    专利说明:

    [1] [0001] The present invention relates generally to system for transporting objectsto ocean structures.
    [2] [0002] Due to the incidence of accidents there are strict limitations regardingacceptable sea conditions when boarding or transporting objects to an oceanstructure such as for example an offshore oil or wind energy platform. This limits the time window for maintenance and repair.
    [3] [0003] These are well-known problems and dangers within the industry, both whentransferring personnel, equipment and supplies to or from an ocean structure. Thesame problem also arises when boarding a larger ship from a smaller boat.
    [4] [0004] To overcome these limitations boats are getting bigger and moresophisticated and the costs of equipment, personnel and fuel, are increasing. Theuse of bigger boats have created new problems that can occur when the boatsaccidentally collides into the platform/foundation structure. lf theplatform/foundation structure and/or its corrosion protection are damaged the COnSeq UenCeS are SGVGFG.
    [5] [0005] Known boarding solutions are for example hanging transport baskets, wavecompensated gangways or cranes mounted on the boat transporting the personnelor equipment to the ocean structure.
    [6] [0006] lt is also known to use boat lifts for use with ocean structures includingone or more mount components for attaching to side regions of a boat. One ormore mechanisms are coupling between the one or more mount components andthe structure for operatively lifting up or down the mount components relative tothe structure. Such boat lift is known from GB2479742 A. 69380
    [7] [0007] A drawback with this systems is that the mechanisms, in the form ofupright members, are welded or otherwise affixed to the ocean structure by aplurality of connection points between the upright members and the structureforming a rigid connection. A further drawback with such system is that itcomprises many components which makes it expensive both to manufacture, aswell as install and/or replace on the ocean structure.
    [9] [0009] A further object of the present invention is to provide a system fortransporting objects to ocean structures which is stable yet less susceptible tobending forces. The bending forces may cause damage to the structure due towear as a result of prolonged use, which in turn increases the risk for operators or crew members.
    [10] [0010] A further object of the present invention is to provide a system fortransporting objects to offshore structures which are cost effective to manufactureand install as well as replace.
    [11] [0011] According to one embodiment the invention provide a system fortransporting object from a sea level position to an elevated position on a structure,wherein the sea level position is movable in relation to the elevated position. The system comprises; - an elongated guide device configured to be arranged to the structure inone end and to extend below the sea level with a second end, - an attachment device configured to be arranged on said object and forattaching said object to the elongated guide device, wherein the attachmentdevice is configured to allow a relative movement between the attachment device and the elongated guide device along a first direction parallel to the 69380 extension direction of the guide device, and to restrict movement along adirection perpendicular to the first direction, - a lifting device configured to transport the object from the sea levelposition to the e|evated position , The system is characterized in that a weight is arranged to the second end ofthe guide device below the sea level for stabilizing the guide device, wherein the second end is a free end and the weight is a free weight.
    [12] [0012] The mass of the weight, the position of the weight and second end of theguide device sufficiently submerged below the sea level provides a stable guidedevice adapted to be used for lifting heavy objects, at the same time as it does nothave to take up as high bending forces. The attachment device allow a movementalong one first direction and restrict movement in a direction essentiallyperpendicular to the first direction. However, a play between attachment deviceand guide device may be present, allowing a limited movement in the directionessentially perpendicular to the first direction. Further, with a system constructedaccording to this embodiment, where the guide device has a free end with aweight for stabilizing the device, the guide device is able to pivot around itsattachment point to the structure and hence move slightly relative the structure.Thus, the guide device withstands less bending forces on the respective parts thanthe previously known transport and boarding structures with a fixed guide member.Thus, such a system is not as susceptible to wear, will have a longer life span andrequire less service than the previous known solutions. Further, with a free weightattached in one end of a guide device it is possible to move the transport systemaway from the structure and to lift the objects at a certain distance from thestructure, thus minimizing the risk of collision between the structure and object tobe lifted during the vertical transportation. Further, the system is cheap tomanufacture since it comprises few parts, a majority of which are standard parts,as well as being cheap to install as well as replace when necessary. 69380
    [13] [0013] According to one embodiment the attachment device is configured forguiding the object from the sea level position to the elevated position along the elongated guide device when transported by the lifting device.
