Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a method for dividing module sections of a container ship. Background Art

[0002] Limited by the assembly and lifting capabilities of shipyard production lines, the method of building ship blocks has the following technical deficiencies: 1. Limited by the lifting capacity of the gantry cranes installed at the shipyard, the total section cannot be infinitely large, and the number of total sections divided into ships is too large; 2. Docks or slipways are core resources for shipbuilding. A high number of loading and lifting operations will affect the ship loading cycle, resulting in an excessively long dock or slipway loading cycle, thereby restricting the increase in the annual construction batches of the dock or slipway. 3. Low site utilization rate. The existing technology involves laying the entire section flat on the site for construction, making little use of the site's floor space. 4. Secondary outfitting is required during the assembly and loading stages, which results in low outfitting efficiency. At the same time, the original coating is damaged and needs to be re-coated, resulting in a waste of time and cost. Summary of the Invention

DETAILED DESCRIPTION

[0017] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0018] A preferred embodiment of the method for dividing module sections of a container ship of the present invention is as follows: Figures 1 to 6 As shown, the module block division method of the container ship includes the following steps: S1, according to the functional system of the container ship, the lifting capacity of the lifting system and the transfer capacity of the segmented support tooling 5, the container ship is divided into the engine room module section 1, the cargo hold module section 2, the bow module section 3 and the superstructure module section 4.

[0019] S2, based on the base being distributed in the same section as much as possible, the cabin module section 1 is divided into a front cabin section 11, a rear cabin section 12, a cabin cover section 13, and a rudder cover section 14.

[0020] S3, based on the length of a standard container, the cargo hold module section 2 is divided into a bottom section 21, a side section 22, and a transverse bulkhead section 23.

[0021] S4, based on the principle that the liquid tanks and thruster tanks are distributed in the same section as much as possible, the bow module section 3 is divided into a bow cabin lower ring section 31, a bow cabin upper ring section 32, a bow upper section 33, and a bow lower section 34 in a bilaterally symmetrical manner.

[0022] S5, based on the integrity of the compartment with independent functions, the upper construction module section 4 is divided into one or more sub-sections.

[0023] In step S1, within the container ship's functional system, engine room module section 1 is the container ship's power drive module, encompassing the area from the hull's stern plate to the engine room front wall (inclusive), 0.5 to 1.5 frames long. Cargo hold module section 2 is the container ship's load and ballast module, encompassing the area from the engine room front wall (excluding the engine room) to the transition point between the flat bottom line of the cargo hold, and the straight cargo hold area in the middle of the ship. Bow module section 3 is the container ship's steering assistance and anchoring module, encompassing the area from the transition point between the flat bottom line of the cargo hold to the bow column. Superstructure module section 4 is the container ship's accommodation module, encompassing the accommodation and funnel areas of the superstructure.

[0024] In step S1, after the lifting capacity of the lifting system is met, the weight of each module segment of the container ship does not exceed the lifting capacity of the shipyard. When the transfer capacity of the segment support fixture 5 is met, the total weight of each module segment does not exceed the sum of the lifting capacity of the lifting system and the transfer capacity of the segment support fixture 5.

[0025] In step S2, the cabin module section 1 is divided into sections, with the bases distributed as closely as possible. The main engine base is typically located in the forward cabin section 11, the intermediate bearing base in the aft cabin section 12, and the bases for small and medium-sized equipment such as auxiliary engines, pumps, and air cylinders in the cabin cover section 13. The principle is to ensure that each base can be installed completely as a whole. In this embodiment, the sections of the cabin module section 1 are spaced 10-16 meters apart along the fore-aft direction. If conditions permit, the sections can be divided into equal longitudinal sections.

[0026] In step S3, specifically, the cargo hold module section 2 is divided into a bottom section 21, a side section 22, and a transverse bulkhead section 23 based on the length of a 40GP standard container. The thickness of the transverse bulkhead design is taken into consideration during the division to ensure that the size of the sections can accommodate the corresponding containers, thereby reducing the specifications of the plates and profiles at the source.

