Description

Technical Field

[0001] This invention belongs to the field of marine engineering construction technology, specifically relating to a method for dividing the aquaculture compartment area of ​​a large aquaculture vessel. Background Technology

[0002] With the further development of the deep-sea aquaculture industry, a new type of enclosed, mobile "shipborne aquaculture" vessel has emerged, achieving a breakthrough from zero to one in the global "shipborne aquaculture" model. This type of aquaculture facility integrates systems for fish fry loading, feed distribution, seawater circulation aquaculture, adult fish lifting, and finished product processing. The vessel features a double-hull structure from the bottom to the sides, side decks, and the central and transverse bulkheads. A tunnel-like compartment is located in the middle of the double bottom. The aquaculture compartments are symmetrically separated by the central and transverse bulkheads. Each compartment has a four-sided sloping funnel-shaped floor. Bent ramps are installed at the lower ends of the central and inner hull longitudinal walls. Vertical pier structures are located at the intersections of the longitudinal and transverse bulkheads. The entire aquaculture compartment is octagonal, the top side compartment structure is pentagonal, and a central passageway structure, also hexagonal, is located between the middle of the deck and the central longitudinal wall. Conventional segmentation methods cannot be directly referenced.

[0003] The aforementioned large-scale aquaculture vessels have complex structures and numerous small, enclosed spaces. The outfitting and piping systems for aquaculture, harvesting, and processing are fully integrated into the structure, making construction difficult, precision control challenging, and the construction period lengthy. How to precisely divide these aquaculture facilities into sections for rational utilization has become a pressing technical problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a method for dividing the aquaculture compartment area of ​​a large aquaculture vessel into sections, setting a reasonable section division method, making full use of the shipyard's equipment and facilities capabilities, improving the pre-outfitting rate of sections, increasing the utilization rate of the planar assembly line, reducing construction difficulty, improving construction accuracy, improving construction safety, and effectively shortening the ship construction cycle.

[0005] The technical solution adopted is as follows:

[0006] A method for dividing the aquaculture compartment area of ​​a large aquaculture vessel involves several steps, including circumferential seam division along the ship's length, transverse section division within the circumferential section, special area division, overall segment division, and typical segment weight calculation. The specific steps are as follows:

[0007] (1) Circumferential seam division along the ship's length: The seam should be divided according to the principle of flush seam opening. The length of the circumferential seam should not exceed 20m. The seam division position should avoid cutting the vertical pier structure of the hull, the double-hull transverse bulkhead structure, and the area where the double-bottom fish raft equipment is located.

[0008] (2) Sectional division within the ring section: Based on the structural characteristics of large aquaculture vessels, each ring section of the large aquaculture vessel is divided into three layers: upper, middle, and lower. The bottom layer is divided into the midship double bottom section, the port side bottom section, and the starboard side bottom section; the middle layer is divided into the midship longitudinal bulkhead section, the port transverse bulkhead section (if present in the ring section), the starboard transverse bulkhead section (if present in the ring section), the port side section, and the starboard side section; the upper layer is divided into the middle deck section, the port side deck section, and the starboard side deck section.

[0009] (3) Special area segmentation: Due to the contraction of the outer plate line at the bow and stern of the aquaculture cabin area of ​​large aquaculture vessels and its proximity to the bow or engine room area, the structural form is different from that of the parallel mid-body area, and the segmentation method within the ring section is also different; the segmentation principle is still to reduce the cutting of the wall pier structure or slope structure, avoid cutting into the area where the double-bottom fish raft equipment is located, and maximize the integrity of the cabin structure segmentation stage;

[0010] (4) Overall segment division: The middle double bottom segment and the middle longitudinal bulkhead segment are assembled into upper and lower sections, and the fore and aft ring segments are assembled into the middle bottom segment; the port side bottom segment, the port side segment and the port transverse bulkhead segment are assembled into upper and lower sections, and the fore and aft ring segments are assembled into the port bottom segment, with the starboard side being symmetrical; the port deck segment is assembled into the fore and aft ring segments longitudinally, forming the port deck segment; the middle deck segment and the starboard deck segment are assembled into port and starboard sections, and the fore and aft ring segments are assembled into the starboard midship deck segment;

[0011] (5) Typical section weight calculation: Based on the preliminary section size boundaries defined above, and in conjunction with the detailed design drawings, the weight of typical sections (selecting the heaviest ones) is calculated. The weight is calculated by multiplying the structural weight by a coefficient of 1.08. At the same time, the weight for outfitting is estimated. The overall section or section weight does not exceed the shipyard's equipment and facility capacity requirements. If it exceeds the requirements, the length of the ring section or the size of the overweight section within the ring section is adjusted appropriately to meet the requirements.