    [14] [0014] To use a separate lifting device to transport the object and only use theattachment devices for guiding the object during the vertical movement is a morereliable solution than previous known art. Further, it is possible to use liftingdevices already present at the structure and thus to create a more cost efficient solution.
    [15] [0015] According to one embodiment the weight is arranged to the second endof the guide device at a position at least 5m below sea level, preferably at least10m below sea level, whereby the guide device is unaffected by motions of thesea.
    [16] [0016] When arranging the weight a certain distance below sea level, thetransporting procedure is simplified since the guide device is kept straight andstretched and stay unaffected of rough seas. The distance below sea level dependon the conditions present at the site where the structure is located. The weightshall be arranged at a depth unaffected by waves and sea current but shall hangfree and not be attached to or rest on the bottom of the sea.
    [17] [0017] According to one embodiment the guide device comprises two parallelarranged guide wires having a distance from each other. Said guide wires are inone embodiment made of steel.
    [18] [0018] Using two parallel arranged guide wires enables two attachment points tothe object to be transported. Thus, it enables hoisting of the object without theobject rotating and swinging. lt is also easier to keep the object horizontal duringlifting.
    [19] [0019] According to one embodiment the distance between the guide wires iskept constant by a beam extending between the guide wires or wherein the weightis made in one piece and extend between the guide wires. 69380
    [20] [0020] A constant distance between the guide wires simplifies the attachmentprocedure when the object is docked to the guide device.
    [21] [0021] According to one embodiment, the attachment device comprises a first and a second attachment device part arranged to grip the respective guide wires.
    [22] [0022] When separating the attachment device in two attachment device parts itis possible to arrange the different parts on suitable positions on the object to betransported. |.e. the attachment device parts may for example be placed onopposite sides of a stern or stem if the object is a boat or vessel. lf more than oneobject is to be attached to the guide device at the same time, for example a boatand a container where only the container is to be lifted, it is preferred that therespective attachment device parts are arranged at the respective object so that itis possible to attach the objects on different horizontal levels.
    [23] [0023] According to one embodiment, the weight comprises two separate blocksconnected by a beam. According to one embodiment, the weight has a mass of 3- 10 tons.
    [24] [0024] A weight having this specific mass is complicated to transport out to thestructure at sea. lt is therefore an advantage if the weight can be made orassembled at the structure. A weight comprising several parts is easier to handleand transport. The weight of the mass is dependent on the type and weight of theobject to be transported. lt may also be chosen to be above a certain mass so thatit stays essentially unaffected by motions of the sea.
    [25] [0025] According to one embodiment, the structure comprises beams or davitsextending from the structure, wherein the first end of the guide device isconfigured to be arranged to the beams or davits.
    [26] [0026] When using beam or davits extending from the structure it is possible tolift the objects at a further distance from the structure, thus further minimizing therisk of collision between the structure and object to be lifted during the verticaltransportation. 69380
    [27] [0027] According to one embodiment a traverse system is arranged on saidstructure configured to transport the object in a direction essentially perpendicular to the first direction when the object is in the elevated position.
    [28] [0028] When the objects has been lifted to the elevated position by the liftingdevice the traverse system may be used to transport the object to a place in thestructure more protected from the weather and the open ocean.
    [29] [0029] According to one embodiment, the lifting device is a crane or a winch,arranged on the structure or configured to be arranged on or connected with theobject.
    [30] [0030] According to one embodiment, the object is a container, equipment, person transporting arrangement, ship or vessel.
    [31] [0031] According to one embodiment, the structure is an ocean based platform. or another vessel or ship.
    [32] [0032] According to one embodiment, the weight is configured to be moveable from its position below the sea level to an elevated position above sea level.
    [33] [0033] ln one embodiment the weight is also moveable in a direction essentiallyperpendicular to the first vertical lifting direction, when the weight is in the elevatedposition. When the weight is moveable it is possible to store both the object and/or the weight when no transportation to or from the structure is needed.
    [34] [0034] The invention is now described, by way of example, with reference to the accompanying drawings, in which:
    [35] [0035] Fig.1a shows a side view of a system according to a first embodiment ofthe invention, wherein a first type object, a boat, is arranged at sea level positionand a second type object, a container, equipment or person transportingarrangement is transported in a first vertical direction from the first type object to an elevated position of the structure. 69380

    [42] [0042] Fig. 4 shows an attachment device comprising a first and second attachment device parts attached to an object.[0043] Fig. 5a-5c shows an attachment device in different positions.