[0027] In step S4, the bow cabin lower ring section 31, bow cabin upper ring section 32, bow upper subsection 33, and bow lower subsection 34 of the bow module block 3 are all within the shipyard's lifting capacity, facilitating the construction of the various sections of the bow module block 3. The bow module block 3 is divided into upper and lower sections, with the left and right structures of the bow module block 3 being essentially symmetrical. During the block construction process, the safety and stability of the block are ensured by the segment support fixtures 5. After the welding of the module segments is completed, a complete, symmetrical block with left and right structures is formed, ensuring the safe construction of the container ship.

[0028] In step S5, the superstructure module segment 4 is the container ship's accommodation module. The weight of the segment is determined by the shipyard's lifting capacity. If the lifting capacity is met, the superstructure module segment 4 is preferably divided into a single sub-segment. Alternatively, the superstructure module segment 4 can be divided into multiple sub-segments. When dividing the sub-segments, each cabin with an independent function is assigned to the same sub-module to ensure that each functional cabin is fully commissioned.

[0029] The module block division method of the container ship divides each module block according to the functional system, and increases the transfer capacity of the segment support tooling 5 on the basis of the lifting capacity of the lifting system, which can increase the weight of each module block and reduce the number of segments contained in each module block. The height of the segment is increased, which improves the site utilization efficiency and reduces the number of hoisting times and the loading cycle when loading the block, thereby shortening the construction cycle in the dock and improving the construction capacity of the dock and slipway. The number of loading times and the number of segment seams are reduced, and the workload of the later outfitting is reduced, which effectively shortens the ship construction cycle and improves the risk resistance to market fluctuations.

[0030] In some embodiments, in step S1, the engine room module section 1 is divided based on the power and energy system; the cargo hold module section 2 is divided based on the cargo and ship ballast adjustment function; the bow module section 3 is divided based on the bow thruster, anchoring and bow ballast function; and the superstructure module section 4 is divided based on the superstructure living and working cabins and chimney functional systems.

[0031] The power and energy system is the power drive module of the container ship, which matches the function of the engine room module section 1, and can reasonably ensure the integrity of the power drive structure; the cargo and ship ballast adjustment function is the functional core of the cargo hold module section 2, and this is used as a benchmark to ensure that the cargo hold module has a reasonable capacity; the bow thruster, anchoring and bow ballast functions are the core of the bow module section 3, and this is used as a benchmark to ensure the integrity of the container ship steering assistance and anchoring module; the superstructure module section 4 has many functional units, mainly based on the superstructure living and chimney areas. The superstructure living and working cabins and chimney functional systems are the functional core of the superstructure module section 4, which can ensure that each independent functional cabin is divided into the same module, and ensure that each functional cabin is fully debugged.

[0032] In some embodiments, in step S1, the container ship is further divided into a lashing bridge module section, which includes a plurality of lashing bridges. Taking each lashing bridge between two adjacent cabins as a reference, each lashing bridge is a lashing bridge section.

[0033] Lashing bridges are unique components on the deck of container ships. Generally, one is installed between every two cabins. Their structure and construction method are the same. Therefore, all lashing bridges are defined as lashing bridge module sections, and each lashing bridge is a section, which becomes the lashing and fixing module of the container ship.

[0034] Based on the shipyard's lifting capacity, each lashing bridge can be divided into left and right sections, or left, center, and right sections, according to its width. Each section is a submodule, and is placed in a straight-up position for loading, painting, and assembly. Ultimately, the ship is hoisted and loaded in an integrated manner, complete with outfitting, lighting, and painting. Upon completion, each lashing bridge is installed in corresponding positions, such as engine room module section 1, cargo hold module section 2, and bow module section 3, depending on its installation location.

[0035] In some embodiments, in step S2, the segmentation seams between the front engine room segment 11 and the rear engine room segment 12, and between the engine room cover segment 13 and the rudder cover segment 14 along the front and rear directions of the container ship are accurately determined by the main engine base and the intermediate bearing base, the segmentation seam between the front engine room segment 11 and the engine room cover segment 13 is accurately determined by the engine room second platform 6, and the segmentation seam between the rear engine room segment 12 and the rudder cover segment 14 is accurately determined by the auxiliary engine base platform 8.

