Abstract
Description
The present invention relates to a pipe connecting structure, and more particularly, to a pipe connecting structure for liquid cargo used in the transfer of liquid cargo such as fuel oil.
Recently, various offshore oil loading systems such as bunkering terminals, floating production storage and offloading (FPSO), and shuttle tankers have been in operation. In such a marine crude oil loading system, since the crude oil is transported in the sea, the pipe connection and disconnection operations for the crude oil are repeated as necessary.
For example, in the case of bunkering terminals, the fueling vessel docks with the bunkering terminal in which fuel oil is stored, and then provides a hose or pipe to the bunkering terminal through a loading arm, and the like. In connection, the fuel oil is transferred to the fueling vessel. In addition, when the transfer of the fuel oil is completed, the hose or pipe as described above is separated from the piping equipment of the bunkering terminal again, in order to supply the fuel oil to the other fueling vessel, the connection and disconnection of the pipe is repeatedly performed.
At this time, the connection or disconnection of the pipe of the bunkering terminal and the pipe provided in the fueling vessel is usually made by a worker's manual work. In other words, the pipe connection is made by the operator lifts the pipe provided from the fueling vessel to the height of the pipe installed in the bunkering terminal and bolts the flanges of the pipes together. The worker is put in and there is a high risk of a safety accident during work.
On the other hand, after the transfer of the fuel oil is completed, the operation to separate the pipe is made again, at this time, the fuel oil remaining in the pipe flows to the bottom surface to contaminate the bottom surface frequently. That is, even after the transfer is completed, fuel oil and the like remain in the pipe. When the pipe is separated, the remaining fuel oil falls to the floor as described above, contaminating the floor or causing a safety accident such as a sliding accident. Similarly, Korean Utility Model Publication No. 20-0445284 discloses a crude oil loading system for a shuttle tanker to prevent crude oil from falling on the sea, but it is difficult to apply to a bunkering terminal.
Embodiments of the present invention, while facilitating the coupling or separation operation of the pipe, while providing a pipe connection structure for the liquid cargo that can effectively collect the liquid leakage leaked when the separation of the pipe.
According to an aspect of the invention, the spaced apart from the bottom surface, the first piping unit having a first flange; And a second piping unit having a second flange coupled to the first flange, the second piping unit being coupled to and detachable from the first piping unit, wherein the first flange is coupled to or coupled to the second piping unit. When the separation may be provided with a pipe connecting structure for a liquid cargo provided with a support piece which is supported by seating the second flange.
In this case, the support piece is provided in the lower portion of the first flange, may be formed in an arc shape along the outer periphery of the first flange, is formed to be symmetrical with respect to the lowest center point of the first flange, the center angle It can be formed from 60 degrees to 180 degrees.
In addition, the support piece is formed extending in the fastening direction of the second piping unit, the length from the end of the first flange to the end of the support piece may be formed larger than the thickness of the second flange.
In addition, the support piece, the holding portion for collecting the liquefied leakage when the separation of the second piping unit; A drainage hole for discharging the liquid cargo collected in the solid portion; and a drain valve for opening and closing the drainage hole.
On the other hand, the first piping unit may include a main conveying line provided in the bunkering terminal, the second piping unit may include a pressure reducing piece fastened to the main conveying line.
The first piping unit may include a pressure reducing piece fastened to the main conveying line of the bunkering terminal, and the second piping unit may include a flexible pipe provided from a marine vessel and fastened to the pressure reducing piece. .
According to embodiments of the present invention, the liquid connecting pipe connection structure may support the second piping unit by the support piece provided in the first piping unit, thereby facilitating the joining or separating of the first and second piping units. have.
In addition, the liquid connecting pipe connection structure according to the embodiments of the present invention, the liquid liquefied leaking when the separation of the second piping unit is collected through the support piece, so that the liquid cargo such as fuel oil flows down to the bottom surface Can be prevented.

5 is a perspective view showing a state in which the piping connection structure for a liquid cargo according to an embodiment of the present invention is applied to the bunkering terminal equipment.
Referring to Figure 5, the bunkering terminal facility may be installed a main feed line (M) for the transfer of fuel oil. The main transfer line (M) is connected to the storage facility in the bunkering terminal, to receive fuel oil from the marine vessel, or to supply the stored fuel oil to the marine vessel.
On the other hand, in order to transfer the fuel oil between the vessel and the bunkering terminal of the sea, the flexible pipe (P) may be connected to the main transfer line (M). Flexible piping (P) is provided to the bunkering terminal in the marine vessel through a loading arm (loading arm), etc., is connected to the main transfer line (M) to transfer the fuel oil between the bunkering terminal and the marine vessel.
In addition, the main transfer line (M) and the flexible pipe (P) may be connected via a pressure reducing piece (R). Decompression piece (R) is formed in a tapered shape to one side, it is to control the transfer pressure between the main transfer line (M) and the flexible pipe (P).
Typically, the main feed line (M) is formed of a structure fixedly installed in the bunkering terminal, the decompression piece (R) and the flexible pipe (P) is to be used in connection with the main feed line (M), respectively, during the transfer of fuel oil. . Therefore, the worker repeatedly lifts up and combines or separates the decompression pieces R and the flexible pipes P, which are heavy materials, each time the fuel oil is transferred.
