Affected by Typhoon "Doksuri", the Beijing and Hebei regions in China experienced their most severe rainfall in nearly a century, resulting in serious flooding across many areas. DEEPINFAR deployed to the disaster zones to assist in the rescue operations.

After arriving at the site and coordinating with local disaster relief authorities, DEEPINFAR started to research the disaster area. Due to heavy rainfall at the site, after completing search and rescue in shallow waters, the team started to search more challenging fast-flowing deep water areas. Given the conditions, it was decided to deploy the Hetun IV-A as a rescue assistant in these deep waters. The Hetun IV-A, compact in size, requires only a small speedboat and two operators for rapid deployment. Equipped with four thrusters, it maintains stability and efficiency in deep water. Additionally, with its sonar and 4K high-definition camera, it ensures effective search capabilities even in complex underwater environments. During the flood disaster, the Hetun IV-A demonstrated strong underwater maneuverability and search and rescue capabilities, reducing the workload for rescue personnel and providing robust support for the rescue operation.
