【Ten Years of Rapid Development in Chemical Equipment】1033-2023: China’s First Integrated Project Combining Offshore Wind Power, Marine Aquaculture, and Seawater Hydrogen Production
Thread Content
Ten years of rapid development in chemical engineering technology; praise for the prosperous and strong China. This is just a starting point to encourage more people to participate and contribute to the discussions. HaiChuan becomes even better with your involvement – we welcome everyone to join in the forum discussions. Be careful with fire risks as the heat increases in July. ---------------------------------------------- On July 10, 2023, the last three sets of equipment for Phase 42 of the Qingzhou project, manufactured by Nantong CIMC Pacific Offshore Engineering Co., Ltd., a subsidiary of CIMC Enrico (hereinafter referred to as “CIMC Pacific Offshore”), were successfully delivered at the Ouhua facility of Zhoushan CIMC Wind Power Equipment Co., Ltd. This delivery marks the completion of all shipments related to the 12 jacket structures for the Qingzhou 42 offshore wind project, which were undertaken by CIMC Pacific Offshore Engineering. The last jacket structure, which is an integrated unit combining a wind turbine foundation developed by MingYang Smart Energy with a fish farming cage, is the world’s first such integrated device for wind energy and fish farming. It is expected to be put into use by late July at the MingYang Yangjiang Qingzhou 4 offshore wind farm project – China’s first project that integrates offshore wind power, marine aquaculture, and seawater hydrogen production. “The integrated equipment of \"wind turbine foundation jacket + fish cage\" uses the wind turbine jacket as its support platform. Although its height is the same as that of a conventional jacket, its weight is more than 200 tons higher than that of a conventional jacket. Equipped with a high-performance net system and an intelligent aquaculture system, it forms an intelligent integrated device that combines offshore wind power generation with deep-sea aquaculture. This approach can effectively improve the efficiency and sustainability of resource utilization in marine areas, reduce the costs associated with resource exploitation, and increase the overall profitability of such projects. The aquaculture water volume is approximately 5,000 cubic meters, allowing for the cultivation of around 150,000 fish. Once the equipment is in operation, high-quality fish species such as groupers will be raised there, with an annual catch expected to reach 75 tons once production begins.
In terms of technology, to cope with the harsh sea conditions in deep-sea areas, this equipment features a typhoon-resistant design that can withstand typhoons of level 16, ensuring the safety and reliability of wind power generation as well as deep-sea aquaculture, and enabling the seamless integration of offshore wind power and marine farms. At the same time, thanks to the use of an intelligent fish farming system, this equipment features functions such as intelligent feeding, intelligent monitoring, automatic net cleaning, and automatic fish harvesting. It addresses the issue of unattended and unsupervised fishing in deep-sea areas, offering new approaches for the exploitation of deep-sea marine resources. During the construction of the project, this equipment faced numerous challenges across various aspects, ranging from thick and medium plate welding, precision control in high-altitude work, welding of mesh components, design of the fish feeding system, and shipping via palletized transport, to project management, procurement, quality control, and production. Due to the excessive weight of the upper structure, which exceeded the lifting capacity of a single crane, the project team decided to adopt a construction method using heavier crawler cranes after optimizing the production processes. This approach ensured the successful delivery of the jacket, earning high recognition and praise from the client. This once again demonstrates the spirit of perseverance and teamwork among the employees of CIMC Pacific Offshore, as well as their ability to overcome challenges; it also serves as strong evidence of the company’s strong capabilities in the construction of offshore wind power infrastructure.
Utilizing the land in salt pans along coastal areas for photovoltaic power generation represents another approach: generating electricity on the water’s surface, producing salt there as well, and engaging in aquaculture underwater. The electricity generated can be supplied to chlor-alkali industries; it’s an excellent green energy solution.
