Description

1373434 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a vessel equipped with one or more liquid transport tanks which are disposed on the hull of the vessel. [Prior Art] At present, the methods used to transport chemicals, oils and agricultural products mainly use tankers, which are equipped with rectangular cargo tanks, also known as tank tankers. The cargo tanks are part of the vessel structure. The tank walls are formed by the hull of the vessel, a plurality of decks placed on the bulkhead and longitudinal bulkheads, and the deck of the vessel. The disadvantage here is that cracks may occur in the walls of the tank due to the ship's turbulence and deformation due to temperature differences. The resulting high stress in the grooves (especially at the corners) can lead to the formation of cracks. If this happens, the hole can develop between the slots, which will allow mixing between the stored goods to occur. In the current rules, the regulations have been made for the transmission, that is, the adjacent tanks must be packed with the same goods to avoid the risk of cross-contamination and a dangerous situation can be dispensed with. The same cargo can be transported in such tanks, so the tanks must be carefully cleaned to ensure that a shipment to be transported is contaminated. However, these tanks are difficult to clean. The wall portions are partially shaped to be transported into the body, so that there are a plurality of tanks for transporting the liquid medium, wherein the deformation of the sea surface in the compartment is concentrated. It may be in the presence of many cargo items in two adjacent unpleasant phases, which will be because some of them are not cleaned after shipment and will not be separated because they have enough rigidity for the foot 1373434, and because the walls have many corners Interval. This means that a considerable amount of flushing water is needed for cleaning the tanks' and this would be expensive and environmentally undesirable because the flushing water must sometimes be discharged as chemical waste. In addition, a small amount of contamination remaining in the tank cannot always be detected by an inspection, which may result in damage that may occur on the subsequently transported goods. Therefore, a larger temperature difference may occur in the stored cargo. It is also necessary to heat to a higher temperature so that a desired temperature can be maintained in the tank. Degree may lead to the deterioration of the cargo. In this technique, the pursuit of an alternative has been carried out for a considerable period of time, for example, there is a mourning system in which many cylindrical storage tanks are placed in the ship. In the hull, for example, as in US-6,167,827 or DE-U-9 3.09.43 3. The vessel system described in the previous paragraph of the definition of the scope of claim 1 can be NL-C No. 1011836. This publication discloses a vessel 'which has a cylindrical transport trough placed in the hull of the ship. In this case, the bottom of the trough is supported on the hull of the ship, and Attached to a peripheral wall of a cylindrical groove, a spring device is disposed between the lower side of the peripheral wall of the groove and the hull of the ship. The spring means can be used to limit the movement of the circumferential wall of the groove and the downward movement. The cargo in the transport tank is supported directly on the ship's ship via the bottom of the trough, and the peripheral wall of the trough can be moved slightly relative to the hull of the ship in such a spring device Within the restriction. One of the disadvantages in the lit case is that The perimeter wall must be designed for a relatively thick walled 1373434. In addition, the other disadvantage is that it requires a relatively heavy trough. Therefore, the total weight of the trough is quite large. The possibility of increased specifications is limited, and the springs are limited. The device is fragile and requires maintenance. The deck access of the trough must be flexible. SUMMARY OF THE INVENTION It is an object of the present invention to provide a vessel having one or more liquid transport troughs disposed in the hull of the vessel, Wherein the above disadvantages are at least partially overcome; or, rather, an alternative form is provided. In particular, the present invention aims to provide a need for a liquid transport tank to be placed in the hull of the vessel. The material savings are substantial, while at the same time making the transport tanks strong and not too sensitive to the continued serious movement and deformation of the vessel. In particular, it is an object of the invention to make it possible to increase the size and to provide a simple structure that requires little or no maintenance. This object is achieved in accordance with the invention by a vessel having one or more liquid transport tanks disposed in the hull of the vessel in accordance with claim 1 of the scope of the patent application. Each of the transport bays includes a trough top and a trough supported on or associated with the lower deck of the ship's hull. The peripheral wall of the groove extending between the two portions is in particular a generally cylindrical design, but it may alternatively be of another shape such as an elliptical shape, a square shape, a multi-lobed shape having a plurality of splits, or a polygonal shape. The peripheral wall of the groove is connected to a first deformation absorber by its lower end portion, which is sequentially or directly connected to the lower deck of the ship's hull. In addition, the peripheral wall of the groove is connected to a second deformation absorber by its upper end, which is sequentially connected directly or indirectly to the upper deck of the ship's hull. The deformation absorbers are designed in a deformable manner such that deformation (eg, due to deformation of the hull of the vessel) can