[0010] Hereinafter, the piping connection equipment and hose saddle according to the embodiments of this disclosure will be described with reference to Figures 1 to 7. (Configuration of the piping connection equipment) As shown in Figure 1, the piping connection equipment 10 of this embodiment includes a land-side fixed pipe 20 as a fixed pipe and a hose saddle 30. The piping connection equipment 10 is used when transferring liquefied gas between a liquefied gas storage facility 40 and a ship 1 through a hose 100. In this embodiment, one end 100a of the hose 100 is connectable to the liquefied gas storage facility 40, and the other end 100b is connectable to the ship 1. Examples of liquefied gas to be transferred include ammonia. In addition to ammonia, the liquefied gas may also be LNG (liquefied natural gas), LPG (liquefied petroleum gas), carbon dioxide, hydrogen, etc.

[0011] The vessel 1 comprises a hull 2 ​​and a tank (not shown). The hull 2 ​​has a pair of sides 3 that form its outer shell (only one side 3 is shown in Figure 1), a bottom (not shown), and an upper deck 5. The pair of sides 3 each have a pair of side platings that form the port and starboard sides, respectively. The bottom has bottom platings that connect these sides 3. A superstructure (not shown) containing living quarters is formed on the upper deck 5 of the hull 2.

[0012] A tank (not shown) is located within the hull 2. The tank may also be located on the upper deck 5. The tank is capable of storing liquefied gas inside. The tank may store liquefied gas as cargo, or it may store liquefied gas as fuel for a combustion device capable of burning fuel for, for example, a main engine, auxiliary engine, or generator engine (none of which are shown) housed within the hull 2.

[0013] A ship-side fixed piping 7 is connected to the tank. The ship-side fixed piping 7 is supported from below on the upper deck 5 via a support base 9. A flange 7f is provided at the tip of the ship-side fixed piping 7. The other end 100b of the hose 100 is provided with a ship-side connection port (not shown) and a flange 102. The other end 100b of the hose 100 is detachably connected to the tip of the ship-side fixed piping 7 by connecting the flange 102 and flange 7f with a number of bolts (not shown). Multiple sets of tanks (not shown) and ship-side fixed piping 7 may be provided.

[0014] The liquefied gas storage facility 40 is equipped with a land-side tank (not shown) capable of storing liquefied gas. The land-side tank is capable of storing the same type of liquefied gas as the tank (not shown) provided in the hull 2.

[0015] Figure 2 is a side view showing a piping connection facility and hose saddle according to an embodiment of the present disclosure. As shown in Figures 1 and 2, the land-side fixed piping (fixed piping) 20 in this embodiment is provided in the liquefied gas storage facility 40. In this embodiment, for example, three land-side fixed pipes 20 are provided. Each land-side fixed pipe 20 is connected to a land-side tank. The land-side fixed pipes 20 are supported from below on the quay wall 25 via a support frame 26. As shown in Figure 2, in this embodiment, the support frame 26 is provided on a trolley 27 that is movable on the quay wall 25. The support frame 26 may be fixed to the quay wall 25.

[0016] The land-side fixed piping 20 extends along an axis O that extends horizontally. A flange 22 is formed at the tip of the land-side fixed piping 20, which expands radially outward from the axis O. A connection port 24 is provided at the tip of the land-side fixed piping 20. The connection port 24 opens radially inward from the flange 22. The connection port 24 opens with the axis O that extends horizontally as its center. For example, the connection port 24 opens on one side Da1 in the axial direction Da along axis O, facing the sea side where the ship 1 docks.

[0017] The land-side fixed piping 20 has a fixed piping body 21 and an emergency detachment section 28. The fixed piping body 21 is a portion of the land-side fixed piping 20 on one end side (the side closer to the land-side tank) in the extension direction (axial direction Da) of the land-side fixed piping 20, relative to the emergency detachment section 28. The emergency detachment section 28 is a portion of the land-side fixed piping 20 on the other end side (the side opposite to the land-side tank) in the extension direction (axial direction Da) of the land-side fixed piping 20, relative to the fixed piping body 21, relative to the land-side fixed piping body 21.

