Description

A System and Method for Transporting an Elongate Element, and a Support Apparatus for enabling same.

TECHNICAL FIELD

[0001] The present invention generally relates to a system and method for transporting an elongate element, and a support apparatus to enable the transportation of the elongate element. In particular the present invention relates to a system, method and associated support apparatus for transporting an elongate element, such as a riser, with a lifting sling attached thereto.

BACKGROUND ART

[0002] Transportation of equipment from a place of manufacture to a place of installation can include many different modes of transportation. This can present a variety of obstacles which need to be addressed to ensure safe transportation of the equipment. These obstacles are compounded when the equipment to be transported is of considerable size. In these situations the logistics in transporting the equipment requires careful planning.

[0003] The oil and gas industry regular requires transportation of large pieces of equipment. In the oil and gas industry it is commonplace for a piece of equipment to be manufactured in one country and then transported to a different country and/or location at sea. This typically requires using a truck to transport the equipment to a port, load the equipment onto a ship, transport it to another port, unload the equipment from the ship and onto another truck, and then either drive it to site, or drive it to another location for storage, or loading onto a specialist vessel before the equipment is taken to its location at sea. This requires multiple lifting loading/unloading events of the equipment, which adds significant time to the transportation process.

[0004] One piece of equipment that fits into the above category is a riser. Risers are relatively long, elongate pieces of equipment used to connect wells with facilities at the ocean surface. To assist with loading/unloading events, each end of the riser is fitted with a shackle type arrangement called a nubbin. The nubbin allows a thick wire sling to be attached to each end of the riser. [0005] A crane connected to the slings can then lift the riser and move it to the required position. In order to save time when loading and unloading the riser, it is highly desirable for the slings to remain with the riser throughout the journey.

[0006] When using a truck to transport the riser, a specialist, extendible trailer is used. This trailer has several wheel sets located at the rear section of the trailer and an extendible frame attached to a front section of the trailer, which is adapted to be connected to a prime mover. The rear section provides a support surface such that once the riser is loaded onto the trailer the sling can be lowered and stored on the trailer while the sling remains connected to each end of the riser. This system works well when the risers do not exceed 23m (75ft).

[0007] However, the oil and gas industry are now using risers which are in excess 27m (90ft) long. The extra length presents additional obstacles to the safe transportation of the risers. In order to transport the riser by road, the trailers arrangements have been lengthened. However, as the distance between the rear supporting section and front of the trailer is now greater, it is difficult to safely support and secure the sling when secured to the riser during transportation.

[0008] As a result of the longer riser, it is not possible to safely transport the riser by road while the sling is still secured to the nubbins. It is therefore necessary to remove the sling once the riser is loaded onto the trailer, and reattach the sling before the riser can be unloaded from the trailer.

[0009] In order to remove the sling specialist equipment is required. For instance, when loading or unloading a riser from the truck at a port/wharf the loading is typically carried out by a crane located near the vessel. When the riser is positioned on the truck, the height of the nubbin to which the sling is attached/is to be attached exceeds the safe working height. In these situations there are no specialist gantries which can be used to allow an operator to safely attach/remove the slings from the nubbins. As such a scissor lift or the like needs to be used to provide the operators with a safe work platform.

[0010] Typically a team is required to ensure a safe environment is provided when removing or attaching of the sling. Assuming the equipment and personnel are available the removal or attachment of the sling from the nubbin may take one to two hours. This needs to be repeated at each end. This adds expense and time when transporting the riser.

[001 1] Also, once the sling is removed from the riser, another truck is required to take the sling to the destination, adding further cost to the process.

[0012] Furthermore, the additional time the truck remains on the wharf impacts the movements around the wharf, can delay other activities around the wharf, and can limit ship movements. As such unloading/loading of risers requires careful planning with the planners at the wharf.

[0013] The preceding discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.

DESCRIPTION OF EMBODIMENTS

[0095] The present invention relates to a system, method and support apparatus for moving/transporting an elongate element from one location to another. In order to manoeuvre the elongate element a sling is secured to each end of the elongate element and a crane (or other lifting means) uses the sling to move the elongate element.

[0096] If the elongate element has not reached its final destination after the first lifting event, it is highly desirable to keep the sling connected to the elongate element. The present invention enables this to happen in a safe and efficient manner.