[0036] In this embodiment, the front and rear divisions of the front engine room section 11 are from the front wall of the engine room (inclusive) 0.5 to 1.5 ribs to the stern to the main engine and the intermediate bearing base, and the upper and lower divisions are from the outer plate baseline to the position of the second engine room platform 6; the rear engine room section 12 is from the tail to the stern cover plate of the hull, and the upper and lower divisions are from the outer plate baseline to the auxiliary engine base platform 8, including the steering gear base; the front and rear divisions of the engine room upper cover section are from the front wall of the engine room (inclusive) 0.5 to 1.5 ribs to the stern to the main engine and the intermediate bearing base, and the upper and lower divisions are from the second engine room platform 6 to the main deck 7; the tail of the rudder upper cover section is from the stern cover plate of the hull, and the upper and lower divisions are from the auxiliary engine base platform 8 to the main deck 7, and the segment seams are the boundaries between the various sections.

[0037] In some embodiments, in step S2, the distance between the segmented seam and the main engine base, and the distance between the segmented seam and the intermediate bearing base ranges from 150 mm to 300 mm.

[0038] In this embodiment, the distance between the segmented seam and the main engine and bearing bases is maintained at 150mm-300mm, ensuring the integrity of large bases such as the main engine and intermediate bearing bases. Furthermore, the distance between the bases of small and medium-sized equipment such as auxiliary equipment, pumps, and air cylinders and the segmented seam is kept between 100mm and 200mm to ensure complete installation. If the equipment base straddles the segmented seam, slow installation is implemented.

[0039] In some embodiments, in step S2, when determining the segment seams of the front cabin segment 11, the rear cabin segment 12, the cabin upper cover segment 13, and the rudder upper cover segment 14, it is ensured that the bulkheads of a single tank compartment are in the same segment.

[0040] In this embodiment, each tank compartment is composed of six bulkheads forming a complete cubic compartment. Based on the position of the six bulkheads, and while meeting the aforementioned cabin segment division, the integrity of the tank compartment is guaranteed by ensuring that the six bulkheads of a single tank compartment are within the same cabin segment as much as possible. If there are too many tank compartments in a segment and the integrity of the tank compartment cannot be guaranteed, the aforementioned segment seam division shall be used as the priority.

[0041] In some embodiments, in step S3, the bottom segment 21, the side segment 22, and the transverse bulkhead segment 23 are all annular segments, and the size of the bottom segment 21, the side segment 22, and the transverse bulkhead segment 23 along the front and rear directions of the container ship ranges from 13 m to 16 m.

[0042] Annular segmentation facilitates the construction of various segments on a dock or slipway. When dividing the segments, the front and rear dimensions of the segments are preferably divided into equal lengths, which can reduce the specifications of plates and profiles.

[0043] In some embodiments, in step S4, the bow cabin lower ring section 31, the bow cabin upper ring section 32, the bow upper segment 33, and the bow lower segment 34 of the bow module section 3 are divided according to the upper and lower positions and the left and right structures are symmetrical. The bow cabin lower ring section 31 and the bow lower segment 34, and the bow cabin upper ring section 32 and the bow upper segment 33 are both accurately segmented along the front and rear directions with the bow transverse wall 9 at 0.5 to 1.5 ribs to the stern as the accurate segmentation seam, the bow cabin lower ring section 31 and the bow cabin upper ring section 32 are accurately segmented along the up and down directions with the middle platform 20 as the accurate segmentation seam, and the bow upper segment 33 and the bow lower segment 34 are accurately segmented along the up and down directions with the forepeak tank platform 10 as the accurate segmentation seam.

