Description

Technical Field

[0001] The present invention relates to the technical field of overall ship design, and particularly to a comprehensive layout method for typical cabins of an inward-tilting ship type based on the concept of framed hull structure protection. Background Art

[0002] The concept of framed structure protection has been widely applied in the structural design of new large ships abroad, that is, longitudinal box structures are adopted throughout the ship. Based on the comprehensive trade-off between protection efficiency and overall resource cost, the currently common application method of framed hull structures in ship design is to set longitudinal strong bulkheads in the main hull and integrated superstructure, as Figure 1 shown.

[0003] When arranging the overall cabins of traditional ships, it mainly focuses on important functional cabins, and forms an arrangement plan by connecting each main functional cabin through passages, lacking top-level consideration for structural protection performance. After adopting the Figure 1 structural design shown, it is required to minimize the openings on the longitudinal bulkheads to ensure the anti-explosion performance of the structure, which puts forward new requirements for the layout forms of the main channels and each functional cabin of the ship. And when large ships adopt the inward-tilting ship type, since the transverse width of each deck gradually decreases from bottom to top, when using longitudinal bulkheads, it is easy to have the problem that the sizes of the cabins on each deck are relatively small after being divided, lacking the layout of large-space cabin environments.

[0004] Therefore, it is urgent to analyze the above design conflicts and balance design elements such as protection, large-space layout requirements, cabin accessibility, and use convenience. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a comprehensive layout method for typical cabins of an inward-tilting ship type based on the framed protection concept to balance the structural protection performance, large-size space requirements, and cabin use convenience after the simultaneous application of the inward-tilting ship type and the framed protection concept in large ships. On the premise of ensuring the structural protection performance, large-scale functional cabins are planned and formed, and at the same time, a standardized main channel layout plan is constructed to ensure the rationality, neatness, and beauty of the overall cabin layout of the ship.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A comprehensive layout method for typical cabins of an inward-tilting ship type based on the framed protection concept, the basic design principles include:

[0008] a. Based on the framed protection concept, two longitudinal continuous bulkheads are arranged between each deck above the waterline on the left and right.

[0009] b. The longitudinal continuous bulkheads should cover the key protected cabins of the ship as much as possible.

[0010] c. The transverse positions of the longitudinal continuous bulkheads between decks should be as consistent as possible;

[0011] d. The longitudinal continuous bulkheads between decks should be part of the main passage on this deck;

[0012] e. In the main protection areas of the whole ship, the longitudinal continuous bulkheads should not be interrupted, and the number of personnel access openings should be minimized. Each deck is divided into a layout unit by two adjacent main transverse watertight bulkheads. The number of personnel access openings on each longitudinal continuous bulkhead within each layout unit should not be more than 2;

[0013] f. The main passage in the main hull should be located on the outside of the main functional cabins as much as possible, and the internal transverse passages within the layout units are used to achieve access connections;

[0014] Based on the above basic design principles, typical cabin layout methods for typical cabin sections in the main hull and the integrated superstructure are respectively formed, where:

[0015] S1. Standard layout method for typical cabin sections in the main hull, specifically including the following steps:

[0016] S1.1. Determine the position of the longitudinal main passage: The longitudinal main passage is arranged on the side, formed by the passage between the longitudinal continuous bulkhead and the side shell;

[0017] S1.2. Arrange typical functional cabins:

[0018] For large-sized functional cabins, the U2.0 layout is adopted. In the U2.0 layout form, the main passage formed by the longitudinal continuous bulkhead should not be directly connected to the large-sized functional cabin, but through a transverse passage. The inclined ladders leading to the upper and lower decks within this cabin section should be distributed at the two corners of the "U shape" as much as possible to form a dedicated area for personnel to cross floors;

[0019] For multiple functional cabins, the H2.0 layout is adopted. In the H2.0 layout form, the main passage formed by the longitudinal continuous bulkhead should not be directly connected to the functional cabin, but through a transverse passage. The connection between the transverse passage and the functional cabin is two-way, and the inclined ladders leading to the upper and lower decks are distributed in the middle of the "H shape" to form an independent stairwell;

[0020] S2. Standard layout method for typical cabin sections in the integrated superstructure, specifically including the following steps:

[0021] S2.1. Determine the position of the longitudinal main passage: A row of functional cabins should be arranged on the side of the superstructure, and the longitudinal main passage is arranged inside the side functional cabins;

[0022] S2.2. Arrangement of functional cabins in the superstructure: Adopt the II2.0 layout. In the II2.0 layout form, the longitudinal main passage can be directly connected to the functional cabins, and the connection between the longitudinal main passage and the functional cabins is two-way. A transverse passage can also be planned at the position where the upper and lower inclined ladders are concentrated.

