Description

Mobile unloading vessel and synchronization system for it {VESSEL FOR MOBILE UNLOADING AND SYNCHRONIZING SYSTEM FOR THE SAME}

The present invention relates to a container ship unloading system, and more particularly to a vessel capable of mobile unloading and a synchronization system for the same.

In the past, 5,000 to 6,000 TEU container ships were mostly used, but in recent years, 14,000 TEU container ships have been built and 18,000 TEU container ships are being built. In the case of large container ships, the landing time for unloading will be longer, which is directly related to the cost of the shipping company. In addition, since there are not many ports with the capacity to accommodate large container ships, improvement of the unloading system of large container ships is required.

An object of the present invention is to provide a vessel that performs the unloading while moving with the container ship in order to reduce the unloading time of the container ship at the port.

It is another object of the present invention to provide a synchronization system for a ship that performs unloading while moving with a container ship.

In order to achieve the object of the present invention described above,

According to one aspect of the invention, the position information measuring unit for providing position information of the ship; A communication module for obtaining information of the other ship through communication with another ship; Thrust unit for adjusting the movement of the ship; And a control unit for controlling the thrust unit, wherein the control unit outputs a control signal for synchronizing a movement with the other vessel to the thrust unit using signals input from the position information measuring unit and the communication module. A synchronization system is provided.

The position information measuring unit may include a GPS and a gyroscope. In this case, the position information measuring unit may further include a relative position measuring sensor for measuring a relative position with the other vessel. The relative position measurement sensor may include a laser measurement sensor and an acoustic sensor.

The ship synchronization system may further include a fender monitoring sensor for checking a state of the fender provided in the ship and outputting it to the controller, wherein the fender monitoring sensor may measure the pressure applied to the fender.

The thrust portion may include a propeller, a thruster, and a rudder.

The vessel synchronization system may further include an automatic ballast system controlled by the controller.

In order to achieve the above object,

According to another aspect of the present invention, there is provided a ship for unloading cargo from a moving container ship, comprising: a crane for carrying cargo; And a synchronization system for synchronizing movement with the container ship.

The mobile unloading vessel may further include a fender for avoiding collision with the container ship.

According to the present invention, all of the objects of the present invention described above can be achieved. Specifically, since the unloading is carried out before the container ship enters the port time of the container ship can be reduced.

In addition, it can be unloaded even in ports where large container ships cannot enter, so the operation range of container ships is increased and the use range of ports is widened.

In the present embodiment, the fender monitoring sensor 134 will be described as being a pressure sensor for measuring the pressure applied to the fender (120 in FIG. 1).

The communication module 135 obtains information of the work target container ship C necessary for synchronization through communication with the work target container ship C from the work target container ship C, and outputs it to the controller 136. . The information of the work object container line C obtained through the communication module 135 includes the absolute position, the heading angle, and the draft of the work object container line C. Through the communication module 135, the mobile unloading vessel (100 in FIG. 1) may share information with the working container ship (C).

The controller 136 is input from the GPS 131, the gyroscope 131a, the first relative position measurement sensor 132, the second relative position measurement sensor 133, the fender monitoring sensor 134, and the communication module 135. The propeller 138, the thruster 139, the rudder 140 control signals for synchronizing the movement of the mobile unloading vessel (100 in FIG. 1) with the movement of the container vessel (FIG. 1C) using the collected data. And the automatic ballast system 141. In this embodiment, the controller 136 is described as being implemented as a programmable logic controller (PLC).

The operation console 137 is a device that allows an operator to input a command to the controller 136.

Propeller 138 controls the forward and backward movement of the mobile unloading vessel (100 in FIG. 1). The propeller 138 is controlled by the controller 136 so that the mobile unloading vessel (100 in FIG. 1) moves at the same speed as the container ship to be worked (C in FIG. 1).

And, fender state checking step (S40).

In the same speed maintaining step (S10), the mobile unloading vessel (100 in FIG. 1) is controlled to move at the same speed as the working container ship (C in FIG. 1). The same speed maintaining step (S10) is such that a difference does not occur between the moving speed of the work target container ship (C of FIG. 1) input through the communication module 135 and the moving speed of the moving unloading vessel (100 of FIG. 1). The controller 136 of FIG. 2 may be performed by outputting an appropriate control signal to the propeller 138 of FIG.

In the constant distance maintaining step (S20), the mobile unloading vessel (100 in FIG. 1) is controlled to maintain a constant distance from the working container ship (C in FIG. 1). Constant distance maintenance step (S20) is the controller (136 in FIG. 2) the thruster (139 in FIG. 2) so that the distance between the mobile unloading vessel (100 in FIG. 1) and the container ship (C in FIG. 1) is kept constant. And a proper control signal to the rudder (140 in FIG. 2).

In draft adjustment step S30, the draft of the mobile unloading vessel (100 of FIG. 1) is matched with the draft of the container ship to be worked (C of FIG. 1). The draft adjustment step S30 may be performed by the controller 136 of FIG. 2 outputting an appropriate control signal to the automatic ballast system 141 of FIG.

In the fender state checking step S40, the pressure applied to the fender (120 in FIG. 1) is measured. In case of excessive pressure on the fender (120 in FIG. 1), the controller (136 in FIG. 2) causes the controller (FIG. 2 in FIG. 1) to move away from the unloading vessel (100 in FIG. 1) and the container ship (C in FIG. 1). 136 may be performed by outputting an appropriate control signal to the thruster (139 in FIG. 2).

In FIG. 3, each step is shown to be sequentially, but this is for ease of description. Alternatively, each step may be performed independently or simultaneously in a different order.
