China’s ocean vessel upgraded to reach 32,000 feet deeper during critical sea operations

The Ocean University of China’s 1996 research vessel Dong Fang Hong 2 underwent a major refit in 2025.

Upgrades improved dynamic positioning, automated navigation, bridge visibility, lab space, and equipment support.

A new folding crane raises its operating depth from 6,000 meters to 10,000 meters.

The modernization will enable deeper, more complex marine research and strengthen international ocean science cooperation.
