Offshore wind energy resources are not fully exploited renewable energy resources until now and could play a crucial role in mitigating the impacts of climate change by the generation of renewable electricity. Planning processes such as technical, social, environmental, various agents, and political concerns are necessary for the development of offshore wind energy projects. The objective of this study was to assess the comprehensive feasibility of a desired offshore wind power plant applying Geographical Information Systems (GIS) and Multi-Criteria Decision-Making (MCDM) guidance for the coastal area of Turkey. Furthermore, EMODnet (the European Marine Observation and Data Network) was employed for data acquisition to unlock fragmented and hidden marine data resources and to facilitate investment in sustainable coastal and offshore activities. For the determination of potential site with Multi-Criteria Decision Maker Method, 3 main criteria Technical (C1), Environmental (C2), and Social (C3), and 13 sub-criteria were determined. Based on these criteria, the suitability map was created by using all criteria map layers with their buffer zones. The final map indicated that %1.38 (3294.8 km²) of Turkey Seas was suitable for offshore wind farms. The most suitable region was determined in the Marmara Sea with 1194 km². The Aegean Sea, the Black Sea, and the Mediterranean Sea were following the Marmara Sea in terms of the huge suitable regions respectively. It was apparent that the growth of offshore wind farms in Turkey would increase if the supporting mechanism and the necessary legislation were ensured.

海上风能资源直到现在还没有得到充分利用的可再生能源，可以通过可再生电力的产生在减轻气候变化的影响方面发挥关键作用。技术、社会、环境、各种代理和政治问题等规划过程对于海上风能项目的开发是必要的。本研究的目的是评估在土耳其沿海地区应用地理信息系统 (GIS) 和多标准决策 (MCDM) 指导的理想海上风力发电厂的综合可行性。此外，EMODnet（欧洲海洋观测和数据网络）被用于数据采集，以解锁分散和隐藏的海洋数据资源，并促进对可持续沿海和近海活动的投资。为了使用多标准决策者方法确定潜在场地，确定了 3 个主要标准技术 (C1)、环境 (C2) 和社会 (C3)，以及 13 个子标准。根据这些标准，通过使用所有标准地图图层及其缓冲区来创建适宜性地图。最终地图表明 %1.38 (3294.8 km² ) 土耳其海适用于海上风电场。最适宜的区域是马尔马拉海，面积为1194 km ²。爱琴海、黑海和地中海分别在巨大的适宜区域上紧随马尔马拉海之后。很明显，如果支持机制和必要的立法得到保证，土耳其海上风电场的增长将会增加。