[0097] The present invention will know be described with reference to several specific embodiments. These embodiments relate to transporting an elongate element which is in the form of a riser. However, as would be obvious to a person skilled in the art the present invention can be easily applied to other elongate elements and is therefore not limited to the transportation of a riser 13.

[0098] According to a first embodiment of the present invention there is provided a system of supporting a sling when transporting a riser 13 using a support apparatus, and a method of using the same. When transporting a riser to its intended location the riser 13 will typically require to be transported by road at some point during the journey. This requires the loading of the riser 13 onto the back of a specialised truck trailer 15.

[0099] The truck trailer 15 is specifically designed for the transportation of risers 13, having a frame which is extendible to accommodate different riser lengths. The truck trailer 15 has a bank of wheels sets 17 at a rear end of the trailer 15, while a front end of the trailer 15 is adapted to be secured to a prime mover (not shown).

[00100] Using a sling 19 a crane (not shown) is used to lift and position the riser

13 on the trailer 15. The sling 19 comprises two cables 21 a, 21 b connected together by a shackle. To assist in securing the sling 19 to the riser, each end of the riser has a nubbin 23 secured thereto. This allows respective ends of the sling 19 to be attached to the riser 13.

[00101] Once the riser 13 is on the trailer the sling is supported on a system of a plurality of support apparatus 12. Each support apparatus 12 comprises a first portion 14, which in the present embodiment is in the form of a saddle bracket 11 .

[00102] As shown in figures 1 to 4 each the saddle bracket 1 1 is in the form of a unitary member comprising a first leg 25 and a second leg 27 interconnected by a web 29. The saddle bracket 1 1 is semi-circular in form.

[00103] The saddle bracket 1 1 comprises a first support portion and a second support portion in the form of a first and a second support channel 31 located at an end of each leg portion 25, 27. Each support channel 31 is adapted to receive and support one of the cables 21 a, 21 b as will be explained below.

[00104] The saddle bracket 1 1 also comprises a lifting device 33 for receiving a lifting means, which in the present embodiment is in the form of a forklift 35. The lifting device 33 is adapted to receive the tines of the forklift 35 such that it can be readily moved and positioned on and off the riser.

[00105] The saddle bracket 1 1 also comprises a first attachment means 37 located on an outer surface 38 of the support channel 31 attached to the first leg 25. An end of a second portion 16 can be attached to the first attachment means 37. The other end of the second portion 16 can be attached to a second attachment means 39 located on an outer surface 41 of the support channel 31 attached to the second leg 27, for reasons which will be described below. The second portion 16 also incorporates a tightening means in the form of a tightening member 43 for tightening the second portion 16 and secure the support apparatus in place.

[00106] Alternatively, the first attachment means 37 and second attachment means 39 may be located adjacent the end of the first leg 25 and an end of the second leg 27 respectively. This will then allow the saddle bracket 11 to be stored such that it rests on the outer surfaces 38, 41 of the support channel 31 of the respective leg 25, 27. [00107] The saddle bracket 1 1 has a layer of rubber 45 secured to the inside surface of the saddle bracket 1 1 , as well as the inside surface of each support channel 31 . This is to minimise slippage of the saddle bracket 1 1 with respect to the riser, and the sling with respect to the support channel 31 .

[00108] An alternative embodiment of the support apparatus 1 12 is shown in figure 5. The support apparatus 1 12 of this embodiment is similar to that of the support apparatus 12. In this regard the same reference numbers will be used to refer to the same components. The differences between the two support apparatus are that the support apparatus 1 12 of the second embodiment provides a first portion 1 14, which is in the form of flexible webbing and does not require a lifting means.

[00109] As with the support apparatus of the first embodiment the support apparatus 112 comprises a second portion 1 16. The second portion incorporating a tightening member 43 so that the length of the second portion is adjustable. When the first portion 114 is placed over the riser, the second portion 1 14 is positioned underneath the riser. A first end of the second portion 1 16 is then connected to a first end portion of the first portion 114, and a second end connected to a second end portion of the first portion 1 14, whereby tightening the tightening member 43 will secure the support apparatus 1 12 in place.

[001 10] The support apparatus 1 12 also comprises a first and second support portion in the form of a first and second support channel 131 . Each support channel 131 comprises a locking portion 147 (only one shown in figure 5). The locking portion 147 is movable from an open position, wherein the sling can be positioned in the support channel 131 , and a closed position, as shown in figure 5, wherein the sling would be retained within the support channel 131 , releasably securing the sling relative to the support apparatus 1 12.

