WO2014083056 discloses a solution for connecting a mooring line from a floating structure, such as a ship, to a structure situated on the seabed, typically an anchor installed in the seabed. A guideline extends from the ship down to a wire tackle attached to the anchor, and back up to the ship. One end of the guideline is connected to a winch on the ship for pulling in the guideline, while the other end connects to a mooring line. The mooring line is paid out while the guideline is pulled in. At the intersection between the guideline and the mooring line, there is an upper connection element that is configured to connect with a lower connection element attached to the anchor. When the upper connection element has been pulled into engagement with the lower connection element, they are attached to each other, thereby connecting the mooring line to the subsea anchor. With this solution, the operator is enabled to connect to a remote, not visible connection point at the subsea location without the use of an ROV (remotely operated vehicle) or a diver. Once the mooring line has been connected to the anchor, the operation is completed. -

US20140034137 presents an offshore fluid transfer system on a ship, and thus relates to the same field as the present invention. In this solution, a pulling line and an overhanging crane beam are used to move the end of an articulated fluid pipe into engagement with the fluid interface of an adjacent ship. The articulated fluid pipe absorbs mutual movement between the two ships. Notably, except for the two ships themselves, no part of the fluid transfer system is in contact with the seawater. - An object of the present invention may be to present equipment and a method that may reduce the risk for personnel injuries and/or to increase the operational limits.
- According to a first aspect of the present invention, there is provided a loading hose connection assembly having a pull-in line, a floating part, and a connecting part. The floating part comprises a buoyant body configured to make the floating part float in a body of water, a connecting part reception interface, a first locking element, a pull-in line guide element, and a loading hose connection interface. The connecting part comprises a second locking element configured to enter into locking engagement with the first locking element, a pull-in line connection interface, a crane string connection interface. According to the invention, the pull-in line extends from the pull-in line connection interface to the pull-in line guide element, and further to a pull-in section of the pull-in line, such that a pull in the pull-in section pulls the connecting part into the connecting part reception interface, thereby enabling a locking engagement with the floating part.
- It will be understood that the pull-in section of the pull-in line, which is pulled, is a portion of the pull-in line, which is outside the floating part and the connecting part. Typically, the pull-in section can be on a tanker or another ship.
- In some embodiments, the connecting part reception interface can be arranged in a receiving body with an entrance aperture, wherein the first locking means is arranged between the entrance aperture and the pull-in line guide element.
- Advantageously, the first locking element and the second locking element can in some embodiments be configured to automatically enter into a locking engagement when the connecting part is pulled into the connecting part reception interface. This means that no other actuation of the locking elements will be necessary in order to establish the locked connection between the floating part and the connecting part. In other words, the connecting part is pulled into the locking engagement by means of the pull-in line.
- Advantageously, in some embodiments the floating part may further comprise a pull-in line return channel. In such embodiments, the pull-in line may enter the floating part through an entrance aperture, and exit the floating part through the pull-in line return channel.
- In such embodiments, the connecting part reception interface and the pull-in line return channel may both have a straight, elongated extension, wherein the mutual angle between their respective axially extending center axes may be less than 30 degrees.
- In some examples of such embodiments, the pull-in line return channel may have a return channel aperture and the floating part may further comprise an auxiliary return aperture, which is configured to guide the pull-in line out of the floating part.
- In such embodiments, the pull-in line may be returned out from the assembly without extending through the pull-in line return channel. As will be shown with the more detailed discussion further below, the use of the auxiliary return aperture will typically be used when the pull-in of the connecting part is performed from a tug. In such situations, there may be a significant angle between the portion of the pull-in line extending into the assembly and the portion that returns out from the assembly.
- According to a second aspect of the present invention, there is provided a method of providing, by using the loading hose connection assembly according to the first aspect of the invention, a connection between a crane hook of a ship crane and a floating loading hose floating in the sea, and lifting the loading hose onto a ship.

- b) connecting an end of a pull-in line of the connection assembly to the connecting part;
- c) pulling in the opposite end or in a pull-in section of the pull-in line and paying out crane wire from the crane, thereby pulling the connecting part towards a floating part of the connection assembly, which is connected to the floating loading hose, as the pull-in line runs freely into and out of the floating part;
- d) locking the connecting part to the floating part by pulling the pull-in line, as the connecting part and the floating part comprises locking elements configured to automatically establish a locked connection when the connecting part is pulled into a connecting part reception interface;
- e) lifting the loading hose onto the ship by transmission of lifting force from the crane hook to the loading hose, as the locked connection between the floating part and the connecting part is configured to transmit said lifting force.
- In some embodiments of the method according to the second aspect of the invention, step c) may comprise pulling the pull-in section from a position on the same ship as on which the ship crane is mounted. That is, in such embodiments, the part of the pull-in line that extends out from the connection assembly and which is pulled, is pulled from a position on a ship, on which the crane is positioned. Such a ship may typically be a tanker, onto which fluid shall be loaded through the loading hose.
- Moreover, step c) may alternatively comprise pulling the pull-in section from a position on another ship than the ship on which the ship crane is mounted. Such an embodiment will be discussed in one the examples below.
- By automatically establishing a locked connection between the floating part and the connecting part of the connection assembly, it is herein meant that the actuation of the locking function may take place by operation of the pull-in line. I.e. by a pull in the pull-in line, so that the two parts are mated together into a locked position.

Fig. 1 shows a typical situation before a floating loading hose 1 is connected to atanker 3. Thetanker 3 is positioned adjacent the floating loading hose 1, which floats in the sea and which is connected to a fluid reservoir, such as a floating buoy (not shown). Thetanker 3 is provided with acrane 5. Thecrane 5 has acrane hook 7 at the end of acrane wire 9. - The end of the loading hose 1 is provided with a
coupling 11 configured for connection to a connection flange (not shown) on thetanker 3. Also arranged on the end of the loading hose 1 is a liftingchain 13, which is used to lift the end of the loading hose. - Adjacent the tanker 1 and the floating
hose 3 is atug 15. In the situation shown inFig. 1 , personnel on thetug 15 control the end of the loading hose 1 with a towingline 17 connected to the liftingchain 13. As discussed above, with operations according to the prior art, the personnel on thetug 15 will manually connect the liftingchain 13 to thecrane hook 7. Since the floating hose will move and thetug 15 may roll and heave due to waves, this operation may be hazardous and cannot be performed during excessive wave heights. -
Fig. 2 and Fig. 3 show aconnection assembly 10 according to the present invention, the use of which makes it possible to reduce hazard during the connection of thecrane hook 7 to the floating hose 1. - The
connection assembly 10 comprises a floatingpart 50, a connectingpart 70, and a pull-inline 20. The connectingpart 70 is configured to be locked to the floatingpart 50 when pulled towards the floating part by means of the pull-inline 20. The pull-inline 20 can typically be a rope or any other suitable string. -
Fig. 2 depicts the assembly in a non-connected state. The floating part has abuoyant body 51, which has such a weight and volume that it makes theassembly 10 float in a body of water. Thebuoyant body 51 can advantageously comprise a hardening foam, giving both low weight and robustness. The floatingpart 50 will float in water when the connectingpart 70 is not connected to the floatingpart 50. However, the floatingpart 50 may advantageously also be made to float in water when the connectingpart 70 is connected. -
Fig. 2 and Fig. 3 depict theconnection assembly 10 with cross section side views. In the shown embodiment, thebuoyant body 51 has a circular shape with a centrally arrangedopening 53. Thebuoyant body 51 is attached to the upper portion of asleeve 55, which extends through theopening 53. - The lower end of the
