China's first self-built polar scientific icebreaker "Xuelong 2" was launched successfully in Jiangnan Shipbuilding (Group) Co., Ltd.
It is reported that the "snow dragon 2" by Finland Ak Arctic Technology Co., Ltd. is responsible for the basic design, China Shipping Group 708 Institute for detailed design. "Xuelong 2" has a total length of 122.5 meters, a design drainage of nearly 14,000 tons, a total length of 122.5 meters, 22.3 meters wide, structure draught 8.3 meters, loading capacity of about 4,500 tons, the maximum speed of 16.8 knots, structural strength to meet the requirements of PC3, with two-way ice breaking capacity; loaded full-rotation electric propulsion system and DP-2 dynamic positioning system, can be built at the same time. With two helicopters and international advanced marine environment and geophysical survey equipment, the ship can carry 90 scientific research personnel and crew, with a sustainability of 20,000 nautical miles, fresh water can be produced on board, and the self-sustainability can reach 60 days under the rated staffing.
"Xuelong 2" is a medium-sized ice-breaking vessel of International Polar mainstream, and the world's first polar scientific research ice-breaking vessel using bow, bow two-way ice-breaking technology. The design and construction of "Snow Dragon 2" conforms to the latest specifications, and the performance indexes are in the forefront of the world. It uses two way icebreaking design. When it is difficult to "arch" the ice ridge, the hull can rotate 180 degrees, so that the stern can be turned into a bow. The tail propeller can cut the ice under the sea surface and "hollow out" the ice ridge more than 10 meters high so as to break through the heavy encirclement. Fourthly, it is intelligent and has a smart cabin for the aircraft to take off and land on deck. It can monitor the whole life of the ship hull through sensors and other equipment, such as scraping with the ice surface, and can automatically warn.
