From a historical perspective, the 21st century will usher in a fourth wave of the ocean age, or ocean century. World trade has been increasing continuously in total volume, on the other hand, environmental protection on sea and conservation of fishery resources has been rising up the major issue. All of the world are pushing their efforts two major purposes to the full, one is taking competitive place in marine transportation throughout the world and another is environment protection.
Based on geographical advantages, locating in the center of the world's trunk routes, Korea has driven 'modernization and expansion of port facilities' to become a marine superpower in the New Ocean Age. At the same time, in order to actively correspond to the changes in the world marine environment, PTMS (Port Traffic Management System) has been implemented in 1993 and established in 14 ports of Korea by 1998.
PTMS is integrated marine traffic control system and has been evaluated revolutionary effective in reducing marine casualties from other countries such as U.K since 1972 and Japan after 1977. Since 1998 in Korea ports, it's apparent that the result of 2 years' operation has played major role in improving safety and protecting coastal environment so far in Korea.
Also, Pusan Port as world leading port put its all effort in bring more ocean going vessels and securing their traffic route by providing them more information related to marine traffics through PTMS in port. During two years of operation, statistics of marine traffic accidents showed that many dynamic casualties such as collisions, groundings, and rammings has been decreased. However, due to increasing cargo volume, limited water area and unpredictable weather condition, potential risks still exist high.
In this paper, in order to maximize efficiency of PTMS and reduce various risks finally in the future, we examine PTMS addressable, non-addressable factors and the operational results in detail, and design suitable operational methods in Pusan Port.
