Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a design method for a ship with polar drifting and icebreaking functions. Background Art

[0002] The polar regions generally refer to the portion of the Earth's surface bounded by the 66°34' parallel, encompassing the North Pole and the South Pole. These two regions complement each other in a unique ecological environment. Summers are characterized by abundant daylight, while winters are characterized by long, dark nights. These sparsely populated regions are closely related to issues such as space exploration, aviation, navigation, and human survival, necessitating the long-term development of polar scientific research.

[0003] Currently, polar research typically involves polar icebreaker vessels and polar research stations. The construction of polar research stations must take into account the impact on the local ecological environment, implement strict environmental protection measures, minimize disturbance to polar ecosystems, and take measures to prevent pollution and ecological damage. However, even with these environmental protection measures, the construction and operation of research stations will still place certain pressures on fragile polar ecosystems. Furthermore, the construction and maintenance costs of polar research stations are extremely high, including energy supply, equipment maintenance, personnel training, and logistical support. Their remote locations also significantly increase transportation and repair costs. Furthermore, research stations are large, encompassing living quarters, laboratories, observatories, and other facilities, all of which require significant capital investment and ongoing operational management. As global temperatures rise, the polar ice surface becomes unstable, creating an unsafe and precarious research environment at polar research stations. The use of polar icebreaker vessels can address these issues, but polar research vessels, which primarily focus on ice navigation and icebreaking capabilities, have relatively low self-sustaining capacity and are therefore unable to meet the demands of long-term polar research.

[0004] Therefore, a ship design method with polar drifting and icebreaking functions is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a ship design method with polar drifting and icebreaking functions, which can improve the icebreaking ability of polar icebreaking research vessels and meet the needs of long-term scientific research.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A method for designing a ship with polar drifting and icebreaking capabilities includes the following steps:

[0008] The angle between the portion of the longitudinal section line of the ship below the waterline and the sea level forms a bow angle, and the bow angle is set at 25°-30°;

[0009] The angle between the tangent line of the waterline of the ship and the longitudinal section line forms a waterline angle, and the waterline angle is set at 30°-40°;

[0010] The camber angle of the vessel is set at 30°-60°;

[0011] A mooring assembly is arranged on the ship, and when it is winter, the ship is fixed to the ice surface through the mooring assembly.

[0012] In some embodiments, the camber angle gradually increases from below the waterline to above the waterline.

[0013] In some embodiments, an ice foot is provided at the bottom of the bow of the vessel.

[0014] In some embodiments, the surface of the ice foot is treated to prevent rust.

[0015] In some embodiments, ice fins are provided on both sides of the bow of the vessel.

[0016] In some embodiments, the surface of the ice fin is treated to prevent rust.

[0017] In some embodiments, a reinforcing support structure is provided inside the ice fin.

[0018] In some embodiments, the hull line of the vessel is inclined downward toward the side of the ship in a vertical direction, and the inclination angle is 8°-10°.

[0019] In some embodiments, the mooring assembly includes a mooring line and a mooring anchor post, the mooring anchor post is connected to the ice surface by freezing, and the mooring line is connected to the mooring anchor post.

[0020] In some embodiments, a plurality of the mooring assemblies are spaced apart along the circumference of the vessel.

[0021] Beneficial effects of the present invention:

[0022] The present invention provides a design method for a ship capable of polar drifting and icebreaking. The angle between the portion of the ship's longitudinal section line below the waterline and sea level forms a bow angle, set at 25°-30°. The angle between the tangent to the ship's waterline and the longitudinal section line forms a waterline angle, set at 30°-40°. The ship's camber angle is set at 30°-60°. Furthermore, a mooring assembly is arranged on the ship, securing the ship to the ice surface via the mooring assembly. Through appropriate ship design, a bow angle of 25°-30° allows the ship to impart greater bending force to the ice. During icebreaking, the ship rides on the ice, crushing the ice with its weight, thereby improving icebreaking performance compared to crashing into the ice. A waterline angle of 30°-40° and a camber angle of 30°-60° enhance ice-discharging capabilities and reduce ice accumulation that increases icebreaking resistance. The ship's superior icebreaking capabilities can be utilized for navigation in summer. In winter, the mooring components on the vessel can be used to secure the vessel to the ice surface, thereby improving the vessel's self-sustaining ability and allowing it to drift with the ice in winter, thus solving the problem that polar research vessels cannot meet the requirements of long-term polar research. Through the above design, the icebreaking capability of polar icebreaker research vessels can be improved and the needs of long-term research can be met. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Currently, polar research typically involves polar icebreaker vessels and polar research stations. The construction of polar research stations must take into account the impact on the local ecological environment, implement strict environmental protection measures to minimize disturbance to polar ecosystems, and take measures to prevent pollution and ecological damage. However, even with these environmental protection measures, the construction and operation of research stations will still place certain pressures on fragile polar ecosystems. Furthermore, the construction and maintenance costs of polar research stations are extremely high, including energy supply, equipment maintenance, personnel training, and logistical support. Their remote locations also significantly increase transportation and maintenance costs. Furthermore, research stations are large in scale, encompassing living quarters, laboratories, observatories, and other facilities, all of which require significant capital investment and ongoing operational management. As global temperatures rise, the polar ice surface becomes unstable, making the research environment at polar research stations unstable and unsafe.

