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.