be absorbed by suitable deformation of the absorbers without causing the circumferential wall of the tank to be in the process Deformation, or not, may impose an improper load on the peripheral wall of the tank during the process. The lower deforming absorbent body extends circumferentially around the entire periphery of the peripheral wall of the groove and constitutes a portion of the groove wall, and forms a continuous seal between the peripheral wall of the groove and the bottom of the groove. According to the invention, one of the primary functions of the absorbent bodies is to reduce the axial stress in the peripheral wall of the groove. Reducing the axial stress in the peripheral wall of the groove will reduce the chance of crimping the peripheral wall of the groove. The axial stiffness of the absorbent bodies can be selected to advantageously prevent axial compression of the circumferential wall of the groove without the need to increase stiffness. The necessary wall thickness of the peripheral wall of the groove can thus advantageously be kept in a small state. The desired wall thickness can now be determined by the internal pressure of the stored liquid, the axial crush stress caused by the bending moment, the shear stress, and the productivity. The horizontal load will be substantially transmitted by shearing forces to the underside and upper side of the peripheral wall of the vessel via the deformation absorbers. This can be achieved by a considerable stiffness of the deformed absorbent body in the circumferential direction of the peripheral wall of the groove. When this is the case, the deformed absorbent body will then hold the peripheral wall of the groove in the circumferential direction. The deformation absorbers may even be made of a substantially rigid design in the circumferential direction described above and are then well suited for transmitting the horizontal load to the vessel and holding the circumferential wall of the tank in place. According to the invention, the peripheral wall of the groove retains its shape and will not be creased. The acceleration force acting on the liquid medium stored in the tank will cause a relatively small reaction force of 1373434 above and below the transport tank. The maximum torque caused by the action of this force now occurs in the tank. The circumference of the wall is roughly midway. This maximum torque is also quite small. The stresses are well distributed throughout the peripheral wall, and the maximum axial stresses generally occur at a position halfway down the peripheral wall of the groove, and the maximum shear stress occurs in connection with the deformed absorbers The location. The minimum wall thickness of the peripheral wall of the groove can thus be advantageously maintained in a small state. When this is the case, the groove wall can even be in the form of a film, especially if the wall is cylindrical. The stiffness of the deformed absorbent body in the axial direction and in the circumferential direction can be affected by changing the shape and wall thickness of the deformed absorbent body. Since the horizontal force on the transport trough is transmitted to both the lower side and the upper side of the vessel, a uniform load occurs on the vessel of the vessel. There is no need for any supporting structure along the middle of the hull of the vessel. The passage through the deck for loading and unloading does not need to be resiliently connected to the trough. The thin groove walls can be well insulated, which results in an energy savings and a high cargo quality after shipping. The life of the transport tank will be long and the transport tank will essentially require no maintenance. The risk of cracking of the groove wall due to collision will be reduced. The deformation absorber and the groove wall absorb some deformation due to the collision. Finally, the deformation absorbers are also suitable for absorbing the expansion or contraction of the wall of the tank which occurs depending on the temperature of the cargo. Since the peripheral wall of the groove is suspended by two springs (the deformation absorbers), when it is so, the groove wall will sink slightly under the influence of gravity. The extent of the sinking or movement is determined by the spring stiffness of the deforming absorbent body in the axial direction and the mass of the peripheral wall of the groove. Limiting the spring rate of the deformed absorbent body in the upward direction of -10- 1373434 will cause the peripheral wall of the groove to sink substantially after being placed between the deformed absorbent bodies, thereby compressing or stretching the deformed absorbent body. Some preferred embodiments of this sinking or moving are described in items 2-7 of the patent application. In a preferred embodiment, the deformation absorbers are designed in the circumferential direction of the peripheral wall of the slot; the peripheral wall of the slot has a stiffness greater than or equal to 1/3 of the stiffness of a reference wall; and the reference wall is All the way down is straight and made of the same material and has the same wall thickness curve as the groove wall of the groove equipped with the deformation absorbers. In a more preferred embodiment, the deformation absorbers are designed in the axial direction of the peripheral wall of the groove such that the elastic stiffness in the axial direction of the reference wall is relative to the peripheral wall of the groove along with the deformation absorber. Greater than 2; and the reference wall is straight down all the way and made of the same material and has the same wall thickness curve as the circumferential wall of the groove along with the deformed absorber. Preferably, the two spring stiffness conditions are met. In this manner, the peripheral wall of the trough is suspended between two deforming absorbent bodies on the vessel of the vessel. The roof may form an integral