sleeve 55 comprises a loading hose connection interface, here shown in the form of achain connection 57. The loadinghose connection interface 57 is configured to be connected to the floating loading hose 1 (Fig. 1 ) for hoisting the end of the hose onto thetanker 3. - The upper end of the
sleeve 55 comprises aguide funnel 59. The guide funnel is arranged at the upper end of a connectingpart reception interface 61, which in the shown embodiment is inside thesleeve 55. In this embodiment, theguide funnel 59 constitutes anentrance aperture 52 of the connectingpart reception interface 61. - In a wall portion of the
sleeve 55 and positioned at a lower section of the sleeve, there is a pull-inline guide element 63. In this embodiment, the pull-in line guide element is in form of asheave 63 on which the pull-inline 20 is guided. As can be seen with the cross section view ofFig. 2 , the pull-inline 20 enters thesleeve 55 at an upper portion of the sleeve, through theguide funnel 59. The pull-inline 20 extends downward to the pull-inline guide element 63, at which position it exits thesleeve 55 through anaperture 65 in the sleeve wall. The pull-inline 20 then extends back upwards along thesleeve 55, on the external part of the sleeve, and through a pull-inline return channel 67. - The pull-in
line 20 is at one end attached to the connectingpart 70, via a pull-inline connection interface 71 at a lower end of the connecting part. When pulling in the part of the pull-inline 20 that extends out of the floatingpart 50, and which is opposite the end of the pull-in line connected to the connectingpart 70, the connectingpart 70 will be pulled towards the floatingpart 50. Such a pull is indicated with thearrow 20b, and this part of the pull-inline 20 is termed a pull-insection 20a. Eventually, the connectingpart 70 will be pulled into engagement with the floatingpart 50, as is shown withFig. 3 . In this position, the connectingpart 70 has been pulled into the connectingpart reception interface 61, namely inside thesleeve 55. When being pulled into this position, the connectingpart 70 is guided by means of theguide funnel 59. - In the embodiment shown in
Fig. 2 and Fig. 3 , the connectingpart 70 has acentral stem 73. The pull-inline connection interface 71 is arranged at a lower portion of thecentral stem 73. At an upper portion, the connectingpart 70 is provided with a cranestring connection interface 75. The crane string connection interface is attached to a crane wire 9 (cf.Fig. 1 ). - The connecting
part 70 further comprises a second locking element, which in the shown embodiment is in form of a radiallycompressible locking sleeve 77. The lockingsleeve 77 may comprise axially extending slits at its upper portion, which make the upper portion of the sleeve radially compressible. When pulled into thesleeve 55 of the floatingpart 50, thesecond locking element 77 is configured to make a locking engagement with afirst locking element 69. In the shown embodiment, the first locking element is in the form of an axially facing locking shoulder inside the bore of thesleeve 55. Thus, when pulled into thesleeve 55, the axially and upwardly facing edges 77a of thesecond locking element 77 are moved past the axially and downwardly facing lockingshoulder 69 of the floatingpart 50. - The
sleeve 55 forms a receiving body, configured to receive at least a portion of the connectingpart 70, wherein the said portion is pulled beyond theentrance aperture 52. - When the connecting
part 70 has been locked to the floatingpart 50, the crane 5 (Fig. 1 ) may hoist theconnection assembly 10 and the end of the floating loading hose 1 onto the tanker, as the floatingpart 50 is attached to the loading hose. This attachment may be provided with a connection between the floatingpart 50 and the lifting chain 13 (Fig. 1 ). - Thus, in order to connect the
crane hook 7 to thecoupling 11 at the end of theloading hose 7, the operator employs a pull-inline 20 that extends to the connectingpart 70, via the floatingpart 50. The floatingpart 50 is attached to the end of theloading hose 7, such as with the lifting chain 13 (Fig. 1 ). The pull in the pull-inline 20 and the paying out of thecrane wire 9, will move the connectingpart 70 into a locked engagement with the floatingpart 50. Since the connectingpart 70 is attached to thecrane hook 7, the operator may lift the loading hose end once the locking engagement between the connectingpart 70 and the floatingpart 50 has been made. - Notably, this operation may be performed without any personnel being close to the
crane hook 7 or the end of the loading hose 1 (e.g. the coupling 11), when the connection is made between the crane and the loading hose 1. Consequently, the operator has reduced risk for injuries and the operation is less limited by wave heights. - Advantageously, between loading operations, i.e. when the
