The port of Los Angeles is primarily used by large container ships that transport goods from Asia. These goods are then shipped through trucks to various parts of the country. Regulations allow ships to dock at the port only between 6 am and 6 pm. On average, one ship docks at the port every hour during the working hours (thus, the average number of ships docking in a day is 12) and carries 1000 containers. The process flow at the port consists of two main steps described below. Unloading: Cranes unload containers from a ship and store them in a warehouse. On average, it takes a crane 3 minutes to unload a container. There are 50 cranes that work in parallel. The unloading step also operates for only 12 hours a day, from 6 am - 6 pm. Loading: The containers in the warehouse are then placed onto trucks which carry them to various destinations across the US. The warehouse has 100 gates that operate parallelly, and each gate can be used to load one truck at a time. Each truck can only carry one container, and it takes 12 minutes to load a container onto a truck. Unlike the unloading process, the loading process can operate 24 hours a day. The transported goods are always in high demand and trucks are always available. Unloading From Asia from ships Loading onto trucks Domestic Destinations 17.
