Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a sail base assembly and an Aframax tanker. Background Technology

[0002] In shipbuilding, the design principles of sail foundations share certain similarities with those of large equipment foundations (such as drilling rig foundations, crane foundations, and cantilever beam foundations). However, due to the large number and wide distribution of sail foundations, and their significant space occupation when the sails are in their stowed or collapsed states, their structural design must be adjusted according to actual layout requirements and operational conditions. Initial design schemes often fail to fully meet actual engineering requirements. In particular, during the arrangement of sail equipment, spatial interference issues arise between the sail foundations and deck cables due to limitations imposed by the mooring equipment layout on the main deck, necessitating further coordination and optimization. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to solve the problem of interference between the sail base and the deck cables caused by the arrangement restrictions of the main deck mooring equipment in the prior art, and to provide a sail base assembly and an Aframax tanker.

[0004] A sail base assembly includes a base body disposed on a deck, the base body having a mounting portion for assembling external equipment components, and a cutout portion provided at one end of the base body near the deck, the cutout portion extending to both sides of the base body, the cutout portion being used for threading ropes.

[0005] In this design, a perforated section is provided at one end of the base body near the deck, allowing cables to pass through the bottom of the base body. This ensures that the cables can pass through the sail bases without interference without moving the sail bases and mooring equipment, improving space utilization efficiency. This also ensures that the ship's critical mooring operation functions and the arrangement of the sail propulsion system are no longer mutually exclusive, maximizing the overall performance and operational safety of the ship. It avoids the huge costs incurred due to large-scale design changes, thus significantly saving on the economic costs of ship operations and making space utilization highly adaptable and flexible.

[0006] Preferably, the lower side of the hollow portion is defined by the deck, the cross-sectional shape of the hollow portion is arched, and the arch angle of the arch does not exceed 90°.

[0007] In this design, by defining the lower side of the perforated section by the deck, the perforated section is in direct contact with the deck. The cables laid in the perforated section will not rub against the lower side of the perforated section, thus avoiding hindering cable operation, reducing work efficiency, and minimizing the possibility of cable wear. At the same time, by setting the perforated section in an arch shape, it can be ensured that the edges of the perforated section have good mechanical properties to withstand the pressure of the base body loaded on the edges of the perforated section, ensuring structural stability. The smooth curved edges of the arch can also greatly reduce the frictional resistance of the cables. Furthermore, by controlling the arch center angle to not exceed 90°, the stress performance of the perforated section can be improved.

[0008] Preferably, the base body further includes two or more support legs, and the hollow portion is disposed between two of the support legs.

[0009] In this design, by placing the hollowed-out portion between the support feet, it can be ensured that the center of gravity of the sail base assembly does not deviate from the coverage area of ​​the support structure, thereby improving the stability of the sail base assembly.

[0010] Preferably, the hollowed-out portion is a through hole.

[0011] Preferably, the through hole is inclined along the extension direction of the deck, and the inclination angle of the through hole corresponds to the inclination angle of the deck.

[0012] In this solution, by setting the inclination angle of the through holes to correspond with the inclination angle of the deck, the extension angle of the cable passing through the through holes is consistent with the extension angle laid on the deck. This can improve the efficiency of the cable moving in the through holes and reduce the difficulty of operation.

[0013] Preferably, the inclination angle of the through hole is 3.6°.

[0014] Preferably, the through hole further includes a sleeve, which is disposed on the support structure of the base body.

[0015] In this solution, by installing a sleeve in the through hole of the support structure of the base body, the structural strength of the through hole wall can be strengthened and the load-bearing performance of the through hole wall can be improved.

[0016] Preferably, the number of through holes is two or more, and the diameter of the through holes is greater than 600 mm.

[0017] Preferably, the mounting portion is located on the upper part of the base body, and the position of the hollowed-out portion is lower than the position of the mounting portion.

[0018] Preferably, the hollowed-out portion is further provided with a flange structure, which surrounds the hollowed-out portion and is used to strengthen the structural strength of the hollowed-out portion and reduce the friction between the rope and the hollowed-out portion.

[0019] An Aframax tanker, the Aframax tanker including the sail base assembly as described above.

[0020] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0021] The positive and progressive effects of this invention are as follows:

[0022] This invention features a perforated section at one end of the base body near the deck, allowing cables to pass through the bottom of the base body. This ensures that cables can pass through the sail bases without interference without moving the sail bases or mooring equipment, improving space utilization efficiency. It also ensures that the ship's critical mooring operation functions and the arrangement of the sail propulsion system are no longer mutually exclusive, maximizing the overall performance and operational safety of the ship. This avoids the huge costs incurred due to large-scale design changes, thus significantly saving on the economic costs of ship operations and providing excellent adaptability and flexibility in space utilization.

[0037] The present invention is further illustrated below by way of embodiments, but the invention is not limited to the scope of the embodiments described herein. Experimental methods in the following embodiments that do not specify specific conditions were performed according to conventional methods and conditions, or as selected according to the product instructions.

