Abstract

The main purpose of this study is the economic study of the use of fixed and floating freshwater in Makran beaches. One of the most important methods in this field is the desalination and desalination processes of seawater. Given that for government projects only the final price or in other words the cost price is considered, the method of uniform value of costs over the useful life has been chosen.

According to the information of the Electricity and Energy Master Planning Office of the Ministry of Energy, the results show that desalination of sea water in the form of building a factory (fixed desalination plant) is more economical compared to the floating desalination plant, in such a way that the cost The production uniformity in fixed desalination technology is 2000 and in floating desalination technology is 9700 rials per cubic meter.

Also, sensitivity analysis tests based on discount rate, production capacity coefficient and escalation rate of fuel cost show that on one hand, floating desalination technology is more sensitive to the above variables than fixed desalination, and on the other hand, the change of this variable has no effect on changing the economic priority.

The results show that seawater desalination in the form of a factory (fixed desalination) is economical compared to floating desalination.
