Pilot buoy 24 equipped with
It is configured by attaching 0.

As shown in Figures 1 and 2, the single point mooring buoy F for marine fluid cargo handling using the port line E for marine fluid cargo handling described above is constructed using a fluid transport hose Fa installed on the seabed and communicating with a base on land. This base Fb is connected to the base Fb.

- The fluid to be transported, such as crude oil, can be unloaded to the land base via the fluid transport hose Fa.

Next, to explain in more detail the marine fluid cargo handling hose line E mentioned above, in this embodiment, as shown in FIGS.
(2) The free end side 20a, that is, at the tip of the section P from the sea surface to the fluid loading port of the fluid transport vessel during cargo handling, An on-off valve 21 connectable to a fluid loading port (not shown) of the fluid transport vessel is installed, and a lead wire 23 is installed.
The pilot buoy 240 is attached to the fluid cargo handling hose (5) through which the base side 20b is attached to the rotary joint Fc of the marine fluid cargo handling single point mooring buoy F via the on-off valve 22; It is constructed by attaching the buoyancy adjustment hose 10 along the required floating/sinking section M of the fluid hose 20 for various purposes.

In this embodiment, as shown in FIG. 5, the pilot buoy 240 is divided into upper and lower parts to form the buoyancy chamber 244 in the upper part and the buoyancy adjustment chamber 241 in the lower part. 241, and an air supply/exhaust pipe 242 and a water pipe 243 are attached.

Therefore, when air is pressurized into the buoyancy adjustment chamber 241 from the supply/exhaust pipe 242 of the pilot buoy 240, the buoyancy adjustment chamber 241 is filled with the injected air.
Water is pushed out of the water pipe 243 and given buoyancy,
(See Figure 6 (al)) The free end side 20a of the fluid cargo handling port 20, that is, the section P from the sea surface to the fluid loading port of the fluid transport vessel during cargo handling, is shown in sequence from the tip side as shown in Figure 3 (al). When the trachea 242 is opened, the water pressure of the seawater that enters the buoyancy adjustment chamber 241 through the water pipe 243 causes the buoyancy adjustment chamber 2
The air filled in the tube 41 is pushed out from the supply/exhaust pipe 242 and loses its buoyancy (see Fig. 6 (bl)). As shown in FIG. 3(b), the section P leading to the fluid loading port can be sequentially brought to the bottom from the sinking side.

In the figure, 245 is an on-off valve provided on the supply/exhaust pipe 242, and 246 is an on-off valve provided on the water pipe 243, which the diver directly operates during the floating and sinking operation of the pilot buoy 240 mentioned above. or
It may be configured so that floating and sinking operations can be performed by remote control.

In the present embodiment, the buoyancy adjustment port 10 has a diameter that remains the same regardless of whether air is pressurized into the interior through the air supply/exhaust valve 11 and buoyancy is applied, or when the air is removed and seawater enters the interior. A hose constructed such that it hardly changes is used (7). In this embodiment, an on-off valve 12 is provided on the sinking side 10b that allows water to pass through. however,
Of course, this on-off valve 12 is not necessarily required and may be kept open all the time.

Further, as shown in FIG. 1, a pilot buoy 14 of the buoyancy adjustment hose 10 is attached to the air supply/exhaust valve 11 provided on the floating side 10a of the buoyancy adjustment hose 10 via a lead wire 13. This allows the user to easily check the sinking position of the supply/exhaust valve 11 when the port line E for fluid loading and unloading on the main island is sinking.

Of course, this pilot buoy 14 is provided with a supply/exhaust valve, and the lead wire 13 is provided with an air supply hose.
Air may be forced into the buoyancy adjustment hose 10 through these to make it float.

In addition, in this embodiment, the fluid cargo handling hose 20 is connected along the buoyancy adjustment hose 10 described above as a set of two (8) via a connector 30, as shown in FIGS. 7 to 10. installed.

Furthermore, when the above-mentioned fluid cargo handling hose 20 is forced to feed air into the buoyancy adjustment hose 10 to float the two-fluid cargo handling hose line E to the main island, there is a section under the sea as shown in FIG. N, that is, the floating bodies 40 are placed at intervals in the section N from the part floating in the sea to the rotary joint Pc.
is attached to it, so that when the marine fluid cargo handling hose line E is in a floating state, the section N under the sea is maintained in a smoothly curved state as shown in the figure, and unreasonable force is not applied to the fluid cargo handling hose 20. It is designed to be placed on the bottom of the ocean and not be damaged by wind, waves, or currents.