[0036] In order to use research vessels instead of research stations to solve the above problems, while ensuring the icebreaking capability of polar icebreaking research vessels and meeting the needs of long-term research, such as Figures 1-4 As shown, the present invention provides a method for designing a ship with polar drifting and icebreaking functions. The method for designing a ship with polar drifting and icebreaking functions includes the following steps:

[0037] The angle between the portion of the longitudinal section line of the vessel 1 below the waterline and the sea level forms a bow angle A, and the bow angle A is set at 25°-30°;

[0038] The angle between the tangent line of the waterline of the vessel 1 and the longitudinal section line forms a waterline angle B, and the waterline angle B is set at 30°-40°;

[0039] The camber angle C of the vessel 1 is set at 30°-60°;

[0040] A mooring assembly is arranged on the vessel 1. When it is winter, the vessel 1 is fixed to the ice surface through the mooring assembly.

[0041] By rationally designing vessel 1 and adopting a bow angle A of 25°-30°, vessel 1 can impart greater bending force to the ice. During icebreaking, vessel 1 can ride on the ice, crushing the ice with its weight, improving icebreaking performance compared to crashing into the ice. The waterline angle B is designed to be 30°-40°, and the camber angle C is designed to be 30°-60°, which can enhance ice-discharging capacity and reduce ice accumulation that increases icebreaking resistance. In summer, vessel 1 can utilize its superior icebreaking capability for navigation. In winter, the mooring components on vessel 1 can be used to secure vessel 1 to the ice surface, thereby enhancing vessel 1's self-sustaining capacity and enabling it to drift with the ice during winter, thus resolving the issue of polar research vessels being unable to meet the requirements of long-term polar research expeditions. The above design improves the icebreaking capability of polar icebreaker research vessels and meets the needs of long-term research expeditions.

[0042] In some embodiments, the camber angle C gradually increases from below the waterline to above the waterline. The above design can further improve the ice removal capability of the ship 1, reduce the accumulation of broken ice and increase the icebreaking resistance.

[0043] In some embodiments, an ice foot 11 is installed at the bottom of the bow of vessel 1. This provides protection, effectively safeguarding the bow of vessel 1 and enhancing its ability to withstand ice impact and friction during icebreaking. Ice foot 11 is typically designed with a sharp, V-shaped or scissor-like shape. Made of high-strength steel, it shears ice from both sides as vessel 1 moves forward, quickly breaking it and smoothly separating it from the hull. The cutting action of ice foot 11 breaks the ice into smaller chunks, which can be more easily pushed aside or bypassed by vessel 1. Furthermore, the design of ice foot 11 helps vessel 1 maintain stability in the ice, preventing excessive stress on the hull due to ice pressure. To further improve icebreaking efficiency, vessel 1 typically injects water beneath the ice to create a lubricating effect called water-thin ice. This design significantly reduces friction during icebreaking, improving the efficiency of the icebreaker. The design of ice legs 11 also takes into account varying ice thicknesses. When the ice is thick, vessel 1 needs to take additional measures, such as using a powerful charging device to ram the ice and break it using the pressure of the hull. This charging method effectively utilizes the mass and power of the hull to overcome the resistance of the ice.

[0044] In some embodiments, the surface of the ice foot 11 is treated with anti-rust paint. By applying anti-rust paint on the surface of the ice foot 11, the ice foot 11 can be isolated from seawater, thereby preventing seawater from corroding the ice foot 11, playing a protective role for the ice foot 11, and extending the service life of the ice foot 11.

[0045] In some embodiments, ice fins are provided on both sides of the bow of the vessel 1. As an extension structure of the hull underwater, the ice fins can transfer the weight and power of the hull to the ice layer in a more concentrated manner during the icebreaking process, thereby increasing the pressure on the ice layer and helping the vessel 1 to break the ice layer more easily. When sailing in ice areas, the irregular shape and distribution of the ice layer may cause the vessel 1 to be subjected to uneven external forces, thereby causing roll. The ice fins can provide a certain amount of resistance and support underwater, reduce the roll amplitude of the vessel 1, and improve the stability of the vessel 1. This is very important for ensuring the safety of people and cargo on board. The ice fins can also play a certain stabilizing role on the heading of the vessel 1, just like a rudder. When the vessel 1 is sailing in an ice area, the friction and impact force of the ice layer may cause the vessel 1 to deviate from the predetermined heading. The ice fins can generate a stable lateral force by interacting with the water flow, helping the vessel 1 to maintain a straight sail and reduce heading deviation.

[0046] In some embodiments, the surface of the ice fin is treated with anti-rust paint. By applying anti-rust paint on the surface of the ice fin, the ice fin can be isolated from the seawater, thereby preventing the seawater from corroding the ice foot 11, playing a protective role on the ice fin and extending the service life of the ice fin.

[0047] In some embodiments, a reinforcing support structure is provided inside the ice fin, which can further enhance the structural strength of the ice fin and extend its service life.

[0048] In some embodiments, the ship's hull lines are vertically inclined downward toward the ship's side, with an inclination angle D of 8°-10°. Since ship 1 drifts with ice when moored in winter, this design can reduce the compressive load on ship 1 caused by the ice, improving safety in ice-bound drifting while also increasing the deck area.

[0049] In some embodiments, the mooring assembly includes a mooring line and a mooring post, wherein the mooring post is connected to the ice surface by freezing, and the mooring line is connected to the mooring post. By arranging the mooring assembly on the vessel 1, the vessel 1 can be effectively fixed to the ice surface, thereby improving the safety of the vessel 1 when drifting on ice.

[0050] In some embodiments, multiple mooring assemblies are arranged at intervals along the circumference of the vessel 1. Through the above design, when the vessel 1 is drifting in ice, multiple mooring assemblies are used to secure the vessel 1, thereby further improving the safety of drifting in ice.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