[0044] In this embodiment, the front and rear divisions of the bow cabin lower ring section 31 are located between the bow transverse wall 9 and the 0.5 to 1.5 ribs to the stern and the cargo hold module total section 2, and the upper and lower divisions are divided from the outer plate to the middle platform 20 area; the front and rear divisions of the bow cabin upper ring section 32 are consistent with the bow cabin lower ring section 31, and the upper and lower divisions are from the middle platform 20 to the main deck 7 area; the bow lower section 34 is divided front and rear from the bow transverse wall 9 to the bow, and the upper and lower divisions are from the baseline outer plate to the forepeak tank platform 10, which can ensure the integrity of the forepeak tank total section; the bow upper section 33 is divided front and rear in accordance with the bow lower section 34, and is divided up and down to the forecastle deck; the upper and lower half-ring segmentation divisions can take into account the construction stability and safety of each segment, as well as the integrity of the liquid tank and the thruster tank, and avoid the influence of the linear changes in the bow area of the container ship on each segment.

[0045] In some embodiments, in step S4, the size range of the bow lower ring section 31, the bow upper ring section 32, the bow upper segment 33, and the bow lower segment 34 along the front and rear directions of the container ship is 10m-15m.

[0046] The dimension of each segment in the front-to-back direction is between 10m and 15m, which can reduce the specifications of the plate and profile. In this embodiment, when conditions permit, it is preferred to ensure that each segment is divided into equal lengths in the longitudinal direction.

[0047] In some embodiments, in step S1, the segmented support tooling 5 is formed by a support base 51, a transfer bracket 52 and a transfer vehicle 53, the support base 51 is fixed on the top of the transfer bracket 52, the carrying load of the transfer bracket 52 is less than 85% of its design load, the transfer vehicle 53 is supported on the bottom of the transfer bracket 52, and the load of the transfer vehicle 53 is less than 80% of its design load.

[0048] The weight of each module segment greatly exceeds the lifting load capacity of the shipyard's gantry crane. Through the segmented support tooling 5, the construction and shaping of each module segment can be realized, as well as the transfer and closure loading on the ground. During the transfer and loading, the force analysis of each module segment is used to calculate the force load of the ship's piers and transfer support points, which serves as the basis for the setting of the piers and transfer support points.

[0049] In this embodiment, support base 51 serves as a support platform for the hull structure. Because the hull bottom structure transitions from a flat center portion to curved bow and stern sections, strong support fixtures are required at the bottom of the curve to extend the support points of the curved surface to align with the baseline. Together with the flat bottom structure, this forms the planar support system for the ship's bottom, which is the foundation for ground transport. The placement of support base 51 is determined by the layout of the ship's dock, and its load capacity should match the transport vehicle, typically 500 to 1,000 tons.

[0050] The transfer scaffolding 52 is a support device between the ship and the ground, used to bear the weight of the ship during static construction and transportation. Its function is similar to that of the docking piers, and it is integrated with the docking piers in the transfer route area to form the entire ship's support system. During the construction of each module assembly in the dock or slipway, the transfer scaffolding 52 is maintained at a height of 1.8 to 2.0 meters above the ground, depending on the height and lifting range of the transport vehicle, to facilitate the entry and exit of transport vehicles during the ship's transportation after completion.

[0051] The number of transfer brackets 52 to be arranged is determined based on the ship's calculations. The load of the transfer brackets 52 is less than 85% of their design load, and the load of the transfer vehicle 53 is less than 80% of its design load, which can ensure the safety of the transfer process. In this embodiment, the placement of the transfer brackets 52 should avoid the closure seams, drain plugs, and depth sounders. Generally, the distance from the closure seams should be no less than 300mm, and the distance from the drain plugs and depth sounders should be no less than 150mm. If the drain plugs and depth sounders cannot be avoided, they need to be raised and inspected. The transfer vehicles 53 are generally arranged in left and right partitions based on the stress analysis of the module segment and the overall weight matching.

[0052] In summary, an embodiment of the present invention provides a method for dividing module sections of a container ship, which divides each module section according to the functional system, and increases the transfer capacity of the segment support tooling on the basis of the lifting capacity of the lifting system, thereby increasing the weight of each module section and reducing the number of sections contained in each module section. The height of the sections is increased, which improves the site utilization efficiency and reduces the number of hoisting times and the loading cycle when loading the sections, thereby reducing the construction cycle in the dock and improving the construction capacity of the dock and slipway. The number of loading times and the number of segment seams are reduced, and the workload of the later outfitting is reduced, which effectively shortens the ship construction cycle and improves the risk resistance to market fluctuations.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
