This study suggests design criteria to evaluate the availability of anchorage in Korea to contribute to ship safety by presenting necessary design criteria for anchorage volume according to port development. Accordingly, the concept of "necessary volume of anchorage" is introduced to evaluate the volume of anchorage available in Korea's major ports, and classify these ports into three types according to the characteristics of incoming ship. Numerical simulations designed using MATLAB-SIMULINK have been carried out to track the irregularly of arrival and, waiting times along with the environmental conditions that affect anchorage and necessary volume of anchorage have been suggested based on these tests. Finally, in order to complete a function equation analysis, the necessary volume of anchorage with reference to cargo volume is addressed using regression analysis as follows. Group $A-Y_{NA}=0.0002X_{HA}-3.67$, Group $B-Y_{NB}=0.0002X_{HB}-6.82$, Group $C-Y_{NC}=0.0001X_{HC}+9.02$. This study contributes to a review of anchorage volume from the perspective of harbor development.

Relocation and expansion of existing port facilities are necessary given this increase in marine traffic volume and the presence of larger entering vessels. Therefore, this study focused on anchorage among water facilities, and examined the degree of harmony between anchorage and other water facilities at Yeosu Kwangyang Port. The number of anchoring vessels in relation to anchorage over the past 5 years, total anchored hours by anchorage-years, average number of simultaneously anchored vessels by anchorage-years, maximum number of simultaneously anchored vessels by anchorage, and maximum size of anchored vessels by anchorage have been surveyed. The minimum anchorage radius has been calculated according to the designated anchorage capacity according to anchorage. Finally, improvement plans for Yeosu Kwangyang Port's anchorage have been suggested, including relocating of Yeosu no. 2 anchorage, expanding of Kwangyang no. 1 ~ 5 anchorage, relocating of Kwangyang no. 8 ~ 9 anchorage, and repealing of Kwangyang no. 11 anchorage.