[0012] Furthermore, in step (1), the length of the ring segments should be as uniform as possible to reduce the variety of ring segment length specifications. The ring segment seams are divided symmetrically forward and backward, centered on the aquaculture tank located near the center of the ship, which is beneficial for design and construction.

[0013] Furthermore, in step (1), the circumferential seam position is designed to avoid cutting small components such as the elbow plate of the frame structure as much as possible, and a certain distance is left to avoid generating too many bulk components for assembly.

[0014] Furthermore, in step (1), considering that the outer plate of the first and last areas of the aquaculture cabin has a large linear shape, the length of the ring segment should not be too long, so as to reduce the construction difficulty of the curved outer plate of the first and last ring segments.

[0015] Furthermore, in step (1), considering that the aquaculture cabin is adjacent to the engine room at the stern and adjacent to the bow at the bow, a small number of aquaculture cabin structures at the stern and bow can be assigned to the engine room or bow area respectively, and divided into sections according to the platform of each layer of the bow of the engine room, so as to reduce the difficulty of constructing the aquaculture cabin section.

[0016] Furthermore, in step (2), the upper, middle and lower sections of the same cross section of the breeding cabin are kept at the same height in the vertical direction to avoid forming a stepped section division, which facilitates the control of the segment construction size and reduces the difficulty of overall assembly and docking.

[0017] Furthermore, in step (2), the location of the width-direction joint of the double-bottom section is selected as the intersection of the circumferential joint and the corner line of the aquaculture tank bottom plate, which can reduce the number of panels to be assembled in the aquaculture tank bottom plate; the location of the height-direction joint is selected at about 1200mm above the tunnel hull top plate platform, that is, the middle position between the second and third ribs above the tunnel hull top plate platform. This height makes it convenient for personnel to stand directly on the tunnel hull top plate platform to carry out construction work on the overall joint. This division method divides the tunnel area, the midship slope plate, and part of the extended area into the same section, which facilitates centralized control of the construction accuracy of key nodes of the hull structure.

[0018] Furthermore, in step (2), the remaining portion outside the double-bottom section is the port and starboard side bottom sections. These side bottom sections encompass the entire structure of the fish raft equipment area at the bottom of the aquaculture tank. During the construction of the side bottom sections, the fish raft equipment and corresponding inlet and outlet pipes must be pre-embedded and fully installed to avoid difficulties in later installation. The upper opening of the side bottom section is level with the middle double-bottom section, thus dividing the side bottom ramp plate and part of the extended area into the same section, facilitating centralized control of the construction accuracy of key nodes in the hull structure.

[0019] Furthermore, in step (2), the location of the midship longitudinal wall section's beam-direction seam is selected on the outer side of the midship vertical bulkhead structure, including a portion of the transverse bulkhead structure. Simultaneously, the midship vertical bulkhead is divided within the section, allowing the bulkhead structure to be welded to the longitudinal and transverse bulkheads and its own complete structure during the sectioning stage, reducing the overall assembly and docking work. The beam-direction seam location is also preferentially aligned with the edge seam of the midship double-bottom section, which is beneficial for the structural regularity of the overall section division. The midship longitudinal wall section is located above the midship double-bottom section, with its upper seam located approximately 600mm below the midship passage bottom plate. This allows for controllable deck section weight, and the height of the midship bulkhead section is selected according to the maximum dimension, maximizing the planar assembly line processing and manufacturing of the midship longitudinal wall structure, thus improving construction efficiency.

[0020] Furthermore, in step (2), the seam location of the side section is selected outside the vertical bulkhead on the side, as close as possible to the vertical bulkhead. The section includes a portion of the transverse bulkhead structure, while the vertical bulkhead on the side is divided within the section. This allows the bulkhead structure to be welded to the longitudinal and transverse bulkheads and its own complete structure during the sectioning stage, reducing the overall assembly and docking work. The side section is located above the bottom section, and its upper seam location is approximately 600mm below the bottom plate of the fixed side compartment, level with the middle longitudinal bulkhead section. This avoids cutting the fish fry inlet pipes. The height of the side section is selected according to the maximum size, which allows for maximum planar assembly line processing and fabrication of the side outer plate and inner shell longitudinal bulkhead structure, improving construction efficiency.