part of the upper deck of the hull of the vessel. However, if the bottom of the trough and/or the top of the trough are designed separately, they may follow the deformation of the hull of the vessel without undue resistance, and the wall thickness of the trough and the top of the trough may advantageously be Keep it in a small state. Together, the above owners can achieve significant savings in materials. In particular, the upper deformation absorber also extends substantially over the entire circumference of the peripheral wall of the groove. This continuous connection ensures that the local stress concentration can be avoided by -11- 1373434. More particularly, the upper deformation absorber also forms part of the groove wall and is received between the peripheral wall of the groove and the top of the groove. The transition position between. The deforming absorbent body forms a continuous sealed connection between the peripheral wall of the groove and the top of the groove. The separate deformable support member can be configured to support the peripheral wall of the groove in the axial direction and/or to partially absorb the liquid pressure. The deformed absorbers can then be designed to move substantially freely in the axial direction, in other words, without undue resistance. However, it is also possible to make the deformed absorbent bodies rigid in the axial direction of the groove, so that the two deformed absorbent bodies collectively or partially support the peripheral wall of the groove. In the latter case, when it is so, the peripheral wall of the groove is finally suspended between the deformation absorbers without having to provide any additional support. The deformed absorbent bodies are advantageously rigid at least in the circumferential direction of the transport tank. This can be achieved by a suitable ratio between the shape, wall thickness, strength and stiffness in the different directions of the deforming absorbers. Since the deformation absorbers are rigid in the circumferential direction, in other words, the deformation absorbers can maintain their shape in the circumferential direction under load, the deformation absorbers can fix the groove peripheral wall in an appropriate position. on. Further preferred embodiments of the vessel are described in the dependent claims. The invention further relates to a transport tank for a vessel constructed in accordance with the invention, to a method for locating the transport tank in the vessel, and to a use of the vessel. -12- 1373434 The deformation absorbers are arranged symmetrically with respect to the groove peripheral wall 25 such that no resultant hydraulic force occurs in the downward direction at the deformation absorber. Several individual supports will be omitted here. Several other variations of the embodiments of the deformation absorbers are shown in Fig. 3. In each of these variations, the designer can construct a mutual coordination between wall thickness and material selection (strength and modulus of elasticity) as desired. The five variations at the bottom are provided with means for absorbing the pressure from the cargo, and the pressure is applied to the deforming absorber. These devices are constructed by a compressible support disposed on the outer side of the deforming absorbent body. The examples shown herein are pre-formed rubber support blocks, springs, insulation materials with limited compressibility, liquid bags, and the like. The deformed absorbent body can thus be made thinner so that it can absorb more deformation. Fig. 3 also shows a variant in which the deformation absorbing system consists of the peripheral wall of the groove and the wall of the groove or the top of the groove which are substantially connected to each other at right angles. If necessary, a small rounded corner can be placed at the position of the connection", in particular by designing the wall of the deformed absorbent body close to its connection with the bottom of the groove or the top of the groove, so that The wall portion is formed, for example, at a thin wall at this point to be slightly moved upward and downward, thereby absorbing the deformation of the hull of the vessel. The spring means can also be placed close to the joint' and the spring means can in particular be in a pre-tensioned state and in particular can operate along the axial direction of the groove. In Figs. 4 to 6, a groove peripheral wall 40 is directly suspended by the two deformation absorbers 41, 42 on the upper deck 43 and the lower deck -15-1373434 44 of the hull 45 of the vessel. Here, the bottom of the trough and the top of the trough form an integral part of the lower deck 44 and the upper deck 43, respectively. The deformation absorbers 41, 42 are both in the shape of a bellows, and extend in the circumferential direction along the entire circumferential wall 40, and are both between the groove peripheral wall 40 and the groove bottom and the groove top. A continuous sealed connection is formed. The groove peripheral wall 40 is here a cylindrical design. It is clearly shown in Fig. 5 that if there is a deformation of the hull 45 of the vessel, in this case a combination of twisting and bending of the lower deck, the walls and the upper deck of the vessel, the deformation will It is completely absorbed by the deformation absorbers 41 and 42. The deformed absorbent bodies are locally compressed or stretched in the axial direction (i.e., parallel to the centerline 47 of the peripheral wall 40 of the groove). The groove peripheral wall 40 is thus subjected to little or no additional load and can thus substantially retain its original shape. Figure 7 shows a plurality of transport slots 70 implemented in accordance with the present invention which are disposed in a hull 71 of a vessel. The slots 70 are of different sizes and thus utilize all of the free space in the hull 71 of the vessel. Moreover, the slots 70 are configured