Definitions

  • the invention concerns a fluid transfer system and a method for transfer of cryogenic hydrocarbon based fluid from a structure to another, for example from a floating production facility for liquid natural gas (FLNG) to a liquid natural gas carrier (LNG carrier).
  • the fluid transfer system comprises one or more transfer hoses and a support structure for supporting the hose(s).
  • the transfer hose(s) comprises a first hose end for fluid communicating connection to the receiving structure and a second hose end for fluid communicating connection to the supplying structure
  • the support structure comprises a column in which a first longitudinal end is attachable to one of the supplying structure and the receiving structure and a support arm connected to the other longitudinal end of the column.
  • WO 02/008116 A1 or WO 2012/028561 A1 describing systems for transferring a load from a ship-based production and storage units to dynamically positioned shuttle tankers.
  • Such systems comprises a loading hose which, during a loading operation, extends between an end of the ship-based unit and a bow manifold on the tanker, and which is stored on the ship-based unit when not in use.
  • the system according to the latter publication is configured for allowing separations between the ship-based units to the tankers of about 250 to 300 meters at least partly due to a particular arrangement of buoyancy elements on the loading hose.
  • cryogenic hydrocarbon containing fluids such as LNG in a sufficiently reliable way.
  • cryogenic transfer operations faces additional challenges which affect the functional features of the transfer systems since the transfer of cryogenic hydrocarbon containing fluids involves hazard assessments setting significantly higher security requirements compared to more traditional transfer systems for non-cryogenic fluids.
  • the invention is to be used in a situation where the transfer of fluid occurs between two structures arranged side by side.
  • the present invention concerns a fluid transfer system for transfer of cryogenic hydrocarbon based fluid from a supplying structure to a receiving structure.
  • the fluid transfer system comprises at least one flexible transfer hose for transferring fluid between the supplying structure and the receiving structure, which transfer hose(s) comprises a first hose portion having a first hose end for fluid communicating connection with the supplying structure and a second hose portion having a second hose end for fluid communicating connection with the receiving structure, and where the other of the two ends of the second hose portion is arranged in fluid communication with the end of the first hose portion other than the first hose end, a support structure for supporting the at least one transfer hose, wherein the support structure comprises a column and a support arm, at least one transfer line fixed in one end to a hose end connector unit, which the connector unit is connected in fluid communication with the second hose end, and a first vertical positioning means fixed to the support structure, which vertical positioning means is configured to guide the at least one transfer line in order to, during use, vertically position the second hose end
  • the at least one of the supplying structure and the receiving structure may be submersed in a body of water during use.
  • the transfer hose, or at least one of the transfer hoses may be made of a flexible material.
  • the connector unit may preferably comprise a hose end connector valve and a hose end coupler valve, wherein the hose end connector valve and the hose end coupler valve are connected in fluid communication and the at least one transfer line is attached to the hose end connector valve.
  • the transfer system further comprises a second vertical positioning means attached to the support system and configured to guide the at least one middle hose portion line in order to, during use, vertically position the border region.
  • the length of the border region is normally below 10 % of the total length of the transfer hose and is normally located a distance from the second hose end which exceeds at least 10 % of the total length of the transfer hose, more preferably at least 20 % of the total length, for example 40 % of the total length.
  • the border region may comprise means such as a hook for attachment of the middle hose portion line.
  • the first hose portion and the second hose portion are for example of equal or near equal lengths.
  • the second hose portion extends along at least the length of the column when the transfer system is in the storage configuration.
  • border region is, in the storage configuration, in an elevated position relative to the first hose portion, and the first hose portion extends along at least the length of the column.
  • the support arm is, in the storage configuration, pivoted into an erect position relative to a direction perpendicular to the longitudinal length of the column.
  • the fluid transfer system is configured so that the hose obtains a W-configuration when the first and second hose ends is attached in fluid communication with their respective supplying and receiving structures and the second vertical positioning means has positioned the at least one middle hose portion line such that the border region is in an elevated position relative to the vertical position of the first hose end and/or the second hose end.
  • the W-configuration and the flexible properties of the hose ensure vertical and lateral compensations as a response to large relative height changes between the supplying structure or FLNG and the receiving structure or LNG carrier. Such compensations inter alia reduce the risk of introducing large dynamic loads on the second connection assembly while the support system in in a static position.
