부산 남외항 대기 정박지 운영 개선에 관한 연구

Abstract

Busan Port opened since 1876 under the name of "Busanpo". It is the first- class trading port in the Port Act and also considered the oldest and the largest port in Republic of Korea. Busan port serves as the gateway to trade and has been growing steadily as the East Asia's hub-port. Busan Port is comprised of the North port, South port, Kamcheon port, Dadeapo port, Busan new Port and Anchorage.

N-Anchorage is being used to wait for schedule or receive oil or change crews. N-anchorage is divided into 5 sub-areas: N-1 ~ N-5. A total of 90 vessels can be anchored according to port laws. Sometimes Anchorage is congested by vessels anchored at the same time.

This study analyzes the present states and characteristics in N-anchorage. Anchorage usage is analyzed in duration of 3 years. Weather conditions and marine accidents in Busan are analyzed for 5 years.

According to this analysis, we found operational risks of the N-anchorage.

The first potential risk is long-term anchoring vessels in N-anchorage. Long-term anchoring vessels include seized vessels, waiting vessels for repair and departure, etc. These vessels lack her operational ability. So, it increased the risk of N-anchorage.

The second potential risk is traffic flow crossing N-anchorage. Traffic flow assessment is implemented by using ES(Environmental Stress) model which is formal assessment model for marine flow situation in the diagnosis system.

This study suggests that N-2 anchorage should be designed a circle designation system for Long-term anchoring vessels, and traffic flow crossing N-anchorage should also be changed traffic flow bypassing to improve the operational risks in N-anchorage.

This suggestions are supported by questionnaire survey and ES model in terms of safety assessment.

Therefore, the study will be improving the navigational safety and reducing the risks in N-anchorage.