such that their peripheral walls are not in contact with each other and with the hull of the vessel. As will be apparent, the deformed absorbent body 72 will extend around the entire groove and form an integral part of the groove wall. In the following figures, the same and similar components are denoted by the same reference numerals. Fig. 8 shows a variation of Fig. 6, in which the groove bottom 80 and the groove top 81 are designed as separate parts. Both are fully supported on the lower and upper decks 44 and 43, respectively. The deformed absorbent bodies 42, 41 are permanently attached to the trough bottom 80 and the trough top 81, respectively, and/or to the lower and -16-1373434 upper decks 44 and 43. Figure 9 shows a variation of Figure 8, wherein the groove bottom 80 is supported on the lower deck 44 by a slightly compressible layer 90 (e.g., a cork layer or a plywood layer). The lower deformation absorbent body 42 is coupled to both the bottom of the groove and the lower deck 44. The trough top 81 is supported on the upper deck 43 by a plurality of sections 91. The upper deformation absorber 41 is here connected to both the trough top 81 and the upper deck 43. Figure 10 shows a variation of Figure 9, wherein the groove bottom 80 is supported on the lower deck 44 by a plurality of sections 1 , and the groove 81 is replaced by a slightly compressible layer 101. Connected to the upper deck 43. Figure 11 shows a variation in which the groove bottom 80 and the groove 81 are supported on a compressible layer 110. The deformation absorbers 111 are composed of double semi-circular deformation sections. Fig. 12 shows a variation in which a groove peripheral wall 120 is suspended between the upper and lower semi-circular deformation sections 121. Further, a plurality of other variable absorption bodies 122 are integrally formed with the groove peripheral wall 120. The deformation absorptions here have the same shape as the deformation sections 121. Figure 13 shows a variation in which the lower and upper deformation absorptions 130 include a plurality of semi-circular sections 131 that are respectively plunged into a plurality of straight sections 132 along the lower and upper decks. Figure 14 shows a variation in which the entire peripheral wall 140 is comprised of a plurality of interconnected bellows sections. The upper and lower sections constitute the deformation absorbers 141, 142 herein, and the groove peripheral wall 140 is suspended therebetween. FIG. 15 shows a variation of FIG. 10, wherein a downward tilt is supported by the support 80. This is supported on the plate 44 by a plurality of sections 151 from the body to the groove bottom 150 at the center of the slanting -17-1373434. The groove bottom 150 here has an inclination angle of 5 degrees with respect to the lower arm. This has the advantage that the groove will be easier to clear. Figure 16 shows a variation of Figure 9, in which a 160 is supported on the peripheral wall 40 of the groove. The groove peripheral wall 40 and the absorber 161 which is suspended by the deformation absorber 161 on the upper deck 431 are therefore not formed so as to constrain the liquid to a part of the groove wall. Furthermore, one or more independent supports are provided whereby the upward movement of the peripheral wall 40 of the groove can be restricted. This upward shift can occur due to the pressure of the liquid acting on the top 160 of the tank. Fig. 17 is a view showing a modification of Fig. 16, wherein the dome-shaped top 170 deformation-absorbing body 171 which is directly supported on the peripheral wall 40 of the groove is constituted by a quarter-circle section. This 162 is omitted here. However, the lower end of the peripheral wall of the groove is connected to the struts 172. The support members 172 preferably include a stretch and an eyebrow to prevent compression of the deforming absorbent body 171 due to the action thereon, and so that the peripheral wall 40 of the groove can be caused by the liquid pressure on the action 170. Move up to a minimum. Figure 18 shows a variation in which the trough 81 is suspended from the upper deck 43 by a segment 180. The peripheral wall 40 is interposed between the lower deformation absorber 171 and an upper deformation absorber ι81. The absorbent body 181 is partially integral with the groove wall and partially protrudes from the upper deformation absorbent body between the groove plates 43. The quadrilateral deformation section 183 and a horizontal portion 184 are included. In this sub-flat 44, for example, and clean up. Rigid trough top Slot top 160:. The deformation of the member 162 in the groove, for example, the top of the groove is composed of f. The support member is slid into the spring, the liquid pressure is suspended by the plurality of regions at the top of the slot, and the upper body portion is respectively slid in the horizontal direction of the slot wall -18 - 1373434. Down and on the deck. In the numerical example below with reference to Figure 21, we use a cylindrical stainless steel tank with the following data: h = 7000 mm r = 5000 mm tw = 5 mm Pstainless steel = 7950 kg/mm 200000 N/mm2 9.81 m / s2 = 240 N/mm2 and has the following dimensions: h〇p = 1000 mm b〇p = 100 mm t〇n = 4 mm groove height groove radius E g σ, wall thickness of the groove wall stainless steel density stainless steel Elastic coefficient Gravity acceleration Allowable tensile force of stainless steel The two deformation absorbers have the same shape ht, 500 mm. The height of the deformable absorber is deformed. The width of the absorber is the wall thickness of the absorber. The height of the groove wall is a single deformation absorber. The following features have been determined by the FEM calculation: Deformation: Axial stiffness: DPtn C p 12.1mm N/mm 1.22 Ignore the stiffness of the groove wall itself. The theoretical sinking of the groove wall at the midway position: Sinking amount

