This paper focuses on the coping ability of the existing container terminals when mega containerships call at a port. The length of 30,000 TEU (Twenty Equivalent Unit) ships are predicted to be 453 m and occupy 498 m of a quay wall. As a result, the length of berth should be more than a minimum of 500 m. If a 25,000 TEU ship or 30,000 TEU ship call at a terminal, the outreach of QC (Quay Crane) should be a minimum 74.3 m or 81.0 m respectively. As mega ships are calling at the port, the ship waiting time, the available stacking area, and the number of handling equipment can be limited. The analysis reveals that larger ships wait for longer than the smaller ones because they have difficulty allocating the proper seat on berth. As a result of the survey in a terminal, the average occupancy is shown to be 60.4%, the minimum is 52.4%, and the maximum is 73.3%. Surveying the monthly equipment operation rate for 3 years, the average is 85.8%, the minimum is 80.1%, and the maximum is 90.1%. If a mega ship of more than 25,000 TEU appears, the rate will be excessively increased during peak time. View Full-Text
