Recently, there have occurred many marine casualties and oil spills in coastal water which cause the loss of human lives, properties and marine environment. Especially it is a characteristic oil pollution spreads to a wider range of property and damages to the marine environment. These marine casualties have increased in coastal water out of VTS(Vessel Traffic Service) area marine traffic needs to be managed in coastal water to prevent marine casualties.
It is considered that marine traffic management system in Korea needs to control marine traffic in habour water as well as territorial waters and EEZ waters. Therefore, it is required to improve the marine traffic management system so that we prevent marine casualties and to improve capability of accidents response and management.
VTS generally contributes to the safety of life at sea, safety and efficiency of navigation, the protection of the marine environment, the adjacent shore area, work sites, and offshore installations form possible adverse effects of maritime traffic.
Recently, the function of VTS has been enlarged to VTMIS(Vessel Traffic Management & Information System) which provides marine safety information related to improve the safety, security, efficiency in existing functions in addition to providing information of weather, AtoN, port information.
The IALA eNAV sub-committee has developed the strategy of e-Navigation from 2007. Also the IMO defined e-Navigation is the collection, integration and display of maritime information onboard and ashore by electronic means to enhance berth-to-berth navigation and related services, safety and security at sea and protection of the marine environment. The e-Navigation will influence and change maritime traffic management system by efficiently applying modern digital technology and communication architecture.
It has been carried out analyzing technology trends of international maritime organizations and advanced countries related to maritime traffic management system, also investigated situation of domestic system. This thesis presented improvement of maritime traffic management system with this result.
As the result, the e-VTS was proposed in this study to improve the efficiency of maritime traffic management system in Korea. Korea VTS currently has been consisted to thirteen harbor VTS and two coastal VTS. The proposed system includes 3 layered system, such as local VTS, regional VTS and national VTS.
e-VTS expands the controlling and managing area of VTS to coastal water. It will provide vessel traffic monitoring service not only in the Korean waters but also in the adjacent Chinese & Japanese waters and carry out continuous surveillance of vessel traffic by the introduce of e-VTS system. Also the national VTS is installed in the central component authority which provides information of entire marine traffic situation by vessel position reporting from AIS, LRIT, VMS and supervising all VTS system. And National VTS carries out a role of gateway to exchange information of LRIT, AIS, SAR as carrying a role of VTMIS.
This paper also proposed a Global VTS which shares and exchanges the related VTS information among adjacent countries. The Global VTS Network exchanges VTS tracks between National VTS data centers of Korea, China and Japan by inter-VTS Data Exchange Protocol based on network/internet solution. Mutual exchange of VTS data such as identification, position and time of vessels sailing in adjacent waters between countries is needed to enhance the safety and efficiency of maritime traffic.
This paper consists of six chapters including chapter 1 introduction. Chapter 2 analyzed technology trends of IMO, IALA, e-Navigation, MarNIS. Chapter 3 carried out analyzing the status of maritime traffic management system in Korea and the developed countries. Chapter 4 gave improvement of maritime traffic management system with problems in Korea. Chapter 5 shows drawing the e-VTS and global VTS system based on the state of the art techniques. At last, chapter 6 summarized and concludes the whole paper contents.