    [44] [0044] ln the following, a detailed description of the invention will be given. lnthe drawing figures, like reference numerals designate identical or correspondingelements throughout the several figures. lt will be appreciated that these figuresare for illustration only and are not in any way restricting the scope of the invenfion.
    [45] [0045] Fig. 1a shows a side view of a system 1 according to the invention,wherein an object 2 in the form ofa boat 2b, transporting another object 2 in theform of a container, equipment or person transporting arrangement 2a, is arrangedin a first position in relation to the system 1. ln the first position, the stem of the 69380 boat 2b is pointing towards a structure 3. lt is of course also possible, but notshown, to direct the stern towards the structure 3. Fig. 1b shows the Fig 1a fromanother side, i.e. showing a rear view of the objects 2a, 2b. The structure 3 is inthis embodiment an ocean based offshore platform. According to anotherembodiment, the structure 3 is another vessel or ship essentially larger than thetransport boat 2b.
    [46] [0046] Fig. 1a and 1b further shows a system 1 for transporting objects, such ase.g. container, equipment or person transporting arrangement 2a or boats orvessels 2b from a sea level position A1 to an elevated position B on a structure 3wherein the sea level position A1 is movable in relation to the elevated position B.The relative movement of the sea level position A1 and the elevated position B isdue to the movement of the sea itself, i.e. due to waves, currents or similar, inrelation to the rigid structure 3. A sea level position A1 is a position which isaffected by the movement of the sea, thus, the position may be at the actual sealevel A0 if the object is a boat, or alternatively both above and below the sea levelif the object is a container or equipment.
    [47] [0047] According to one embodiment, the system 1 comprises a guide device 4configured for guiding an object 2a, 2b from the sea level position A1 to theelevated position B along a first direction parallel to the extension direction of theguide device 4, i.e. between the sea level position A1 and the elevated position B.The guide device 4 is configured to be arranged to the structure 3 in one end andto extend below the sea level A0 with a second end. According to oneembodiment, the first direction is a vertical direction y. According to oneembodiment, shown in figure 1b, the guide device 4 comprises two parallelarranged guide wires 4a, 4b having a distance from each other. The guide wires4a, 4b may be made of steel. According to one embodiment, the wires have adiameter of 60-90mm preferable 70-80mm, most preferably 76mm. According toone embodiment, the guide device 4 is 20-50 m long. According to oneembodiment, the guide device 4 is 30-40m long. According to one embodiment,the distance between the guide wires 4a, 4b may be kept constant by a beam 4cextending between the guide wires 4a, 4b. Alternatively, the distance between the 69380 guide wires 4a, 4b is adjustable by means of distance adjusting device which maycomprise a telescopic beam or other length adjustable solution. The beam may bea metal beam. The distance between the guide wires may be determined by thesize of the object to be transported.
    [48] [0048] According to one embodiment, the guide device 4 is attached to thestructure 3 at a fixation point. This point is located above sea level A0, preferablyabove the elevated position B. The structure may comprise beams or davits 3aextending from the structure 3, wherein the first end of the guide device 4 isconfigured to be arranged to the beams or davits. The end of the guide device 4may not be the actual end of the guide wires 4a, 4b or other embodiments of theguide device 4, however, the fixation point of the guide device 4 in the structure 3defines the end of the guide device 4. ln one preferred embodiment, the guidedevice is pivotably or rotatably attached to the structure in the fixation point. l.e.the attachment allow some relative movement between the guide device 4 andstructure 3.
    [49] [0049] The system 1 further comprises an attachment device 5 configured to bearranged on the object 2a, 2b and for attaching the object 2a, 2b to the guidedevice 4. The attachment device 5 is configured to allow a relative movement ofthe attachment device 5 and the guide device 4 along the first direction betweenthe sea level position and the elevated position, and to restrict movement along adirection perpendicular to the first direction but still allowing a small play betweenthe attachment device and guide device. According to one embodiment, theattachment device 5 is fixedly arranged on the object 2a, 2b. According to oneembodiment the attachment device 5 comprises a first and second attachmentdevice part 5', 5" arranged to grip the respective guide wire 4a, 4b. Theattachment device 5 is further described in figure 4a-4c.
