Evaluation of the port operation conditions influencing the selection of Berth Occupancy Rates (BOR)

Abstract

This article presents a new approach to evaluate the factors that influence the selection of Berth Occupancy
Rates (BOR) using a simulation method. The berth occupancy rate is a crucial parameter used to determine the number of berths and the operational capacity of a port. Typically, studies, guidelines, and standards suggest that the berth occupancy factor should be based on the pattern of ship arrivals at the port. However, these recommendations often overlook natural conditions and port operational regulations. This paper investigates how port operation conditions (such as waves and water levels) and safety conditions (including safety protocols) affect the determination of the berth occupancy factor and provides a comprehensive analysis of these influences. The research findings are specifically applied to Lach Huyen Port in Hai Phong, offering a representative example for selecting an appropriate berth occupancy factor under varying conditions.