In addition, as described above, two fluid cargo handling hoses 20 are installed in parallel.
In the underwater section N, they are arranged side by side as shown in Figures 1 and 8, and when the marine fluid cargo handling hose line E is floating, the underwater section N However, even if the fluid cargo handling hoses 20 are curved as shown in FIG.
9) The cargo handling ports 20 are prevented from shifting against each other,
Moreover, in the section where the hose line E for two-fluid cargo handling on the main island floats in the floating state, as shown in Figures 9 and 10,
As shown in the figure, the curvature of each fluid cargo handling hose 20 is arranged in a dark blue pattern, and even if the floating section of the marine fluid cargo handling hose line E is curved due to the influence of wind or tidal current in the floating state, the curvature of each fluid cargo handling hose 20 is The radii are made to match to prevent the respective fluid cargo handling bows 20 from becoming entangled with each other or colliding with each other due to the influence of wind or tidal currents.

Next, the floating and sinking operation of the above-mentioned marine fluid cargo handling boat line E and its floating and sinking process will be explained.

fl, l Ascent operation and ascent process First, when air is injected into the buoyancy adjustment chamber 241 from the air supply and exhaust pipe 242 of the pilot buoy 240, the seawater filling the buoyancy adjustment chamber 241 is caused by this injected air.
The section P that is pushed out from the water pipe 243 and extends from the free end side 20a of the fluid cargo handling hose 20, that is, from the sea surface to the cargo handling port during cargo handling, is shown in FIG. 3 (al). When the air is pressurized into the buoyancy adjustment hose 10 from the air supply/exhaust valve 11 of the buoyancy adjustment port 10, the air is forced into the buoyancy adjustment port 10. The filled seawater is pushed out from the sinking side 10b that allows water to pass through, and the fluid cargo handling hose 20 can be sequentially lifted off the bottom from the free end side 20a as shown in FIG. 4 (al).

(2) Sinking operation and its sinking process First, when the air supply and exhaust valve 11 of the buoyancy adjustment port 10 is opened, the air filled in the buoyancy adjustment hose 10 is pushed out from the air supply and exhaust valve 11 by the water pressure of the seabed. As a result, the fluid cargo handling hose 20 can be sequentially lowered from the lowering side as shown in FIG. 4(b). Next, when the air supply and exhaust pipe 242 of the pilot buoy 240 is opened, the air filled in the buoyancy adjustment chamber 241 is pushed out from the supply and exhaust pipe 242 by the water pressure of the seawater that enters the buoyancy adjustment chamber 241 from the water flow pipe 243. Fluid cargo handling water source 20
The free end side 20a in FIG. 3 (b
As shown in Fig. 1, the bottom can be landed sequentially from the sinking side.

As described above, the present invention provides a buoyancy adjustment chamber and a buoyancy adjustment chamber on the free end side of a fluid cargo handling hose that is capable of floating and sinking and is provided with an on-off valve on the free end side that can be connected to a fluid transport vessel. Since we installed a pilot buoy with a supply and exhaust pipe and a water pipe that communicate with the pilot buoy, when we pressurized air into the buoyancy control chamber from the supply and exhaust pipe of the pilot buoy, the buoyancy control chamber was filled with the injected air. Seawater is pushed out of the water pipe, and the free end side of the fluid cargo handling hose, that is, the section from the sea surface to the fluid loading port of the fluid transport vessel during cargo handling, is sequentially removed from the bottom from the tip side as shown in Figure 3 (al). When the above-mentioned supply and exhaust pipe is opened, the air filled in the buoyancy adjustment chamber is pushed out from the supply and exhaust pipe by the water pressure of the seawater that enters the buoyancy adjustment chamber from the water supply pipe, and the air in the fluid handling hose is The free end side, that is, the section from the sea surface to the fluid loading port of the fluid transport vessel during cargo handling, can be brought to the bottom sequentially from the sinking side as shown in Figure 3 (b). can be floated or submerged as necessary.As a result, the navigation of the ship can be prevented from being obstructed, and the fluid cargo handling hose can be reliably prevented from being damaged by waves during bad weather. .

(bl As mentioned above, when floating a fluid cargo handling hose, it can be floated sequentially from the floating side, and when it is made to sink, it can be made to sink sequentially from the sinking side. As a result, floating and sinking At times, it is possible to reliably prevent the fluid cargo handling hose from rubbing against the seabed and being damaged.
