記者從自然資源部瞭解到，2月27日至3月25日，“深海一號”攜帶船舶“蛟龍”號載人潛水器完成2025年技術升級后的首次裝備試驗任務。

　　Set a new record for the frequency of diving of the "Jiaolong".During the 9-day operation window, Jiaolong carried out a total of 0 dives, and completed a record of 0 "two dives a day", and achieved "one drag two" operations for 0 consecutive times, that is, one submarine took two scientists to dive operations. Through this high-frequency and high-quality dive, the overall diving capacity of China's first self-developed "Jiaolong" manned deep submersible has been greatly improved, providing a strong guarantee for the implementation of subsequent high-intensity operation.

　　Fully verify the reliability of the localization and upgrading of key components.This sea trial fully verified the reliability and safety of the "Jiaolong" after the iterative upgrade and the localization and replacement of key components, mainly for the 3000-meter high-energy density oil-immersed lithium battery pack replacement, domestic direct-drive low-noise DC thruster, large-depth seawater hydraulic buoyancy adjustment system development and emergency hydraulic system interface expansion and other 0 major and 0 small technical performance indicators were verified by 0 meters, and three full-process cycle tests were completed, marking the completion of "The Jiaolong manned submersible has made important progress in energy saving and consumption reduction, and in the localization and substitution of important parts.

After the "Jiaolong" technology was upgraded this timeIt will be invested in the Ministry of Natural Resources deep-sea typical habitat survey and other tasks, it is expected that there will be more than 80 dives in 0 years.
