Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cargo handling facility for fluids and cargo handling methods for handling fluids such as liquids and granular materials in rivers and harbors from the ship side to the land side, or from the land side to the ship side or from the ship to the ship, and The present invention relates to a float fluid receptor.
[0002]
[Prior art]
In the conventional rivers and harbors, the handling of the above-mentioned fluid-like material is carried out by the ship-side transport pipe provided on the ship-side, one end of which is connected to the ship-side storage tank, the other end of the ship-side transport pipe, and the land-side One end of a telescopic loading arm provided on the pier is connected via a slidable swivel, and the other end of the loading arm is connected to a land-side storage tank via a land-side transport pipe. It is carried out from one storage tank to the other storage tank by the air pressure of a fluid pump or a compressor.
[0003]
On the other hand, the ship being handled is anchored by a mooring anchor or a mooring line between the ship and the pier, and anchored at a fixed position as much as possible so that the cargo handling is performed smoothly. .
[0004]
[Problems to be solved by the invention]
However, due to the occurrence of unforeseen conditions such as aging and typhoons due to long-term use, the position of the anchoring anchor will shift on the seabed, the mooring line will break and the anchoring position cannot be maintained, There is a risk of leaving the pier, or depending on the situation, about 30m to 40m.
In addition, when the ship being handled leaves the pier, the connection angle between the inboard and the outboard constituting the loading arm is widened as a result. The other side of the loading arm connected to the other end of the ship-side transport pipe and the other end of the loading arm is connected to the other end of the ship-side transport pipe. The above-mentioned connecting portion is disengaged, and the tip of the loading arm is inclined and falls toward the sea surface.
[0005]
As a result, the fluid-like material in the inboard and outboard of the loading arm during cargo handling falls to the sea surface or is mixed into seawater.
And when the above-mentioned fluid is heavy crude oil, the heavy crude oil is lighter than seawater, so it floats on the sea surface. There are various means such as surrounding and collecting the heavy crude oil. However, in the case of an emergency as described above, there is a risk that it may be difficult to collect or the sea may be contaminated.
[0006]
Moreover, as an alternative fuel for heavy crude oil in recent years, for example, Olimar John crude oil (hereinafter simply referred to as "Orimarujon") mined in the Venezuela region of South America has a considerable amount of reserves, and has attracted attention as an alternative fuel in various places. Research is underway.
When unloading the above-mentioned olimarsion as the above-mentioned fluid is carried out on the surface of a river or a port, the above-mentioned unexpected condition occurs, for example, the tether is cut and the ship is separated from the pier during the loading. As you go to the shore, the connecting part between the loading arm and the ship-side transport pipe will eventually come off, and when the tip of the loading arm tilts and tilts toward the sea surface, In addition, all of the unmarried cargo in the loading arm falls on the sea surface.
[0007]
And the specific gravity of the above-mentioned olimarsion is very similar to the specific gravity of seawater, almost close to the specific gravity of seawater, and easily mixed with seawater.
On the other hand, since the surfactant contained in the above-mentioned oral emulsion is a substance that makes it easy to dissolve the oral emulsion in the seawater, when the above-mentioned oral emulsion falls into the seawater, it is diffused in the seawater due to tidal currents and waves. The fall of the olymarsion is not only recoverable, but may lead to contamination of seawater as described above.
[0008]
In addition, when the fluid is a granular material such as rice, wheat, or beans, or a powder such as wheat flour or cement, or a powder such as iron ore or a chemical substance, the fluid is dropped by dropping on the sea surface. Since the above-mentioned fluid-like matter is diffused by tidal currents and waves, it may be difficult to recover or lead to contamination of seawater.
The present invention has been devised in view of such problems, and when carrying a cargo of a fluid-like material in a river or a port, a ship-side transport pipe connected to a ship-side storage tank and a land-side storage tank are provided. A float-type fluid receptor that forms a transport pipe connecting part that connects the land-side transport pipe connected to the ship and follows the ship and the transport pipe connecting part when the ship leaves the shore. When a force exceeding the expansion / contraction limit of the conveyance expansion / contraction pipe provided on at least one of the two conveyance pipes is applied, the connecting portion is detached, and the conveyance pipe is inclined in the water surface direction, so that the ship and the both The handling of fluid-like material that prevents the contamination of seawater by receiving the fluid-like material falling from the detached conveyance pipe by the float-type fluid-like material receiver connected so as to follow the connecting portion of the conveyance pipe.