[0038] Example 1

[0039] like Figures 1-2 As shown, this embodiment provides a sail base assembly 001, which includes a base body 1 disposed on a deck. The base body 1 has a mounting part 11, which is used for assembling external equipment components. In this embodiment, the mounting part 11 includes a plurality of through holes 121. The mounting part 11 is disposed at the upper end of the base body 1 and is used to install the shaft part of the connecting equipment. The base body 1 has a hollow part 12 at one end near the deck. The hollow part 12 extends to both sides of the base body 1 and is used to thread ropes. In this embodiment, the lower side of the hollow part 12 is defined by the deck. The cross-sectional shape of the hollow part 12 is arched, and the arch center angle angle does not exceed 90°. The two ends of the arch are respectively connected to arch arms with straight extension paths. Specifically, in this embodiment, the arch center angle angle is 83°. The two arch arms of the arch are of unequal length, with lengths of 915mm and 1211mm respectively. The arch is not a symmetrical structure. By having the lower side of the perforated section 12 defined by the deck, the perforated section 12 is in direct contact with the deck. The cable laid in the perforated section 12 will not rub against the lower side of the perforated section 12, thus hindering cable operation, reducing work efficiency, and reducing the possibility of cable wear. At the same time, by setting the perforated section 12 in an arch shape, it can be ensured that the edge of the perforated section 12 has good mechanical properties to withstand the pressure of the base body loaded on the edge of the perforated section 12, ensuring structural stability. The smooth curved edge of the arch can also greatly reduce the frictional resistance of the cable. Furthermore, by controlling the arch center angle to not exceed 90°, the stress performance of the perforated section 12 can be improved. In this embodiment, by having the lower side of the hollow section 12 defined by the deck, the hollow section 12 is in direct contact with the deck. The cable laid in the hollow section 12 will not rub against the lower side of the hollow section 12, thereby hindering cable operation, reducing work efficiency, and reducing the possibility of cable wear. At the same time, by setting the hollow section 12 in an arch shape, it can be ensured that the edge of the hollow section 12 has good mechanical properties to withstand the pressure of the base body loaded on the edge of the hollow section 12, ensuring structural stability. The smooth curved edge of the arch can also greatly reduce the frictional resistance of the cable. Furthermore, by controlling the arch center angle to not exceed 90°, the stress performance of the hollow section 12 can be improved.

[0040] In addition, in this embodiment, the base body 1 also includes two or more support legs 13, and only one hollow part 12 is provided. The hollow part 12 is provided between two of the support legs 13. The hollow part 12 is also provided with a flange structure 122. The flange structure 122 is provided around the hollow part 12. The flange structure 122 is used to strengthen the structural strength of the hollow part 12 and reduce the friction between the rope and the hollow part 12. The edge where the support leg 13 connects with the hollow part 12 is defined by the hollow part 12. The edge where the support leg 13 connects with the hollow part 12 is provided with the flange structure 122.

[0041] This embodiment also provides an Aframax tanker, which includes the sail base assembly 001 as described above.

[0042] In other embodiments, there may be two or more support feet 13, and the hollowed-out portion 12 is arranged between two adjacent support feet 13. The hollowed-out portion 12 may be provided with a sleeve 1211, which can connect the ends of the hollowed-out portion 12 located on both sides of the base body 1 to form an arched channel, which will not be described in detail here.

[0043] Example 2

[0044] like Figures 3-4 As shown, its structure is roughly the same as that of the sail base assembly 001 in Embodiment 1. The difference is that the hollow part 12 is a through hole 121. The through hole 121 is inclined along the extension direction of the deck. The inclination angle of the through hole 121 corresponds to the inclination angle of the deck. In this embodiment, the inclination angle of the through hole 121 is 3.6°. By setting the inclination angle of the through hole 121 to correspond to the inclination angle of the deck, the extension angle of the cable passing through the through hole 121 is consistent with the extension angle laid on the deck. This can improve the efficiency of the cable moving in the through hole 121 and reduce the difficulty of operation. In addition, the through hole 121 in this embodiment also includes a sleeve 1211. The sleeve 1211 is disposed on the through hole 121 located on the support structure of the base body 1. Since opening a hole in the support structure of the base body 1 will weaken the load-bearing performance of the support structure and easily cause stress concentration on the hole wall and structural damage, this embodiment strengthens the structural strength of the hole wall and improves the load-bearing performance of the hole wall by providing a sleeve 1211 on the through hole 121 of the support structure of the base body 1.

[0045] In addition, in this embodiment, there are three through holes 121, and the axial height of the three through holes 121 is different. The through holes 121 are adapted to the working requirements of the cable to be threaded. The diameter of the through holes 121 is greater than 600mm, which can accommodate the size of commonly used cables and meet the basic operation requirements. The ends of the through holes 121 on both sides of the base body 1 are provided with flanged structures 122. The hollow part 12 is also provided with flanged structures 122. The flanged structures 122 are arranged around the hollow part 12. The flanged structures 122 are used to strengthen the structural strength of the hollow part 12 and reduce the friction between the rope and the hollow part 12.

[0046] In other embodiments, the tilt angle of the through hole 121 can be adapted to the angle of the deck or other structures. In addition, a sleeve 1211 can be provided for the through hole 121, not limited to a special position. Other structures such as chamfered structures can also be used to reduce the friction between the rope and the edge of the through hole 121, which will not be elaborated here.

[0047] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
