The Grey Whale G1 from ZIYAN Tech has completed a dynamic offshore delivery mission using an unmanned helicopter to validate the technical feasibility of logistics to moving vessels under real operational conditions.
Mission Profile and Execution
The operation has utilized an unmanned helicopter platform to execute a beyond-visual-line-of-sight transport task from a coastal launch site. Covering a distance of approximately 16 km, the flight has included autonomous navigation and real-time tracking of a moving maritime target. Following dispatch via a digital scheduling platform, the unmanned helicopter has completed a stabilized hover above the vessel and precision payload delivery via an onboard winch system. The total delivery cycle has been finalized within approximately 20 minutes, including a stable return-to-base phase.
Technical Architecture
The platform has integrated high-precision GNSS-based navigation with adaptive flight control algorithms to maintain stability under dynamic maritime conditions. By continuously tracking a moving vessel during the terminal phase, the system has demonstrated its capability for non-static target engagement. This is supported by an electromechanical winch-based delivery mechanism, which has allowed for controlled payload descent without the requirement for landing. Such a system is particularly relevant for safety-critical offshore operations and environments with limited deck space.
Environmental Performance Benchmarking
The platform has maintained operational stability under high wind conditions and complex sea states. Compared with conventional multirotor UAV platforms, the unmanned helicopter configuration has demonstrated higher aerodynamic efficiency and an improved payload-to-range ratio. These characteristics have resulted in enhanced wind resistance and reduced sensitivity to maritime turbulence, establishing the platform as a robust tool for offshore supply delivery and emergency logistics support.
Logistics Infrastructure and Implications
The successful execution of this mission has provided a validated reference for extending shore-to-ship logistics networks. By integrating autonomous flight and non-contact delivery mechanisms, the company has established a scalable model for next-generation maritime logistics. These advancements demonstrate that unmanned platforms can effectively bridge the gap between low-altitude airspace operations and maritime transport systems.
