Description

Technical Field

[0001] This invention belongs to the field of shipbuilding and design, and specifically relates to a ship that uses the same type of bulkhead in both the transverse and longitudinal directions. Background Technology

[0002] Currently, small and medium-sized oil tankers are equipped with trough-shaped bulkheads. These bulkheads are arranged alternately in the middle and middle of the tanker. The longitudinally arranged bulkheads are used to separate the port and starboard cargo holds, while the transversely arranged bulkheads are used to separate the fore and aft cargo holds.

[0003] The trough-shaped bulkhead consists of a bulkhead web and bulkhead panels. The bulkhead panels follow a horizontal straight line, while the bulkhead web follows a diagonal straight line. The piers consist of pier panels, pier side plates, and pier frames. Piers are installed at both the top and bottom of the trough-shaped bulkhead. The trough-shaped bulkhead is welded to one surface of the pier panel. A positioning reinforcement structure needs to be welded to the other surface of the pier panel, at a position corresponding to the trough-shaped bulkhead web. Without this positioning reinforcement structure, the load transmitted from the trough-shaped bulkhead to the pier panel will create stress concentration at the contact surface, potentially damaging the pier panel. Therefore, the positioning reinforcement structure of the trough-shaped bulkhead is crucial and indispensable.

[0004] Trough-shaped bulkheads are typically vertical trough-shaped bulkheads distributed along the length of the ship. Both the top and bottom of the trough-shaped bulkheads are equipped with piers to support them. Trough-shaped bulkheads arranged transversely have transverse piers, while those arranged longitudinally have longitudinal piers. The transverse and longitudinal piers have the same structure. At the intersection of transverse and longitudinal trough-shaped bulkheads, the transverse and longitudinal piers also intersect. Generally, the longitudinal piers are continuous, while the transverse piers are discontinuous.

[0005] Once the cargo density and loading height are determined, the width of the bulkhead panels and the bulkhead web can be determined. However, in the arrangement of trough-shaped bulkheads, interference may occur between the bulkhead web and the pier frame. Specifically, the installation positions of the alignment reinforcement structure and the pier frame may overlap, resulting in situations where the pier frame is installed but the alignment reinforcement structure cannot be installed, or vice versa. Current methods typically address this by adjusting the trough-shaped arrangement, creating an irregular trough-shaped arrangement, or adding additional frames.

[0006] In conventional ship types, the longitudinal and transverse channels cannot be unified and are often two completely different channels. Under the unified liquid cargo pressure, one of the channels will inevitably be wasted, and two or more sets of molds need to be made to manufacture the channel, resulting in waste. Summary of the Invention

[0007] To solve the above problems, the present invention provides a ship with corrugated bulkheads of the same corrugation type adopted in both transverse and longitudinal directions, which aims to achieve the purpose that corrugated bulkheads with the same corrugation type are adopted in both transverse and longitudinal directions and structural waste is avoided, and the technical solution adopted is:

[0008] A ship with corrugated bulkheads of the same corrugation type adopted in both transverse and longitudinal directions is provided. In the cargo hold area of the ship body, there are transversely and longitudinally staggered corrugated bulkheads. The transversely arranged corrugated bulkheads intersect with the longitudinally arranged corrugated bulkheads to form a plurality of independent cargo holds. The corrugated bulkhead is formed by connecting a plurality of corrugated members, and the opening directions of two adjacent corrugated members are opposite. The corrugated member is composed of one bulkhead face plate and two bulkhead webs, the bulkhead face plate is located between the two bulkhead webs, two corrugated members with opposite opening directions form a complete standard corrugation, and two intersection points B are formed at the junction of the bulkhead face plate and the bulkhead webs.

[0009] Bulkhead sills are respectively fixed at the top and bottom of the corrugated bulkhead, the bulkhead sill is provided with a horizontally arranged bulkhead sill face plate, the top and bottom of the corrugated bulkhead are respectively welded to one side of the bulkhead sill face plate, and a bulkhead sill frame and alignment reinforcing structures are arranged on the other side of the bulkhead sill face plate. The alignment reinforcing structures and the bulkhead webs are respectively located on both sides of the bulkhead sill face plate, and the installation position and direction of the alignment reinforcing structures correspond to those of the bulkhead webs.

