On December 26, China’s first deep-sea multi-functional scientific research and archaeological vessel “Tansuo-3 (Exploration-3)”, built by Guangzhou Shipyard International (GSI) under China State Shipbuilding Corporation (CSSC), with completely independent intellectual property rights, was officially delivered in Nansha, Guangzhou.
It is reported that Tansuo-3, with a length of about 104 meters and a displacement of about 10,000 tons, has the ability to break ice in both directions, and is China’s first comprehensive research vessel with the ability to cover the global deep sea exploration and to support manned deep diving in the ice area.
For the first time, GSI has completed the research and installation of all series of polar operation research manipulation equipments and the largest water-tight research moon pool system equipments in China, deep-sea acoustic detection, communication and positioning equipments in the ice area, and ship power positioning system and other localized technologies.
During the research and construction of Tansuo-3, GSI broke through the monopoly bottlenecks of many key technologies, such as key design technology of ships in ice area, high-precision power positioning control technology under ice load, intelligent ship control technology, etc., so that China’s manned deep-diving capability will be expanded from the full depth of the sea to the whole sea area, and will effectively enhance China’s deep-sea archaeological operation capability.
It is worth noting that the localization rate of “Tansuo-3” has been extended from the localization of key core equipment to the localization of key core control systems on board, including the localization of power control, power positioning control system and integrated control system of cabin and cockpit, so as to realize the autonomy and control of key core technologies.
In addition, “Tansuo-3” has also obtained four intelligent ship classification notations, which is a useful exploration for the development of ship digitization and intelligence.
