In a major leap for deep-sea exploration, the Chinese mainland has commissioned its first seven-function deep-sea robotic arm for offshore oil and gas operations. Developed by Offshore Oil Engineering Co., Ltd. (COOEC), the mechanical arm is mounted on a remotely operated vehicle (ROV) and successfully completed precision tasks during its inaugural deployment in the Pearl River Mouth Basin.
Boasting a maximum operating depth of 7,000 meters, the arm mastered seven capabilities—extending, retracting, swinging, rotating, opening, grasping and clamping—to carry out valve operations and equipment installation against strong currents. At just 60 kilograms, it is 35 percent lighter than similar global models, yet it can handle a 125-kilogram payload at full extension.
With production costs 40 percent lower than imported alternatives, the new arm advances the Chinese mainland into an elite group of nations capable of manufacturing critical deep-sea robotics. As global demand for offshore technology grows, this homegrown innovation could reshape the market and inspire further breakthroughs in marine exploration.
