Core Viewpoint - Offshore wind power has become a highly sought-after renewable energy source in the context of global energy tightening and dual pressures of energy conservation and emission reduction. China is shifting its focus from land-based wind farms to offshore projects due to land resource occupation and noise issues [2]. Group 1: Project Overview - The Fangchenggang offshore wind power demonstration project, located 16 kilometers from the coast, features 83 wind turbines across nearly 100 square kilometers of sea [4]. - This project is the first offshore wind power initiative in Guangxi, marking the beginning of offshore wind power construction in the region [4]. Group 2: Construction Challenges - The construction of offshore wind farms is a complex engineering task that involves underwater piling, installation of towers, turbines, and blades, and connecting them to the onshore grid via underwater cables [5]. - The project faces significant challenges due to the hard rock seabed, requiring all foundations to be embedded rock structures, making it the world's first offshore wind project to use entirely embedded rock guide frames [10][12]. Group 3: Installation Process - The installation of the guide frame was particularly challenging, requiring precise vertical and horizontal alignment, with the installation occurring underwater, making it difficult to monitor [16]. - The installation faced delays due to unexpected difficulties, including the impact of Typhoon "Tali," which affected construction precision [20]. Group 4: Milestones Achieved - On August 13, 2023, after overcoming various challenges, the guide frame was successfully installed, providing valuable experience for future construction [21]. - The first tower section was successfully installed on August 16, 2023, with a maximum diameter of 7.5 meters and a height equivalent to over 30 stories [23]. - The final blade installation was completed on August 19, 2023, marking the successful assembly of Guangxi's first offshore wind turbine [29].
