Preliminary Design of a Drinking-water Carrier for Water Supply to the Croatian Islands

An analysis of drinking water supply to the Croatian islands indicates an unsatisfactory situation with drinking water on inhabited and occasionally inhabited islands, as well as frequent shortages of drinking water. Besides the fact that this constitutes an obstacle to the economic development of the islands, the scarcity of drinking water further complicates the everyday life of islanders, especially during the summer months when scarcities are more frequent. A particular problem has been observed on islands where the drinking water is supplied by drinking-water carriers. There are four such ships in Croatia, with an average age of over sixty years, which often fail to meet the island’s drinking water demands on time and in sufficient quantity. For strategic reasons, the renovation and strengthening of the Croatian fleet of drinking-water carriers should be definitely considered in order to ensure a secure long-term supply of drinking water to the islands. In the paper a preliminary design of a drinking-water carrier suitable to supply water to the Croatian islands is presented.