  • the first and second hose portion may act as an elevation compensating hose and a dynamic hose, respectively.
  • the elevation compensating hose enables adjustment of the height of the border region in order to secure optimum working conditions for the dynamic hose, as well as providing added horizontal capacity, while the dynamic hose enables absorption of the major part of the movements of the LNG carrier with no or highly reduced introduction of large dynamic loads on the second connection assembly.
  • the particular W-configuration helps in ensuring an effective drainage of at least the second hose portion during situations when the second hose portion and the second hose end are suspended downwardly from the middle hose portion line, thereby draining any fluid contained in this part of the hose.
  • the transfer system further comprises at least one guiding line attached at least indirectly to the hose end coupler valve and a third vertical positioning means attached to the support system, the third vertical positioning means being configured to guide the at least one guiding line in order to, during use, vertically position the second hose end and the hose end connector unit towards corresponding manifold connectors in a second connection assembly arranged at the receiving structure.
  • the total downward directed force experienced by the part of the line attached at the second hose end is larger than any downward directed force experienced by the part of the line situated directly above the supplying structure during use.
  • the term "downward" is herein defined as the direction parallel to the column and directed towards the columns first longitudinal end. This particular weight distribution ensures that the second hose portion does experience a downward directed force during coupling and transfer procedures.
  • the total downward directed force experienced by the part of the line attached at the second hose end, excluding the downward force added by the weight of the hose end coupler valve, is preferably smaller than any downward directed force experienced by the part of the line situated directly above the supplying structure during use.
  • the first vertical positioning means may comprise at least one sheave and at least one counter weight, wherein the at least one counter weight is attached to the transfer line such that the resulting downward force at least counteracts the downward force acting on the end of the transfer line fixed to the hose end connecter unit. This downward force is set by the combined weight including the weight of the second hose end and the hose end connector unit.
  • the support arm comprises a first support arm and a second support arm pivotally connected to the first support arm.
  • the at least one middle portion line may be connected to the first support arm and the at least one transfer line may be connected to the first support arm and second support arm.
  • the at least one guiding line may be connected to the first support arm and the second support arm.
  • the fluid transfer system comprises at least two transfer hoses suitable for transferring fluid between the supplying structure and the receiving structure, wherein, during use, at least one of the at least two transfer hoses is/are transferring fluid in liquid form in a predetermined direction and at least one of the at least two transfer hoses other than the liquid transferring hose is/are transferring fluid in gaseous form in a direction opposite to the predetermined direction for the fluid in liquid form.
  • This liquid form fluid for example liquid natural gas or liquid petroleum gas, is preferably kept at temperatures below 240 K.
  • the present invention also concerns a method suitable for transferring cryogenic hydrocarbon based fluid from a supplying structure to a receiving structure using a fluid transfer system in accordance the above mentioned features, including a second vertical positioning means (40,41,43) attached to the support system (100).
  • the method comprises at least some of the following steps:
  • the method may also comprise the following step:
  • a single transfer hose 60 is shown.
  • the number of hoses to be installed in fluid communication between a FLNG 70 and a LNG carrier 80 may vary according to the specific needs, and in the particular case of transferring LNG it is considered useful to employ at least two hoses 60, in which at least one is dedicated for the transfer of LNG from the FLNG 70 to the LNG carrier 80, and at least one is dedicated for the transfer of NG from the LNG carrier 80 to the FLNG 70.
  • the hose 60 is shown to comprise a first hose end 63b connected to the FLNG 70 and a second hose end 63a connected to a second connection assembly 90 on the LNG carrier 80.
  • the hose(s) 60 is/are supported in respective hose guides 19 in the form of a funnel shaped guiding channel to limit the lateral movements of the hose 60 during transfer.
  • the hoses 60 are installed into respective hose supports 17 in the form of a guiding channel to enable guidance of the second hose ends 63a safely into fluid communicating engagement with a LNG manifold tube 16 in the LNG manifold 90.
  • each hose 60 may be conveniently defined as comprising a first hose portion 61 extending from the location where the hose 60 leaves the FLNG 70 to near the top of the peak within the W configuration, and a second hose portion 62 extending from near the top of the peak to the position where the hose enters the LNG carrier 80.
  • a middle hose portion 64 is defined as the curved part forming the peak within the W configuration. In Figure 1 this middle hose portion 64 is shown in an elevated position after having been lifted by a middle hose portion line 42 at an attachment point 45.