[0010] The transversely arranged bulkhead sill face plate intersects with the longitudinally arranged bulkhead sill face plate to form four intersection points A, and any intersection point B in the longitudinally arranged corrugated bulkhead coincides with any intersection point A on the same side.

[0011] The corrugation type of the transversely arranged corrugated bulkhead plate is the same as that of the longitudinally arranged corrugated bulkhead plate, and the same corrugation type is the standard corrugation. The half corrugation length of the standard corrugation of the transversely arranged corrugated bulkhead is determined according to the maximum half-width dimension of the overall cargo hold, the longitudinal corrugated bulkhead plate is fixed according to the position of the transverse corrugated bulkhead plate, and the standard corrugation is finally determined. The unified standard corrugation is adopted for both the transversely arranged corrugated bulkhead and the longitudinally arranged corrugated bulkhead, and the specific implementation method is as follows:

[0012] S1: Determine the initial installation position of the transverse corrugated bulkhead in the transverse direction of the ship body

[0013] d=1000*D / k, where D is the known corrugation height and k=15;

[0014] When d≤1100mm, b1=200mm;

[0015] When 1100mm<d<1300mm, b1=250mm;

[0016] When d≥1300mm, b1=300mm;

[0017] Take the hull centerline +b1 as the starting position for installation of the transverse corrugated bulkhead plate, continuously arrange it toward both sides of the hull until reaching the inner shell of the hull side.

[0018] S2: Determine the standard half-groove length [M] of the corrugation

[0019] According to b f +t m <M<1.57d<2000mm, obtain the value range of the half-groove length M of the standard corrugation,

[0020] wherein, b f is the face plate length of the corrugated bulkhead plate;

[0021] t m is the horizontal web length of the corrugated bulkhead plate, 300mm<t m <600mm;

[0022] According to the value range of the standard half-groove length M, obtain the maximum value Mmax of the standard half-groove length and the minimum value Mmin of the standard half-groove length,

[0023] Calculate the value range of n1 according to Mmin and Mmax,

[0024] n1={(B-b1-100) / Mmin,(B-b1-100) / Mmax},

[0025] wherein, B is the known overall maximum half-width of the cargo hold;

[0026] n1 is rounded within the value range [n1]={n 11 ,n 11 +1…n 11 +n},

[0027] After n1 is rounded, the value of M is inversely calculated according to M=(B-b1) / [n1] to obtain [M]={M1,M2…M n}, [M] is the data obtained after rounding and zeroing {M1,M2…M n};

[0028] Finally, multiple sets of combinations of [M] and n1 are formed.

[0029] S3: Screen the standard half-groove length [M]

[0030] According to the multiple sets of combinations of [M] and n1 obtained in step S2, obtain the length b2 at the intersection of the transverse corrugated bulkhead face plate and the hull inner shell, b2=B-[M]*n1-b1,

[0031] when 100mm<b2<0.5b f , this set of combination of [M] and n1 is the data meeting the requirements, and all [M] meeting the requirements are screened out.

[0032] S4: Determine the number of half-slots in the standard slot pattern of the longitudinal slotted bulkhead.

[0033] n2=(L-n3*(d+a1-b f )-(d-0.5b f )*2) / [M],0.5b f <a1<800mm

[0034] Where a1 is approximately equal to 0.5d,

[0035] b f Approximately equal to d,

[0036] L is the overall length of the cargo hold.

[0037] n3 represents the number of transverse bulkheads.

[0038] n2 = (L - n3 * 0.5 * dd) / [M]

[0039] n2={n 21 ,n 22 …n 2n},

[0040] For n2, take an integer [n2]. When n2 - [n2] < 0.2, [n2] meets the requirement. [n2] is used as the number of half slots of the standard slot of the longitudinal slot bulkhead. The [M] corresponding to the [n2] that meets the requirement is used as the half slot length of the standard slot.

[0041] S5: Determine the panel b of the trough-shaped bulkhead. f and trough-shaped bulkhead web t m The standard groove type was finally determined by the value of the angle α formed by the web and the face plate.

[0042] L1 = M*n4 + d + a1 - b f ,

[0043] n4 = [L1 / M];

[0044] L=M*(n2-1)+n3*(d+a1-b f )+(d-0.5b f )*2;

[0045] Where L is the known overall length of the cargo hold.

[0046] L1 is the known length of an independent cargo hold.

