Underwater Drone Demonstration Experiment for Ship Bottom Inspection

We conducted a demonstration experiment using an underwater drone to inspect the bottom of a ship.


The experiment was conducted using “M2 PRO”, an industrial underwater drone developed by CHASING, on the containership ONE THESEUS, operated by Ocean Network Express (ONE) and managed by NYK Ship Management, anchored in Kobe Port on May 30, and on the containership ONE FALCON, anchored in Singapore on June 14, with the following significant results.


Crew can:

・ easily maneuver and take pictures while watching the monitor.

・ check for marine organisms (algae, etc.) on the bottom and stern of the vessel, which can cause fuel consumption to deteriorate.

・ check the paint condition of the hull and the damage in case of an accident, leading to

prompt diver arrangements and cleaning implementation.


We have been involved in demonstration experiments using aerial drones to inspect ship holds, tanks, etc.

In the future, we will also utilize underwater drones and promote various initiatives to expand the scope of imaging and usage methods.


※ Features of M2 PRO

① Stable high quality images with 4K camera, EIS (Electronic Image Stabilization), and 4000

lumen LED light, as well as still images and slow-motion shooting.

② Capable of a maximum depth of 150 m and a maximum horizontal travel distance of 400 m, and

can freely move 360 degrees underwater with its eight thrusters.

③ The ability to operate continuously for long periods of time thanks to the interchangeable
