A Study on the Sector Division for Effective Vessel Traffic Service : Focused on Daesan, Pyeongtaek and Inchon Harbour

The national VTS was launched in 1993, and has adopted a harbour-oriented control method which is unable to consider enough characteristics of its work. However, for the past 17 years, the characteristics has changed due to increased amount of vessels. Up to now the domestic Vessel Traffic Service has adopted harbour-oriented control method which is unable to consider enough characteristics of its work. However, developed countries have carried out waters-oriented control method, according to the using areas of ships, to be well considered the characteristics of control for increasing efficiency of it. Especially, VTS of Daesan, Pyeongtaek and Inchon harbour can have confusions of control because of overlapped service areas of it. Therefore, in this paper suggested a new Sector Division that the relevants waters is divided into 3 operational Regions and these are divided into nine sectors again, for the purpose of improving the efficiency and the concentration of VTS. Recently for the purpose of increasing the safety at sea and the efficiency of harbour administration, many countries has carried out Vessel Traffic Service(VTS) in the waters where the amount of traffic is concentrated, and has extended the range of VTS gradually. The main function of the VTS is to eliminate of the risk of traffic accidents in advance by doing close observation of ship's movements and exchanging the safe informations concerned about traffic management with each user of harbour. It is seriously affected by range, vessel traffic volume, the amount of wire traffic and the number of VTS operators due to the nature of controlling traffic. Up to the now the domestic Vessel Traffic Service has adopted a harbour-oriented control method which is unable to consider enough characteristics of its work. However, developed countries have carried out ship's using the water area-oriented control method to be well considered the characteristics of control for increasing efficiency of it. Especially, Daesan VTS, Pyeongtaek VTS and Inchon VTS can have confusions of control because of overlapped service areas of them. It was reported that the volume of vessel traffic in these harbours is the second largest after Pusan harbour(Park, 2008). Therefore, in this paper studied Sector Division control method to improve the efficiency and the concentration of VTS and to reduce workload of traffic control about the relevant waters.
