Content summary:
Snow dragon 2 is the world's first use ship bow, the ship stern two-way icebreaker polar ice technology research, a rotary electric propulsion function and crash ice-breaking ability, which can realize polar place turn 360 ° freedom, and break through the polar 20 m that year ice pressure ridge, global navigation ability, can satisfy the requirement of world-wide, safe navigation in the polar ocean. It has a length of 122.5 meters, a width of 22.32 meters, a design draft of 7.85 meters, a design displacement of 13,996 tons, a sailing speed of 12 to 15 knots, a sailing endurance of 20,000 nautical miles, and a self-sustaining power of 60 days. It can sail at 2 to 3 knots in a continuous ice-breaking voyage under the conditions of 1.5 meters of ice thickness and 0.2 meters of snow thickness. As the chief technologist of Snow Dragon 2, Zhao Zhenhua will introduce the technical indicators, characteristics, implementation of key technologies, experimental verification and construction process of Snow Dragon 2 in detail in this report.
Brief introduction of the speaker:
Zhao Zhenhua, senior engineer, director of outfitting design office of Jiangnan Research Institute, assistant director of supporting department of Jiangnan Shipbuilding (Group) Co., Ltd. He is fully responsible for the design of China's first independently built scientific icebreaker, and has rich theoretical knowledge and practical experience in ship shape design and digital shipbuilding. As one of the leaders of Jiangnan Shipbuilding's shipbuilding design technology, he is mainly engaged in the design and technology research in the fields of 3D simulation interactive design, special equipment design and installation elements, and cold-proof design in low temperature environment.
He has participated in the design work of 16500 cubic meter liquefied gas ship, 4600TEU ship, 35,000 cubic meter liquefied ethylene ship, 10,000 tons coast guard ship and other high-tech ships, and served as the chief technologist of Xuelong 2 polar scientific investigation icebreaker and Sun Yat-sen University scientific research ship. He has won many honors from the company, the group and the Society of Naval Architecture and Engineering, and has won many scientific research project awards and patent approval through technical accumulation. In 2017, he was awarded the second prize of Science and Technology Progress Award by Jiangnan Shipbuilding Group, and in 2018, he was awarded the Excellent Scientific and Creative Talents by the Chinese Society of Naval Architecture and Engineering.
