Probabilistic Seismic Direct Loss Estimation for Ports, Case study: Pars Asaluyeh port

Ports are the main avenue of global freight transport. In the past, experience has shown that ports are vulnerable to earthquakes, which cause evident economic damage. The port at Kobe, Japan, experienced economic losses of about $11 billion after an earthquake in 1995. The present study used the full-probabilistic PEER-PBEE framework to develop a comprehensive seismic risk assessment approach with which to estimate the total direct and indirect economic loss incurred by a port experiencing an earthquake. In the proposed methodology, the extent of direct economic loss due to the cost of repair of port structures in the Pars Asaluyeh port was estimated. Seismic risk density curves (SRDCs) were employed to determine the seismic performance of different port structures and pieces of equipment as well as the overall seismic performance of the port. The SRDCs show that the mooring structures and breakwater of the port showed appropriate seismic performance, while other port structures and equipment showed weak or average seismic performance.