  • the position of the middle hose portion 64 may be altered, for example as a response to any height differences between the FLNG 70 and the LNG carrier 80.
  • This particular W configuration thus gives the advantage that the first hose portion 61 near the FLNG 70 enables easy compensation of the overall height difference between the two structures 70,80, while the second hose portion 62 near the LNG carrier 80 effectively absorbs any relative movements, thus providing control of the movement induced forces transferred to the LNG manifold 90.
  • the LNG manifold 90 is to a larger degree protected from excessive dynamic loads / stresses compared to systems using rigid ducts and swivels.
  • the second hose end 63a at the LNG carrier side is connected to the LNG manifold 90 by a hose end connector unit 91 in leak free fluid communication with a manifold connector 15, for example by use of a standard flange connection.
  • the connector unit 91 further comprises a hose end connector valve 13 (or hose end valve) and a hose end coupler valve 14. Further, the manifold connecter 15 is connected in fluid communication with the LNG manifold tube 16.
  • connection / disconnection between the LNG manifold 90 and the hose end connector unit 91 takes place between the hose end coupler valve 14 and the manifold connector 15, and an emergency disconnection take place between the hose end valve 13 and the hose end coupler valve 14 (see further details below).
  • the hose end connector unit 91 may include hose end guide means 94,102 arranged in a position above the LNG manifold 90. Further, manifold receiving means 71 may be arranged above the end of the LNG manifold tubes 16 for receiving the hose end guide means 94,102. During connection of the hose end coupler valve 14 to the manifold connector 15, a guiding line 35 guides the hose end guide means 94,102 into the manifold receiving means 71. The load of the hose 60 is thus transferred to the manifold receiving means 71 prior to the actual connection between the connector unit 91 and the manifold connector 15.
  • the guiding line 35 and the middle hose portion line 42 are shown connected to the FLNG fixed support structure 100.
  • the support structure 100 is in Figure 2 in installation mode, that is where both the first support arm 5 and the second support arm 8 extends towards the LNG carrier 80 in a direction transverse to the column 1.
  • the end of the second support arm 8 is located above or almost above the LNG carrier 80, thereby allowing support for the transfer hose 60 over the entire gap between the two structures 70,80.
  • a controlled vertical positioning of the second hose end 63a is obtained by connecting the guiding line 35 via first and second hose end line sheaves 37, 38 to the second support arm 8, and via third and fourth hose end line sheaves 34, 36 to the first support arm 5.
  • lifting/lowering means such as one or more suitable winches 33 located on or near the column 1 provides the necessary outpay and retrieve of the guiding line 35.
  • a transfer line 27 is connected via first and second transfer line sheaves 30, 31 to the second support arm 8, and via sheaves 28, 29 to the first support arm 5.
  • Lifting/lowering means such as a transfer line winch 23 and/or a counter weight 22 located at the column 1 provides outpay and retrieve of the transfer line 27 for the lifting and lowering of the second hose end 63a.
  • One important difference in configuration near the second hose end 63a between the guiding line 35 and the transfer line 27 is their connection to the hose end coupler valve 14 and the hose end valve 13, respectively (see Figure 4 ).
  • the embodiment shown in Figure 2 includes a counter weight system 22-26 comprising a counter weight 22 and a transfer line winch 23 attached to the transfer line 27, a counter weight sheave 24 attached to the counter weight 22, receiving the transfer line 27, a counter weight guiding cylinder 26 limiting the lateral movement of the counter weight 22 and a counter weight end stop 25 limiting the axial movement of the counter weight 22.
  • the counter weight system 22-26 provides additional control of the vertical positioning of the second hose end 63a as will be explained in further details below.
  • the vertical positioning of the middle hose portion 64 is performed by outpaying and retrieving the middle hose portion line 42 using the above mentioned first middle hose portion line sheave 41, second middle hose portion sheave 43 and middle hose portion winch 40, all situated at the first support arm 5.
  • Figure 3 shows another embodiment of the inventive transfer arrangement with an alternative type of counter weight system, where figure 3a is illustrated in a storing position.
  • the second hose end 63a is disconnected from LNG manifold 90 on the LNG carrier side.
  • the first support arm 5 is pivoted into an erect position and the middle portion 64 of the hose 60 is in an elevated position relative to both the first and second hose portion 61, 62.