    [50] [0050] The system further comprises a lifting device 8 configured to lift theobject 2a, 2b along the guide device 4 the first direction between the sea levelposition and the elevated position. According to one embodiment, the lifting device6 is a crane or a winch (not shown), arranged on the structure 3. According to one 69380 embodiment, the lifting device 8 is arranged on the object 2a, 2b itself andconfigured to interact with the structure 3 such that a relative movement betweenthe object 2a, 2b and the structure 3 can be generated. For example, a winch orsimilar may be arranged on the object 2a, 2b wherein a wire 8a extending from thewinch may be arranged in or guided via a position in the structure 3, which islocated at a point near the e|evated position. The fastening point for the wire maythus be on the object 2a, 2b itself if there is a guiding point in the structure 3. Uponactivating the winch, the object is pulled from the sea level position towards thee|evated position. When the object 2a, 2b reaches the e|evated position B it canbe attached to fixed straps or other objects. This will enable the lifting device 8 to be released and used to move other items.
    [51] [0051] The system further comprises a weight 6 which is arranged to the secondend of the guide device 4 below the sea level for stabilizing the guide device 4.Hence, the second end of the guide device 4 is a free end and the weight 6 is afree weight, in that the weight 6 itself is connected only to the second end of theguide device 4 and that the second end of the guide device 4 is connected only tothe weight 6. Thus, the free end and free weight is slightly moveable with thestructure and ocean currents in all directions in space. However, the weight ischosen to have a mass so heavy that the free weight and free end is keptessentially stationary in the water. According to one embodiment, the weight 6 hasa mass of 3-10 tons, preferably 5-7 tons, most preferably 6 tons. However, othermasses are also possible since the weight is also dependent on the type andweight of the object to be transported. According to one embodiment, there is nofurther connection points to the guide device 4 between the first end and thesecond end of the guide device 4. As a result, the guide device 4, especially whenin the form of two guide wires 4a, 4b, are kept stretched by the weight 6 attachedat their second ends. According to one embodiment, the length of the guide device4 is such that the weight is arranged to the second end of the guide device 4 at aposition at least 5m below sea level, preferably at least 10m below sea level,whereby the guide device 4 is unaffected by motions of the sea. According to oneembodiment, the weight 6 comprises two separate blocks 6a, 6b connected by a beam, e.g. a steel beam. The respective block may then be connected to a 693801 1 respective guide wire 4a, 4b. The beam further aids to keep the guide wires 4a, 4bat a constant distance from each other. According to another embodiment theweight 6 is made in one piece as a single unit and extend between the guide wires4a, 4b to keep the distance between the guide wires constant.
    [52] [0052] According to one embodiment, both the object 2a, i.e. the container orequipment to be transported as well as the boat 2b may be attached to the guidedevice 4. |.e. one attachment device 5 may be arranged on each object in order toguide both objects when lifted or to moveably attach the second type object 2b, aboat, to the structure when a second type object 2a, a container or similar, isguided by the guide device towards the e|evated position. lf more than one objectis to be attached to the guide device at the same time, for example a boat and acontainer where only the container is to be lifted, it is preferred that the respectiveattachment device are arranged at the respective object so that it is possible toattach the objects on different horizontal levels.
    [53] [0053] Fig. 2a shows a side view of a system according to the invention and fig.2b shows a rear view of the system, wherein the object 2 is a boat or vessel 2b.The boat or vessel 2b is disclosed in a first position at sea level A1 an when lifteda certain distance along the guide device 4 in a first, vertical direction from the sealevel position A1 towards the e|evated second position B of the structure 3. Thesea level position A1 is in this embodiment the actual sea level A0 since the objectis a boat. The boat is arranged in relation to the system 1 so that a side of the boat2b is arranged facing the guide device 4. The boat 2b is flexible attached, invertical direction, to the guide wires 4a, 4b of the guide device 4 by help of theattachment device 5 which is fixed to the boat 2b. The attachment device 5comprises a first and second attachment device part 5a, 5b arranged to grip therespective guide wire 4a, 4b. ln order for the boat 3b to have a free transportationway, the guide wires 4a, 4b are attached in one end to beams or davits 3aextending from the structure 3. The guide wires 4a, 4b are in their other endattached to the weight 6. The connection of the boat 2b to the guide wires 4a, 4benables hoisting of the boat without the boat rotating and swinging. By help of alifting device 8 placed on a platform on the structure 3 and a wire 8a extending 6938012 from the lifting device 8 to the boat 2b, the boat is transported from the sea level tothe elevated position. When the boat is in the elevated position, persons orequipment may safely be embarked from the boat to the structure without riskinginjury. When in its elevated position it is also possible to release the boat 2b fromthe lifting device and secure it to the structure with other means, for exampledavits. lt is the possible to use the lifting device 8 for other purposes.
