“蓝海绿算”！全球首个“海风直联”海底数据中心在沪启用

Core Viewpoint - The world's first underwater data center utilizing "offshore wind direct connection" technology has officially commenced operations in Shanghai Lingang, marking a significant breakthrough in the integration of artificial intelligence infrastructure, marine energy utilization, and marine engineering in China [1][3]. Investment and Project Overview - The total investment for the Shanghai Lingang underwater data center project is 1.6 billion yuan, with a total construction scale of 24 megawatts planned in two phases. The first phase, now operational, has a construction scale of 2.3 megawatts [3]. - The project innovatively combines "offshore wind power direct connection" and "natural seawater cooling" technologies, achieving a PUE (Power Usage Effectiveness) of no more than 1.15 and a green electricity supply rate exceeding 95% [3]. Design and Engineering Innovations - This underwater data center is the first of its kind to integrate "offshore wind power direct connection" and "natural seawater cooling" technologies, facing complex marine conditions that traditional designs cannot accommodate [4]. - The design team has created a new structural model for the underwater data center, utilizing a "cylindrical vertical structure" for the data cabin, which enhances internal usable space and reduces wave impact, significantly improving overall stability [6]. Construction and Installation Achievements - The construction team employed innovative welding techniques, achieving a one-time pass rate of 98.6% during the welding of the conduit frame, demonstrating high precision and quality control [8]. - The installation process involved a complex underwater operation, where the data cabin was successfully submerged and precisely aligned with the underwater steel piles, achieving "zero deviation" during the critical installation phase [11].
