Description

FIELD OF THE INVENTION [ 01 ] The invention relates to a hoisting system comprising a plurality of hoist elements to be hoisted; a winch system comprising a cable or chain to allow hoisting hoist elements of the plurality of hoist elements; and a plurality of coupling members, each coupling member being configured for coupling a hoist element of the plurality of hoist elements to the cable or chain of the winch system.
BACKGROUND OF THE INVENTION [02] A hoisting system of the field of the invention is, for instance, employed in a fall-pipe system installed on a marine vessel for placing blocks of rock and/or stone on a sea bed. Such marine vessel and associated fall-pipe system are used to place rock and/or stone at depths of several hundreds of meters below sea level to cover, for instance, oil pipes so that such pipes remain in place and are protected on the sea bed.
[03] In the hoisting systems of such fall-pipe systems, fall-pipe sections as hoist elements and collectively providing a fall-pipe are in a separate process attached to cables or chains of the hoist system and in this fashion stored in this configuration on the marine vessel. Subsequently, the marine vessel is moved to the location where the fall-pipe is to be used, and the fall-pipe is lowered towards the sea bed for placing rock and/or stone. The fall pipe sections pre-attached to cables or chains are inconvenient to store on the marine vessel (and elsewhere as well), and inconvenient to handle when lowering the fall-pipe below sea level.
[ 04 ] Having to pre-attach fall-pipe sections to cable or chains of the hoisting system also proves to be very inflexible as the fall-pipe systems is to be used for placing rock and/or stone on the sea bed at various depths. The fall-pipe sections pre-attached to the cables or chains of the hoisting system can only be prepared for one length of fall-pipe. Therefore, the length is to be adapted on the marine vessel or the fall-pipe has to be used at the prepared length, which both are very cumbersome.
SUMMARY OF THE INVENTION [05] It is an objective of the invention to provide a hoisting system that can, for instance, be used for a fall-pipe system on a marine vessel for providing a required length of fall-pipe on the marine vessel itself.
[ 06 ] It is another or alternative objective of the invention to provide a hoisting system of which the hoist elements, fall-pipe section in the case of a fall-pipe system, can be readily coupled or decoupled with the winch system of the hoisting system.
[ 07 ] At least one of the above objectives is achieved by a hoisting system comprising
- a plurality of hoist elements to be hoisted;
- a winch system comprising a cable or chain to allow hoisting hoist elements of the
-2plurality of hoist elements;
- a plurality of coupling members, each coupling member being configured for coupling a hoist element of the plurality of hoist elements to the cable or chain of the winch system; and
- a coupling station configured for automatically coupling or decoupling a hoist element of the plurality of hoist elements and the cable or chain of the winch system through a coupling member of the plurality of coupling members, and comprising a first guiding unit configured for guiding the cable or chain of the winch system through the coupling station and a second guiding unit configured for guiding the hoist element through the coupling station, the first and second guiding units being coupled to provide synchronization of a travel speed of the cable or chain of the winch system and a travel speed of the hoist element guided by the second guiding unit, and being configured and arranged to guide the cable or chain of the winch system and the hoist element guided by the second guiding unit towards each other or away from one another and to allow for automatic coupling or decoupling, respectively, of the hoist element and the cable or chain of the winch system.
[08] The machine implemented automatic coupling and decoupling is carried out without the involvement of persons at or near the coupling station, which increases safety and prevents human error. Storage of the material is more compact as compared to known systems since hoist elements and cables or chains of the winch system are stored seperately. Storage of hoisting elements coupled to cables or chains requires more space. Hoisting elements not coupled to cables or chains can also be stored in a vertically stacked manner, which provides more flexibility in the lay-out of the whole system. The hoisting system further provides more flexibility in a distance between coupling positions of neighbouring hoisting elements on the cable or chains of the winch system. If implemented in a fall-pipe system of, for instance, bottomless buckets as hoisting elements on a marine vessel for placing rock on the sea bed, such distance can be varied in dependence on local water currents.

- 3the chain is guided over one or more sprocket wheels.
[13] In an embodiment each holding element comprises a protruding element that protrudes in a direction transverse to the holding loop and is configured and arranged for, in use, bearing the pin of a coupling member secured to a hoist element held by the holding element.