[0021] Furthermore, in step (2), the transverse bulkhead section is located between the side section and the intermediate longitudinal bulkhead section, forming a double-shell structure. This meets the requirements for assembly line construction of the bow and stern structures and expands the application scope of the assembly line.

[0022] Furthermore, in step (2), the entire transverse bulkhead is divided into surrounding sections, each participating in the segment fabrication in different sections. During the final assembly stage, only the butt joints are constructed, avoiding the structural adjustment difficulties and paint damage issues caused by the high alignment accuracy requirements of the corner joint structure. The upper opening of the transverse bulkhead section is level with the intermediate longitudinal bulkhead and the side sections, ensuring the regularity of the upper opening structure of the entire intermediate layer section.

[0023] Furthermore, in step (2), the locations of the seams in the beam direction of the intermediate deck section and the side deck section are selected at the deck corner lines to avoid creating corner plates within the sections. The dimensional elements in the beam direction of the sections can meet the requirements for the assembly of deck pieces along a planar production line. The seam at the lower end of the intermediate deck section is located below the bottom plate of the intermediate passage, ensuring that the structure surrounding the central passage is completely within the same section. The seam at the lower end of the side deck section is located below the bottom plate of the top side compartment, ensuring that the structure surrounding the top side compartment is completely within the same section. This division method facilitates centralized control of the construction accuracy of key nodes in the hull structure.

[0024] Furthermore, in step (4), the large aquaculture vessel has a longitudinal frame hull structure and adopts a two-ring longitudinal assembly construction method, which is conducive to reducing the docking work of the assemblies and can effectively shorten the dock cycle.

[0025] Furthermore, in step (5), the weight calculation of the overall section can be performed simultaneously during the section division process, so as to detect in advance whether the weight of the overall section exceeds the hoisting and transportation capacity of the shipyard's equipment and facilities and to adjust the section division in advance. The section size information should also meet the capacity requirements of the shipyard's equipment and facilities.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] 1. By rationally dividing the segments, the number of different segment lengths is reduced to the minimum. The segments are divided in a symmetrical manner, which facilitates the design work, production tire placement, and construction.

[0028] 2. By rationally dividing the structure into sections, the number of sections, including the tunnel structure, vertical pier structure, bottom side structure, top side structure, and central passageway structure, is reduced to the greatest extent possible. This maximizes the integrity of the compartment structure during the section fabrication stage, facilitates centralized control of the construction accuracy of key nodes in the hull structure, reduces the amount of construction work in the confined space of the final assembly, and improves construction safety.

[0029] 3. By dividing the equipment into reasonable sections, the cutting of the fish raft equipment at the section seams can be avoided, ensuring that the fish raft equipment and related pipelines are installed in the section stage.

[0030] 4. By dividing the components into reasonable sections, avoid cutting loose elbow plate components at the break points, thereby reducing the total number of loose components assembled. Attached Figure Description

Detailed Implementation

[0045] The accompanying drawings are for illustrative purposes only; to better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; terms such as "upper," "lower," "top," "bottom," "side," "outer," "horizontal," and "vertical," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention. For those skilled in the art, some well-known structures and their descriptions in the drawings may be omitted, and therefore should not be construed as limiting the invention.

[0046] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0047] The objective of this invention can be achieved through the following technical solutions:

[0048] A method for dividing the aquaculture compartment of a large aquaculture vessel into sections involves several steps, including circumferential seam division along the vessel's length, transverse section division within the circumferential section, special area division, overall section division, and weight calculation of typical sub-sections. The specific steps are as follows:

[0049] (1) Circumferential seam division along the ship's length:

[0050] The seam division should be based on the principle of flush joints, with each segment not exceeding 20m in length. The seam division should avoid cutting into the vertical bulkhead structure, double-hull transverse bulkhead structure, and the area where double-bottom fish rafts are located. The segment length should be as uniform as possible to reduce the variety of length specifications. The seam division should be symmetrically divided forward and backward, centered on the aquaculture tank near the midships, which is beneficial for design and construction. The seam location should avoid cutting into small components such as the frame structure's elbow plates, and a certain distance should be left to avoid generating too many loosely assembled components, such as… Figure 1 , Figure 2 As shown, X1 represents the segmental assembly seam, and X2 represents the segment / assembly joint seam. The circumferential seams are symmetrically arranged with the aquaculture tank corresponding to ring 05 as the center, and the ship is divided into 10 rings along its length. Considering the large outer plating of the aquaculture tank area, the length of the fore and stern rings should not be too long to reduce the difficulty of constructing the curved outer plating of the fore and stern rings.