[0018] An emergency release section 28 has a connection port 24. The other end Da2 of the emergency release section 28 in the axial direction Da is flange-connected to the fixed piping body 21. One end 100a of the hose 100 is detachably connected to the end Da1 of the emergency release section 28 in the axial direction Da. A flange 101 is provided on the one end 100a of the hose 100. By connecting the flange 101 and the flange 22 with a plurality of bolts (not shown), one end 100a of the hose 100 is detachably connected to the tip of the land-side fixed piping 20.

[0019] The emergency detachment section 28 is designed to detach from the fixed piping body 21 toward one side Da1 in the axial direction Da by a drive mechanism (not shown). The drive mechanism operates when predetermined conditions are met, such as when the pressure in the system through which the liquefied gas flows, including the land-side fixed piping 20 and hose 100, rises excessively, when a leak of liquefied gas occurs, or when excessive force is applied to the hose 100 in the direction of extension. The emergency detachment section 28 is instantly detached from the fixed piping body 21 by the operation of the drive mechanism. As a drive source for the drive mechanism, for example, nitrogen gas, a hydraulic cylinder, etc., can be used as appropriate.

[0020] In this embodiment, the same number of hose saddles 30 as the number of fixed pipes 20 are provided. In this embodiment, for example, three sets of hose saddles 30 are provided. Each hose saddle 30 comprises a saddle body 31 and a support base 32. The support base 32 is provided on the quay wall 25. The support base 32 has a plurality of support columns 32c spaced apart in the axial direction Da. The plurality of support columns 32c support the saddle body 31 from below. The support base 32 may be made movable on the quay wall 25 by providing wheels or the like.

[0021] Figure 3 is a perspective view showing the saddle portion of a hose saddle in an embodiment of the present disclosure. As shown in Figures 2 and 3, the saddle body 31 has a saddle portion 33 and a side guide portion 34 (see Figure 3). When viewed from above, the saddle portion 33 is formed as a strip extending in the axial direction Da. When viewed from above, the saddle portion 33 has a predetermined width in the width direction Dw of the saddle portion 33 that intersects the axial direction Da in the horizontal plane. The saddle portion 33 has an upward-facing saddle surface 33f. When viewed from the width direction Dw, the saddle portion 33 is curved in an S-shape. The saddle portion 33 has a first extending portion 36, a second extending portion 37, and a third extending portion 38. The first extending portion 36, the second extending portion 37, and the third extending portion 38 are provided in the order of first extending portion 36, second extending portion 37, and third extending portion 38, from the other side Da2 toward the one side Da1 in the axial direction Da.

[0022] As shown in Figure 2, one end of the first extension portion 36 is positioned below the connection port 24. The first extension portion 36 extends away from the connection port 24 in the axial direction Da. In this embodiment, the first extension portion 36 extends horizontally.

[0023] The second extension portion 37 extends upward from the first extension portion 36. In this embodiment, the second extension portion 37 extends diagonally upward as it moves away from the first extension portion 36 to one side Da1 in the axial direction Da. When viewed from the width direction Dw, the angle θ at which the second extension portion 37 is inclined with respect to the axial direction Da (horizontal direction) is preferably, for example, 30° ≤ θ ≤ 80°.

[0024] The saddle portion 33 has a curved surface 39 that extends from the first extending portion 36 to the second extending portion 37, and is curved so as to be convex downward when viewed from the width direction Dw. The curved surface 39 is formed at least at the boundary portion between the first extending portion 36 and the second extending portion 37. The curved surface 39 may extend over the entire length of the first extending portion 36 and the second extending portion 37. In this case, the first extending portion 36 and the second extending portion 37 are formed by the curved surface 39 that is curved in an arc shape when viewed from the width direction Dw.

[0025] The third extension portion 38 extends from the second extension portion 37 toward one side Da1. The third extension portion 38 curves downward as it moves away from the connection port 24. The third extension portion 38 is curved so as to be convex upward when viewed from the width direction Dw. When viewed from the width direction Dw, it is preferable that the top portion 38t of the third extension portion 38 is located above the first extension portion 36 with a height difference H of, for example, the diameter of the flange 22.

[0026] As shown in Figure 3, the side guides 34 are provided on both sides of the saddle portion 33 in the width direction Dw. Each of the pair of side guides 34 is provided above the saddle surface 33f via a plurality of support members 34s spaced apart in the extending direction of the saddle portion 33. Each side guide extends along the extending direction of the saddle portion 33. Each side guide can be formed from, for example, a round pipe or a round bar. When the emergency release portion 28 or one end 100a of the hose 100 is placed on the saddle portion 33, the flange 22 of the emergency release portion 28 and the flange 101 of the hose 100 come into contact with the side guides 34, preventing the emergency release portion 28 or one end 100a of the hose 100 from deviating from the saddle surface 33f in the width direction Dw.

