China News Service, Beijing, December 12 (Reporter Pang Wuji) The reporter learned from the China Geological Survey of the Ministry of Natural Resources of China on the 27th that China's first ocean drilling ship "Dream" met or exceeded the design of the first sea trial, and the sea trial was a complete success.
It is understood that the trial voyage was launched in Nansha, Guangzhou on December 12, "Dream" relied on its own power to leave the wharf, with a total voyage of about 18 nautical miles, a total of more than 500 engineering and technical personnel and management personnel participated, through the individual and joint commissioning of various systems under navigation conditions, successfully completed the commissioning of 200 key marine systems such as ship power station, propulsion system, communication and navigation, life-saving anchorage, etc., and completed the navigation test and international certification related projects as planned. The analysis of hull inspection and trial data shows that the main power and other marine systems have been verified, and the performance and various indicators meet or exceed the design requirements.
The total tonnage of "Dream" is about 33000,179 tons, With a total length of 8.15000 meters and a endurance of 11000,150 nautical miles, it has the ability to operate in the unlimited navigation area of the global sea area and the drilling capacity of 2021,11 meters in the sea area, organized and built by the China Geological Survey of the Ministry of Natural Resources, and the China Shipbuilding Group undertook the design and construction tasks, and more than 30 participating units worked closely together to officially start construction on November 2022, 12, realize the main hull breakthrough of the ship on December 18, 2023, officially named and start sea trials on December 12, 18, and are expected to be fully completed in 2024.
