Drifting ship for polar scientific investigation

Abstract

The invention relates to a polar scientific investigation drifting ship, and belongs to the technical field of ship design and manufacturing. The hull is of a main body structure with a small length-width ratio, the structural reinforcement level of the hull is greater than or equal to PC3 level, a spoon-shaped icebreaking bow is arranged at the bow part, an inclined ice discharging angle is arranged at the broadside, and an ice-level propeller is arranged at the tail part of the hull; a helicopter platform and a helicopter garage are arranged in a superstructure of the ship body; a posture adjusting system is arranged in the ship body. The polar region scientific investigation drifting ship / station / platform can bear ice pressure loads of polar region ice in all directions for many years, drifts along with the ice in floating ice and can meet the requirement for polar region long-term continuous scientific investigation operation, the broadside ice discharging angle and the posture adjusting system enable the drifting ship / station / platform to resist the ice extrusion loads in all directions, and the drifting effect is good. The icing probability and the heat loss can be reduced by the superstructure which is mostly closed and has a plump ellipsoid-shaped bow part; a helicopter platform and a helicopter library are arranged to widen the operation range.

Description

technical field [0001] The invention relates to a drifting ship for polar scientific research, which belongs to the technical field of ship design and manufacture. Background technique [0002] The current polar scientific investigations are mainly completed by polar scientific research ships, and polar scientific research ships are generally medium-level or low-level icebreakers. The multi-year ice load enters the Arctic central ocean area, realizing the perennial scientific research operations in the Arctic central ocean area. At the same time, since most of the polar scientific research ships still need to perform the replenishment mission of the Antarctic scientific research station, the sailing schedule for the Arctic research is even shorter. Taking a scientific research voyage of "Snow Dragon 2" in the Arctic as an example, the entire voyage lasted only two and a half months, and the survey time in the polar region was less than 50 days, and the arrival location was ...

At the same time, since most of the polar scientific research ships still need to perform the replenishment mission of the Antarctic scientific research station, the sailing schedule for the Arctic research is even shorter

Taking a scientific research voyage of "Snow Dragon 2" in the Arctic as an example, the entire voyage lasted only two and a half months, and the survey time in the polar region was less than 50 days, and the arrival location was 86 degrees north latitude, which was far from enough in terms of time and space. scientific research needs

[0003] Existing polar scientific research ships have low ice strengthening level and weak icebreaking ability, so they cannot enter the Arctic region, and cannot carry out scientific research operations in the central Arctic Ocean all the year round; The probability of damage to other structures of the hull except the bow will greatly increase after freezing in the ice, which limits its application in drifting operations in the central Arctic Ocean