[0047] n4 is the number of standard semi-slots longitudinally arranged in an independent cargo hold. n4 = L1 / M rounded down. When 50mm ≤ b f -d,b f =d+50; when bf -d≤100mm, b f =d+100, for b f Round down to find a1;

[0048] According to M=b f +t m , t m =d / tan(a), find b f、 t m And angle a.

[0049] Furthermore, for the aforementioned type of ship that uses the same type of bulkhead in both the transverse and longitudinal directions, when the projection line of the bulkhead frame intersects with the projection line of the bulkhead web on the bulkhead panel, or when the length b3 of the shorter side of the panel is less than 150mm, a split type of bulkhead frame is adopted.

[0050] The aforementioned ship, which uses the same type of bulkhead in both the transverse and longitudinal directions, further includes a split bulkhead frame consisting of an upper frame and a lower frame. The upper frame is welded to the side plate of the bulkhead, and the lower frame is welded to the panel of the bulkhead. There is a gap between the upper frame and the lower frame. Both the upper frame and the lower frame are inclined relative to the side plate of the bulkhead. The inclination direction of the upper frame relative to the side plate of the bulkhead is opposite to the inclination direction of the lower frame relative to the side plate of the bulkhead.

[0051] In a further embodiment of the aforementioned ship that uses the same trough-shaped bulkheads in both the transverse and longitudinal directions, the longitudinally arranged trough-shaped bulkheads are continuously arranged along the centerline of the hull, starting from the first transversely arranged trough-shaped bulkhead at one end, until the last transversely arranged trough-shaped bulkhead at the other end.

[0052] In the aforementioned type of ship that uses the same groove-shaped bulkhead in both the transverse and longitudinal directions, the width of the bulkhead panel is the same as the depth of the groove-shaped component.

[0053] Furthermore, in the aforementioned type of ship that uses the same type of bulkhead in both the transverse and longitudinal directions, the bulkhead frame is provided with a circular through hole near the bulkhead panel.

[0054] The aforementioned ship, which uses the same type of bulkhead in both the transverse and longitudinal directions, further features multiple longitudinal ribs evenly spaced on the side plates of the bulkhead, with the longitudinal ribs arranged horizontally and having the same length as the side plates of the bulkhead.

[0055] Furthermore, in the aforementioned type of ship that uses the same type of bulkhead in both the transverse and longitudinal directions, a semi-circular through hole is provided on the surface of the upper frame at the contact point between the upper frame and the lower frame.

[0056] In the aforementioned type of ship that uses the same type of bulkhead in both the transverse and longitudinal directions, the joint between the upper frame and the lower frame is located at the first longitudinal rib counting from the pier panel.

[0057] Furthermore, in the aforementioned type of ship that uses the same type of bulkhead in both the transverse and longitudinal directions, the connection between the bulkhead frame and the longitudinal skeleton is made by using a rounded transition connection.

[0058] This invention selects the trough type based on the ship's beam and then further refines it based on the ship's length, ensuring that the longitudinal and transverse troughs are identical. Simultaneously, the longitudinal bulkhead panel is aligned with the intersection point of the longitudinal and transverse bulkhead piers, unifying the arrangement of all trough types in the cargo hold area. Furthermore, a combination of split and integral bulkhead frame designs supports the trough bulkheads. This patent unifies the type of trough bulkheads throughout the ship's cargo holds, uses a single construction mold to complete the pressing of all trough types, simplifies the construction process, reduces construction difficulty, matches longitudinal and transverse trough bulkhead forms, optimizes the load-bearing capacity of the hull beams, and reduces the empty ship's weight.

Detailed Implementation

[0065] The invention will be further described with reference to the accompanying drawings.

[0066] A ship with transverse and longitudinally coaxial trough-shaped bulkheads has trough-shaped bulkheads arranged alternately in the cargo hold area of ​​the hull. The transversely arranged trough-shaped bulkheads intersect with the longitudinally arranged trough-shaped bulkheads to form multiple independent cargo holds. The trough-shaped bulkheads are formed by connecting multiple trough-shaped components. The opening directions of two adjacent trough-shaped components are opposite. Each trough-shaped component consists of a bulkhead panel and two bulkhead webs. The bulkhead panel is located between the two bulkhead webs, and the bulkhead panel and the bulkhead webs form two intersection points B.