[0023] In the above solution, in step S1.1, considering that the side space of the inboard ship type gradually decreases from bottom to top, sufficient space needs to be reserved for the side of the upper deck, and at the same time, the space of the main functional cabins should be ensured as much as possible. Based on the above principles, taking the left longitudinal main passage as an example, the method for determining its position is as follows: Offset the ceiling edge line on the left side of the midship of the top deck in the main hull inward by 1500 - 2500 mm as the initial position where the left longitudinal continuous bulkhead is located; The right longitudinal main passage is symmetrically arranged with the left longitudinal main passage.

[0024] In the above solution, in step S1.1, the position where the longitudinal continuous bulkhead is set should meet the structural strength requirements.

[0025] In the above solution, in step S1.1, the shape of the main passage at the pointed bow should be as consistent as possible with the bow deck edge line.

[0026] In the above solution, in step S1.2, based on the U2.0 layout, associated cabins can be nested in large - sized functional cabins without setting dedicated passages.

[0027] In the above solution, in step S1.2, based on the U2.0 layout, large - sized functional cabins can be arranged side by side horizontally with other functional cabins.

[0028] In the above solution, in step S1.2, based on the H2.0 layout, the longitudinal position of the transverse passage can be flexibly adjusted. Small - sized functional cabins are arranged on one side of the transverse passage, and large - sized functional cabins are arranged on the other side; The transverse passage can also be used to separate the flue from the cabins with intensive human activities to optimize the cabin environment.

[0029] In the above solution, in step S2.1, taking the left longitudinal main passage as an example, the method for determining its position is as follows: (1) Taking the top deck in the superstructure where a continuous longitudinal bulkhead is to be adopted as the reference, measure the half - width value B of the midship of this layer of deck; (2) The left longitudinal continuous bulkhead is taken 30% - 40% B from the ship center; (3) The width of the left main passage is taken as 1200 mm - 1500 mm; The right longitudinal main passage is symmetrically arranged with the left longitudinal main passage.

[0030] In the above solution, in step S2.2, based on the II2.0 layout, small - sized functional cabins are distributed along the side as much as possible, and large - sized functional cabins are arranged in the middle; Transverse bulkheads are used to realize the arrangement of entrances and exits across cabin sections.

[0031] In the above solution, in steps S1.1 and S2.1, the distance of the longitudinal continuous bulkhead from the ship's midship should preferably be an integer.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. The framework protection concept and the inwardly inclined ship form can effectively improve the protection performance and stealth performance of large ships, and at the same time bring new challenges to the overall layout design. The present invention proposes a design concept and specific design principles for the cabin layout of large ships applying the framework protection concept and the inwardly inclined ship form, and comprehensively forms a standardized method for cabin layout from multiple aspects such as structural protection, space utilization, planning of large-size functional cabins, cabin accessibility, and neat and beautiful layout, providing strong technical support for the agile design of the overall layout of future large ships.

[0034] 2. For the large-size functional cabins in the main hull of the present invention, the U2.0 layout is adopted, which can effectively increase the contact area between the main passage and the large-size functional cabins on the premise of ensuring the protection effect of the framework structure, thus facilitating personnel to frequently enter and exit the large-size cabins and improving the convenience of personnel flow; for multiple functional cabins in the main hull, the H2.0 layout is adopted, which can meet the needs of personnel to pass through and enter and exit multiple cabins both longitudinally and transversely on the premise of ensuring the protection effect of the framework structure, and improve the neatness of the cabin layout; for the functional cabins in the superstructure, the II2.0 layout is adopted, which can effectively improve the up-and-down passage efficiency and cabin space utilization rate in the superstructure on the premise of ensuring the protection effect of the framework structure.

[0035] 3. The comprehensive cabin layout method for the inwardly inclined ship form based on the framework protection concept proposed by the present invention can quickly construct the cabin layout plan of the whole ship in the conceptual design and scheme design stages, and has important practical value.

[0045] For a clearer understanding of the technical features, objectives, and effects of the present invention, the detailed implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0046] The present invention proposes a comprehensive layout method for typical cabins of an inward-tilting ship type based on the framework protection concept, which is as follows:

[0047] (1) Basic design criteria for cabin layout after applying the framework protection concept to the inward-tilting ship type

[0048] ① Main design concept

[0049] When designing the cabin layout, the structural protection performance and the realization of cabin functions are regarded as two key design objectives in parallel. On this basis, full attention is paid to the neatness of the cabin layout, and the consistency of the cabin layout in each cabin section is ensured as much as possible.

