Abstarct: These days wind energy has become one of the most pupolar field for researchers among different types of renewable enrgy. There has been many researches conducted in the field of onshore wind energy. Although offshore wind has been the subject of many investigations worldwide there is still a huge gap in the subject among academic works in Iran, therefore it was the main field of this thesis both to fulfill the gap and become a start point of further work. Due to numerous oil and gas platforms in the southern waters of Iran, this research focuses on the Persian Gulf and Oman Sea as area of research. To achieve the goal of this research, first of all wind data was collected from ECWMF website as a reliable databaxse of meteorogical data. The data was then processed, organized and studied. The result was average annual wind speed for thee zone of study. The suggested area for construction of a wind farm had the coordinate of 27-28 in latitude and 50-52 in longitude, somewhere around Bandar Kangan and Bandar Dayyer. After determining of suitable area, all types of offshore fixed substructures that are used in offshore wind industry was studied and pros and cons was listed. As a conclusion it can be said that the most applicable and adequate one was jacket substructure according to water depth of around 50 meters in selected areas. In the end layout of a wind farm was presented using Jensen method considering wind speed and omitting complicated parameters such as electricity network of the farm and change of wind direction.
