全球首个“海风直连”海底数据中心在沪投产

Core Insights - The world's first "offshore wind direct connection" underwater data center has recently commenced operations in Shanghai, marking a significant breakthrough in the integration of artificial intelligence infrastructure, marine energy utilization, and marine engineering in China [1][2] Investment and Project Details - The total investment for the underwater data center project is 1.6 billion RMB, with a total construction scale of 24 megawatts planned in two phases. The first phase, which has been launched, has a construction scale of 2.3 megawatts [1] - The main structure of the offshore platform stands 32 meters tall and weighs 1,950 tons. The core data warehouse is located within a cylindrical vertical structure that is directly submerged in the sea [1] Technological Innovations - The project employs a new structural design for the underwater data center, integrating four core components: upper modules, a guide frame, a data chamber, and steel pipe piles, which enhances overall stability against waves [2] - The data chamber features an innovative cylindrical vertical structure that increases usable space internally and reduces wave impact externally, significantly improving structural stability in turbulent conditions [2] Energy Efficiency - The underwater data center operates on principles of offshore wind direct connection and collaborative energy sharing, making it more energy-efficient compared to traditional data centers. It reduces cooling costs from 40% of electricity expenses to below 10% [1] - The data center is directly connected to the Lingang offshore wind farm, utilizing a photonic electric composite cable to minimize transmission losses, achieving a green electricity supply rate exceeding 95% [1]