    [54] [0054] Fig 3a, 3b and 3c shows another embodiment of the system according tothe invention. ln this embodiment the weight 6 is configured to be verticallymoveable from its position below the sea level to an elevated position B2 abovesea level in a first direction y. The elevated position B2 is in this embodimentessentially the elevated position B, but any other elevated position is possible. Atleast one winch 9 or other type of lifting device is arranged to move said weight 6by hoisting the guide wires 4a, 4b. ln one embodiment the weight is lifted a timeperiod after the object is lifted. ln some conditions it is also possible to lift the weight simultaneously with the object.
    [55] [0055] ln one embodiment a traverse system 11 is arranged on the structure 3.The traverse system 11 may comprise one or more horizontally arranged beams11a extending from the structure 3. The traverse system 11 is configured totransport the object, i.e the boat and/or equipment 2a, 2b in a direction xessentially perpendicular to the first vertical lifting direction y when the object 2a,2b is in the elevated position B. l.e. when the boat and/or equipment has beenlifted to the elevated position by the lifting device 8 it can be transported to a placein the structure 3 more protected from the weather and open ocean. ln oneembodiment the weight 6 is also moveable in a direction x essentiallyperpendicular to the first vertical lifting direction y, when the weight is in theelevated position B2. The object 2a, 2b and/or the weight 6 is thus safely storedwhen no transportation to or from the structure 3 is needed. The wires 4a, 4battached to the weight 6 and the wire 8a attached to the object to be lifted 2a, 2bmay run in a system of blocks and tackles 11b to optimize the lifting capacity of thesystem and to enable the horizontal movement. Both the guide device 4 and thelifting wire 8a may, in one embodiment, be attached to a single structure 11a 6938013 moveable in the horizontal direction. Thus, when both the boat 2b and the weight 6is in the elevated position B2, the single structure 11c is moved horizontally. ln oneembodiment, the single structure 11a is fixed in relation to the transverse system11 and the entire transverse system 11 comprising beams is moved horizontally inthe x-direction by a movement device of any kind.
    [56] [0056] Figure 4 disclose an embodiment of the attachment device 5. Theattachment device 5 comprises a first and second attachment device part 5', 5"arranged to grip the respective guide wires 4a, 4b of the guide device 4. Therespective attachment device part 5', 5" are attached to the object 2a, 2b with adistance adapted to the distance between the guide wires 4a, 4b. When the object 2a, 2b is docked to the guide device 4, the respective attachment device part 5', 5catches the guide device and partly grip the respective wire 4a, 4b.
    [57] [0057] According to one embodiment, shown in figures 5a-5c, the attachmentdevice 5 comprises a hook or openable ring 5b arranged in a housing 5a. Thehook 5b is rotatable around a first end by a rotation device 5c for releasableattaching the attachment device 5 around the guide device 4 in the form of e.g. guide wires 4a, 4b.
    [58] [0058] Figure 5a-c shows the hook 5b in a first, second and third position. ln thefirst position, figure 5a, the hook is stored away. ln the second position, figure 5b,the hook is rotated so that it easily catches the guide device and partly grip therespective wire 4a, 4b. ln the third position, figure 5c, the hook is in its lockedposition where a relative movement in a first direction, i.e. a vertical liftingdirection, is allowed and a movement perpendicular to the first direction isrestricted. Within the meaning of a restricted movement, a certain limitedmovement may be allowed due to variations or slight differences between theguide wire diameter and the diameter of the hook or openable ring. A restrictedmovement may also be an entirely restricted movement, i.e. wherein no relativemovement is allowed and the hook or openable ring is locked in relation to the guide wires 4. 6938014