[14] In an embodiment the second guiding unit comprises first and second holding loops of a cable or chain, the first and second holding loops with their respective at least one holding element being configured and arranged to cooperate to hold a single hoist element.
[15] In an embodiment the coupling station comprises a third guiding unit configured and arranged to cooperate with the second guiding unit to urge a hoist element guided by the second guiding unit in a position with respect to the cable or chain of the winch system to allow for automatic coupling or decoupling, respectively, of the hoist element and the cable or chain of the winch system, optionally the third guiding unit being coupled with the second guiding unit to synchronize to the travel speed of the hoist element.
[16] In an embodiment the third guiding unit comprises an urging loop of a cable or chain, which urging loop carries at least one urging element secured to the cable or chain of the urging loop, which at least one urging element is configured to cooperate with the second guiding unit to urge a hoist element guided by the second guiding unit in the position with respect to the cable or chain of the winch system to allow for automatic coupling or decoupling, respectively, of the hoist unit and the cable or chain of the winch system.
[17] In an embodiment the urging loop comprises a continuous loop of a chain, and the chain is guided by one or more sprocket wheels.
[ 18 ] In an embodiment the at least one holding element carried by the cable or chain of the second guiding unit and the at least one urging element of the cable or chain of the third guiding unit, in use, cooperate for urging the hoist element in position for automatic coupling or decoupling of the cable or chain of the winch system and the hoist element.

DETAILED DESCRIPTION OF EMBODIMENTS [ 27 ] Figure 1 shows a schematic large-scale view of a marine vessel 10 provided with a fall pipe system 100 according to the invention. The vessel is travelled to a location where stone and/or rock is to be placed on the bottom of the sea. The stone and/or rock may be
- 5taken with the vessel, provided by another vessel or supplied in another suitable manner. At the desired location the stone or rock is provided to the sea bed using the fall pipe system. The blocks of stone and/or rock R are placed at a sea depth SD of, for instance, 1,500 meter. Figure 1 also shows the influence of dynamic loads due to, for instance, water currents CD1 and CD2. The example of figure 1 shows one current closer to sea level in a direction CD1 and another water current near to the sea bed SB in an opposite direction CD2.
[28] Figure 2 shows part of the marine vessel 10 of figure 1 on which a fall pipe system 100 is arranged. A fall pipe made up of various fall pipe sections 110 suspends down from the vessel through a shaft 11 (moon pool) in the vessel to a large depth just above a sea bed SB. Each fall pipe section 110 is configured as a bottomless bucket. Blocks of stone and/or rock R are provided by a conveyer 12 arranged on the vessel to a top end of the fall pipe and subsequently drop down the tubular fall pipe of cooperating bottomless buckets (tubular fall pipe section) 110, as indicated by unlabelled arrows shown above the conveyer and within the fall pipe. The blocks of stone and/or rock R then leave the last fall pipe section (bottomless bucket) 110L of the fall pipe to be positioned on the sea bed SB.
[ 29 ] A driver arrangement 140 is provided at the end of the fall pipe for positioning the end of the fall pipe at the correct position above the sea bed. The driver arrangement comprises drivers 141 for positioning the driver arrangement together with the end of the fall pipe along the sea bed SB as indicated by arrows D. The driver arrangement further has a shaft 142 for accommodating the fall pipe and/or for passing blocks of stone and/or rock from the end of the fall pipe towards the sea bed. The driver arrangement is shown to be attached to the last fall pipe section 110L, but it can also be attached to a fall pipe section further up the fall pipe.
[30] The bottomless buckets 110 are each coupled to chains 251 so as to, in cooperation, make up the fall pipe. The chains also serve to lift and lower the file pipe through shaft 11 using winch system 250 as part of the hoisting system 200 on the marine vessel 10. To couple and decouple individual bottomless buckets (hoist elements) 110 to the chains 251, the hoisting system is provided with a coupling station comprising first and second guiding units 210, 220. In the coupling station 200, individual bottomless buckets 110 (which may generally also be referred to as hoist elements to be hoisted by hoisting system 200) can be added and coupled to the chains 251 at the top end of the fall pipe when the fall pipe is lowered, and decoupled and removed again when the fall pipe is being lifted. The chains are each a chain 250 of links 251a, and each link has a central opening.
