  • After World Trade Center's Terror in 2001 and promulgating Maritime Transportation Security Act (MTSA, 2002) and Security and Accountability For Every Port Act (SAFE Port Act, 2006) in the United States, most of the attention on security of international transportation including marine carrier and facility has focused increasingly. Inspection stations in foreign seaport terminal including Busan, South Korea, have been installed by Container Security Initiative (CSI) and Customs Trade Partnership against Terrorism (C-TPAT). The inspection station, however, may directly and indirectly affect delay of truck turnaround time in the seaport, especially high and severe level of security. This paper was analysed a risk for the additional average delay of truck turnaround time incurring by the inspection station under the all level of security, C-TPAT and CSI. As a result of this risk analysis, the higher weighted inspection time based on raising security level, the less number of trucks to be inspected, which will derive high delay in the inspection station.

  • Gate operations are very important as they are the starting point for export containers and the end point for import containers as far as checking and control exercised by terminal operators are concerned. The objective of this paper is to propose the design of separated gate system in order to reduce the truck turnaround time and to distribute the truck traffic volume in port container terminal. Because of a lot of container load and unload within short term, many trucks have to pass the gate at a time. This study suggests the separated gate system as an efficient design for gate operation considering integration of two individual berth.

  • With the recent port environment, the integration of the separated berth is being actively progressed and the necessity of integration has been strengthening. Therefore, the application of existing gates have to review in order to reduce the truck turnaround time and to distribute the truck traffic volume in port container terminal. This paper analyzed the operation impact both the integrated gate and the separated gates. As the result of the analysis, this study suggests the separated gate system as an efficient design for gate operation considering integration of two individual berth.

  • To improve competitive power of the container terminal, we must enhance the yark efficiency of a domestic container terminal in the chronic shortage situation, Therefore, we investigate the basic concept and the expected effect delivery reservation when applying at existing container terminal.

  • This paper aims to compare four operating priority rules of RMGC (Rail Mounted Gantry Crane) used in semi-automated container terminal. The four priority rules employed in this paper are FCFS (First-come-first-served), LCFS (Last-come-first-served), TOS (Turn-over-served) and NFS (Nearest-first-served). And to compare the four operating priority rules, this paper analyzed productivity of RMGC and CC (Container Crane), waiting time of YT (Yard Truck) and RT (Road Truck) in container yard, and turnaround time of RT in container terminal of each priority rule by using stevedoring simulation. As a result, NFS was evaluated as the best rule to improve the overall productivity of container terminal in terms of all criteria.

  • A basic concept of TAS(Tractor Appointment System), which not only enhances the terminal productivity, but also yields higher efficiency of domestic CT(Container Terminal), is developed in this paper for CT to more competitive and serviceable. To analyze the effects of TAS when applied to the existing four-tier CT, a quantitative analysis is performed. The results showed that the number of rehandling time of CT has been significantly decreased, the efficiency of CT increased, and the flow time of trucks in CT reduced in a great deal
