Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in marine fluid handling hose lines.

According to the research results of the inventors of the present invention, the important points of the hose line for fluid cargo handling between Japan and China are as follows. That is, (al) To enable the fluid cargo handling hose to float or sink as necessary so as not to impede the navigation of the ship, and to prevent the fluid cargo handling hose from being damaged by waves during bad weather.

(bl At the time of floating and sinking mentioned above, the fluid cargo handling (1
) To prevent the hose from rubbing against the seabed and damaging it.

However, the current situation is that no conventional hose line for marine fluid cargo handling has yet been developed that satisfies each of the above-mentioned points.

Therefore, an object of the present invention is to provide an excellent hose line for marine fluid cargo handling that can satisfy all the important points of the marine fluid cargo handling hose line described above.

That is, the present invention provides a marine fluid cargo handling system characterized in that a buoyancy adjustment hose that is equipped with a supply/exhaust valve on the floating side and allows water to pass through the sinking side is attached along the required floating/sinking section of the fluid cargo handling hose. The gist of this article is the hose line for use.

Hereinafter, the present invention will be specifically described by way of examples with reference to the drawings.

Figures 1 to 7 show how the hose line for marine fluid cargo handling according to the present invention is attached to a single point mooring buoy for marine fluid cargo handling (SALM).

In the figure, E is a two-fluid cargo handling port line made of an embodiment of the present invention, in which a buoyancy adjustment hose 10 is attached with a supply/exhaust valve port on the floating side 10a and allows water to pass through the sinking side 10b. It is constructed by attaching it along the required floating/sinking section M of the port 20 for use.

As shown in Figures 1 and 2, a single-point mooring buoy F for fluid cargo handling using two connected hose lines E for marine fluid cargo handling is installed on the seabed and connected to a base on land. a base Fb to which a communicating fluid transport hose Fa is connected;
The marine fluid cargo handling hose line E is rotatably attached to the upper part of this base Fb (3).
A rotary joint Fc to which the base Ea of the rotary joint Fc is connected, and this rotary joint F
A fluid transport vessel (not shown) is moored to this mooring buoy Fe and is moored from a base (not shown) on land-1- to Said fluid transport port Fa-base lb-rotating bed 1! Hand Fc - Marine fluid cargo handling hose line: Load the fluid to be transported such as crude oil onto the fluid transport ship, or from the fluid transport ship to the port line I for every upper fluid loading stage.

The fluid to be transported, such as crude oil, can be unloaded to the land base via the one-rotation joint Fc, the base fib, and the fluid transport hose Fa.

Next, to explain in more detail the port line E for marine fluid cargo handling described above, in this embodiment, as shown in FIGS. A buoyancy adjustment hose 10 that allows water to pass through and an on-off valve 21 (4) that can be connected to a fluid cargo handling pipe (not shown) of the fluid transport vessel on the free end side 20a are attached to the base together with I/H. The side 20h is connected to the single point mooring buoy 1 for marine fluid cargo handling. It consists of a fluid cargo handling hose 20 connected to a rotary joint Fc via an on-off valve 22,
It is constructed by attaching the buoyancy adjustment hose 10 along the required floating/sinking section M of the fluid cargo handling hose 20.

In the present embodiment, the buoyancy adjustment hose 10 has a diameter that varies both when air is pressurized into the interior through the feeder 111'Jr 11 and buoyancy is imparted, and when the air is removed and seawater enters the interior. There is almost no change in the hose structure used. In this embodiment, an on-off valve 12 is provided on the sinking side 10b, which has a water flow capacity of 1 iJ. However, this on-off valve 12 is not necessarily required, and it goes without saying that it may be in the closed state.

Further, as shown in FIG. 1, a pilot buoy 14 is attached to the air supply/exhaust valve 11 provided on the floating side 10a of the buoyancy adjustment port 10 via a lead wire 13. Ho (5) Sending/exhausting valve 11 that is closed when the line E is sinking
The subsidence position can be easily confirmed. Of course, the pilot buoy 14 is provided with a supply/exhaust valve, and the lead wire 13 is provided with an air supply hose, through which air is forcefully delivered into the buoyancy adjustment hose 10 to make it float. You can do it like this.

In this embodiment, as shown in FIGS. 4 to 7, the fluid cargo handling hose 20 is removed as a pair along the buoyancy adjustment hose 10 described above via a connector 30.
I'm being kicked.

Further, as shown in FIG. 1, a pilot buoy 24 is attached to the on-off valve 21 attached to the free end side 20a of the fluid cargo handling hose 20 via a lead wire 23.

The pilot buoy 24 is provided with a direct supply/exhaust valve and a buoyancy adjustment chamber inside, and air is forced into the buoyancy adjustment chamber through this supply/exhaust valve to provide buoyancy and perform fluid cargo handling. The free end side 20a of the use port 20 may be bottomed out from the tip (6).

Furthermore, when air is forced into the buoyancy adjustment port 10 to float the port line E for fluid cargo handling, the port 20 for fluid loading l-1f is shown in FIG.
．． Floating bodies 40 are attached at intervals to a section N in the sea, that is, a section N from the section floating on the sea to the rotary joint Fc. As shown in the figure, the section N under the sea is maintained in a smooth bare state to prevent excessive force from acting on the fluid cargo handling hose 20 or damage caused by wind waves and currents due to it landing on the seabed. ing.

In addition, as described above, two ports 20 for fluid cargo handling are arranged in parallel.
In the section N in the sea, they are arranged side by side as shown in Figs. 1 and 5, and in the floating state of the marine fluid cargo handling hose line E, Even if the section N is curved as shown in FIG. 1, the curvature radius of each fluid cargo handling hose 20 is made to match
Each method (7) The hose 20 for cargo handling is designed to prevent it from slipping on the ground.
Moreover, in the floating state of this fluid cargo handling hose line E? As shown in FIGS. 6 and 7, the floating section I7 is arranged vertically, and when the marine fluid cargo handling hose line E is in the 41 state, the floating section I7 is free from wind and tidal currents. Even if the fluid cargo handling hoses 20 are curved due to the effects of That's how it is.

As described above, the present invention has a buoyancy adjustment port that allows water to flow through the sinking side while attaching a supply/exhaust valve on the floating side, and is attached at -υ along the required floating/sinking section of the fluid cargo handling hose. When air is forced into the buoyancy adjustment port from the above-mentioned supply/exhaust valve, the seawater filled in the buoyancy adjustment port is pushed out from the sinking side that allows water to flow through it. As shown in Figure 3(a), the fluid cargo handling boce line has a thickness of -1-(8
) When the above-mentioned supply/exhaust valve is opened, the air filled in the buoyancy adjustment port is pushed out from the supply/exhaust valve by the water pressure on the seabed, and the fluid handling hose The line can be made to sink sequentially from the sinking side as shown in FIG. 3(b). Therefore, it is possible to float or sink the fluid cargo handling hose as needed. Damage to the fluid cargo handling hose caused by waves of time can be reliably prevented.

ibl l: As mentioned above, when floating a fluid cargo handling hose, it can be floated sequentially from the 2nd side, and when it is sinking, it can be floated 1.1! Therefore, it is possible to sink sequentially. As a result, it is possible to prevent the fluid loading port from rubbing against the bottom of the tank and damaging it when the tank sinks.