[ 31 ] The coupling station in the embodiments shown in the figures serves to both automatically couple bottomless buckets to the chains when the fall pipe system is being lowered, and to automatically decouple bottomless buckets from the chain when the fall pipe system is being raised. The coupling station has a first guiding unit 210 in the form of sprocket wheels 212 for guiding the chains 251 of the winch system 250 through the coupling station. Each chain is guided by one sprocket wheel 212 in the embodiment shown.
[32] The bottomless buckets are loaded onto a second guiding unit 220 for guiding
-6the bottomless buckets through the coupling station. The second guiding unit comprises first and second continuous holding loops of a chain 221 that are each guided over sprocket wheels 222. Alternatively, the holding loops may have a cable or any other suitable means to make a holding loop. The holding loop carries one or more holding elements 223 secured to the chain 221, each holding element being configured to allow holding a bottomless bucket 110. The first and second holding loops of the second guiding unit 220 with their respective holding elements 223 cooperate to hold a single bottomless bucket 110. The first and second guiding units 210, 220 are coupled to provide synchronization of the travel speed of the chain of the winch system and the travel speed of the hoist element held and guided by the second guiding unit 220. Further, the first and second guiding units 210, 220 are configured and arranged to guide the chain 251 of the winch system and the hoist element 110 held and guided by the second guiding unit towards each other (or away from one another at decoupling) and to allow for automatic coupling (or decoupling) of the hoist element and the chain 251.
[33] The bottomless buckets 110 each have two coupling members 150 for coupling the bottom less buckets to the chains 251 of links 251 a of the winch system 250. Each coupling member is secured to a bottomless bucket and provides for releasable locking engagement with the chain of links. Each coupling member 150 comprises a pin for insertion into the central opening of a link 251a of the chain 251 of links when the coupling member is coupled with the chain. A coupling member 150 is coupled with the chain by insertion of a distal end 151a of the pin 151 into the central opening of a respective link 251 a when a part of the chain of links comprising the respective link is guided over a respective sprocket wheel 212 so that it is in a bend configuration. The bend configuration allows ready insertion of the pins 151 into the central opening of such links by lowering the bottomless bucket with the pins 151 of its coupling members 150 into alignment with the respective links 251a into which the respective pins are to be inserted. The holding elements 223 carried by the guiding loops of the second guiding unit 220 each comprise a protruding element that protrudes in an outside direction transverse to the holding loop to bear the pins 151 of the coupling members 150 secured to the bottomless bucket 110 held by the holding elements 223.
[34] To further assist in achieving automatic coupling of the coupling members 150 secured to the bottomless buckets 110 and the chains 251 of links 251a, the coupling station comprises a third guiding unit 230. The third guiding unit cooperates with the second guiding unit 220 to urge a bottomless bucket held and guided by the second guiding unit in a position with respect to the chain 251 of the winch system to allow for automatic coupling (or decoupling) of the bottomless bucket and the chain. The third guiding unit is coupled to the second guiding units to synchronize to the travel speed of a bottomless bucket held and guided by the second guiding unit.
[ 35 ] The third guiding unit 230 comprises continuous first and second urging loops of a chain 231 carrying one or more urging elements 233 secured to the chain of a respective urging loop. Each urging element cooperates with the second guiding unit 220 to urge a
- 7bottomless bucket held and guided by the second guiding unit in the required position with respect to a respective chain 251 of the winch system 250 to allow for automatic coupling (or decoupling) of the bottomless bucket and the chain. The chains 231 of the urging loops of the third guiding unit are guided by one or more sprocket wheels 232. The holding elements 223 of the second guiding unit 220 and the urging elements 233 of the third guiding unit 230 cooperate for urging a bottomless bucket 110 in position for automatic coupling (or decoupling) of the chains 251 and the bottomless bucket 110. Each urging element comprises a protruding element that protrudes in an outside direction transverse to the respective urging loop, and pushes onto a pin 151 of a coupling member 150 secured to a bottomless bucket held and guided by the second guiding unit. The first holding and urging loops of the second and third guiding units, respectively, together, and the second holding and urging loops of the second and third guiding units, respectively, together cooperate for urging a single bottomless bucket in position with respect to the chains 251 of the winch system 250. The pins 151 secured to the bottomless buckets 110 are held in between respective holding elements 223 and urging elements 233 to urge and insert the pins into central openings of respective links 251a of the chains 251 of links for coupling of a bottomless bucket and the chains.
