A major national science and technology infrastructure project, the deep-sea all-weather resident floating research facility, was officially launched in Shanghai on Saturday.
Dubbed the "Deep-Sea Floating Island", the world’s first ultra-large marine research platform is designed to support scientific research needs in fields such as marine equipment, marine resources, and marine science.
The large scientific installation comprises three primary components: the main facility platform, ship-based laboratories, and shore-based support.
The main platform is of an innovative semi-submersible twin-hull design, enabling full-scale testing of deep-sea equipment weighing hundreds of tons and supporting scientific exploration and experiments at full-ocean depths up to 10,000 meters.
The , undertaken by the Shanghai Jiao Tong University (SJTU), has been rated as a major national science and technology infrastructure project.
"We have various types of marine research facilities in our country, such as deep-sea laboratories, oceanographic research vessels, and deep-sea submersibles, but we lack a research facility that can both navigate quickly and remain in a mission area for extended periods. In efforts to address such a shortfall, we have combined the characteristics of semi-submersible platforms in the marine oil and gas field with those of research vessels to form a completely new concept for a semi-submersible research platform," said Xiao Longfei, a professor with the Shanghai Jiao Tong University, the university that was responsible for the development of the "Deep-Sea Floating Island".
The construction of the facility is scheduled for completion in 2030. As an open-sea testing ground, it will support trials of deep-sea mining systems, critical marine equipment, and offshore oil and gas infrastructure. It is expected to accelerate the commercial development of marine resources, reveal seasonal evolution patterns of marine ecosystems, explore the origins and evolution of life, and improve typhoon forecasting accuracy to enhance disaster prevention and mitigation capabilities.
"It can sail at roughly the same speed as the research vessel. Once it reaches the operational area, it can be ballasted to conduct research and experiments. With its super-heavy load capacity, super-long stay capability, and super-strong typhoon resistance, it can conduct this kind of work in harsher sea conditions, for longer periods, and in deeper waters," said Yang Jianmin, an academic researcher with the Shanghai Jiao Tong University.