  • Both hose portions 61,62 are therefore running approximately parallel with the column 1, thus allowing effective drainage of any remaining fluids / particulates inside the hose 60.
  • the second support arm 8 is folded downwards from the first support arm 5 with the free end of the second support arm 8 pointed downward, also in parallel with the column 1.
  • Figure 3a further shows a hose end storing connector 105 for holding / locking the second hose end 63a when the transfer arrangement is in the storing position.
  • first and second support arms 5,8 should now be in a position where the second hose end 63a is directed away from the FLNG 70, and where its vertical position (see Figure 3d,3e ) is within reach of the LNG manifold 90. If this is not the case both the pivoting of the first and second support arms 5,8 and/or the vertical positioning of the hose 60 by the lines 27,35,42 may be adjusted until the second hose end 63a reaches a position sufficiently close to the LNG carrier 80 in order to allow the initiation of the final steps, i.e. connection to the LNG manifold 90 using the dedicated connection system 91,90.
  • Figures 3e-f show the situation where both the first and second support arms 5, 8 are in a position transverse to the vertical support 1, that is where the free end of the second support arm 8 is furthest away from the FLNG 70, and in a proximity of the LNG manifold 90 considered sufficient for initiating the final steps.
  • FIGs 4a-4c illustrates how the second hose end 63a approaches the LNG manifold 90 in accordance with the invention (see also figure 3g ).
  • three separate transfer hoses 60 are shown, all connected to a common hose end guide means 102, here in the form of a connecting bar element 102.
  • each of the second hose ends 63a comprises a clamping device 98 and a distance member 94, the latter being fixed between the clamping device 98 and the hose end guide means 102.
  • the distance member 94 ensures a stable connection between the bar element 102 and the second hose ends 63a.
  • the clamping device 98 may be activated manually, by springs or by a hydraulic or pneumatic cylinder unit.
  • the LNG manifold 90 is provided with receiving means 71 in the form of an elongated cradle arranged in parallel with the bar element 102 and above the manifold connectors 15 and LNG manifold tubes 16.
  • the receiving means or cradle 71 is configured to receive the common hose end guide means or bar element 102, thereby causing the desired load release.
  • Figure 4d illustrates in more detail disconnection of the assisting line 150 from the LNG manifold 90 after a successful attachment of the guiding line 35.
  • the assisting line 150 is in this embodiment attached to the common hose end guide means 102 by one or more attachment lines 103.
  • the guiding line 35 and/or attachment lines 103 are guided through dedicated bar sheaves 152 situated on the hose end guide means or bar elements 102, and fixed to an attachment line stopper 104 connected to the assisting line 150.
  • the assisting line 150 is lowered until the stopper 104 is situated under a fork like protrusion 107 protruding from the LNG manifold 90 from a rod fixed between the LNG manifold tubes 16.
  • the stopper 104 abuts the inside of the fork, thereby establishing a connection between the attachment line 103 (or alternatively the guiding line 37 directly) and the fork like protrusion 107.
  • the subsequent raising of the assisting line 150 using dedicated winches removes the assisting line 150 completely from the attachment line 103.
  • the further lowering of the second hose ends 63a will, by pivoting around the bar element 102, align each second hose end 63a into a connection position with the manifold connector 15.
  • the hose end connector unit 91 is now ready to be locked in leak free fluid communication with the LNG manifold 90, see fig 4e .
  • the locking is carried out by engaging the clamping device 98 on the hose end coupler valve 14 to the corresponding manifold connector 15.
  • a procedure for emergency release of the second hose end 63a is also included and shown in Figures 5a-d .
  • the hose end coupler valve 14 connected to the hose end valve 13 is firstly closed in order to prevent further fluid flow from the hose end valve 13 into the hose end coupler valve 14.
  • the clamping device 98 in figure 5 may be activated by springs or hydraulic or pneumatic cylinder units 99.
  • the activation of the cylinder unit 99 may cause an increase in the diameter of the clamping device 98, which again causes a separation of the hose end connector valve 13 from the hose end coupler valve 14, the latter being left behind on the LNG manifold 90, see Figure 5b .
  • the second hose end 63a has transfer line(s) 27 connected on the hose end valve 13 and the transfer lines 27 are further connected via the support structure 100,5,8, sheaves 30,31,28,29,24 and counter weight 22 to the transfer line winch 23.
