Thus, the higher the capital costs of the ship, the lower the occupancy rate of berths to avoid the possibility of the arrival of a ship that does not have a berth available at the time of arrival, and thusincrease the cost of waiting for container ships compared to other ships.In general, all ports cannot be occupied by ships throughout the year, because there are certain conditions that differ from the port of one country to the port of another country and even within the same state, and for the same port from time to time. The most important of these factors are:
