Details of the snow dragon

The polar scientific research ship "Snow Dragon" was built by Ukrainian Hellson Shipyard in March 1993 and refitted by Shanghai Hudong Shipyard for the second time. "Snow Dragon" has advanced navigation, positioning and automatic driving systems, and is equipped with advanced GMDSS communication system, complete medical facilities and living and entertainment facilities. The ship is equipped with a series of scientific investigation laboratories such as atmosphere, hydrology, biology, computer data processing center and meteorological analysis and forecast center, as well as marine scientific investigation instruments such as MK-3/WOCE-CTD, water sampler, 75KHZ ADCP and fish finder. In addition, the ship is equipped with A-frame, CTD winch, 3,000m hydrological winch and two 6,000m geological winches, which can undertake multidisciplinary marine comprehensive survey. The ship was originally designed as an Arctic multi-purpose transport ship with strong ice-breaking ability. It can continuously break through the ice layer with a thickness of1.2m at a speed of 0.5 knots. The ship is equipped with an adjustable propeller, which is flexible to operate when sailing and is conducive to breaking the ice. The hull made of E-grade steel plate will not be denatured even in the cold climate of MINUS 40 degrees Celsius. There are marine physics, marine chemistry, biology, meteorology and cleaning laboratories on board, covering an area of 200 square meters. It is also equipped with international advanced marine survey instruments and equipment such as CTD automatic water sampling system (measuring seawater temperature, depth and salinity), ADCP (profile current meter), high-resolution satellite cloud image system and EK5O0 scientific sonar system. A fish detector which can be used to explore krill and other polar aquatic animals was installed in the newly-built hydrological data collection room. A Doppler current meter that can measure the velocity and direction of seawater when sailing; In addition, scientific research facilities such as atmospheric sampling room, data processing center, sample room and telescopic crane have been built. Two sets of automatic collision avoidance radars with advanced level in 1990s are installed in the cab, which can measure the course and speed of the opposite ship or iceberg in time, and prompt how to avoid it correctly. The meteorological center set on board can receive meteorological data such as polar satellite cloud images in time, which provides safety guarantee for ships sailing in extremely harsh and changeable polar waters. Maritime aviation technical equipment can be used to park two Ka-32 helicopters. The landing platform is arranged on the center line of the poop deck, and helicopters can take off, land and park day and night. The navigation radar station equipped on the ship can monitor the take-off of the aircraft to ensure flight safety. In addition, swimming pools, gyms, libraries, karaoke rooms, medical rooms, operating rooms, laboratories and other entertainment, sports and health care facilities are readily available, providing a suitable living and working environment for boat people. After modification, the carrying capacity of the ship has increased from 55 to 78, and now it has increased to 130.
