Description
The present invention relates to an unloading arm manipulation practice apparatus and method thereof. More specifically, the present invention relates to an apparatus and a method for improving the skill of handling an unloading rock used at the time of LNG carrier entry / departure.
Methane-based natural gas is converted into a liquid state for long-haul transport after a series of purification processes. Liquid natural gas is called LNG (Liquefied Natural Gas) and its volume is reduced to one-sixth of that of natural gas, with a temperature of approximately -162 ° C.
LNG is transported at saturation pressure by LNG-only vessels containing cryogenic cold storage tanks and docked at offshore unloading plants. After arriving at the offshore plant, LNG is stored in onshore LNG tanks through unloading arms and offshore piping.
LNG handling processes of Tongyeong, Pyeongtaek and Incheon takeover bases currently in operation in Korea are operated in a consistent form of LNG unloading, storage, recirculation, boil-off gas treatment and vaporization. At this time, the unloading is made through a plurality of unloading arms using a pump of the LNG vessel. The unloading rock is connected to the delivery pump pipe line of the LNG vessel, and the LNG unloaded from the ship through the unloading arm is transferred to a storage tank on land through a plurality of offshore piping and headers.

However, not only is it almost impossible to practice loading and unloading operations, but due to shifts and the arrival and departure time of flexible LNG vessels, there are not many opportunities to practice loading and unloading.
Therefore, not only are there many skilled unloading rock operators capable of skillfully manipulating the unloading rock during actual LNG unloading work, but there is a problem that a lot of time and money must be put into training a skilled unloading rock operator.
The present invention has been proposed to solve the above problems,
The training cost of training the unloading rock manipulator can be improved by allowing the manipulator practicing the unloading rock maneuver repeatedly to safely carry out the unloading rock maneuver practice using the unloading rock simulation image displayed through the display means. And to save time and the like, and to improve the efficiency and safety of unloading rock work with high difficulty to provide a natural gas to the consumer in a stable and economical way.
The unloading arm manipulation practice apparatus according to an embodiment of the present invention, the user controls the control signal of any one of the outboard arm unfolding, outboard arm folding, inboard arm raising, and inboard arm lowering control signal for the unloading arm manipulation practice.

It is characterized by processing.
The controller may be further configured to initialize the simulation image for the loading arm to a preset simulation image when an initialization request for the loading arm manipulation exercise is received through the input unit.
In addition, when the outboard arm spreading control signal is input through the input unit, the simulation processing unit changes a simulation image of the outboard arm of the unloading arm to move forward step by step, and controls the outboard arm folding through the input unit. When a signal is input, the simulation image of the outboard arm of the unloading arm is changed to fall backward step by step.
In addition, when the inboard arm lowering control signal is input through the input unit, the simulation processor changes a simulation image of the inboard arm of the unloading arm to descend in stages, and controls the inboard arm raising through the input unit. When the signal is input, the simulation image for the inboard arm of the unloading arm is characterized in that it changes stepwise backward.