[0027] (Method of connecting a hose using a pipe connection device) Figure 4 shows a state in which one end of the hose is positioned vertically above the second extension in the pipe connection device according to an embodiment of the present disclosure. Figure 5 shows a state in which one end of the hose is inclined to follow the second extension in the pipe connection device according to an embodiment of the present disclosure. Figure 6 shows a state in which one end of the hose is connected to a fixed pipe along the first extension in the pipe connection device according to an embodiment of the present disclosure. To connect the hose 100 using the pipe connection device 10 as described above, first, as shown in Figure 1, the hose 100 is lifted by a crane 90 provided on the ship 1 side, for example. Here, the crane 90 may be one provided on the quay 25. When the hose 100 is lifted, the hose 100 will be in a state where one end 100a is pointing vertically downward. Next, as shown in Figure 4, one end 100a of the hose 100 lifted by the crane 90 is positioned vertically above the second extension 37 of the hose saddle 30.

[0028] From the state shown in Figure 4, the suspended hose 100 is lowered by the crane 90. When one end 100a of the hose 100 rests on the saddle surface 33f on the second extension 37, as shown in Figure 5, the one end 100a of the hose 100 changes direction as it descends following the inclined second extension 37 due to its own weight, and gradually tilts so that the one end 100a faces the other side Da2 in the axial direction Da. As shown in Figure 6, when the one end 100a of the hose 100 slides down from the second extension 37 to the first extension 36, the one end 100a of the hose 100 extends in the axial direction Da on the first extension 36, and the flange 101 faces the flange 22 of the fixed pipe 20 in the axial direction Da.

[0029] Subsequently, the worker connects the flange 101 of one end 100a of the hose 100 to the flange 22 of the fixed pipe 20 using several bolts (not shown), thereby connecting one end 100a of the hose 100 to the connection port 24 of the fixed pipe 20.

[0030] Meanwhile, on the upper deck 5, a worker connects the flange 102 of the other end 100b of the hose 100 to the flange 7f of the ship's fixed piping 7 with several bolts (not shown). This connects the other end 100b of the hose 100 to the ship's fixed piping 7. The order of connecting one end 100a of the hose 100 to the fixed piping 20 and the other end 100b of the hose 100 to the ship's fixed piping 7 is not limited in any way.

[0031] Figure 7 shows a pipe connection device in an embodiment of the present disclosure, in which the middle portion of the hose is aligned with the third extended portion. When the hose 100 is connected to the fixed pipe 20 and the ship-side fixed pipe 7 in this manner, the middle portion of the hose 100 is stretched between the ship 1 and the quay 25. As shown in Figure 7, if the middle portion 100c of the hose 100 hangs down below the third extended portion 38 of the hose saddle 30 due to the weight of the hose 100, the hose 100 will curve to follow the curved third extended portion 38, which is curved to be convex upward. This prevents localized force from being applied to the hose 100 due to contact with the hose saddle 30.

[0032] Furthermore, with one end 100a of the hose 100 connected to the fixed piping 20, if the emergency release section 28 detaches from the fixed piping body 21 to one side Da1 in the axial direction Da, the emergency release section 28 collides with the second extending section 37, which extends diagonally upward. This consumes the energy that the emergency release section 28 would have used to move to one side Da1 in the axial direction Da, thus preventing the emergency release section 28 from scattering to one side Da1 in the axial direction Da.

[0033] (Effects) The piping connection equipment 10 and hose saddle 30 of the above embodiment have a first extending portion 36, one end of which is positioned below the connection port 24 and which extends away from the connection port 24 in the axial direction Da. As a result, when attaching or detaching one end 100a of the hose 100 to the connection port 24, the first extending portion 36 supports one end 100a of the hose 100 from below and guides one end 100a of the hose 100 in the direction of moving toward and away from the connection port 24. In addition, a second extending portion 37 extends upward from the first extending portion 36. When attaching or detaching one end 100a of the hose 100 to the connection port 24, the hose 100 on the side of the other end 100b is positioned along the second extending portion 37 that extends upward from the one end 100a. Therefore, it is possible to suppress displacement of one end 100a of the hose 100 away from the connection port 24. As a result, the attachment and detachment of the hose 100 can be made easier, reducing the burden on the workers.

