Background
At present, polar region scientific investigation is mainly completed by a polar region scientific investigation ship, the polar region scientific investigation ship is generally a middle-grade or low-grade icebreaker, the reinforcing capacity of an ice region of the structure of the polar region scientific investigation ship is not high and generally does not exceed the PC3 grade, the icebreaking capacity is not strong, and the polar region scientific investigation ship cannot bear years of ice load and enter a central arctic region of the north pole, so that perennial scientific investigation operation of the central arctic region of the north pole is realized. Meanwhile, as most of the polar region scientific research ships need to perform the supply task of the south pole scientific research station, the ship phase for carrying out the north pole research is shorter. Taking a certain arctic scientific investigation voyage of the Xuelong 2 as an example, the time length of the whole voyage is only two and a half months, the time of polar region investigation is less than 50 days, the arrival position is 86 degrees in north latitude, and the requirement of scientific research can not be met in time and space. The polar region scientific investigation ship is generally higher in manufacturing cost, so that the polar region scientific investigation ship is mostly designed to be used for both scientific investigation and replenishment, under the condition of meeting certain scientific investigation capability and replenishment capability, the ice level is reduced, the cruising power, the scientific investigation capability and the cargo carrying capability are increased, and the cost is reduced. If a polar region scientific investigation ship is needed to be used for the central ocean region investigation of the north pole, the existing ship type is not suitable any more, and the scientific investigation cost is greatly increased.
The existing polar region scientific investigation ship has low reinforcing grade in an ice region and low ice breaking capacity, cannot enter a north region, and cannot carry out scientific investigation operation in a central ocean region of the north throughout the year; for the conventional high-ice-level icebreaker, because the icebreaker mainly aims at ice breaking during sailing, the probability of damage to other structures except the bow of the ship body after freezing in ice is greatly increased, and the application of the icebreaker in drifting operation in the central ocean area of the arctic is limited. Therefore, the technical problem of how to obtain a polar region scientific research drifting ship needs to be solved urgently in the technical field; it is urgently needed to design a polar region scientific research drifting ship/station/platform, which has a structural ice level of PC3 or above, adopts a special structural design and an attitude adjustment system, can reduce ice load of an ice belt structure under the freezing condition, has self-navigation capability in an open water area, drifts along with ice in a polar region, does not use self-power in the drifting process, and realizes long-term scientific research operation in the polar region.
