Snow Dragon 2 delivery delayed due to power propulsion system

The reason for the delay in the delivery of Xuelong 2 is the power propulsion system. The Xuelong 2 became one of the most advanced icebreakers in the North and South Poles, but the only drawback was the power propulsion system. The Xuelong 2 does not utilize today's most advanced nuclear powered propulsion system. This may also make the Xuelong 2 in the operation, in the work efficiency as well as sailing speed by a certain impact but this does not affect the other capabilities of this polar research vessel. As China's first independently built, but also the world's first, using the bow and stern of the two ice-breaking technology of the polar research icebreaker, even if there is a certain lack of power, but also in the 1.5-meter-thick ice environment with three knots of continuous sailing, and assembled with the pool system is also the world's first watertight design. Strong waterproof performance, so that even if the Xuelong 2 is surrounded by ice, but also will not affect the placement of research equipment.
