China's first large navigation mark ship with icebreaking function
On January 16, "Haixun 156", China's first large navigation mark ship capable of breaking ice, which was developed and designed by the 708th Institute of China Shipbuilding Corporation and built by Wuchang Shipbuilding, was officially listed, marking that the country currently has the largest displacement and the most comprehensive performance. The best and most intelligent large navigation mark ship was officially put into use.
"Haixun 156" has a total length of 74.9 meters, a molded width of 14.3 meters, a molded depth of 6.2 meters, and a displacement of about 2,400 tons. It adopts a full-electric drive, dual full-rotary rudder propulsion system, and has DP1 dynamic positioning capabilities. It has excellent performance in sea ice conditions. It can carry out continuous icebreaking operations at a speed of about 3.5 knots when the layer of ice is 0.6 meters, and can better ensure the smooth flow of ports and waterways and the safety of ships in harsh sea conditions such as cold waves, strong winds, and freezing. To ensure the emergency response capability in the northern seas during winter ice conditions.
"Haixun 156" is currently a large-scale navigation ship with the highest level of informationization and intelligence in China. It is also the first domestic large-scale navigation ship that meets the requirements of China Classification Society (CCS) for intelligent engine room and intelligent energy efficiency. It has intelligent decision-making support and maintenance. functions, reduce carbon emissions, save operating costs, and demonstrate good operating economy.
The listing of the "Hai Xun 156" has filled the gap of China's navigation mark ships have no ice-breaking capabilities. In the future, the ship will be mainly used for the maintenance of navigation aids in northern frozen ports and waterways, emergency search and rescue on water, and pollution cleanup tasks. is of great significance.
In addition, "Hai Xun 156" is also the large navigation ship of Dongbao Center ("Hai Xun 160") and the large navigation ship of Nanbao Center ("Hai Xun 173") delivered by 708 Institute in 2019 and 2020 respectively. No.), the ship will greatly improve the ability of the maritime system to serve the local economy.
