Description

Technical Field

[0001] This invention relates to the field of ship design and manufacturing technology, and in particular to a standardized design method applicable to the triangular area of ​​cabins in large cruise ships. Background Technology

[0002] Large cruise ships are hailed as "floating cities," with complex internal structures, numerous systems, and extremely compact space utilization. The cabin triangle (hereinafter referred to as the "triangle"), a typical and crucial functional area on a cruise ship, refers to the area enclosed by one or two cabin sanitary units through structural or bulkhead panels. It is used for the centralized arrangement and maintenance of various pipes (such as hot and cold water supply pipes, toilet water supply pipes, sewage pipes, fire-fighting pipes, and other system passage pipes), electrical equipment (such as cabin power supply equipment, cables, lighting, signals, switches, etc.), and fire-fighting supplies (such as fire hoses, fire nozzles, fire extinguishers, and hose supports). This area is the convergence point of the cabin's functional "nerve center" and "vascular network," and must be easily accessible for operation or maintenance when needed. Although the industry generally refers to it as the "triangle," its actual shape is often limited by the overall layout and space utilization, and it often presents as a triangle, rectangle, trapezoid, or more complex irregular space.

[0003] Currently, in the design and construction of large cruise ships, the design of the triangular area generally adopts a traditional, discipline-oriented, sequential design model. Its typical process is: "Design input → independent design by each discipline (piping, electrical, fire protection, interior design, etc.) → separate drawings by each discipline." This model has the following inherent defects and technical problems that urgently need to be solved:

[0004] 1. Lack of Design Standards and High Degree of Arbitrariness in Design Schemes: The industry lacks a unified, clear, and enforceable design standard and layout principle for similar triangular areas (e.g., those serving crew members or passengers of the same class). Designers primarily rely on personal experience for the spatial arrangement of outfitting components, resulting in vastly different final design schemes even for triangular areas with similar area, number of outfitting components, and specifications. Each triangular area is essentially a "unique" design product, making the design work inefficient, repetitive, and inconsistent in design quality.

[0005] 2. Insufficient interdisciplinary collaboration and difficulties in drawing coordination: During the design process, different disciplines often operate independently, lacking effective and proactive collaboration mechanisms. When each discipline completes its own design and merges the drawings, serious spatial interference between outfitting components is frequently discovered. For example, pipes may block the access doors of electrical boxes, cable trays may conflict with fire protection pipes, and openings may overlap with structural reinforcements. These problems, discovered only later, necessitate repeated revisions and coordination of design drawings, significantly extending the design cycle and resulting in substantial waste of human and material resources.

[0006] 3. The disconnect between design and production hinders modern shipbuilding practices: Traditional designs result in sets of fragmented specialized drawings. On-site construction personnel need to comprehensively understand multiple drawings before positioning and installation, demanding high levels of technical expertise and being highly prone to errors. More importantly, this non-standardized design is completely incompatible with the advanced shipbuilding concepts of "unitization and modularization." Because each triangular component is unique, mass prefabrication and production are impossible, severely restricting construction efficiency and cost control.

[0007] 4. High life-cycle costs: In the long run, the non-standardized design poses significant challenges to the later operation and maintenance of cruise ships. Maintenance personnel need to deal with thousands of different component layouts, spend a lot of time familiarizing themselves with and locating fault points, and have poor spare parts interchangeability, all of which significantly increase the difficulty and cost of maintenance.

[0008] Although computer-aided design (CAD) and even 3D modeling tools are widely used in the shipbuilding industry, these tools themselves cannot automatically solve the problems of standardization and collaborative design. While some standard drawing libraries exist for specific equipment, there is a lack of a systematic, multi-disciplinary, standardized design methodology that allows for free and non-interfering combinations to fundamentally resolve the chaotic situation in the design of the cabin triangle area of ​​large cruise ships.

[0009] Therefore, there is an urgent need in this field for an innovative design method that can break down professional barriers, achieve design standardization, eliminate interference from the source, and support modular construction. Summary of the Invention

[0010] In view of the above-mentioned problems existing in the prior art, the present invention provides a standardized design method applicable to the triangular area of ​​large cruise ship cabins. By establishing a systematic standard design node library covering multiple disciplines, the standardized and modular design and combination of outfitting components can be realized, thereby improving design efficiency and quality, avoiding interference between disciplines, supporting unitized batch construction, and reducing the total life cycle cost.