  • the weight at the counter weight attached to the transfer line(s) 27 will cause a rapid retrieval of the second hose end 63a from the LNG manifold 90 since the total counterweight set at least partly by the attached counter weight 22 is larger that the total weight experienced at the end of the transfer line(s) 27 closest to the LNG carrier 80, see figure 5c .
  • Figure 5d illustrates in a schematic view the transfer system after a successful emergency release.
  • FIG. 6a-e shows an alternative embodiment in accordance with the invention.
  • the above mentioned support structure 100 is illustrated as a column 1 arranged with a transverse single arm 110 (corresponding to the first and second support arm 5,8 in figures 2 and 3 ).
  • the arrangement or transfer system of this alternative embodiment comprises guiding line(s) 35 connected to the support structure 100 via second guiding line sheave 38 and third guiding line sheave 34.
  • the guiding line 35 is provided with lifting and lowering means such as a guiding line winch 33 for paying out and retrieving the guiding line 35 and thereby controlling the position of the second hose end 63a.
  • the arrangement also includes transfer line(s) 27 connected to the second hose end 63a on the hose end valve 13.
  • the transfer line 27 is connected to the support structure 100 via second transfer line sheave 31, third transfer line sheave 28 and counter weight sheave 24, and provided with lifting and lowering means such as a counter weight 22 and/or a transfer line winch 23 for paying out and retrieving the transfer line 27.
  • the second hose ends 63a include guide means 102 which may be a bar member arranged in an elevated position above the hose end coupler valve 14 by a distance member 94.
  • Receiving means 71 here shown as a cradle, is arranged elevated from LNG manifold 90 above the LNG manifold tube(s) 16 and is configured for receiving the bar member 102.
  • the hose end coupling unit 91 is hence allowed to be tilted downwards in direction of the receiving assembly 90 as illustrated in Figure 6b .
  • the assisting line 150 is subsequently connected to the LNG manifold 90, and as illustrated by the wave form of the guiding line 35 in Figure 6c , the connection is preferably performed such that the guiding line 35 has a certain slack to allow for movements of the LNG carrier 80. Any additional relative movements between the LNG carrier 80 and the FLNG 70 may be compensated by paying out and retrieving the guiding line 35 / assisting line 150 using the guiding line winch 33.
  • the transfer line winch 23 is then brought into operation and the transfer line 27 is paid out from the winch 23 as the weight lowers the second hose end 63a along the attached guiding line 35 towards the LNG manifold 90 and into a connecting position, thereby allowing a leak free fluid communicating connection with the LNG manifold 90.
  • the weight experienced at the end of the transfer line 27 due to the second hose end 63a with its connection unit 91 is larger than the total weight acting on the attachment point of the counter weight 22 on the transfer line 27, thus resulting in a vertical displacement of the counter weight 22 within the counter weight guiding cylinder 26 to an elevated end stop position, for example using dedicated counter weight end stops 25 ( Figures 6a-f ).
  • the guiding line 35 is to be attached to an attachment point provided at the LNG manifold 90.
  • the attachment point may be the fork like protrusion 107 mentioned earlier. However, it may be any kind of blocking means that can hold the hose end guiding line 35 and/or assisting line 150 in position.
  • the assisting or messenger line 150 (or the guiding line 35) directs the guide means or bar element 102 into the receiving means or cradle 71.
  • the load of the second hose end 63a is transferred to the receiving means 71.
  • the second hose end 63a is then ready to be connected in a leak free fluid communicating connection to the LNG manifold 90.
  • the transfer line(s) 27 retrieve(s) the second hose end 63a and the hose end valve 13 by use of the counter weight 22, and the guiding line(s) 35 compensate(s) for the relative movement occurring between the FLNG 70 and the LNG carrier 80.
  • Figure 8 shows another embodiment of the second hose end 63a which also shows part of the receiving LNG manifold 90 comprising the LNG manifold tube 16, the manifold connector 15 and the manifold receiving means 71.
  • the second hose portion 62, the bending restrictor 130, the hose end valve 13 and the hose end coupler valve 14 are seen connected in fluid communication with each other.
  • An appropriate clamping device 98 is mounted onto the hose end couple valve enabling leak free coupling with the LNG manifold tube 16.