[36] Coupling of a coupling member 150 secured to a bottomless bucket 110 proceeds automatically when the fall pipe and its bottomless buckets are lowered, and decoupling also proceeds automatically when the fall pipe and its bottomless buckets are raised. The sprocket wheels of the first, second and third guiding rotate in reverse directions to achieve decoupling as compared to their rotation direction to achieve coupling. Correspondingly, the chains of the winch system and the second and third guiding units also travel in opposite directions for decoupling as compared to their travel direction for coupling.
[37] To achieve coupling a pin 151 of a coupling member 150 is inserted into a central opening of a link 251a of a chain 250 of links. The coupling station comprises a sprocket wheel 212 for guiding the chain 251 of links 251a of the winch system 250, and is configured for automatically providing locking engagement of a coupling member 150 secured to the bottomless bucket 110 to the chain 251 or releasing locking engagement of the coupling member from the chain while the chain is guided over the sprocket wheel. The sprocket wheel 212 in the embodiment shown holds every other link of the chain 251 of links 251a when guided over the sprocket wheel to align a link neighboring links held by the sprocket wheel such that the opening surface of the central opening of such link in between links held by the sprocket wheel 212 is directed perpendicular to the rotation axis of the sprocket wheel. This allows ready insertion of the pin 151 of a coupling member 150 into the opening of such link 251a. The circumference length of the sprocket wheel 212 may generally correspond to 4-12 positions for holding links 251a by the sprocket wheel, optionally 6-10 positions, or 8 positions as shown in de embodiment of the figures.
[38] The pin 151 of the coupling member 150 comprises a distal end 151a with respect to the bottomless bucket 110 and a hook-shaped portion at the distal end as is
- 8specifically shown in figures 6A and 6B. The hook-shaped portion is shaped such that it allows insertion of the pin into the central opening of a link 251a of the chain 251 of links of the winch system 250 when a part of the chain of links comprising the respective link is in a bend configuration when guided over a respective sprocket wheel 212. The configuration of the hook-shaped portion provides locking engagement with the chain when the part of the chain of links comprising the respective link is in a straight position when in a suspended position below the respective sprocket wheel. The pin 151 and its coupling member 150 is geometrically locked to the chain in a straight configuration of the chain. The hook-shaped portion of the distal end 151a of the pin 151 allows also ready withdrawal of the pin from the central opening of a link 251a when a portion of the chain comprising the respective link is again guided over a respective sprocket wheel when the fall pipe and its bottomless buckets are raised. The shape of the bottom portion of the hook-shaped portion of the pin 151 corresponds to the shape of the top portion of the links of the chains of links. Alternatively, the shape of the top portion of the hook-shaped portion of the pin 151 corresponds to the shape of the bottom portion of the links. The width WP of the bottom (or top) portion of the hook-shaped part corresponds to a width WL of the links of the chain.
[39] Figures 7A, 7B and 7C show that the coupling member 150 further has two bend-spring elements 152 to catch around a link 251a to hold a link part of the respective link in between the pin 151 of the coupling member 150 and the bend-spring element 152. The bend-spring elements 152 are arranged on opposing sides of the coupling member 150. A bend-spring element only allows deflection in a direction transverse to a longitudinal direction of the pin 151 and a longitudinal direction of the chain 251 of links in a state when the coupling member is in engagement with the chain of links as is depicted by the arrows in figures 7A, 7B and 7C. The bend-spring element comprises a strip-like portion to allow for such deflection. The bend-spring element 152 has a distal end 152a with respect to the bottomless bucket 110, which has a catch side for catching around a link and a shape of the catch side corresponds to the shape of the link part to be held by the bend-spring element. The width WC of the catch side corresponds to the thickness TL of the links.
[40] The bend-spring elements 152 allow for another releasable locking engagement of the coupling member 150 to the chain of links. The sprocket wheels 212 of the first guiding arrangement 210 comprises flange portions 213 that cooperate with a bend-spring element 152 when the bottomless bucket 110 with its coupling member 150 and the chain 350 of links 351a are guided by the second guiding unit 220 and first guiding unit 210, respectively, through the coupling station 200. The flange portions 213 provide deflection of the bend-spring elements to allow the bend-spring elements to catch around a link of the chain of links.