[0051] Considering that the aquaculture compartment's stern area is adjacent to the engine room area Q1, and its bow area is adjacent to the bow area Q2, a small number of aquaculture compartment structures at the stern and bow can be appropriately incorporated into either the engine room area Q1 or the bow area Q2. These structures are then divided into sections along with the various platforms at the bow of the cabin. The aquaculture compartment's stern structure A1 is incorporated into the engine room area Q1 and further divided into sections along with the cabin area. The aquaculture compartment's bow structure A2 is incorporated into the bow area Q2 and further divided along with the bow area. See details below. Figure 3 , Figure 4 As shown, this reduces the difficulty of constructing the aquaculture compartment in sections.

[0052] The final segment lengths are categorized as 13200mm, 17670mm, 18940mm, and 19930mm. The numbers at a distance in each figure represent the lengths in the embodiments, in mm.

[0053] (2) Segmentation of the transverse cross section within the ring segment:

[0054] Based on the structural characteristics of large aquaculture vessels, each ring section is divided into three layers: upper, middle, and lower. The lower layer is divided into the midship double bottom section F5, the port side bottom section F4, and the starboard side bottom section F7; the middle layer is divided into the midship longitudinal bulkhead section F6, the port transverse bulkhead section F3 (if present within the ring), the starboard transverse bulkhead section F8 (if present within the ring), the port side section F2, and the starboard side section F9; the upper layer is divided into the middle deck section F11, the port side deck section F1, and the starboard side deck section F10. The segmentation within the transverse section is as follows: Figure 5 , Figure 6 As shown, the upper, middle, and lower sections within the same cross-section are kept at the same height to avoid forming a stepped section division, which facilitates the control of the dimensions of each section during construction and reduces the difficulty of assembly and connection of the final assembly.

[0055] The location of the width-direction seam in the double-bottom section F5 is selected as the intersection point F13 of the circumferential seam and the corner line of the aquaculture tank floor. The cloud line F14 circles the seam as the corner line of the aquaculture tank floor. For example... Figure 7 As shown, this reduces the number of panels required for the bottom plate of the aquaculture tank. The vertical joint is located approximately 1200mm above the top plate platform of the tunnel hull, specifically between the second and third reinforcing members above the platform. This height allows personnel to directly stand on the tunnel hull top plate platform to perform construction work on the overall joint. This division method places the tunnel area, the midship ramp plate, and part of the extended area within the same section, facilitating centralized control of the construction accuracy of key structural nodes. See [link / reference]. Figure 8 As shown.

[0056] The remaining portion outside the double bottom section F5 forms the port and starboard side bottom sections (port side bottom section F4, starboard side bottom section F7). These side bottom sections encompass the entire structure of the fish raft equipment area in the aquaculture tank bottom. The fish raft equipment area F15 on the port side aquaculture tank bottom plate is located within the port side bottom section F4, with symmetrical sections on the starboard side. Figure 7As shown. During the construction of the side bottom section, the fish raft equipment and corresponding inlet and outlet pipes need to be pre-embedded and fully installed to avoid difficulties in later installation. The upper opening of the side bottom section is level with the middle double bottom section, which allows the side bottom ramp plate and part of the extended area to be divided into the same section, facilitating centralized control of the construction precision of key nodes of the hull structure, such as... Figure 8 As shown.

[0057] The location of the midship longitudinal wall segment F6, in the beam direction, is selected as the outer side of the midship vertical wall pier structure J2, including a portion of the transverse wall structure J1. Simultaneously, the midship vertical wall pier is divided within the segment, allowing the wall pier structure to be welded to the longitudinal and transverse walls and its own complete structure during the segmentation stage. Figure 9 , Figure 10 As shown, this reduces the overall assembly and docking work. The position of the seam in the beam direction is prioritized to align with the edge seam of the intermediate double bottom section, which is beneficial for the structural regularity of the overall section division. The intermediate longitudinal bulkhead section is located above the intermediate double bottom section, with its upper seam located approximately 600mm below the bottom plate of the intermediate passageway. This also allows for controllable deck section weight. The height of the intermediate bulkhead section is selected according to the maximum dimension, enabling the longitudinal bulkhead structure to be manufactured using a planar assembly line, improving construction efficiency.

