Unmanned helicopters can be used to monitor maritime vessel activities, including fishing, sand extraction, and waste disposal. Typical monitoring tasks include identifying anchoring, mooring, overloading, and other behaviors. By integrating with the AIS system, drones can match radar data and take action, such as confirming, tracking, and deterring unknown vessels. This reduces the need for personnel on the water, enhancing the efficiency of patrol and law enforcement efforts.

In areas with challenging access like remote islands, unmanned helicopters play a crucial role in smart island management. They can facilitate transportation between islands, assist in emergency search and rescue operations, supervise construction activities, and conduct island mapping. This provides an efficient and safe approach for both developing uninhabited islands and managing inhabited ones.

During marine research activities, drones serve as versatile aerial platforms equipped with various sensors to collect oceanographic and meteorological data. Unmanned helicopter platforms are characterized by their strong wind resistance, high payload capacity, high cruising speed, long endurance, and swarm capabilities. This enables more comprehensive and synchronized data collection, supporting oceanographic research conducted from research vessels. Their dynamic base technology allows for takeoff and landing without interrupting operations.

For coastal surveillance, drones provide an aerial overview with high-altitude perspectives. Patrol routes and missions can be stored for traceability and easy comparison of inspection results.
In terms of navigation aid inspections, drones can inspect the status of navigational facilities such as buoys and lighthouses. Equipped with high-resolution cameras and sensors, drones can perform aerial checks on lights, appearance, structural integrity, and more, aiding maintenance personnel in detecting damage or malfunctions.
