The island province of Hainan in southern China has long been associated with gorgeous sandy beaches and duty-free shopping malls. However, China has launched the world’s first commercial underwater data center. Its coastal waters now house a fantastic innovation: a “smart brain” in the sea. This groundbreaking achievement represents a considerable step forward in China’s efforts to exploit marine resources for superior computing power.

A Technological Marvel Beneath the Waves

About a month ago, a crane ship delicately lowered an 18-meter-long and 3.6-meter-wide white cylindrical data module into the ocean. It dropped to a depth of 30 meters at Lingshui Li Autonomous County and became an essential component of the world’s first commercial underwater intelligent computer cluster.

This cutting-edge module houses over 400 high-performance servers and connects to an existing undersea data centre, which was first deployed in March 2023. With this update, the Lingshui project achieves a groundbreaking processing capability equivalent to 30,000 high-end gaming PCs running concurrently. The centre’s massive processing power allows it to accomplish in one second what a typical computer would take an entire year to do.

Transforming AI and Industry Applications

The high-performance computing (HPC) cluster supports various artificial intelligence (AI) applications, including DeepSeek, which can manage around 7,000 intelligent interactions per second. According to Pu Ding, the general manager of the Hainan undersea data centre demonstration project, the facility has already signed contracts with approximately ten companies from various industries.

China has launched the world’s first commercial underwater data center, and the underwater computing hub is poised to revolutionise various industries, including:

• Artificial Intelligence (AI): Cutting AI model training time from months to weeks, increasing innovation in deep learning and machine learning applications.
• Gaming: Enabling complicated rendering processes and maintaining robust multiplayer operations for next-generation gaming experiences.
• Industrial Simulation: Enables complex simulations for the engineering and industrial industries, increasing efficiency and accuracy.
• Marine Research: Establishing a reliable computing infrastructure for oceanographic investigations and climate change research.

This endeavour integrates maritime engineering and digital infrastructure, raising critical challenges such as why a computing centre should be built underwater and how this would improve China’s computational capabilities.

A New Frontier in Computing and Sustainability

China has launched the world’s first commercial underwater data center, and this project is more than just a technical achievement; it represents a step towards more sustainable and energy-efficient computing. Pu describes the initiative as a “green, low-carbon, and high-efficiency” invention that matches China’s overall objective of increasing computing power while minimising environmental impact.

China’s aspiration to become a global leader in artificial intelligence and high-performance computing is reflected in its national plan, which was published in October 2023 and intends to boost the country’s total computing power by more than 30% by 2025. By then, China hopes to have a total computer power of 300 EFLOPS (exaflops). To put this in context, 1 EFLOPS is one quintillion floating-point operations per second—a measure of supercomputing power.

While China has been establishing computing hubs in major cities such as Beijing, Shanghai, and Shenzhen, the Hainan underwater project adds a marine component to the technological landscape. This “ocean-digital fusion” complements China’s dual carbon targets of reaching peak emissions by 2030 and becoming carbon neutral by 2060.

Why Consider Computing Underwater?

Heat dissipation is a significant issue for older data centres. These facilities need enormous energy for cooling, resulting in considerable environmental and economic implications. However, the underwater computing centre in Lingshui takes advantage of seawater’s natural cooling qualities. The ocean’s cooler temperatures and high-pressure conditions save energy while reducing the need for freshwater cooling systems.

According to Pu, a single module with a 1MW power supply may deliver 1,400 PFLOPS (petaflops), providing 40% more computational efficiency than traditional land-based data centres. The existing 675 PFLOPS computing cluster is already comparable to medium-sized terrestrial facilities.

A semi-annual report issued by China Telecom Hainan and the China Academy of Information and Communications Technology (CAICT) validated the undersea data centre’s stable performance since its deployment in 2023, with zero server failures and no requirement for on-site maintenance.

A Global First in Commercial Underwater Computing

While Microsoft experimented with an underwater data centre (initiative Natick) in Scotland in 2015, Hainan’s initiative is the first wholly commercialised application of this technology. Pu emphasised the complexities of designing a commercial undersea data centre, which requires standardised, client-driven solutions beyond previous experimental settings.

Another distinguishing aspect of Hainan’s initiative is its adaptability to various marine settings. Unlike Microsoft’s project, which runs in milder waters, the Hainan centre is in one of China’s warmest maritime locations. This demonstrates the technology’s robustness and potential for use in a variety of undersea climates around the world.

Technological Innovations and Future Prospects

The success of the underwater computing cluster is based on numerous revolutionary technological advancements:

• Sealed Modules: Designed to be watertight for five years without requiring maintenance, these modules use dual O-ring seals and ballasted construction to withstand severe ocean currents and storms.
• Cost-Effective Industrial Chain: China’s rich manufacturing ecosystem reduces research and development expenses, allowing for large-scale manufacture of undersea data centres.
• Scalability: The project’s modular design enables future growth and interaction with other marine computing initiatives.

According to Pu, China’s well-established industrial chain and robust foundational infrastructure pave the ground for large-scale commercialisation of undersea data centres.

A Strategic Boost for Hainan’s Digital Economy

Looking ahead, the Lingshui underwater project will help to establish an intelligent computing centre for the Hainan Free Trade Port (FTP). Hainan, one of China’s special economic zones, is expected to become a hub for cross-border data exchanges and AI-driven economic growth. Liu Jinpeng, the director of Lingshui’s Sci-Tech, Industry, and IT Bureau emphasised the importance of computing power as a new strategic resource. By combining high-performance computing with industry applications, the initiative enhances digital capabilities and lays the path for new industrial development models.

A Digital Bridge Connecting China and the World

The underwater data centre in Hainan represents China’s expanding openness in the digital age. The project promotes cooperation with Southeast Asian and Belt and Road Initiative (BRI) member countries, facilitating the spread of Chinese digital services abroad while attracting foreign firms seeking access to China’s technical advancements.

Liu said, “We look forward to building an ecosystem around computing power that positions Hainan and Lingshui as a hub for international exchanges in digital technology.”
