A Simulation Study on the Improvement of the Waterway of Kwangyang Harbour

Kwangyang harbour has been developed very rapidly and has 20 berths including 2 for 250,000DWT bulk carriers at the terminal of Kwangyang Steel Company only. In addition to this, the port is developing a container terminal with 10 berths for 50,000GRT container ships, the construction of which is scheduled to be finished in the year 2000. Because of these development, it has been pointed out that the existing waterways are not wide and safe enough for the new large ships to be catered for. This work, therefore, aimed to examine the naviga-tional safety of the waterways of Kwangyang Harbour, and to suggest how to improve the existing water-ways for the large ships to be introduced in the near future. In examining the safety of the existing and newly suggested waterways, waterway design simulation methodology has been applied. From this study, it has been suggested that the No.4 navigational channel has to be dredged to the depth of 22.5 meters and used as an entrance channel only, while the No.3 channel is used as an exit channel. Additionally, a new waterway has been recommended to be established over the Myodo Island for the container ships which will use the new terminal, the width of which has been recommended to be 400 meters with 440 meters from the bend area.
