The World's First Wind-Powered Underwater Data Center Officially Launched, China Comservice Crafted a Benchmark of Computing Power

27 Oct 2025

On 21 October 2025, the world's first wind-powered underwater data center was officially launched in Lin-gang Special Area in Shanghai, and Shanghai Telecom Engineering Co. Ltd. ("Engineering Company"), a subsidiary of the Shanghai Company under China Communications Services Corporation Limited ("China Comservice", HKSE code: 552), had been involved in the entire construction process of the project.

By innovatively integrating two technologies of direct green power supply from offshore wind and natural seawater cooling, the project realizes collaborated development of offshore green energy and underwater computing power. As a critical computing power infrastructure under Shanghai's strategy of building an "International Digital Hub", the project involves a total investment of RMB1.6 billion, with a planned total capacity of 24 megawatts (MW) to be implemented in two phases. Among which, the Phase I demonstration project involves a capacity of 2.3 MW, with over 95% of green power supply rate. The project strongly aligns with the direction of the upcoming 15th Five-Year Plan, demonstrating significant foresight and serving as a noteworthy benchmark.

As a participant involving in the full-process construction, the Engineering Company has deeply engaged since the project's inception, extending from the planning phase through to the design refinement and implementation. The Company undertook critical tasks such as preliminary drawing refinement, engineering quantity verification, and budget preparation. Based on the actual construction progress of the offshore engineering structures, the project team formulated a detailed electromechanical delivery schedule, providing clear work guidelines for all participating parties, which effectively supported the efficient advancement of subsequent engineering work.

After the project officially commenced on site, the project team confronted multiple construction challenges including high temperatures, high humidity, and confined spaces. Through scientific organization and multi-party coordination, the team fully leveraged on-site conditions to synchronize overlapping construction processes across electrical, HVAC, low-voltage systems, and other specialized processes. All tasks, including complete equipment installation, main cable laying, and server rack mounting were successfully completed before the scheduled deadline, securing valuable time for subsequent offshore installation and making a significant contribution to the project's overall on-schedule delivery.

The completion of the Shanghai Lin-gang Underwater Data Center marks a significant milestone in promoting the integrated development of the digital economy, new energy, and marine economy in the Lin-gang Special Area. It also represents another important initiative by Shanghai in serving national strategies and building a global hub for technological innovation. This project will provide an exemplary model for computing power infrastructure construction in China’s coastal regions and along the Maritime Silk Road. As a New Generation Integrated Smart Service Provider, China Comservice will actively support national strategies of "Digital China" and "Building China into a Strong Maritime Country", contributing wisdom and strength for consolidating the national computing power foundation and empowering the digital transformation of industries across sectors.
