Description

Technical Field

[0001] The present application relates to the technical field of wind-propelled ships, and in particular to a design method for a living building of a wind-propelled ship. Background Art

[0002] The shipping industry is facing unprecedented environmental pressure. The International Maritime Organization (IMO) requires that greenhouse gas emissions from the shipping industry be reduced by 50% by 2050 compared to 2008 levels, necessitating fundamental technological innovation. At its 83rd meeting in 2025, the Marine Environment Protection Committee (MEPC) proposed new fuel standards, requiring ships to reduce greenhouse gas (GHG) fuel intensity annually. Wind power is the only energy source capable of achieving zero-emission propulsion throughout its lifecycle. Currently, wind-propelled ships can improve energy efficiency by 20-40% through the integration of aerodynamic optimization, enabling shipowners to maintain a competitive advantage under increasingly stringent environmental regulations. In the long term, wind-propelled ships represent the future direction of shipping technology. This innovative ship type will provide the shipping industry with clean, efficient, and economical solutions, driving the shipping industry steadily towards its zero-carbon goals, and has important strategic value and practical significance.

[0003] Wind-propelled ships rely primarily on wind energy for propulsion, and their design requires minimizing resistance. The wind resistance of such ships is primarily composed of the wind propulsion units, the living quarters, and the hull above the waterline. Because they primarily rely on wind energy for propulsion, the wind propulsion units installed on the deck are often numerous and large in size, which significantly increases wind resistance and affects the view from the bridge. In actual navigation, the wind resistance of traditional ships accounts for approximately 2% of the total ship resistance. For wind-propelled ships, when using six wind propulsion units, the wind resistance accounts for approximately 4% of the total ship resistance. Without any optimization, the speed is reduced by approximately 0.04 knots.

[0004] In existing wind-propelled ships, the wind resistance generated by the living quarters accounts for about 30-40% of the total wind resistance. The wind resistance generated by the living quarters is relatively large, affecting the operating efficiency of the ship.

[0005] Therefore, we propose a design method for the living quarters of wind-powered ships.

[0006] Application Contents

[0010] A wind propulsion device is installed on at least one side of the deck of the hull above the waterline;

[0011] The main structure of the living building is set at the stern behind the wind propulsion device;

[0012] The main structure of the living building includes the first and second living building doorposts set on both sides of the deck.

In the direction of the ship length, the axis of the first living building doorpost and the axis of the wind propulsion device are in the same straight line, the width of the first living building doorpost increases, and the width of the second living building doorpost decreases.

[0017] The width of the first living building doorpost is greater than the width of the second living building doorpost.

[0021] The first living building doorpost and the second living building doorpost have a certain width and are used for arranging rooms, warehouses, and equipment.

[0022] The top floor of the living building is a cockpit, which reduces the windward area of ​​the top floor of the living building.

[0031] The specific implementation of this application is described below with reference to the accompanying drawings.

[0032] A method for designing a living quarters for a wind-powered ship comprises the following steps:

[0033] A wind propulsion device is provided on at least one side of the deck of the hull 11 above the waterline;

[0034] The main structure of the living building is arranged at the stern 1 behind the wind propulsion device;

[0035] The main structure of the living building includes the first living building doorpost 2 and the second living building doorpost 4 arranged on both sides of the deck.

[0036] A living building top floor 3 is provided on the top of the first living building doorpost 2 and the second living building doorpost 4. The living building top floor 3 is extended in the direction of the ship's length to ensure that the utilization space of the living building top floor 3 remains unchanged.

[0037] In one embodiment, wind propulsion devices are provided on both sides of the deck of the hull 11 above the waterline. In the direction of the ship length, the axis of the first living building doorpost 2 is in the same straight line with the axis of the wind propulsion device on one side, and the axis of the second living building doorpost 4 is in the same straight line with the axis of the wind propulsion device on the other side. The widths of the first living building doorpost 2 and the second living building doorpost 4 are the same.

[0038] In one embodiment, the deck of the hull 11 above the waterline is provided with a wind propulsion device only on one side of the first living building doorpost 2. In the direction of the ship length, the axis of the first living building doorpost 2 and the axis of the wind propulsion device are in the same straight line, the width of the first living building doorpost 2 is increased, and the width of the second living building doorpost 4 is reduced.

[0039] The width of the first living building doorpost 2 is greater than the width of the second living building doorpost 4.

[0040] In one embodiment, the deck of the hull 11 above the waterline is provided with a wind propulsion device only on one side of the second living building doorpost 4. In the direction of the ship length, the axis of the second living building doorpost 4 and the axis of the wind propulsion device are on the same straight line, the width of the second living building doorpost 4 is increased, and the width of the first living building doorpost 2 is reduced.

