The Port of Oakland is currently undertaking a major deepening and seismic upgrade program for the majority of its container cargo berths. It is important for the seismic upgrade of these berths to enable the Port to maintain an acceptable level of container cargo handling operation after an earthquake. This paper describes how acceptable risk evaluation of this system of berths is being used to guide the Port's selection of a seismic upgrade alternative for each berth that best meets this objective. The paper also discusses key issues related to two main elements of the procedure -- the modeling of the seismic vulnerability of the individual WESP berths, and the modeling of how earthquake damage could impact shipping operations throughout the entire berth system.
