Overcome by the increasing energy demands nowadays and the limited traditional resources, the foremost objective of the proposed study is to evaluate the efficiency of a floating wind farm operating in the coastal environment of the western Black Sea. Since coastal erosion has become a matter of urgent concern during the last decades and many states in the EU (European Union) consider the issue of coastal protection to be of utmost national importance, this study aims to reveal the positive effects such project might provide to the coastal area of Romania. Due to significant decrease of sediments from the Danube basin to the coast in the north along with the extensive development of tourist resorts, especially in the southern part, the erosion process has become more explicit, posing a severe threat primarily on the population living within an area of tens of kilometres from the coast. To provide a better overview of the principal wave patterns in the targeted area, the ERA5 dataset has been considered for the evaluation of the wave power for the 40-year period (1979–2018) for two reference points located in the proximity of the target area. Four scenarios for the simulations were carried out with a computational structure that combines a circulation model with a wave model. A generic wind farm was defined in the computational domain, taking into consideration steadily increasing distances from the shoreline: 4, 6 and 8 km. Firstly, taking into account the local wave patterns, and three-wave parameters — the significant wave height, the mean wave height and direction, the down-wave effect of the farm was evaluated. Secondly, the influence of the generic farm on the longshore currents was also assessed. The concluding results suggest that if such a project is to be taken into consideration, it would not only provide valuable renewable energy, but it would also guarantee adequate coastal protection by reducing the impact of waves and intensify resilience to terrible weather.

克服当今日益增长的能源需求和有限的传统资源，拟议研究的首要目标是评估在黑海西部沿海环境中运行的浮动风电场的效率。由于海岸侵蚀在过去几十年中已成为一个紧迫的问题，并且欧盟（欧盟）的许多国家都认为海岸保护问题对国家至关重要，因此本研究旨在揭示此类项目可能对国家产生的积极影响。罗马尼亚沿海地区。由于北部多瑙河盆地沉积物显着减少，随着旅游胜地的广泛开发，特别是南部，侵蚀过程更加明显，主要对居住在距海岸数十公里范围内的人口构成严重威胁。为了更好地概述目标区域的主要波浪模式，已考虑将 ERA5 数据集用于评估位于目标附近的两个参考点的 40 年期间（1979-2018）的波浪功率区域。模拟的四种场景是通过将环流模型与波浪模型相结合的计算结构进行的。在计算域中定义了一个通用风电场，考虑到与海岸线的距离不断增加：4、6 和 8 公里。首先，考虑到当地的波浪模式和三波参数——有效波高、平均波高和方向，评估了农场的下波效应。其次，还评估了普通养殖场对沿岸洋流的影响。结论结果表明，如果考虑这样一个项目，它不仅可以提供宝贵的可再生能源，而且还可以通过减少波浪的影响和加强对恶劣天气的抵御能力来保证充分的海岸保护。
