Executive Summary

While almost all port and harbor facilities are designed to be in service for a period of 50 years or longer, it is not easy to maintain the required serviceability of the facilities such a long period of time under severe environments. Therefore, a maintenance plan should be prepared in advance so as to satisfy the performance requirements of the facilities during the service period. To ensure efficient and rational maintenance based on the life cycle management (LCM) concept, a appropriate maintenance strategy should be explicitly selected for constituent members at initial design stage. If a facility does not have sufficient durability in its design or construction, it is necessary to apply a high level of maintenance, resulting in increased maintenance cost. In order to achieve strategic maintenance based on the LCM concept, a maintenance plan should be formulated considering the appropriate maintenance strategies. 3 types of maintenance strategies are defined in the “Technical Standard and Commentaries for Port and Harbour Facilities in Japan” published in 2007. In this study, a method to reflect the selected maintenance strategies into structural design was proposed for piers.
