfer phases of the tubular element (6) from a first device of said handling system (3, 4, 5, 65) to a second device of said handling system (3, 4, 5, 65).
- the transfer of the tubular element (6) from the first device to the second device of said handling system (3, 4, 5, 65) occurs by alternating different types of grasp and transfer means of the tubular element (6).
- the transfer phases from the first device to the second device can comprise:
