For increasing sufficient revenues, reactivating assets, as well as catering to the needs of the local community, Taiwan International Ports Corporation, Ltd. (TIPC) is planning to build the third harbor of Su-Ao Port as a cargo transport and transit area and a complex and diversified shopping mall. The wharves for bulk cargo handling will reduce with the construction of this tourism and transit area, and the berth occupancy rate will also rise inevitably. Judging from the past 5 years’ data of bulk cargo handling and ship berthing hours in Su-Ao Port and the forecast of the berth occupancy rate with the bulk cargo handling of 6,007,800 tons in 2021 (from the planning report of CECI), this paper aims to analyze and predict berth occupancy rate and ship berthing hours in order to offer strategies and solutions for governments’ reference. The final results show that the ship berthing hours of the third harbor of Su-Ao Port will be estimated 13,646 hours in 2021 and the non-contaminated goods and contaminated goods will be 8,588 hours and 5,058 hours respectively. According to these estimates, we propose a feasible and adjustable alternative in which the berth occupancy rate will reach its ideal values. Meanwhile, we suggest revising operation directions for the ship berthing wharf of Su-Ao Port in accordance with the berthing coordination and the re-planning of the use of the wharf.