connection assembly 10 according to the invention is not in use, it should be stored in a dry state in order to prevent fouling. If for instance being used in a situation involving a CALM (catenary anchor leg mooring) buoy, the loading hose will typically be floating at sea all the time. In such a situation, one may advantageously store theconnection assembly 10 on board a workboat between the operations. - If for instance being used in a situation involving a CTV (cargo transfer vessel), the
connection assembly 10 may be connected to the floating hose end before the floating hose is reeled out from the storage reel. When the loading operation is finished, the loading hose is reeled back onto the reel on the ship, and theconnection assembly 10 will be disconnected. -
Fig. 4 schematically depicts a situation where the operator is in the process of pulling the connectingpart 70 towards the floatingpart 50. A person on thetug 15 controls the pulling of the pull-inline 20 by using a winch 19 on the tug, which provides the pulling force in the pull-in line. Also connected to the liftingchain 13 and/or the floatingpart 50 is the towingline 17. -
Fig. 5 schematically depicts a situation similar to that inFig. 4 , however where the operator pulls the pull-inline 20 from a position on thetanker 3. -
Fig. 6a to Fig. 6e illustrate the process of connecting thecrane hook 7 to the floating hose 1, via theconnection assembly 10 according to the invention. As with the situation discussed above with reference toFig. 4 , the personnel handling the pull-inline 20 is on thetug 15. - In
Fig. 6a , the connectingpart 70 has been connected to thecrane hook 7. One end of the pull-inline 20 has been hoisted to personnel on thetanker 3. The personnel connects that end to the pull-inline connection interface 71 of the connectingpart 70, cf.Fig. 6b . - In the situation shown in
Fig. 6c , the operator pays out thecrane wire 9, while simultaneously pulling in the pull-inline 20 from the tug (not shown), making the connectingpart 70 approach the floatingpart 50. InFig. 6d , the connectingpart 70 has been pulled into locking engagement with the floatingpart 50, thus providing a robust connection between thecrane hook 7 and the end of the floating hose 1, via the liftingchain 13. - In the situation shown in
Fig. 6e , the operator lifts up the loading hose 1 by means of thecrane 5. -
Fig. 7a to Fig. 7e correspond toFig. 6a to Fig. 6e discussed above, except that the operator pulls the pull-inline 20 from a position on thetanker 3 and not from a position on thetug 15. -
Fig. 8 depicts a cross section view through a floatingpart 50 having a slightly different design compared to the one shown inFig. 2 and Fig. 3 . In the embodiment shown inFig. 8 , thebuoyant body 51 extends along more than half of the axial extension of thesleeve 55. Furthermore, the lower part of thebuoyant body 51 is positioned at the axial position of the pull-inline guide element 63. - In the situation shown in
Fig. 8 , the pull-inline 20 does not extend through the pull-inline return channel 67. Instead, it extends laterally out to the side of the floatingpart 50. This situation will typically be the case when the operator pulls the pull-inline 20 from thetug 15, as illustrated inFig. 4 . In such cases, the parts of the pull-inline 20 extending into and out from the floatingpart 50 will have substantially different directions. The floatingpart 50 has acutout 62 in thebuoyant body 51 to give space for the pull-inline 20 in such situations. - Referring now to
Fig. 9 , which depicts the same floatingpart 50 asFig. 8 . The pull-inline return channel 67 is arranged in thebuoyant body 51, and extends substantially or almost in parallel with thesleeve 55. Notably, between the position of theentrance aperture 52 and the position of the pull-inline guide element 63, the pull-inline 20 extends down and back up in a substantially parallel or almost parallel fashion. - The pull-in
line return channel 67 has areturn channel aperture 68, out of which the pull-inline 20 extends (i.e. out of which the pull-insection 20a of the pull-inline 20 extends). In the embodiment shown inFig. 9 , thereturn channel aperture 68 faces substantially in the same direction as theentrance aperture 52 of the connectingpart reception interface 61. - In the embodiment shown in