[0041] The width of the second living building doorpost 4 is greater than the width of the first living building doorpost 2.

[0042] In one embodiment, the first living building doorpost 2, the second living building doorpost 4 and the living building top floor 3 are rounded.

[0043] In one embodiment, the first living building doorpost 2 and the second living building doorpost 4 have a certain width for arranging rooms, warehouses, and equipment.

[0044] One end of the hull 11 above the waterline is the stern 1 , and the other end of the hull 11 above the waterline is the bow 12 .

[0045] In one embodiment, the top floor 3 of the living building is a cockpit, which reduces the windward area of ​​the top floor 3 of the living building.

[0046] In one embodiment, the width of the first living building doorpost 2 is L1, the width of the second living building doorpost 4 is L2, and the heights of the first living building doorpost 2 and the second living building doorpost 4 are both H Z The distance between the first living building doorpost 2 and the second living building doorpost 4 is L M , the thickness of the top floor 3 of the living building is H d , the width of the top floor 3 of the living building is L d , the length of the top floor 3 of the living building is L X .

[0047] The main structure of the living building is arranged at the stern 1 and is located behind the wind propulsion device; the main structure of the living building is door-shaped, and includes a first living building door column 2, a second living building door column 4 and a living building top floor 3, and the living building top floor 3 is arranged on the first living building door column 2 and the second living building door column 4;

[0048] The first living building doorpost 2, the second living building doorpost 4 and the living building top floor 3 are rounded to further reduce wind resistance;

[0049] In one embodiment, the wind propulsion device comprises at least two wind propulsion devices, and the two wind propulsion devices are symmetrically distributed;

[0050] The first living building doorpost 2 and the second living building doorpost 4 have a certain width. The first living building doorpost 2 and the second living building doorpost 4 are lengthened in the direction of the ship length to make up for the shortfall in width of the first living building doorpost 2 and the second living building doorpost 4.

[0051] The top floor 3 of the living building is the cockpit. Following the principle of optimal viewing angle, appropriate adjustments can be made in the direction of the ship's width, and the excess part in the direction of the ship's length can be used to make up other spaces.

[0052] The volume of available space in this living building is close to that of an ordinary living building;

[0053] In the direction of the ship's length, the first living building doorpost 2 and the second living building doorpost 4 are located right behind the wind propulsion device, so that the windward area is minimized.

[0054] In one embodiment, the wind propulsion device is arranged only on one side of the ship, so the doorpost on that side can be widened to a certain extent, and the width of the other doorpost can be reduced to a certain extent. The requirement is only to ensure the basic structural function and ultimately achieve the principle of minimizing the windward area while meeting the design specifications.

[0055] A gate-shaped accommodation block structure was designed to address the unique characteristics of wind-propelled vessel superstructures. The first and second accommodation block gateposts (2 and 4) are positioned approximately in line with the wind propulsion devices along the length of the vessel. The top floor (3) of the accommodation block is designed to optimize the pilot's perspective, minimize the superstructure's windward area within design specifications, and increase the length of the accommodation block along the length of the vessel to maintain the same usable space. This design significantly reduces wind resistance, addressing the increased wind resistance associated with the installation of numerous wind propulsion devices, reducing fuel consumption and carbon dioxide emissions, and promoting the optimized design and application of wind-propelled vessels.

[0056] Example 1

[0057] The ship is an 82,000-ton bulk carrier with six wind propulsion devices installed on its deck. The six wind propulsion devices are symmetrically distributed and are respectively the first wind propulsion device 5, the second wind propulsion device 6, the third wind propulsion device 7, the fourth wind propulsion device 8, the fifth wind propulsion device 9, and the sixth wind propulsion device 10. The width L1 of the first living building door column 2 and the width L2 of the second living building door column 4 are both 4.5 meters, and the heights of the first living building door column 2 and the second living building door column 4 are both H Z The distance between the first living building doorpost 2 and the second living building doorpost 4 is L M The thickness of the top floor of the living building is H d The width of the top floor of the living building is 4.5 meters. d The length of the top floor of the living building is 27 meters. X The first living building door column 2 and the second living building door column 4 are basically located completely behind the wind propulsion device in the direction of the ship's length.

[0058] like Figure 4 As shown, the flow field behind the wind propulsion device is significantly reduced in velocity. The first and second living quarters gateposts 2 and 4 located within this wake field significantly reduce wind resistance. When the ship is traveling at 14.1 knots, in a calm environment, the gate-shaped living quarters can reduce wind resistance by 16% compared to the original living quarters, increasing the design speed by 0.03 knots. In a wind speed of 12.4 m / s, the gate-shaped living quarters can reduce wind resistance by 19% compared to the original living quarters, increasing the design speed by 0.2 knots.
