Abstract

Ports exposed to high energy long wave conditions can experience significantly reduced berth availability, leading to loss of throughput. The Port of Geraldton, located in Western Australia, is an example of such a port. A range of alternatives to mitigate the long wave energy problem at this port have been examined, but each varies significantly in terms of both operational benefit and economic impact. The most technically effective solution may not necessarily yield the largest economic return. In this paper, a discrete event simulation model of port operations is used to assess the cost and benefits of various long wave mitigation approaches. The results showed that mooring configurations involving the use of port-supplied nylon breast lines held under high pre-tension by means of brake winches on the wharf appear to provide among the most favourable economic return for the Port of Geraldton. More effective ship response performance can be achieved through use of pneumatic fenders and shore-based constant tension winches, but at higher cost and slightly less favourable economics. Extending the existing port breakwater provided the least economic return due to its high cost and limited impact on berth long wave energy in the appropriate frequency range. View Full-Text