Cp =—the stiffness of the deformed absorber (N/mm/mm) G tw = tw " · Pstainless steel " 8 ~ 0.005 · 5 " =1 950 N/m = 1.95 N/mm sinking amount = Glw / (2·Cp) = 1.95/(2. 1.22) = 0 According to the formula of the second paragraph of the patent application, the groove wall is the most C. h · / r = 1 · e 7 · 7000 \j5000 = 0.05 mm Therefore, the sink wall sinks far more than 15 times the minimum 根据 according to the scope of the patent application. Because of the stiffness of the deformation absorbers in the axial direction, the deformation absorbers absorb the same deformation when the upper deck is absorbed relative to the lower deck. Ignore the amount of deformation of the perimeter wall, which is all:

Dtot = 2 · Dpmax = 2 · 12.1 = 24.2 mm According to the scope of the patent application, item 5, the groove wall together with the body should then be able to be attached to the lower deck with a right Y*h/1000=l*7000 /1000 = 7mm movement. The circumferential wall-shaped absorbent body can thus absorb at least 3.4 times more than the minimum enthalpy according to the scope of the patent application. The circumferential wall of the groove, together with the axial stiffness of the deformation absorbers, is compared to a reference wall. The reference wall: - is straight down one way: one is the same material as the circumferential wall of the groove and the deformation absorber - having the same wall as the groove wall and the deformation absorbers 7950 - 9.81 .80 mm The amount of small sinking should be the same as listed in 2 items, so the deformation amount of the wall when moving is made at least in conjunction with the above-mentioned item 5; thick curve. -21 - 1373434 In general, the axial stiffness of the reference wall can be determined as follows: c w = Ν /δ w where:

Cw = the axial stiffness of the reference wall, expressed in Newtons per millimeter of compression per millimeter of circumference [N/mm2]. N = edge load, expressed in Newtons per millimeter of circumference [N/mm]. 5w = the amount of compression of the reference wall at a particular edge load, expressed in millimeters [m m]. If the circumferential wall of the groove and the deformed sections are made of the same material and all have an equal and uniform wall thickness, the stiffness of the reference wall is equal to: cw = (E · tw) / hw where:

Cw = stiffness of the reference wall in the axial direction [N/mm2]. E = elastic coefficient, expressed as [N / m m2]. U = thickness of the (homogeneous) reference wall, expressed as [mm]. " = the height of the reference wall expressed in [mm] is equal to the height of the groove. If the circumferential wall of the groove and the deformed sections have different wall thicknesses made of different materials, the following reference wall The formula for axial stiffness will apply:

Cw =____|_ hi h2 hn έγιγ + + ......+ In this case, the reference wall is divided into two cylindrical walls, each having its own wall thickness, its respective height, and its respective elasticity coefficient. This -22 - 1373434 means that we can determine the stiffness of the reference wall according to the numerical example as follows: c 1 = 133 N/mm/mm 1000 5000 1000 200000 · 4 + 200000 · 5 200000 · 4 equipped with such deformation absorption The stiffness of the groove wall of the body is Cwp. This stiffness is defined as follows:

Cwp = N/6wp This stiffness can be calculated as follows: 1 1

Cw = - = - =0.61 N/mm/mm 丄丄丄 1 5000 1

Cp + Ctw + c7 1.22 + 200000 · 5 + 1.22 This produces the ratio of the axial spring stiffness of the reference wall to the axial spring stiffness of the circumferential wall of the groove equipped with several deformation absorbers:

Cw/CWp = 133/0.61 = 219 According to item 8 of the patent application, the minimum enthalpy of this comparison is greater than or equal to 2, so that the stiffness ratio in this example is more than 1 〇〇.

According to claim 16 of the patent application, at least one of the deformation absorbers has a stiffness of less than or equal to 20 N/mm/mm. The stiffness of the two deformation absorbers is here 1.22 N/mm/mm, and therefore less than 20. According to the 19th item of the patent application, the wall thickness of the groove wall should be less than X. The following formula can be used to find X: Γ

J ^./-7000-10000 = 23.6mm -23 - 1373434 X = max [ 23.6 and 10) = 23.6 mm The wall thickness of the groove wall is 5 mm, which is therefore less than 23.6 mm. Depending on the material selected as the deformed absorbent body, depending on whether the deformed absorbent body constitutes an integral part of the groove wall, and depending on the cargo to be transported, the absorbent body may be additionally coated with an anti-chemical Coating or lining, such as a stainless steel layer. Many variations are possible without departing from the scope of the illustrated embodiments. For example, the various aspects shown in the drawings can be further combined with each other. The bottom of the trough or the top of the trough may be of a non-flat shape, such as a dome or a cone. Other embodiments of the deformation absorbers are also conceivable as long as they continue to meet the necessary conditions for the axial and circumferential deformability, respectively, and in this way advantageously load from the slot Removed from the wall. The support members can also be in a controllable form, for example, in the form of a plurality of hydraulic piston-cylinder systems distributed around the periphery of the periphery. In particular, the measuring sensors can be arranged here to control the supports in view of the current measured number. A transport tank constructed in accordance with the present invention is intended to transport liquids, especially liquids that must be transported under ambient pressure. The transport tank is specifically designed to store the liquid medium therein at a maximum overpressure of approximately 1 bar above the liquid level. The deformed absorbent bodies can be constructed of a plurality of layers so that the plurality of layers are not joined to each other and thus can be moved relative to each other. This imparts great flexibility to the deformed absorbent bodies. In this way, the invention provides a transport trough in the hull of a vessel and a very advantageous design of the support member of the -24 - 1373434, which results in a very large savings in material, since a trough is suspended Placed between an upper deck and a lower deck and combined with the use of such absorbent bodies at the bottom and upper sides of the peripheral wall of the tank. Therefore, the manufacturing and transportation costs will be correspondingly low, and a high level of safety and reliability can be ensured even in the event of a collision. These transport bays may advantageously be constructed in a factory environment and then connected to the vessel's hull in an isolated state or otherwise. If there is an isolation device, it can be placed on the outside of the slots. These slots are easy to clean and can be cleaned up even in an automated manner.
