Abstract

This study discusses the influence of various conditions on the optimum maintenance level of composite breakwaters and breakwaters covered with wave dissipating concrete blocks in view of minimum life cycle cost. As the results, it was found that optimum maintenance level depends on wave stability of breakwater, rather than wave condition and loss cost condition. This method can be effectively used for planning maintenance strategy to estimate expected repairing costs of breakwaters.
