Today (December 26), the "Exploration No. 3", a multifunctional deep-sea scientific survey and cultural relic archaeology ship independently designed and built by my country, was officially delivered and set sail in Nansha, Guangzhou. "Exploration No. 3" is my country's first comprehensive scientific research ship with the ability to cover global deep-sea exploration and support manned deep diving in ice areas.

The "Exploration No. 3" is about 104 meters long, with a displacement of about 10,000 tons, a maximum speed of 16 knots, bidirectional icebreaking, a cruising range of 15,000 nautical miles, and a crew of 80. For the first time, it has completed the research and installation of domestic technologies such as a full range of polar operation scientific research control equipment, the largest watertight scientific research moon pool system equipment in China, deep-sea acoustic detection, communication and positioning equipment in ice areas, and ship dynamic positioning systems.

During the research and development process, various research institutions, enterprises, and universities have worked together to tackle key core technologies, breaking through the monopoly bottlenecks of many key technologies such as key design technologies for ships in ice areas, high-precision dynamic positioning control technologies under ice loads, and intelligent ship control technologies, enabling my country's manned deep-sea diving capabilities to expand from full sea depths to all sea areas.
