Description

[Detailed Description of the Invention] The present invention relates to an improvement of a hose line for marine fluid cargo handling.

SALM (SINGLE ANCHOR) is generally used for cargo handling of transported fluids such as crude oil between a fluid transport vessel anchored offshore and a base installed on land.
LEG MOORING) and CALM
(CATENERY ANCHOR LEG MOORING)〕
A relay system for marine fluid cargo handling known as

In both of these relay systems, a marine cargo handling relay facility is installed at an offshore cargo handling site, which is connected to a base on land by a submarine transport pipe, and a fluid cargo handling hose is connected to this marine cargo handling relay facility. The free end of the fluid cargo handling hose is connected to the cargo opening of a fluid transport vessel moored at the marine cargo handling relay facility to carry out cargo handling operations.

However, these fluid cargo handling hoses are usually provided with two or more, and moreover, they are long enough to provide sufficient slack between the marine cargo handling relay facility and the fluid transport vessel moored there. ing.

Therefore, during cargo handling, the various fluid cargo handling hoses floating on the sea collide with each other due to the influence of wind and tidal currents, and in extreme cases, they not only become entangled and damaged, but also cause damage as shown in Figure 1. ,
Due to the large curvature, each fluid cargo handling hose Ga
A difference occurs in the radius of curvature Ra and Rb of the hoses Ga and Gb, and as a result, a difference in length occurs at the free end of each fluid handling hose Ga and Gb, making connection work with a fluid transportation vessel difficult, etc. The current situation is that there are various problems.

The problem caused by this difference in radius of curvature occurs when the fluid handling hoses are lined up and connected to each other in order to make them float and sink.
becomes even more prominent.

The present invention was developed as a result of studies to solve the above-mentioned problems.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an excellent marine fluid cargo handling hose line that can uniformize the radius of curvature even when fluid cargo handling hoses are lined up and connected to each other.

That is, in the present invention, a plurality of fluid cargo handling hoses are arranged in a vertical direction with respect to the sea surface on a buoyancy adjustment hose, and the buoyancy adjustment hose and the plurality of fluid cargo handling hoses are connected via a connecting member. The gist of this is that

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

2 to 4 show a hose line for marine fluid cargo handling according to an embodiment of the present invention, and FIG. 2 is an explanatory plan view of a relay system for marine fluid cargo handling using the present hose line for marine fluid cargo handling, Figure 3a is an enlarged front view explanatory view of part A in Figure 2, Figure 3b is Figure 3a
FIG. 4 is an enlarged cross-sectional view of the portion corresponding to FIG. 2A in another embodiment.

In the figure, E indicates a marine fluid cargo handling hose line according to an embodiment of the present invention, in which a plurality of fluid cargo handling hoses 10 are arranged vertically with respect to the sea surface W, and these fluid cargo handling hoses 10 are mutually connected. Coupling member 20
It is constructed by connecting via.

To further explain this structure, in the first embodiment shown in FIGS. 3a and 3b, the present marine fluid cargo handling hose line E is connected to the lower side of a buoyancy adjustment hose 30 whose buoyancy can be adjusted as shown in the figure. Along this, two fluid cargo handling hoses 10 are arranged vertically with respect to the sea surface W, and these are connected to each other by a connecting member 2.
It is composed of koha connected through 0.

Note that, of course, instead of the buoyancy adjustment hose 30, a buoyancy imparting hose whose buoyancy cannot be adjusted may be used.

In addition, in the second embodiment shown in FIG. 4, the marine fluid cargo handling hose line E has a fluid cargo handling hose 10a located at the upper part, that is, on the sea surface side, as shown in the figure.
Buoyancy imparting members 40 are attached at intervals in the longitudinal direction on both left and right sides of the fluid cargo handling hose 10a.
Another fluid cargo handling hose 10b is arranged along the lower side of the hose 10b in a vertical direction with respect to the sea surface W, and these hoses are connected to each other via a connecting member 20.

In each of the above-mentioned embodiments, an example has been described in which two fluid cargo handling hoses are arranged in a vertical direction, but it goes without saying that the number of hoses may be increased as necessary.

Further, in the figure, F is a marine cargo handling relay facility, and S is a fluid transport vessel moored at this marine cargo handling relay facility F.

Since the present invention is configured as described above, it has the following effects. In other words, (1) Since each fluid cargo handling hose is connected to each other, during cargo handling floating on the sea, each fluid cargo handling hose may collide with each other due to the influence of wind or tidal current. It is possible to reliably prevent them from becoming entangled with each other, and to prevent them from being damaged as much as possible.

(2) Since the fluid cargo handling hoses are arranged vertically with respect to the sea surface and connected to each other, when cargo is being handled floating on the sea, each fluid cargo handling hose is Even if it is greatly curved,
The respective radii of curvature can be matched.
As a result, the free ends of each fluid cargo handling hose can be made to coincide with each other, thereby facilitating connection work with a fluid transportation vessel.