[0034] Furthermore, in the above embodiment, the second extending portion 37 extends diagonally upward as it moves away from the first extending portion 36. As a result, when the hose 100 is suspended from above and one end 100a of the hose 100 is connected to the connection port 24, when the downward-facing end 100a of the hose 100 comes into contact with the second extending portion 37, the end 100a of the hose 100 changes direction toward the connection port 24, following the second extending portion 37. This allows the end 100a of the hose 100 to be smoothly connected to the connection port 24. In addition, it is not necessary for multiple workers to hold the end 100a of the hose 100 in order to change its direction. Therefore, the attachment and detachment of the hose 100 can be made even easier, and the burden on workers can be reduced.

[0035] Furthermore, in the above embodiment, a curved surface 39 is formed extending from the first extended portion 36 to the second extended portion 37. This allows the downward-facing end 100a of the hose 100 to be smoothly turned towards the connection port 24 when the hose 100 is suspended from above and one end 100a of the hose 100 is connected to the connection port 24.

[0036] Furthermore, the above embodiment includes a pair of side guide portions 34. This prevents the hose 100 from shifting position in the width direction Dw on the saddle portion 33 and falling off the saddle surface 33f.

[0037] Furthermore, in the above embodiment, the saddle portion 33 further includes a third extending portion 38. This allows the middle portion 100c of the hose 100 to be supported from below by the third extending portion 38 when one end 100a of the hose 100 is connected to the connection port 24 and the hose 100 extends in a direction away from the connection port 24. When the hose 100 on the side away from the connection port 24 hangs downward, the third extending portion 38, which curves downward as it moves away from the connection port 24, can stably support the hose 100 while suppressing localized forces on the hose 100.

[0038] Furthermore, in the above embodiment, when the emergency release portion 28 is released, it can be received by the second extended portion 37. This prevents the emergency release portion 28 from colliding with other surrounding objects.

[0039] (Other Embodiments) Although embodiments of the present disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments and includes design changes and the like that do not depart from the gist of the present disclosure. In the above embodiments, the hose saddle 30 is provided on the land-side liquefied gas storage facility 40 side, but it is not limited to this. The hose saddle 30 may also be provided on the ship 1 side. In this case, the ship-side fixed piping 7 is made into fixed piping. The hose saddle 30 may also be provided on both the ship 1 and the land-side liquefied gas storage facility 40. Furthermore, the emergency release section 28 may be provided on either the liquefied gas storage facility 40 or the ship 1.

[0040] <Note> The piping connection equipment 10 and hose saddle 30 described in the embodiment can be understood, for example, as follows.

[0041] (1) The piping connection equipment 10 according to the first embodiment comprises a fixed pipe 20 having a connection port 24 that opens around an axis O extending in the horizontal direction, and a hose saddle 30 having a saddle portion 33 that can support one end 100a of a hose 100 that is detachably connected to the connection port 24 from below, wherein the saddle portion 33 has one end positioned below the connection port 24 and a first extending portion 36 that extends away from the connection port 24 in the axial direction Da of the axis O, and a second extending portion 37 that extends upward from the first extending portion 36.

[0042] This piping connection device 10 has a first extending portion 36, one end of which is positioned below the connection port 24 and which extends away from the connection port 24 in the axial direction Da. As a result, when attaching or detaching one end 100a of the hose 100 to the connection port 24, the first extending portion 36 supports the one end 100a of the hose 100 from below and guides the one end 100a of the hose 100 in the direction of moving toward and away from the connection port 24. A second extending portion 37 extends upward from the first extending portion 36. When attaching or detaching one end 100a of the hose 100 to the connection port 24, the hose 100 on the side of the other end 100b is positioned along the upward-extending second extending portion 37. Therefore, displacement of one end 100a of the hose 100 away from the connection port 24 can be suppressed. As a result, the attachment and detachment of the hose 100 can be made easier, reducing the burden on the workers.

[0043] (2) The piping connection equipment 10 according to the second embodiment is the piping connection equipment 10 of (1), wherein the second extending portion 37 extends diagonally upward as it moves away from the first extending portion 36.

