Real-time monitoring of berthing/deberthing operations process for entering/leaving vessels using VTS system in Busan northern harbor, Korea

Abstract

The process of berthing/deberthing operations for entering/leaving vessels in Busan northern harbor wasanalyzed and evaluated by using an integrated VTS(vessel traffic service) system installed in the ship trainingcenter of Pukyong National University, Busan, Korea. The integrated VTS system used in this study wasconsisted of ARPA radar, ECDIS(electronic chart display and information system), backup(recording) system,CCTV(closed-circuit television) camera system, gyro-compass, differential GPS receiver, anemometer,AIS(automatic identification system), VHF(very high frequency) communication system, etc. The network ofthese systems was designed to communicate with each other automatically and to exchange the criticalinformation about the course, speed, position and intended routes of other traffic vessels in the navigationalchannel and Busan northern harbor. To evaluate quantitatively the overall dynamic situation such asmaneuvering motions for target vessel and its tugboats while in transit to and from the berth structure inside aharbor, all traffic information in Busan northern harbor was automatically acquired, displayed, evaluated andrecorded. The results obtained in this study suggest that the real-time tracking information of traffic vesselsacquired by using an integrated VTS system can be used as a useful reference data in evaluating and analyzingexactly the dynamic situation such as the collision between ship and berth structure, in the process ofberthing/deberthing operations for entering/leaving vessels in the confined waters and harbor.Key words : Berthing/deberthing operations, VTS system, Busan northern harbor, Real-time tracking