[0067] The top and bottom of the trough-shaped bulkhead are fixed with piers, and the piers have horizontally arranged pier panels. The top and bottom of the trough-shaped bulkhead are welded to one side of the pier panel, and the other side of the pier panel is provided with a pier frame and a positioning reinforcement structure. The positioning reinforcement structure and the bulkhead web are located on both sides of the pier panel, and the installation position and direction of the positioning reinforcement structure correspond to the installation position and direction of the bulkhead web.

[0068] The transversely arranged bulkhead panels intersect with the longitudinally arranged bulkhead panels to form four intersection points A. Any intersection point B in the longitudinally arranged trough-shaped bulkhead coincides with any intersection point A on the same side. This structure ensures that the trough-shaped configuration is identical within a single cargo hold, meaning that the cargo hold length is an integer multiple of the standard half-trough length.

[0069] The size of the fixed alignment reinforcement structure at the intersection point is half the size of the original alignment reinforcement structure, such as... Figure 4 As shown, the half-alignment reinforcement structure 9 is welded at the point of overlap away from the intersection. When the transversely arranged wall pier panel intersects with the longitudinally arranged wall pier panel, the transversely arranged wall pier panel divides the longitudinally arranged wall pier panel into two parts, which are represented by d and a1 respectively.

[0070] When the projection lines of the pier frame and the bulkhead web intersect on the bulkhead panel, or when the length b3 of the shorter side of the panel is less than 150mm, i.e., where the installation position of the alignment reinforcement structure conflicts with the installation position of the pier frame, a split-type pier frame is used. The split-type pier frame consists of an upper frame and a lower frame. The upper frame is welded to the pier side plate, and the lower frame is welded to the pier panel. There is a gap between the upper and lower frames. Both the upper and lower frames are inclined relative to the pier side plate, with the inclination direction of the upper frame opposite to that of the lower frame.

[0071] The upper frame is fixed to the side plate of the bulkhead, while the lower frame is fixed to the bulkhead panel. The installation position of the lower frame corresponds to the web plate of the bulkhead, thus serving as a repositioning reinforcement structure and preventing stress from the trough-shaped bulkhead acting on the bulkhead panel, which could damage the bulkhead panel structure. The upper and lower frames are installed in opposite directions. As can be seen from the top view, the upper and lower frames intersect in an "X" shape. Therefore, this solves the problem of not being able to install the repositioning reinforcement structure when the installation positions of the bulkhead frame and the repositioning reinforcement structure conflict.

[0072] The transversely arranged trough-shaped bulkhead panels have the same trough shape as the longitudinally arranged trough-shaped bulkhead panels. This identical trough shape constitutes a standard trough shape. First, the transverse trough-shaped bulkhead panels are fixed. Then, the longitudinal trough-shaped bulkhead panels are fixed according to their positions. The specific implementation method is as follows:

[0073] S1: Confirm the initial installation position of the transverse bulkhead. The transverse corrugated bulkhead is a bilaterally symmetric figure. In order to avoid the excessively small distance E between two adjacent outwardly protruding transverse grooves and longitudinal grooves forming a narrow space, as Figure 3 shown, E shall be greater than 700 mm.

[0074] Therefore, a length b1 shall be reserved at the start of the transversely arranged corrugated bulkhead, and d = 1000*18 / 15 = 1200 mm is calculated according to d = 1000*D / k.

[0075] wherein, D is the corrugation height, D = 18 m, k = 15.

[0076] The value of b1 is determined according to the value of d. Since 1100 mm < d = 1200 mm < 1300 mm, therefore, b1 = 250 mm.

[0077] Take hull center line + 250 mm as the initial installation position of the transverse corrugated bulkhead plate, continuously arrange towards both sides of the hull until reaching the inner shell of the hull side.

