Recently, great news came from the practical waters rescue training site for firefighters in the Han River waters of Seoul, South Korea – the "Underwater Communication and Navigation System," independently developed by Ocean Plan, completed its advanced training. The system's powerful underwater communication and positioning capabilities ensured real-time coordination between surface command and underwater operations in complex waters, efficiently enhancing collaborative water rescue capabilities and earning high recognition from local professional firefighters.
Training Base of the Seoul Fire and Rescue Brigade
Why do Seoul firefighters regard the Han River as the core site for underwater rescue training? This iconic river, which witnessed the "Miracle on the Han River," is actually also a rare natural "underwater testing ground" globally, presenting unprecedented challenges for various types of water emergency response technologies.
Extremely Complex Environment: The Han River channel is over 1 kilometer wide, with underwater visibility approaching zero. At an average depth of around 10 meters, multiple undercurrents lurk, and water flow velocity fluctuates drastically with terrain changes.
Prominent Communication Challenges: Traditional underwater communication is severely affected by acoustic wave attenuation and multipath propagation interference. Under such hydrological conditions, the command end and divers often fall into a "communication blackout dilemma," which is a common challenge in global water rescue.
Urgent Task Demands: As a lifeline waterway traversing Seoul, the Han River requires response to a large number of drowning accidents, shipwreck salvage, and special emergency tasks annually. Among these, "Mapo Bridge" has become a key prevention area due to frequent jumping incidents, creating a rigid demand for efficient and safe collaborative rescue technologies.
Solving the Challenge of Underwater Cluster Collaboration
Facing the complex hydrological environment of the Han River, Korean firefighters in the practical training focused on utilizing the system's two core networking modes, fully leveraging their practical value in diverse scenarios.
Surface-Underwater Joint Networking: Enabling "Transparent" Command
Through this networking mode, surface command personnel can obtain real-time data on underwater divers' location dynamics, task progress, and status information. This capability of "complete situational awareness and instant command delivery" multiplies the decision-making efficiency for complex rescue tasks and provides stronger safety assurance for the entire team.
Independent Underwater Diver Networking: Building a "Safety Community"
In waters with complex underwater structures, a designated dive team leader initiates the formation of an independent underwater wireless network. Without relying on surface signal support or deploying any surface equipment, divers achieve real-time interconnection through the Dive Navigation Computer, enabling real-time communication and location sharing.
Multi-Scenario Empowerment Beyond Rescue
The Underwater Communication and Navigation System, which shone in this water rescue training, is actually an "integrated underwater solution" incorporating multiple core technologies. Its core functions comprehensively cover emergency response needs.
Underwater Positioning & Navigation
Accurately tracks personnel location and supports rapid marking of target areas.
Underwater Wireless Communication
Achieves "full water area" network coverage, enabling voice and text interconnection.
Diver Physiological Monitoring
Perceives data "cross-medium," providing real-time monitoring of core physiological indicators.
Underwater Cluster Networking
Flexibly establishes operation networks, ensuring efficient multi-task collaboration.
Abnormal Status Alert
Monitors motion status throughout, with immediate warning and response to abnormal situations.
The "China Solution" for Underwater Safety
The rescue application of the "Underwater Communication and Navigation System" in the Han River is not just the application expansion of a single product; it highlights the "generational" breakthrough in China's underwater communication and positioning technology:
Breaking Monopolies, Achieving Independence and Control
Successfully broke through foreign technological barriers in the high-end underwater equipment field, mastering core independent intellectual property rights for underwater communication and underwater positioning.
Equipment Innovation, Driving Individual Soldier Evolution
Ultra-compact, highly integrated individual underwater communication and positioning equipment significantly enhances the mobility and operational efficiency of underwater personnel.
Pioneering Functions, Setting Technical Benchmarks
Self-developed core technologies such as "Diver Physiological Monitoring" and "Independent Underwater Networking" are globally "leapfrogging" innovations.
Broad Applicability, Demonstrating Systemic Advantages
The system can calmly handle various complex water environments, ensuring mission success with excellent scenario adaptability and practical stability.
From the Han River training ground to global application fields, the Underwater Communication and Navigation System is reshaping the safety boundaries of underwater operations. When technology builds an invisible "bridge of life" underwater, every precise rescue gains more confidence, and every diver gains an extra layer of protection.
Ocean Plan will remain true to its founding mission, consistently practicing the purpose of "For Life and Exploration," and assisting global water rescue capabilities to reach new heights.