[0021] Preferably, the standardized nodes for deck openings are subdivided and named according to the location, number, size, and pipe material properties of the openings.

[0022] Preferably, in step S300, the generated drawing number includes the cabin type, piping node sequence number, pipe material attribute code, and a code for identifying whether fire-fighting miscellaneous parts are included.

[0023] Preferably, the standardized area node diagram includes the maximum installation range dimension (max) and minimum installation range or spacing dimension (min) of all outfitting components, with the deck surface as the base point for all dimensions.

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0044] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0045] This invention provides a standardized design method applicable to the triangular area of ​​cabins in large cruise ships, such as... Figures 1 to 9 As shown, it includes the following steps:

[0046] S100: Node acquisition steps: acquire the design nodes of each outfitting discipline, and select the design nodes applicable to the cabin triangle area;

[0047] S200: Node diagram compilation steps: Based on the selected design nodes, compile standardized area node diagrams for piping, electrical, fire protection components, and deck openings respectively;

[0048] S300: Node library construction steps: Select and combine the standardized area node diagrams according to the cabin type, triangular area area and outfitting quantity to establish a standardized design node library for the triangular area;

[0049] S400: Standardized drawing steps, based on the standardized design node library of the triangular area, to perform standardized drawing of the cabin triangular area.

[0050] Step S300 includes:

[0051] S301: Determine the cabin type;

[0052] S302: Select standardized piping system nodes;

[0053] S303: Select electrical standardization nodes;

[0054] S304: Select standardized nodes for deck openings;

[0055] S305: Select whether to adopt standardized fire protection components nodes based on requirements;

[0056] S306: Combine the selected professional nodes and generate drawing numbers to construct the standardized design node library for the triangular area.

[0057] The cabin types include standard crew cabins, passenger cabins, and senior crew cabins.

[0058] In this embodiment, the naming rules for the standardized piping nodes include cabin type codes and serial numbers used to distinguish piping system layouts; the naming rules for the standardized electrical nodes include cabin type codes, electrical specialty codes, and serial numbers used to distinguish electrical layouts; the naming rules for the standardized fire protection components nodes include cabin type codes and fire protection specialty codes; and the naming rules for the standardized deck opening nodes include cabin type codes, piping node serial numbers, opening location serial numbers, and codes used to identify pipe material properties.

[0059] In step S306, the drawing number includes a cabin type code, a piping node sequence number, and a code indicating whether fire-fighting components are included. The standardized area node drawing indicates the installation dimensions of each outfitting component, including the maximum installation range and the minimum installation range or spacing. The base point for all installation dimensions is the deck surface.

[0060] This invention aims to achieve modular construction of triangular areas through standardized design → formation of standardized areas → construction of standardized units → implementation of standardized drawings → realization of modular construction of triangular areas. Taking piping layout, electrical layout, fire protection miscellaneous component layout, and triangular area openings as the starting points, it establishes a node library for the comprehensive layout of outfitting components in triangular areas. Designers can select the standardized designs of the above four aspects according to the type of triangular area, and freely combine them to form standardized units, thereby efficiently modeling and standardizing drawings, enabling on-site construction personnel to carry out batch modular construction.

[0061] To facilitate understanding of the above technical solutions, a detailed explanation is provided below with reference to the accompanying drawings and specific examples: (Refer to...) Figure 1 The implementation process of this invention is as follows:

[0062] First, execute S100 to obtain all design nodes of various outfitting specialties of large cruise ships, select design nodes applicable to the cabin triangle area, and collect and filter design nodes applicable to various outfitting specialties (piping, electrical, fire protection, and structure) of the cruise ship cabin triangle area.

[0063] Next, S200 is executed. Under the premise of meeting the design constraints of each outfitting component, standardized area node diagrams for piping, electrical, fire protection components, and triangular area openings are prepared based on various different designs of the same outfitting components in the cabin triangle area. Standardized node diagrams are prepared for each specialty. For example, for the piping system of Class A (ordinary crew) cabins, multiple standardized layout node diagrams can be prepared, such as A1 (including fire hydrants and grey water pipes), A2 (including grey water pipes only), and A3 (including grey water pipes and transit pipes). Figure 3 (As shown). Electrical nodes can be programmed as AE1, AE2, etc. (e.g.) Figure 4 (As shown). Firefighting miscellaneous component nodes can be programmed as AF, BF, CF, etc. (e.g.) Figure 5 As shown). Deck opening details can be programmed as A1A, A1a, etc. (e.g.) Figure 7 (As shown).