[0050] ② Basic design principles

[0051] a. Based on the framework protection concept, two longitudinal continuous bulkheads can be set between each deck above the waterline, one on the left and one on the right;

[0052] b. The longitudinal continuous bulkheads should cover the key protected cabins of the ship as much as possible;

[0053] c. The transverse positions of the longitudinal continuous bulkheads between each deck should be kept as consistent as possible;

[0054] d. The longitudinal continuous bulkheads between each deck should be part of the main passage on this deck;

[0055] e. In the main protected areas of the whole ship, the longitudinal continuous bulkheads should not be interrupted, and the number of personnel passage openings (greater than 650mm * 1650mm) should be minimized. Each deck is divided into a layout unit by two adjacent main transverse watertight bulkheads, and the number of personnel passage openings on each longitudinal continuous bulkhead in each layout unit should not be greater than 2;

[0056] f. The main passageway inside the main hull should be located as much as possible on the outside of the main functional compartments (referring to the side close to the ship's side), and the internal transverse passageways of the layout unit are used to achieve access and connection.

[0057] (2) Standard layout method for cabins in typical cabin sections inside the main hull of an inward-tilting ship type, specifically including the following steps:

[0058] ① Determine the position of the longitudinal main passageway.

[0059] The longitudinal main passageway is arranged on the ship's side and is formed by the passageway between the longitudinal continuous bulkhead and the ship's side outer plate. Considering that the side space of the inward-tilting ship type gradually decreases from bottom to top, sufficient space should be reserved for the side of the upper deck, and at the same time, the space of the main functional compartments should be ensured as much as possible. Based on the above principles, taking the longitudinal main passageway on the port side as an example, the method for determining its position is as follows:

[0060] a. Offset the ceiling edge line on the port side of the midship of the top deck inside the main hull by 1500 - 2500 mm towards the inside (referring to the side close to the ship's midship) as the initial position of the longitudinal continuous bulkhead 1 on the port side (see Figure 1 ).

[0061] b. On this basis, the distance of the longitudinal continuous bulkhead on the port side from the ship's midship should preferably be an integer.

[0062] c. The position where the longitudinal bulkhead is set should meet the requirements of structural strength.

[0063] d. The shape of the main passageway at the pointed and slender bow part should be kept as consistent as possible with the bow deck edge line.

[0064] ② Layout process for typical functional cabins.

[0065] a. For large-sized functional cabins, an improved "U-shaped" (hereinafter referred to as "U2.0 layout") is adopted. As Figure 2 shown, in the U2.0 layout form, the main passageway 3 formed by the longitudinal continuous bulkhead 2 should not be directly connected to the large-sized functional cabin 4, but is connected through the transverse passageway 5. The inclined ladders 6 leading to the upper and lower decks within this cabin section should be distributed as much as possible at the two corners of the "U-shape" to form a dedicated area for personnel to cross floors. On this basis, cabins associated with it can be nested and arranged in the large-sized functional cabin without a dedicated passageway. The large-sized functional cabin can also be arranged horizontally side by side with other functional cabins.

[0066] b. For multiple functional cabins, an improved "H-shaped" (hereinafter referred to as "H2.0 layout") is adopted. As Figure 3As shown in the figure, compared with the U2.0 layout, the basic idea of the H2.0 layout remains unchanged. The main difference is that the connection between the horizontal passage 5 and the functional compartment 7 is changed from one-way to two-way. The inclined ladders 6 leading to the upper and lower decks are distributed in the middle of the "H shape" to form an independent staircase, which is convenient for fire prevention, watertight and airtight control. On this basis, the longitudinal position of the horizontal passage can be flexibly adjusted. Small-sized compartments are arranged on one side of the horizontal passage, and larger-sized functional compartments are arranged on the other side. The horizontal passage can also be used to separate the flue from the compartments with intensive human activities (such as control or living compartments) to optimize the compartment environment.

[0067] (3) Standard layout method for typical cabin sections in an integrated superstructure

[0068] Integrated superstructures are widely used in large ships. The length of each deck in the superstructure is continuously increasing, and a continuous longitudinal bulkhead structure can also be adopted to improve the protection performance. Therefore, the following standard layout method for typical cabin sections is proposed:

[0069] ① Determine the position of the longitudinal main passage.

[0070] Different from the decks in the main hull, the space in the superstructure is more cramped, and side openings such as the intake and exhaust of power plants, ventilation shafts, and offshore replenishment operations need to be considered. Therefore, a row of functional compartments should be arranged on the side, and the longitudinal main passage should be arranged inside the side functional compartments; the position of the longitudinal bulkhead should be more towards the ship's center compared to the main hull. Based on the above principles, taking the left longitudinal main passage as an example, the method for determining its position is as follows:

[0071] a. Taking the top deck in the superstructure where a continuous longitudinal bulkhead is to be adopted as a reference, measure the half-width value B of the deck at the midship part.

