      China's first deep-sea multi-functional research vessel completes trial voyage

      China's first deep-sea multi-functional scientific research and archaeological vessel completed its trial voyage and returned to Guangzhou, capital city of south China's Guangdong Province on Saturday, with all trial results up to standard.

      During its eight-day trip, the ship completed various tests spanning 30 categories, such as speed measurement, maneuverability, underwater radiated noise, informatization, and intellectualization, with the results all meeting standards and some even exceeding the design objectives.

      The vessel "Tansuo-3", independently built by China's prominent shipbuilding company Guangzhou Shipyard International (GSI), reportedly has a number of iconic features, including manned deep-sea diving, deep-sea detection, heavy-duty safety payload capabilities and comprehensive operational support.

      Additionally, it boasts a total length of approximately 104 meters, a design displacement of around 10,000 tons, a range of 15,000 nautical miles, and can accommodate up to 80 crew members.

      It is China's first comprehensive scientific research vessel able to conduct deep-sea exploration worldwide and support manned deep-sea diving in ice areas.

      "During the trial, the vessel encountered the sea state code 5 with the wave height reaching more than four meters. Despite these conditions, it was able to sail at full speed, demonstrating its impressive seakeeping performance. The vessel is also capable of breaking through sea ice up to 1.2 meters thick, plus 0.2 meters of snow. Furthermore, it features a bidirectional function, ensuring its high icebreaking efficiency," said He Guangwei, GSI's deputy chief engineer.

      The "Tansuo-3" vessel is equipped with homemade scientific research equipment adapted to the environment of polar regions.

      In addition to the scientific research operation stations at the stern and side of the vessel, a large moon pool was also built to serve as the third station to improve the environmental adaptability to high sea state and floating ice operating conditions.

      "It can support manned submersibles to carry out sophisticated underwater operations, which is one of the highest technical levels of China's deep-sea scientific research vessels in organizing and implementing comprehensive seabed operations. It has comprehensively improved our country's comprehensive deep-sea survey capabilities," said Tanggu Lashan, chief engineer at the Institute of Deep-sea Science and Engineering under the Chinese Academy of Sciences.

      New roads leading to Medog realize Xizang's long-held dreams

      Two roads leading to Medog County, nestled deep within the Himalayas of southwest China's Tibet Autonomous Region, have fulfilled the long-held aspirations of its local community.

      At a relatively low average elevation of 1,200 meters, Medog in the city of Nyingchi, was once the last county in China without permanent road access. The place has much more moisture in its air than other place in the region, fostering year-round frost, rain, snow and heavy fog.

      Facing the tough geography and climate, China's outstanding engineers, however, build roads through mountains and bridges over rivers. They also bored a 3-kilometer-long tunnel facing the magnificent, snow-capped Galongla Mountain, and set up long sections of shed tunnels to shelter their road from frequent avalanches.

      The Medog Highway, the first highway leading to Medog with a total length of 117 kilometers, opened to traffic in October 2013 after more than 50 years of sincere efforts, connecting the county with Zhamog Township of Bomi County in Nyingchi.

      According to statistics, since its opening, the highway has endured 652 continuous heavy rainfalls, 265 heavy snowfalls, 258 slope and subgrade collapses, 394 mudslides and 71 avalanches. Therefore, efforts to upgrade the highway have never stopped over the past decade.

      In October 2022, construction of a second highway was completed. The second passageway to Medog is a 67.22-km highway connecting Pad Township in the city of Nyingchi and Medog County.

      After the new highway was opened to traffic, the length of the road connecting the city proper of Nyingchi and Medog County was shortened to 180 kilometers from 346 kilometers, cutting travel time to four hours, and it only takes three hours to drive to Nyingchi Mainling Airport from Medog.
