This paper presents a development of the desalination plant based on the concept of the Wind Energy Marine Unit (WEMU) which is the high-capacity offshore wind turbine with the floating rotor. The great potential and the necessity in seawater desalination for many coastal areas by offshore wind turbines are shown. The design of the desalination plant is described. The plant has a high pressure pump as the first energy converter. Flash evaporation by spraying of the superheated water into the low pressure chamber with subsequent condensation is the core process. Heat exchangers are used for energy recovery. Public meaning, social and economic prerequisites for water desalination by WEMU plants are specified. CFD-methods with a discrete phase model are proposed to simulate the heat and mass transfer in the evaporator. Relations are presented for estimation of the average desalination ratio. It can be about 50 percent.
