100-metre-tall watchtower to survey ocean in East China Sea and help protect Beijing’s ‘maritime rights’: state media
- Tongji Hai-1 multi-tiered stereoscopic tower base observation platform reported as world’s most advanced observation tower for comprehensive scientific research
- The project aligns with China’s ambition to be a prominent maritime nation

A new ocean observation structure that sits more than 100 metres above sea level and weighs over 4,500 tonnes is a significant leap in China’s marine research capabilities and will protect its maritime rights, according to a Chinese newspaper.
Once installed it will be the world’s most advanced observation tower for comprehensive scientific research, according to Science and Technology Daily.
The project, contracted by China Offshore Oil Engineering Co Ltd (CNOOC Engineering), will allow at least 66 diverse types, or 195 sets of observation equipment, to gather environmental and oceanic data.
“The platform facilitates real-time, high-resolution three-dimensional observations of the atmosphere, hydrosphere and lithosphere,” the report said.
It said the platform’s devices would continuously monitor environmental data, delivering precise oceanographic big data services crucial for research on climate change and serve as an early warning system for maritime disasters.