[001 1 1] In operation, the system of the present invention supports the sling on at least on support apparatus allowing the riser to be transported without requiring the sling to be removed while the riser is in transit. The method to support the sling relative to the riser during transportation is depicted in figures 6 to 16. In illustrating the method the first portion 14 of the support apparatus is in the form of the saddle bracket as shown in figure 1 to 4. [001 12] Referring to figure 6, the riser 13 is shown being loaded onto the trailer 15. As can be noted in the figure, the sling 19 is secured to each end of the riser, using a nubbin 23 attached to each end of the riser 13 to facilitate attachment of the sling 19.

[001 13] Once the riser is positioned on the trailer 15, the forklift 35 is used to position a system of four support apparatus in the form of saddle brackets 1 1 along the longitudinal extent of the riser 13, as shown in figures 7 to 9. The saddle brackets 11 are shaped to substantially complement the cross sectional profile of the riser 13 so they may be readily received on the riser. Each saddle bracket 1 1 is positioned to be spaced apart from each other.

[001 14] In this embodiment, as is preferable, the rearmost saddle bracket 1 1 is positioned as close as possible to the forward most wheel set of the rear bank of wheels sets 17.

[001 15] Once each saddle bracket 1 1 is in position the second portion is passed under the riser 13 and the ends of the second portion are respectively secured to the first attachment means 37 and second attachment means 39. The tightening member 43 is then tightened to secure each saddle bracket 1 1 in place, as shown in figure 10 and 1 1.

[001 16] Once each saddle bracket 1 1 is secured, the crane can begin to lower the sling 19. As the sling 19 is lowered, one cable 21 a is caused to fall on one side of the riser 13, while the other cable 21 b is caused to fall on the other side of the riser 13.

[001 17] Referring to figures 12 to 15, as the sling 19 is lowered the cables 21 a, 21 b are received in respective support channels 31 of each saddle bracket 1 1. Further lowering results in the system of -four saddles 1 1 receiving the cables 21a, 21 b in the support channels 31 either side of the riser 13. Figure 16 shows the further the step of causing one of the cables (21 b) to double over so that the ends of the cables 21a, 21 b which are shackled together remain in close proximity.

[00118] When the sling 19 is supported in the support channels 31 the sling may be detached from the crane. The trailer 15 may then be towed away and taken to its next destination. As the sling 19 is supported by the system of support apparatus in the form of saddle brackets 1 1 , the sling is able to remain attached to the riser 13 while being transported by road. When the riser reaches its destination all that is required to remove the riser is to attach the sling 19 to another crane and remove the riser 13. The system of saddle brackets 1 1 eliminate the need to remove the sling 19 from the riser when transporting the riser 1 1 . This provides significant advantages in time and resources.

[001 19] While it is expected that the weight of the sling will be sufficient to retain the sling in position relative to the saddles, one or more ratchet straps (not shown) may be used to secure the sling relative to the riser. When the riser reaches the destination the ratchet straps will need to be removed before the crane commences lifting the riser. Alternatively, a locking portion can extend across the first and second support portions to releasably secure the sling relative to the support apparatus.

[00120] When transporting the riser between lifting events and the sling used for lifting the elongate element is not in use, each support apparatus remains releasably fitted to the riser, and is supported on the support portions of the support apparatus. In this arrangement the sling is supported along the length of the riser, allowing the riser to be transported while the sling is not in use, but still attached to the riser.

[00121] The above system, apparatus and method are described with reference to the support apparatus comprising a saddle bracket, as shown in figure 1 to 4. A similar method is also applied when using the support apparatus of figure 5. The only difference between the two methods is that a lifting device such as a forklift is not required to position the first portion 1 14 of the support apparatus 1 12 in position.

[00122] It is to be noted that the present invention is not limited to this application. The present invention can easily be adapted to be used in the transportation of any elongate element without departing from the scope of the present invention.

The present invention is not to be limited in scope by any of the specific embodiments described herein. These embodiments are intended for the purpose of exemplification only. Functionally equivalent products, formulations and methods are clearly within the scope of the invention as described herein.

[00124] Reference to positional descriptions, such as lower and upper, are to be taken in context of the embodiments depicted in the figures, and are not to be taken as limiting the invention to the literal interpretation of the term but rather as would be understood by the skilled addressee.

[00125] Throughout this specification, unless the context requires otherwise, the word "comprise" or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