[0064] Among them, such as Figures 3 to 7 As shown,

[0065] Piping Standardization Nodes

[0066] Type A1 Layout: This layout is designed for cabins located in a triangular area above liquid tanks (water or oil tanks, etc.). Due to its specific location, it's impossible to make through-hole openings on the deck. To facilitate the discharge of greywater (wastewater from washing and showering), a vacuum device is used to discharge the greywater through pipe 2 when gravity discharge to the lower deck is not possible. The vacuum pump hose is connected in method 1. To meet the ship's overall fire protection system layout requirements, fire hydrants may be installed in some triangular areas of this type. Their height from the deck surface is a fixed value, and the upper surface of the flange cannot exceed the MIN size of the electrical equipment protection box and the cable entry space. The locations of the vacuum pump, fire hydrants, and fire-fighting equipment are all fixed-size nodes, and there will be no interference between the three.

[0067] Types A2, A3, and A4 layouts are applicable to the triangular layout of crew quarters in non-liquid tank areas. The difference lies in the number of piping outfitting components and the medium in the piping system. For example, if A2 has only one grey water discharge pipe (pipe 1) and this pipe leads to the end user on this deck, it is not necessary to extend through the tank to the upper deck for grey water collection. The grey water discharge component (pipe 1) is a standard part with a fixed height. Similarly, the height of the discharge pipe component will not exceed the MIN size of the electrical equipment protection box. The grey water hose connection method is Method 2.

[0068] A3 has one more fire-fighting pipe than A2, and A4 has one more pipe passing through the passageway than A2. The opening positions of A2, A3, and A4 are all covered in the opening node of the triangular area, including changes in the relative passage position.

[0069] exist Figure 3 In this document, the four nodes represent only a portion of the technical solutions for this room type, and not all of the design and layout nodes.

[0070] Electrical Standardization Node

[0071] AE1 and AE2 types are arranged in two ways; the difference between them lies in the number of electrical equipment protection boxes. MAX represents the maximum height of the electrical equipment protection box installation (generally not allowed to exceed the height of the top door frame of the triangular access door), and MIN is the minimum spacing or height of the protection boxes. The minimum dimension between electrical boxes depends on the minimum bending radius of the cable, and it is based on the lower electrical box. The design height of the bottom electrical box is based on the deck surface. Vacuum pumps, fire hydrants, grey water collection components, and fire-fighting miscellaneous items are all arranged in the area below the electrical box, and the overhead pipes are located on both sides of the electrical box.

[0072] BE2 type layout: The number and size of electrical boxes vary depending on the room type or the type of electrical equipment required, but the size requirements are the same as those for AE1 and AE2 types.

[0073] Standardization Nodes for Fire Protection Miscellaneous Components

[0074] AF, BF, and CF nodes represent the triangular areas where fire hydrants need to be installed. Different nodes are selected depending on the room type. The image below shows the front view, and the top view will impose secondary restrictions on their placement.

[0075] Triangular region opening node

[0076] Triangular area openings; the selection of opening locations is subject to many constraints. Taking the triangular area of ​​a Type A crew living quarters as an example, the opening location is limited by the area of ​​the triangular area, the reinforcement of the deck reverse structure, the size and number of openings for through-cabin parts, the minimum weld spacing requirements, etc. There may be multiple opening designs for the same type of triangular area.

[0077] Then, execute S300 to build a node library. Based on cabin type, triangular area area, and number of outfitting components, select the appropriate nodes for each of the four types mentioned above, and compile a standardized triangular area design node library to form standardized triangular area units. Take the design of a Class A cabin triangular area as an example:

[0078] S301: The room type is determined to be A. Due to the large number of embodiments, this invention only selects Class A ordinary crew cabins for detailed description.

[0079] S302: Select pipe system nodes according to actual pipeline requirements. Only 3 layout designs are listed here. You can add or delete them as needed, such as A1.

[0080] S303: Select electrical nodes according to electrical requirements. Only three layout designs are listed here, and can be added or deleted as needed, such as AE1.

[0081] S304: Select the deck opening node according to the opening requirements. Only 4 opening designs are listed here (metal pipe A1A, A1B, plastic pipe A1a, A1b), which can be added or deleted according to actual needs.

