A METHOD FOR SEISMIC RISK ASSESSMENT OF PORT FACILITIES

During recent earthquakes the poor seismic performance of seaports has resulted in billions of dollars of losses. Seaports are critical nodes in regional transportation networks and can have important to the economy of the area. In this paper a general port seismic risk model is developed that provides information on potential direct and indirect economic losses from potential failure of facilities and operations at a port. The model is composed of two independent components: the vulnerability model and the port operations model. The vulnerability model produce a set of post-event damage states for port components, corresponding repair times and direct repair costs. The port operations model is a discreteevent simulation that estimates ship arrivals, waiting times and the number of diverted ships. The output from this model is the expected loss of revenue due to downtime. The model is illustrated through an example application. (A) For the covering abstract see ITRD E121600.
