Abstract
A port structure is no longer thought to be everlasting but is maintainable with an increasing number of options such as reinforcement and corrosion protection. In Chapter 2, the PW method was applied to the LCM of the port structures that have deteriorated.
The construction, repair, shutdown and demolition costs were used for calculating the PW in the Kamsar port. In Chapter 3, how to calculate the shutdown cost both from the exported ore cost and the demurrage was shown in detail, and the effect of the maintenance cost/total cost ratio to the PW value was investigated.
Because the benefits to the citizenry at planning phase are difficult to estimate with much accuracy, the B/C ratio method is applied to a public sector project instead of the PW method. However, if all the cash flows at construction phase which consist of construction, maintenance and demolition are quantified, the PW method can be applied to the LCM of both private and public sector projects. In Chapter 4, an example of the B/C ratio method’s application and the applicability of the PW method to the LCM of port structures were shown.