[0082] S305: Determine whether fire-fighting accessories are needed. Since fire-fighting accessories are not required in every cabin triangle area, and can be flexibly adjusted according to actual working conditions during on-site construction, the three cabin types only form a standardized arrangement node for the triangle areas that require fire-fighting accessories. That is, for Class A cabins, only the A1 type piping node in the triangle area needs to be equipped with fire-fighting accessories. Therefore, only the triangle area corresponding to the A1 type piping system selects the AF fire-fighting accessory standardized node. The triangle areas corresponding to the A2 and A3 type piping systems directly skip this node. In this example, it is required, so the AF node is selected.

[0083] S306: Combine the selected nodes (A1, AE1, A1A, AF) to generate a unique drawing number for the triangular area. That is, combine the selected standardized nodes sequentially to generate drawing numbers. For standardized nodes requiring fire-fighting components, add "F" (Fire Fighting) to the drawing number; otherwise, use only Arabic numerals. At this point, the standardized node library for the triangular area is complete. When selecting drawings with corresponding nodes, model balancing must be performed on the drawings to identify and eliminate interferences in advance, for example, A001F. Here, "A" represents the building type, "001" is the serial number, and "F" indicates the inclusion of fire-fighting components. This step forms a standardized design unit.

[0084] Finally, S400 is executed, and standardized construction drawings are output based on the node library. These drawings clearly indicate the precise location, dimensional relationships, and selection of each outfitting component, allowing on-site construction personnel to carry out precise and efficient modular construction.

[0085] Standardized drawing output and modular construction

[0086] By integrating suitable nodes from different disciplines within the same type of triangular area, a standardized node catalog is formed. The drawings clearly express the relative positions of each outfitting component within this triangular area, the node selection, and the required outfitting component list.

[0087] Figure 9 In the standard node diagram (taking only the layout of drawing A001F as an example).

[0088] To facilitate differentiation of the layout differences (S200) of similar triangular areas across different specialties, the following supplementary explanation is provided based on the outfitting specialty:

[0089] (I) Standardized layout of piping system:

[0090] The piping system within the triangle area is complex and can be further subdivided based on the layout of one or more piping systems within the triangle area. For example, A1 is used to indicate the presence of fire hydrants and grey water pipes, A2 is used to indicate the presence of only grey water pipes, A3 is used to distinguish the presence of grey water pipes and crossing pipes, and so on. Passengers are represented by B1, B2, etc., and senior crew members are represented by C1, C2, etc.

[0091] (II) Standardized Electrical Layout:

[0092] The cruise ship's triangular area is equipped with electrical equipment protection boxes. Depending on the cabin type and function, the number, height, size, wiring method, and cable tray size of the electrical boxes vary. Therefore, the electrical standardization design nodes can be named AE1, AE2...BE1, BE2...CE1, CE2... etc., depending on the cabin type.

[0093] (III) Standardized Layout of Firefighting Equipment:

[0094] Firefighting miscellaneous items do not need to be arranged in every triangular area. Due to their sporadic nature, a set of standard arrangement nodes (which can be represented by AF, BF, and CF) can be formed according to the three major room types to clearly define the design modeling and on-site construction.

[0095] (iv) Opening in the triangular area:

[0096] Due to differences in structural layout, the location and number of openings in the same type of triangular area are not unique. When compiling a standardized opening diagram, standardized opening nodes can be formed based on the relative positions of the openings (A1A, A1B... for metal pipes, A1a, A1b...B1a... etc. for plastic pipes).

[0097] As can be seen from the above technical solutions, the standardized design method for the cabin triangle area of ​​large cruise ships provided by the above embodiments of the present invention establishes a design node library. The arrangement of outfitting components can be freely combined according to actual needs, maximizing design reuse. Several types of arrangements can cover the cabin triangle area design of the entire ship or even similar ships, which can greatly reduce the workload of designers and shorten the design cycle. Standardized design reduces the complexity and difficulty of on-site construction, and the installation process is also simpler and faster, which can effectively improve construction efficiency and accuracy, shortening the design and construction cycle of the triangle area by more than 80%. With the continuous rise in labor costs, reducing on-site workload can significantly reduce the installation cost of the cabin triangle area. Standardized design makes the product's parts universal, reducing the difficulty and cost of maintenance and replacement, and improving the maintainability of the product.

[0098] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
