In the deep waters of Yangjiang River in Guangdong Province, a grand project that integrates blue energy and digital intelligence is quietly taking root. Here, it is not about extracting oil or natural gas, but about nurturing a globally leading digital brain - the Yangjiang GW level underwater computing power center. It lies quietly beneath the sea, cleverly utilizing the low temperature of the ocean and the green power of wind power to inject powerful computing power support into China's dream of becoming a maritime power.

The underwater digital base has been built

Recently, the Yangjiang GW level underwater computing power center was officially launched. This is one of the largest and most technologically advanced underwater computing centers in China, and also the first specialized green computing hub for the marine field in the country. The project is located in the Yangjiang sea area, with a water depth of 46 to 57 meters and stable geological conditions. It is adjacent to a local offshore wind power base with a capacity of tens of millions of kilowatts, with a planned total installed capacity of 2 million kilowatts. It can directly use clean wind power and has successfully created a new model of computing and electricity synergy that combines sea breeze and underwater computing power.

The center is jointly initiated and guided by the China Association of Productivity Promotion Centers and the China Ocean Mineral Resources Research and Development Association, and is jointly built and operated by top units such as China Huadian Group, China Unicom, and China Science and Technology Corporation Shuguang. The project is planned to be implemented in three phases, with a total investment of over 110 billion yuan. After completion, its total power will reach 1.15GW and its computing power scale will exceed 260000 P, making it a leading global marine computing power industry base.

Leading technology and excellent energy efficiency

This underwater computing center has achieved multiple breakthroughs in technology and energy efficiency. It adopts a unique semi submersible cylindrical vertical seabed data cabin integrated design with the offshore platform. The three-layer modular underwater cabin structure is sturdy and can withstand deep-sea high pressure, corrosion, and sealing challenges. A total of 180 high-density cabinets are deployed inside the cabin, with a total IT power of 7080 kilowatts.

Its core technology equipment has been fully localized, equipped with Shuguang liquid cooled GPU servers, distributed storage, and high-speed networks, and constructed a four plane physical separation architecture. The interconnection bandwidth between devices is as high as 400Gbps, and the end-to-end communication delay is less than 1 microsecond, ensuring the ultimate data processing speed.

What is particularly prominent is its green and energy-saving characteristics. By utilizing natural seawater cooling and full chain liquid cooling technology, the energy efficiency value PUE of the center has been reduced to below 1.1, which is more than 30% higher than traditional data centers. It can save over 360 million kWh of electricity annually. Its green electricity usage rate exceeds 95%, making it a benchmark for near zero carbon computing power. At the same time, the operation and maintenance can reuse the existing all-weather guarantee system for offshore wind power, achieving minute level rapid response to faults and significantly reducing operating costs.

Empowering the Future of Blue Economy

As an exclusive intelligent computing center in the marine field, the Yangjiang project will focus on serving marine scientific research and strategic emerging industries. It can support the training of trillion parameter level ocean models, achieve 14 day accurate ocean forecasting, and minute level ocean disaster warning. Its computing power will be widely applied in core scenarios such as high-precision ocean numerical simulation, remote sensing data processing, and deep-sea resource exploration.

In the future, the center will comprehensively serve key industries such as marine new energy development, deep-sea aquaculture, marine biomedicine, and marine aerospace, driving the digital transformation and upgrading of the marine economy. The first year of the project is expected to directly generate revenue of 310 million yuan. Throughout the entire lifecycle, it is expected to drive the aggregation of high-end marine equipment, communication networks, artificial intelligence algorithms, and other industrial chains, driving supporting investment of over 50 billion yuan, and helping to promote Yangjiang to become an innovative highland of marine digital economy in southern China.

The completion and operation of the Yangjiang Underwater Computing Center is a major breakthrough for China in the coordinated development of computing power and electricity, as well as the coordinated development of land and sea. It fills the gap in specialized green computing infrastructure in the marine field, and has important milestone significance for activating blue new quality productivity, ensuring national marine security, and supporting the achievement of dual carbon strategic goals.Editor/Yang Meiling