Fig. 9 , both the connectingpart reception interface 61 and the pull-inline return channel 67 have a straight, elongated extension. The mutual angle between their respective center axes may typically be less than 30 degrees, and advantageously less than 20 degrees. This may also apply to other embodiments within the scope of the invention. - Notably, letting the buoyant body extend downwards on the
sleeve 55, to the position of the pull-inline guide element 63, and arranging thecutout 62 in this position, provides some protection for the pull-inline guide element 63 against impacts. - While the pull-in
line guide element 63 shown in the embodiment discussed herein is in the form of a sheave, other embodiments may involve another type of pull-in line guide element. For instance, the pull-inline guide element 63 may merely comprise a curved, smooth edge, about which the pull-inline 20 may curve. -
Fig. 10 and Fig. 11 depict an alternative embodiment of theconnection assembly 10 according to the invention, in a non-connected and connected state, respectively. In this embodiment, the locking engagement between the floatingpart 50 and the connectingpart 70 is provided with means different from the embodiment discussed with reference toFig. 2 and Fig. 3 . - As with the previously discussed embodiment, the connecting
part 70 has acentral stem 73 configured to be pulled into asleeve 55 of the floatingpart 50. On thecentral stem 73, thesecond locking engagement 77 is arranged. In this embodiment, thesecond locking engagement 77 is in the form of a connection system commercially marketed under the name Ballgrab from the company First Subsea Ltd. Thecentral stem 73 is provided with a plurality of aperture in outer face, out of which apertures a plurality of balls partly extend. When thecentral stem 73 has been pulled into the connectingpart reception interface 61, inside thesleeve 55, the Ballgrab system forces the balls radially outwards and into engagement with the inner wall of the sleeve. This provides a locking engagement between the floatingpart 50 and the connectingpart 70. Such a connected state is shown inFig. 11 . In this embodiment, thefirst locking element 69 of the floatingpart 50 may be the radially inwardly facing wall of thesleeve 55, against which theballs 77 of the connectingpart 70 are forced when in the connected state. -
Fig. 12 and Fig. 13 depict yet another alternative embodiment of theconnection assembly 10 according to the invention. In this embodiment, thesecond locking element 77 is in form of three sliding elements. The slidingelements 77 are configured to slide in an axial direction on thecentral stem 73. Furthermore, thecentral stem 73 is provided with a tapered outer face, which will force the slidingelements 77 radially outwards when being pulled with thecrane wire 9. -
Fig. 12 shows theconnection assembly 10 in a non-connected state. InFig. 13 , thecentral stem 73 and the slidingelements 77 have been pulled into the connectingpart reception interface 61, i.e. within thesleeve 55. When a pulling force is exerted onto thecentral stem 73 from the cranestring connection interface 75, the tapered design of thecentral stem 73 will force the slidingelements 77 to expand radially. This radial expansion will provide mechanical engagement between the connectingpart 70 and the floatingpart 50, making the operator able to hoist the end of the loading hose 1 onto thetanker 3. -
Fig. 14a, Fig. 14b, and Fig. 14c illustrate the connectingpart 70 of the embodiment shown inFig. 12 and Fig. 13 with three cross sections views along three different portions of the connectingpart 70.Fig. 14a is a cross section view along a horizontal plane at a bottom part of thestem 73.Fig. 14b is a corresponding view at a mid-portion, whileFig. 14c is a cross section view along an upper portion. Each of the three slidingelements 77 is provided with a protrusion 77b that is received in a groove 73b in thecentral stem 73. The protrusion 77b and the groove 73b retains the slidingelements 77 in place on an outer inclined face 73c of thecentral stem 73. An inner face 77c of the sliding elements abuts the inclined face 73c. - Hence, by pulling the
central stem 73 upwards, the slidingelements 77 will be forced radially outwards when sliding against the outer inclined faces 73 of thecentral stem 73. This radially outward movement / force, will secure the connectingpart 70 to the floatingpart 50. - Notably, each of the three drawings of
Fig. 14a, Fig. 14b, and Fig. 14c are depicting the same situation, wherein the outer faces of the three slidingelements 77 have the same radial position. As thecentral stem 73 is pulled upwards, the diameter constituted by the outer faces of the three slidingelements 77 will increase.
