Description

Bunkering Station

The present invention relates to a bunkering station.

Bunkering mainly refers to the storage and transmission of ship fuel oil known as bunker oil, and recently, the LNG fuel propulsion ship market and other bunkering markets have grown significantly as the International Maritime Organization (IMO)'s regulations on ship emissions have been strengthened. As the use of LNG increases according to the trend, the transmission and supply of LNG fuel is also included as bunkering.

LNG bunkering is performed by supplying fuel to LNG fuel propulsion vessels using bunkering vessels, bunkering bases, and bunkering floaters.

In the case of a bunkering ship, you can directly visit an LNG fuel propulsion ship to supply fuel.However, while there is an advantage of being able to visit any sea area, in addition to the LNG fuel cost, additional costs such as fare due to the movement of the bunkering ship are added, or depending on the size of the bunkering ship, etc. There is a disadvantage in that there is a limitation in transferring side by side from the side wall, or there is a limitation in providing a total solution due to insufficient facilities of the bunkering ship.

In the case of a bunkering base, the LNG fuel propulsion ship directly comes to the terminal and refues it like an LNG onshore terminal, but it has the advantage that it is a proven method, but the limitations of land space due to the construction of the base (various sizes and ship types can be docked) Also, there is a disadvantage that the LNG fuel propulsion ship has to go to the terminal.

In the case of a bunkering plotter, it is possible to supply LNG to an LNG fuel propulsion ship as a fixed structure at sea, and is expected to overcome the disadvantages of bunkering ships and bunkering bases. In other words, it is possible to supply LNG to several ships of various ship types at the same time, and to provide a total solution such as compressor-related equipment, re-liquefaction and re-gas unit installation, etc. It is installed close to the route of the LNG fuel propulsion ship to minimize movement for LNG fueling, and it is possible to diversify the size and shape to solve the restrictions related to transmission, and LNG loading through general LNG carriers is possible, and by installation at sea. It has commercial use value such as solving local civil complaints and optimizing safety due to unmanned application and being able to modernize, and various research and development on floating type offshore structures such as bunkering plotters are being conducted.

The present invention was created to solve the problems of the prior art as described above, and an object of the present invention is to secure the stability of mooring while allowing a number of unspecified ships of various sizes to simultaneously load and unload (Loading & Offloading) work. It is to provide a bunkering station that allows you to do it.
