This paper studies on participation model of the terminal operator in enchancing competitiveness of Korean ship owners, terminal operators and Busan Port. Particularly, it would be focused on Busan container terminal that is being expaned through Busan New Port project. Recently, Exsiting "North Port Terminal" is being closed down due to redevelopment and instead, "New Port" terminal is expanding. However, although the port project is a national project, foreign capital accounts for more than half of Busan's container terminal operators, and Korean shipping companies and operators are at a disadvantage. Busan Port also has good infrastructure and geographical strength compared to competitive ports, but it is somewhat lacking in terms of profitability and competitiveness. The biggest reason is that the low rate and competitiveness have weakened despite the fact that it has many strengths and scales compared to the major ports due to the small and large number of operating systems through the reckless development of the North and New Ports. While the author works in the operation team of the shipping company and manages the ships coming to the Busan container terminals, a lot of vessel focuses on specific terminals, make a berth congestion each terminal and make unnecessary loss due to the difference in the congestion level of each terminal. Therefore, this paper studied ways to prevent these losses and maximize the efficiency and profitability of Busan container terminal. To do this, large-scale consolidation of operators can lead to reduced competition among operators, cost-efficiency, sales force rationalization and inducement of supplier advantage. This paper is to identify the type and operation status of Busan container terminal operators and to derive the optimal operator model to identify and supplement problems through SWOT and management analysis. This study presents two models, Model A, which integrates HPNT and BNCT, New Port 2-4 terminal, and PNIT, Model B, which integrates BPT and DPCT, and HJNC and Part 2 of New Port 2 after securing new port 2-5 terminal operation rights. And after the completion of the consolidation, the operator presented a reasonable consolidation scenario that operators could change each other's terminals. In addition, it suggested that public and private joint procurement is the best in terms of cost and efficiency as a funding plan for terminal development and integration.
