Many of port facilities in Japan were constructed in 1960s, so most of them will be renewed or repaired in 10-20 years. To carry out these renewals and repairs with budgetary limit, reduction of life-cycle cost and/or extension of life for each of these facilities shall be required. Therefore the preventive approach is to be put into the manner of maintenance for port facilities.
Ministry of Land, Infrastructure and Transport updated the ordinance on the technical standards for port and harbour facilities in Japan in 2007. The updated ordinance requires that owners of port facilities shall establish a maintenance plan for each of them, and manage it adaptively according to the plan.
This report shows the analytical procedure of life-cycle cost for port facilities. Parametric study of this analytical method is carried out to provide the effect of preventive maintenance on life cycle cost for each part of each facility. Based on the result of this parametric study, the effect on whole life-cycle cost for port facilities is also discussed.
