Description

PIPE COUPLING ASSEMBLY FOR LIQUID CARGO}

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.