[0044] According to such a configuration, the second extending portion 37 extends obliquely upward as it moves away from the first extending portion 36. Thus, when the hose 100 is suspended from above and one end portion 100a of the hose 100 is connected to the connection port 24, if one end portion 100a of the downward-facing hose 100 contacts the second extending portion 37, the orientation of one end portion 100a of the hose 100 changes toward the connection port 24. Thereby, one end portion 100a of the hose 100 can be smoothly connected to the connection port 24. Also, in order to change the orientation of one end portion 100a of the hose 100, it is not necessary for a plurality of workers to hold one end portion 100a of the hose 100. Therefore, the attachment / detachment operation of the hose 100 can be further facilitated, and the burden on the worker can be reduced.

[0045] (3) The pipe connection facility 10 according to the third aspect is the pipe connection facility 10 of (1) or (2), wherein the saddle portion 33 has a curved surface 39 that curves downward so as to be convex from the first extending portion 36 to the second extending portion 37.

[0046] Thus, when the hose 100 is suspended from above and one end portion 100a of the hose 100 is connected to the connection port 24, the orientation of one end portion 100a of the downward-facing hose 100 can be smoothly changed toward the connection port 24.

[0047] (4) The pipe connection facility 10 according to the fourth aspect is any one of the pipe connection facilities 10 of (1) to (3), wherein the hose saddle 30 further includes a pair of side guide portions 34 provided above the saddle portion 33 and extending along the extending direction of the saddle portion 33 on both sides in the width direction Dw of the saddle portion 33 that intersects the extending direction of the saddle portion 33.

[0048] Thereby, on the saddle portion 33, it is possible to prevent the hose 100 from being displaced in the width direction Dw of the saddle portion 33 and falling off from the saddle portion 33.

[0049] (5) The piping connection equipment 10 according to the fifth embodiment is any one of the piping connection equipment 10 of (1) to (4), wherein the saddle portion 33 further comprises a third extending portion 38 which is connected to the upper end of the second extending portion 37 and extends in a curve downward as it moves away from the connection port 24.

[0050] As a result, when one end 100a of the hose 100 is connected to the connection port 24, and the hose 100 extends away from the connection port 24, the hose 100 can be supported from below by the third extending portion 38. When the hose 100 hangs downward on the side away from the connection port 24 relative to the third extending portion 38, the third extending portion 38, which curves downward as it moves away from the connection port 24, can stably support the hose 100 while suppressing localized forces on the hose 100.

[0051] (6) The piping connection equipment 10 according to the sixth embodiment is any one of the piping connection equipment 10 from (1) to (5), wherein the fixed pipe 20 is provided with an emergency detachment section 28 that can be detached on the connection port 24 side of the fixed pipe 20.

[0052] As a result, if the fixed piping 20 is equipped with an emergency release section 28, the detached emergency release section 28 can be received by the second extended section 37. This prevents the detached emergency release section 28 from colliding with other surrounding objects.

[0053] (7) The hose saddle 30 according to the seventh embodiment is a hose saddle 30 capable of supporting one end 100a of a hose 100 that is detachably connected to a fixed pipe 20 having a connection port 24 that opens around an axis O extending in the horizontal direction, and comprises a saddle portion 33 capable of supporting one end 100a of the hose 100 from below, the saddle portion 33 having a first extending portion 36 with one end positioned below the connection port 24 and extending away from the connection port 24 in the axial direction Da along the axis O, and a second extending portion 37 extending upward from the first extending portion 36.

[0054] As a result, when attaching or detaching one end 100a of the hose 100 to the connection port 24, the first extending portion 36 supports the one end 100a of the hose 100 from below and guides the one end 100a of the hose 100 in the direction of moving toward or toward the connection port 24. Furthermore, the second extending portion 37 extends upward from the first extending portion 36. Therefore, when attaching or detaching one end 100a of the hose 100 to the connection port 24, the hose 100 on the other end 100b side of the one end 100a is positioned along the upward-extending second extending portion 37. Consequently, displacement of one end 100a of the hose 100 toward the connection port 24 can be suppressed. As a result, the attachment and detachment of the hose 100 can be made easier, and the burden on the worker can be reduced.

[0055] The piping connection equipment and hose saddle of this disclosure make it easy to attach and detach hoses, reducing the burden on workers.
