| Abstract |
| Because of climate change, damage to coastal and island regions due to abnormal weather patterns such as drought and typhoons has become a more severe threat. In particular, there is a high risk of water shortages on islands that import water from the mainland by ship because of a lack of a water supply system and groundwater. In addition, ship-based water transport systems have not been well-planned; thus, they involve many simple round-trip operations between the mainland and individual islands, which raises costs. In this study, we attempted to reduce the operating costs of water supply shipments by analyzing water usage on islands and planning a new method of operation. To achieve this, the water supply system is modeled using the GoldSim program, widely employed for water resource and management analysis. The applicability of a shipboard seawater desalination plant was also evaluated. Three different scenario models were analyzed for the applying shipboard seawater desalination plant to island regions. When calculating the minimum travel distance to ensure a stable water supply, it was found that using a shipboard seawater desalination plant minimized the operating space. Because the traveling length of a ship is directly related to costs, the results of this analysis are expected to have economic benefits for water supply systems. |
