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 - YNA=0.0002XHA−3.67 , Group B - YNB=0.0002XHB−6.82 , Group C - YNC=0.0001XHC+9.02 . This study contributes to a review of anchorage volume from the perspective of harbor development.
