China’s Jiaolong Submersible Descends 7 Kilometers, Testing AI for Seafloor Exploration

Diving Seven Kilometers Deep

According to НВ — Техно: The Chinese deep-sea vehicle Jiaolong recently completed a dive in the Pacific Ocean, reaching a depth of 7,056.9 meters within the Philippine Trench. During this mission, advanced artificial intelligence systems were tested to diagnose and analyze the seafloor. These innovations are also being considered for use on nuclear submarines. The details emerged from Chinese media on October 31 at 13:50 and were later reported by Interesting Engineering.

Cutting-Edge Technology and Capabilities

The dive validated the reliability of upgraded equipment, incorporating Chinese-made components for key systems. Jiaolong’s AI framework is designed to detect malfunctions in critical hardware, including propulsion and control systems. It provides step-by-step troubleshooting guidance, access to previous failure records, and technical documentation to assist in repairs. This technology has potential applications in speeding up fault detection and risk assessment on nuclear-powered submarines.

Additionally, Jiaolong was equipped with a multimodal large AI model specialized in seafloor research. Trained on over 800,000 images of deep-sea organisms and sediment types, this AI analyzes video feeds in real time, recording objects along with their coordinates, timestamps, and depths. It supports manual correction of recognition errors to refine the model continuously. The system can interact with operators through dialogue, reconstruct dive trajectories in 3D, and generate detailed reports on benthic ecosystems.

• These AI techniques can be adapted for sonar data analysis on submarines.
• The AI is capable of distinguishing different sources of underwater noise and flagging unusual signals.

Currently, Jiaolong’s AI works exclusively with visual data, but future upgrades may significantly enhance deep-water research capabilities.

The Jiaolong dive and its AI innovations highlight China’s expanding commitment to exploring the ocean’s depths.

Employing AI in underwater exploration not only advances our understanding of marine ecosystems but also improves the operational efficiency of submersibles, including nuclear submarines. This development underscores the growing role of modern technologies in scientific and military maritime endeavors, with far-reaching implications for oceanography and naval security.

As the field of underwater exploration advances, innovations like the latest underwater robot inspired by marine life demonstrate the growing intersection of technology and environmental research. These developments highlight the potential for enhanced silent monitoring of deep-sea ecosystems, complementing the capabilities showcased by Jiaolong's recent dive.