[0058] The seam location for the side section is chosen to be outside the vertical bulkhead, as close as possible to it. The section includes a portion of the transverse bulkhead structure J1, while the side vertical bulkhead J2 is placed inside the section. This allows the bulkhead structure to be welded to the longitudinal bulkhead structure J3, the transverse bulkhead, and its own complete structure during the sectioning stage, reducing the overall assembly and docking work. The side section is located above the bottom section, with its upper seam located approximately 600mm below the bottom plate of the fixed-side compartment, flush with the middle longitudinal bulkhead section. This avoids cutting the fish fry inlet pipes. The height of the side section is selected according to the maximum dimensions, maximizing the planar assembly line processing and fabrication of the side outer plating and inner hull longitudinal bulkhead structure, improving construction efficiency.

[0059] The transverse bulkhead section, located between the side sections and the intermediate longitudinal bulkhead section, is a double-hull structure. Its structural dimensions are rationally segmented and designed to meet the requirements of planar assembly line construction for both the fore and stern surfaces, thus expanding the application scope of the assembly line. The entire transverse bulkhead is divided by surrounding sections, with each section participating in its own fabrication. During the final assembly stage, only the butt joints are constructed, avoiding the structural adjustment difficulties and paint damage issues associated with the high precision requirements of corner joints. The upper opening of the transverse bulkhead section is flush with the intermediate longitudinal bulkhead and side sections, ensuring the structural regularity of the entire intermediate layer section's upper opening.

[0060] The beam-direction seams of the intermediate deck and side deck sections are selected at the deck corner lines to avoid creating corner plates within the sections. The beam-direction dimensions of the sections allow for assembly-line fabrication of the deck panels. The lower seam of the intermediate deck section is located below the bottom plate of the central passageway, ensuring the entire structure surrounding the central passageway is within the same section. Similarly, the lower seam of the side deck sections is located below the bottom plate of the top side compartment, ensuring the entire structure surrounding the top side compartment is within the same section. This division method facilitates centralized control of the construction precision of critical structural nodes. Figure 8 As shown.

[0061] (3) Special area segmentation:

[0062] Due to the contraction of the outer slabs and proximity to the bow or engine room area, the structural form of the aquaculture compartments on the fore and stern of large aquaculture vessels differs from that of the parallel mid-body area, and the segmentation method within the ring section also differs. The segmentation principle remains the same: to minimize cutting into the wall pier structure or side-bottom slope structure, avoid cutting into the area where the double-bottom fish raft equipment is located, and maximize the integrity of the compartment structure at each segment stage. The segmentation method at the stern is as follows: Figure 11 As shown, the ship is divided into the following sections: midship double bottom section F5, port side bottom section F4, starboard side bottom section F7, port side section F2, starboard side section F9, midship longitudinal bulkhead section F6, midship deck section F11, port side deck section F1, and starboard side deck section F10. The bow section is divided as follows: Figure 12 As shown, the structure is divided into the following sections: midship double bottom section F5, port side bottom section F4, starboard side bottom section F7, port inner hull longitudinal bulkhead section F16, starboard inner hull longitudinal bulkhead section F12, port side section F2, starboard side section F9, midship deck section F11, port side deck section F1, and starboard side deck section F10.

[0063] (4) Overall segmentation:

[0064] The large aquaculture vessel features a longitudinal frame hull structure, employing a two-ring longitudinal assembly method. This method reduces the need for dockwork and effectively shortens the docking period. The overall section division is as follows: The midship double bottom section F5 and the midship longitudinal bulkhead section F6 are assembled vertically, forming the midship bottom section; the port side bottom section F4, the port side side section F2, and the port transverse bulkhead section F3 are assembled vertically, forming the port bottom section, with symmetry on the starboard side; the port side deck section F1 is assembled longitudinally, forming the port deck section; the midship deck section F11 and the starboard side deck section F10 are assembled port and starboard, forming the starboard midship deck section. The overall section division and assembly method are as follows: Figure 13 As shown.

[0065] (5) Typical total weight calculation:

[0066] Based on the preliminary segment size boundaries defined by the above method, and in conjunction with the detailed design drawings, the weight of a typical segment (selecting the heaviest one) is calculated. The weight is calculated by multiplying the structural weight by a coefficient of 1.08. At the same time, the weight for outfitting is estimated. The overall segment or total segment weight does not exceed the shipyard's equipment and facility capacity requirements. If it exceeds the requirements, the length of the ring segment or the size of the overweight segment within the ring segment is adjusted appropriately to meet the requirements.

[0067] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
