Motivated by soial and environmental reasons, water scarcity has become a global top agenda item. Egypt is one of the countries suffering from an acute shortage of freshwater. A promising novel and efficient solution to overcome Egypt's freshwater shortage, especially in remote coastal areas far from the national grid of freshwater and electricity, is a mobile floating desalination plant (FDP) powered by offshore renewable energy. The proposed new FDP concept powered by an offshore wind turbine needs a special floating platform to provide enough buoyancy to support the weight of the desalination plant and to restrain the six degrees of freedom motions within an acceptable operational limit for a wind turbine. Based on hydrodynamics, the main objective of this study is to select the suitable offshore platform that can meet the novel FDP concept operation's requirements at a specific deployment location in Egypt. Determining the safe natural frequencies zone necessitates taking into account the new FDP concept operation constraints and the Egyptian environmental loads to select platform far from the dynamic amplifications responses in the structure. Numerical modelling results show that the cylindrical platform with a heave plate configuration demonstrated the best dynamic and static performance for Egypt.

由于社会和环境原因，水资源短缺已成为全球头等大事。埃及是遭受严重淡水困扰的国家之一。克服埃及淡水短缺（特别是在远离国家淡水和电力网的偏远沿海地区）的一种有希望的新颖而有效的解决方案是一种由海上可再生能源提供动力的移动式浮式海水淡化厂（FDP）。由海上风力涡轮机提供动力的拟议新FDP概念需要一个特殊的浮动平台，以提供足够的浮力来支撑海水淡化厂的重量，并将六自由度运动限制在风力涡轮机的可接受操作极限内。基于流体动力学，这项研究的主要目的是选择合适的海上平台，以满足埃及特定部署地点的新型FDP概念作战要求。确定安全固有频率区域必须考虑新的FDP概念操作约束和埃及环境负荷，以选择远离结构中动态放大响应的平台。数值模拟结果表明，具有升沉板结构的圆柱平台表现出埃及最佳的动态和静态性能。确定安全固有频率区域必须考虑新的FDP概念操作约束和埃及环境负荷，以选择远离结构中动态放大响应的平台。数值模拟结果表明，具有升沉板结构的圆柱平台表现出埃及最佳的动态和静态性能。确定安全固有频率区域必须考虑新的FDP概念操作约束和埃及环境负荷，以选择远离结构中动态放大响应的平台。数值模拟结果表明，具有升沉板结构的圆柱平台表现出埃及最佳的动态和静态性能。