[0072] b. The distance between the left longitudinal continuous bulkhead and the ship's center is 30% - 40% B, and an integer should be taken as much as possible.

[0073] c. The width of the left main passage is 1200mm - 1500mm.

[0074] ② Layout process of functional compartments in the superstructure.

[0075] Based on the improvement of the typical cabin section "II shape" layout form in traditional ships, the "II shape" standard layout form (hereinafter referred to as the "II2.0 layout") in the superstructure is formed. As Figure 4 shown in the figure, compared with the inside of the main hull, the superstructure emphasizes more on the accessibility between the upper and lower decks and has a lower demand for lateral accessibility. Therefore, the II2.0 layout form no longer emphasizes the necessity of setting up horizontal passages. The longitudinal main passage can be directly connected to the functional compartments, or a horizontal passage 5 can be planned at the position where the upper and lower inclined ladders 6 are concentrated.

[0076] The following takes a typical layout plan for a large ship that adopts the framework protection concept and an inward-tilting hull form and realizes functions such as dining, centralized control of equipment, and accommodation as an example. According to the above method, the method of the present invention will be described in detail.

[0077] (1) Implement the dining function by applying the U2.0 layout in the main hull

[0078] Refer to Figure 5 , arrange the dining hall by applying the U2.0 layout. Considering the large flow of people in the dining hall, set two entrances and exits. Nest the dishwashing room 8, elevator shaft 9, etc. in the dining hall. The longitudinal main passage realizes longitudinal passage across the watertight section, and the transverse passage realizes transverse, up-and-down layer and dining passage. At the same time, the continuity of the longitudinal bulkhead is ensured to the greatest extent.

[0079] (2) Implement the centralized control function by applying the H2.0 layout in the main hull

[0080] Refer to Figure 6 , arrange the electrical and mechanical centralized control room 10 by applying the H2.0 layout. The electrical and mechanical centralized control room 10 is generally arranged on the upper layer of the engine room, near the flue. The transverse passage 5 can be used to separate the two to optimize the cabin environment. Other cabins such as the machine repair room 11 and the battery room 12 are also arranged around the centralized control room. The longitudinal main passage 3 realizes longitudinal passage across the watertight section, and the transverse passage 5 realizes transverse and up-and-down layer passage. The position of the up-and-down inclined ladder 6 is adjusted according to the layout of the upper deck, which is different from the H2.0 standard form, but the principle remains the same. The continuity of the longitudinal bulkhead is still ensured to the greatest extent.

[0081] (3) Implement the accommodation function by applying the H2.0 layout in the main hull

[0082] Refer to Figure 7 , arrange the accommodation area by applying the H2.0 layout. There is also a flue in this cabin section. Few-person cabins such as the laundry room 13 and the bedding room 14 are arranged around it. The transverse passage 5 is used to separate the flue from the living cabin 15 to optimize the cabin environment. Functional cabins such as the toilet 16, washroom 17, and shower room 18 are arranged at both ends of the transverse passage. The whole cabin section forms a complete living community. The longitudinal main passage 3 realizes longitudinal passage across the watertight section and does not affect personnel activities. The transverse passage 5 realizes passage within the living community and up-and-down layers. The continuity of the longitudinal bulkhead is still ensured to the greatest extent.

[0083] (4) Implement the multi-functional layout by applying the II2.0 layout in the superstructure

[0084] Refer to Figure 8, the superstructure applies the II2.0 layout to arrange cabins such as living cabins 19, meeting rooms 20, shore power control rooms 21, air conditioner rooms 22, etc., to realize multiple functions. Among them, small-sized cabins such as living rooms, air conditioner rooms, and shore power control rooms are distributed along the side as much as possible, leaving space for flue layout in the middle. The large meeting room is relatively large and is arranged in the middle. Since there is no requirement for watertight bulkheads, the transverse bulkhead can be used to arrange entrances and exits across cabin sections. According to the layout requirements, the upper and lower inclined ladders can be arranged on the outer layer of the longitudinal passage or in the transverse passage. The longitudinal main passage 3 realizes longitudinal passage across cabin sections, and the transverse passage 5 realizes transverse and upper and lower layer passage. Only one access opening is provided in the longitudinal bulkhead between two cabin sections, and the continuity is ensured to the greatest extent.

[0085] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the purpose of the present invention and the scope protected by the claims. All of these are within the protection scope of the present invention.
