Fujian's First Low-Altitude Maritime Service Goes Live | Grey Whale G1 Validates Ship-to-Ship Resupply and Inter-Island Transport

Low-altitude maritime logistics is no longer a concept.
It’s now flying real missions over real oceans.

And one question keeps coming up in the maritime industry:

How do you deliver supplies to moving ships quickly, safely, and without relying on traditional vessels?

Another one:

How do islands maintain stable logistics when weather, schedules, and sea conditions constantly slow everything down?

In May 2026, a live operational test in Pingtan, Fujian gave the industry a real answer.

Using the ZIYAN Technology Grey Whale G1 unmanned helicopter, the mission successfully completed both:

• Underway vessel resupply

• Inter-island cargo transport

This also marked the first verified deployment of a digital low-altitude maritime service system in Fujian Province.

A Real Maritime Logistics Test in Extreme Sea Conditions

The test took place in the western inland channel of the Pingtan Comprehensive Experimental Zone.

This area is known for strong crosswinds and unstable sea conditions caused by the “narrow tube effect”.

In simple terms:

It’s one of the worst places to fly if your UAV platform isn’t built properly.

The mission was carried out in wind gusts approaching Force 8.

That matters because maritime UAV operations are not tested in perfect weather.

They’re tested when conditions become unpredictable.

For the Grey Whale G1, this mission became a live validation of:

• Wind resistance

• Flight control precision

• Stability over open water

• Autonomous maritime operations

Maritime Resupply “Like Ordering Food Online”

The operation started with a vessel already underway at sea.

Using the self-developed “Guoyuan eDa” low-altitude maritime service mini-program, the crew submitted a delivery request for approximately 10kg of ship supplies.

Once the order was received onshore, the system rapidly completed:

• Cargo preparation

• Payload securing

• Route planning

• Flight checks

All within 30 minutes.

Then the Grey Whale G1 took off from shore.

The UAV flew approximately 10km across the sea.

Despite strong airflow disturbances and changing maritime conditions, the aircraft maintained stable flight throughout the route.

Only 9 minutes later, it arrived above the moving vessel.

Mission Highlights

• 9 minutes total delivery time

• 10km maritime flight route

• Near Force 8 winds

• No vessel docking required

This is where traditional maritime logistics starts losing efficiency.

And where low-altitude UAV logistics starts becoming commercially valuable.

Dynamic Ship Resupply Was the Real Challenge

The hardest part of the mission was not crossing the sea.

It was supplying a vessel that never stopped moving.

The target ship continuously changed:

• Speed

• Heading

• Position

At the same time, the UAV faced heavy side winds over open water.

To complete the mission safely, the Grey Whale G1 relied on its high-precision flight control system to achieve:

• Real-time vessel motion tracking

• Same-speed escort flight

• Direction synchronisation

• Stable hovering above deck

Once positioning was locked, the onboard intelligent winch system lowered the cargo vertically onto the deck.

No slowing down.

No docking.

No interruption to vessel operations.

After delivery, the UAV automatically retrieved the lifting device and safely returned to base.

This is a major step forward for autonomous maritime drone logistics.

Inter-Island Transport Was Also Successfully Verified

The operation didn’t stop at ship resupply.

The team also conducted a live inter-island logistics demonstration.

Traditionally, island cargo transport depends heavily on boats.

That creates several problems:

• Slow response times

• Weather delays

• High operating costs

• Scheduling bottlenecks

The Grey Whale G1 changes that model completely.

Using autonomous low-altitude logistics routes, the platform can establish stable point-to-point aerial transport corridors between islands, ports, and offshore facilities.

Grey Whale G1 Transport Performance

• 20km range with 15kg payload

• 25km range with 12kg payload

• 33km range with 10kg payload

That opens practical use cases for:

• Island-to-island logistics

• Island-to-port resupply

• Offshore platform delivery

• Emergency material transport

• Maritime inspection support

During the live demonstration, the Grey Whale G1 transported cargo from Island A to Island B using a preset autonomous route.

The onboard winch system completed precise aerial delivery at the destination point.

The result was a repeatable and stable cross-island transport workflow ready for larger-scale deployment.

Three Major Breakthroughs Behind This Maritime UAV Mission

1. Full Digital Logistics Workflow

The “Guoyuan eDa” platform connected:

• Vessel-side ordering

• Shore-side dispatch

• Airborne execution

Everything operated inside one integrated digital workflow.

That dramatically improves maritime logistics response efficiency.

2. Stable Operations in Extreme Maritime Conditions

Completing the mission in near Force 8 sea winds validated the Grey Whale G1’s:

• Disturbance resistance

• Flight stability

• Autonomous control capability

• Maritime operational reliability

This is critical for real-world offshore UAV deployment.

3. One Platform, Multiple Maritime Scenarios

The same UAV platform successfully handled:

• Moving vessel resupply

• Fixed-route island logistics

That means operators can deploy a single aerial logistics system across multiple maritime applications.

From Successful Validation to Scaled Maritime UAV Operations

The successful deployment in Fujian represents more than a single test flight.

It shows that digital low-altitude maritime services are moving from concept into operational reality.

With coordinated support across airspace management, maritime operations, and digital dispatch systems, this project also creates a scalable reference model for the wider low-altitude economy.

From:

• Mobile ordering

• To direct deck delivery

• To island-to-island aerial logistics

…the Grey Whale G1 is helping build a new digital aerial supply network connecting land, islands, and offshore operations.

At ZIYAN Technology, we’ll continue expanding unmanned helicopter applications across:

• Maritime operations

• Energy infrastructure

• Emergency response

• Offshore logistics

• Industrial inspection

Because complex missions need platforms built for complex environments.

And that’s exactly what the Grey Whale G1 unmanned helicopter was designed to do.
