Deepinfar is proud to have served as the underwater monitoring and assurance technology partner in the successful installation of China’s largest cross-section and longest single-span inland immersed tunnel.
During the installation, Jiangtun IV-C played a critical role by:
Monitoring guide frame positioning in real-time via sonar
Using depth sensors to assess vertical differences between pipe and platform
Supporting decision-making with accurate data for safe and precise placement

With high-definition cameras and imaging sonar, the ROV also collected structural and terrain data to power the project's digital twin monitoring system — enabling visualized and data-driven management throughout the operation.

This approach significantly reduced diver workload in confined spaces
Improved efficiency and enhanced the safety and quality of the underwater construction

Deepinfar remains committed to empowering critical infrastructure projects with smart, reliable underwater technology.