[0078] S2: Confirm the standard half-corrugation length M of corrugation

[0079] According to b f +t m < M < 1.57d < 2000 mm, the value range of the half-corrugation length M of the standard corrugation is obtained: 1500 mm < M < 1880 mm,

[0080] wherein, b f is the face plate length of the corrugated bulkhead plate;

[0081] t m is the horizontal web length of the corrugated bulkhead plate, b f > d, d = 1200 mm, 300 mm < t m < 600 mm; lower limit values are adopted for all, therefore, b f +t m > 1500 mm

[0082] According to the value range of the standard half-corrugation length M, the maximum value of the standard half-corrugation length Mmax = 1880 mm and the minimum value of the standard half-corrugation length Mmin = 1500 mm are obtained,

[0083] the value range of n1 is calculated according to Mmin and Mmax,

[0084] n1 = {(B-b1-100) / Mmin, (B-b1-100) / Mmax},

[0085] wherein, B is the maximum overall half-width of the cargo hold, B=19830mm, based on b1=250mm obtained in step S1, it is further calculated that 10.4<n1<12.9, that is n1={10.4, 12.9}, n1 is rounded within the value range to obtain [n1]={11,12},

[0086] after n1 is rounded, the value of M is inversely derived according to M=(B-b1) / [n1] to obtain [M]={1770, 1620}, and finally two groups of combinations of [M] and n1 are formed, which are [M]=1770, n1=11 and [M]=1620, n1=12.

[0087] S3: Screening the standard half-groove length [M]

[0088] according to the two groups of combinations of [M] and n1 obtained in step S2, the length b2 at the intersection of the transverse grooved bulkhead plate and the inner hull is obtained, where b2=B-[M]*n1-b1, and b2=110mm and b2=140mm are obtained respectively.

[0089] when 100mm<b2<0.5b f , the combination of [M] and n1 in this group is data meeting the requirements, and all [M] meeting the requirements are screened out.

[0090] S4: Determining the number of half grooves n2 of the standard groove of the longitudinal corrugated bulkhead plate is n2=[101.6,111.037], then [n2]=111,

[0091] n2=(L-n3*(d+a1-b f )-(d-0.5b f )*2) / [M], 0.5b f <a1<800mm

[0092] wherein, a1 is approximately equal to 0.5d,

[0093] b f is approximately equal to d,

[0094] L is the known overall length of the cargo hold, L=182.95m

[0095] n3 is the known number of transverse bulkheads, n3=6

[0096] n2=(L-n3*0.5*d-d) / [M],

[0097] n2={n 21 ,n 22 …n 2n ,

[0098] Taking an integer value [n2] from n2, when n2 - [n2] < 0.2, [n2] meets the requirement. [n2] is used as the number of half-slots of the standard longitudinal slot bulkhead. The [M] corresponding to the [n2] that meets the requirement is used as the half-slot length of the standard slot. Therefore, [n2] = 111 meets the requirement, and the [M] corresponding to [n2] = 111 is the half-slot length of the standard slot. [M] = 1620mm. If multiple standard half-slot lengths meet the requirement, or if no standard half-slot length meets the requirement, then the standard half-slot length corresponding to the minimum difference between n2 and [n2] is selected as the final data.

[0099] S5: Determine the panel b of the trough-shaped bulkhead. f and trough-shaped bulkhead web t m The standard groove type was finally determined by the value of the angle α formed by the web and the face plate.

[0100] L1 = [M]*n4 + d + a1 - b f ,

[0101] n4 = [L1 / [M]];

[0102] L=[M]*(n2-1)+n3*(d+a1-b f )+(d-0.5b f )*2;

[0103] Where L is the known overall length of the cargo hold, L = 182.95m.

[0104] L1 is the known length of the independent cargo hold, L1 = 29.760m.

[0105] n4 is the number of standard semi-slots longitudinally arranged in an independent cargo hold. n4 = L1 / [M] rounded down. When 50mm ≤ b f -d,b f =d+50; when b f -d≤100mm, b f =d+100, for b f Round down to find a1;

[0106] According to [M] = b f +t m , t m =d / tan(a), find b f、 t m And angle a.

[0107] Based on the above method, the following conclusion is derived:

[0108] n4=[L1 / [M]=29760 / 1620]=18;

[0109] L1 = [M]*n4 + d + a1 - b f =1620*18+1200+a1-b f =29760;

[0110] L=[M]*(n2-1)+n3*(d+a1-b f )+(d-0.5bf)*2=1620*110+6*6

[0111] 00+(1200-0.5b f )*2=182950;

[0112] The solution yields that the length of the panel bf of the trough-shaped bulkhead is 1250mm, and the horizontal length t of the web of the trough-shaped bulkhead is... m Length 370mm, a=arctan(d / t) m ) = 72.8°, b w =d / sina = 1256mm.
