Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a design method and a ship for mixed loading of containers and vehicles. Background Technology

[0002] In related technologies, the vehicle compartment of a roll-on / roll-off (Ro-Ro) ship is limited to loading vehicles. Trucks and trailers can be loaded and unloaded, or used as carriers for container transport. That is, trucks and trailers (including their cargo) can be driven directly onto and off the ship without separate loading and unloading of cargo. The core advantage of this mode is high efficiency and low cargo damage. However, if a Ro-Ro ship only transports vehicles, insufficient cargo capacity may lead to empty compartments and low utilization of ship space. Summary of the Invention

[0003] The purpose of this invention is to provide a design method and a vessel for mixed container and vehicle loading, which improves the space utilization of the vessel and reduces the design difficulty.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A design method for a ship capable of mixed loading of containers and vehicles includes:

[0006] Assess the capacity of the vehicle compartment, designate a loading area, and construct side passageways around the loading area;

[0007] The loading area is provided with multiple lashing components along the width direction of the ship, with a first preset distance between them; the lashing components include multiple lashing pieces arranged along the length direction of the ship, with a second preset distance between them, and the lashing pieces are used to secure the vehicle;

[0008] The loading area is divided into a first area and a second area, and locking devices are respectively installed in the first area and the second area. The locking devices are used to fix the container. The container is loaded in the first area at a first angle and in the second area at a second angle. The loading area is capable of loading vehicles and / or containers.

[0009] In some embodiments, the loading area is provided with lane lines along the length of the vessel, and the lashing device is located on the lane lines.

[0010] In some embodiments, the loading area further includes a third area, in which the locking device is disposed, and the container is loaded in the third area at a third angle.

[0011] In some embodiments, the locking device includes four locking fasteners located at the four corners of a first rectangle for securing the first container.

[0012] In some embodiments, four first L-shaped markers are provided at the four corners of the first rectangle.

[0013] In some embodiments, two sets of locking devices are arranged along the first side length direction of the first rectangle, and four locking fasteners located at both ends of the first side length direction of the two first rectangles form a second rectangle, and four locking fasteners located at the corners of the second rectangle are used to fix the second container.

[0014] In some embodiments, four second L-shaped markers are provided at the four corners of the second rectangle.

[0015] In some embodiments, a maintenance access channel is provided on the side of a portion of the locking device.

[0016] In some embodiments, both the lashing element and the locking device are embedded in the deck.

[0017] A vessel includes a loading area and a side passageway, the loading area being equipped with lashing and locking devices, and designed using the design method for a vessel with mixed container and vehicle loading as described in any of the preceding claims.

[0018] The beneficial effects of this invention are:

[0019] This invention provides a design method and vessel for mixed container and vehicle loading. By implementing two layouts within the same loading area—one for lashing devices and the other for locking devices—the lashing devices secure vehicles, while the locking devices secure containers. This allows the same area to be used for both vehicle and container securing, achieving a mixed-mode loading of vehicles and containers. This enables efficient use of space according to demand, improving vessel space utilization and ultimately increasing the vessel's loading efficiency. For customers requiring simultaneous transport of containers and vehicles, this mixed-mode meets their needs, eliminating the need for separate vessels, reducing logistics costs, and broadening the service offerings for shipping companies.

[0020] By reusing the positions of lashing and locking devices in the loading area and designing and installing them in stages, the contradiction of overlapping spaces is resolved, reducing design complexity. Since containers occupy a large area and the loading area may have irregular shapes, dividing the container into first and second zones allows it to be fixed at appropriate angles according to the shapes of the first and second zones, further maximizing space utilization.

[0037] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] like Figures 1-10 As shown, this embodiment provides a design method for a ship that mixes containers and vehicles, including the following steps:

[0041] S100. Assess the capacity of the vehicle compartment, set up a loading area 100, and set up side passages 200 around the loading area 100.

[0042] S200, the loading area 100 is provided with multiple lashing components along the width direction of the ship, with a first preset distance between them; the lashing components include multiple lashing pieces 300 provided along the length direction of the ship, with a second preset distance between them, and the lashing pieces 300 are used to secure the vehicle.

[0043] S300, The loading area 100 is divided into a first area 110 and a second area 120. Locking devices are provided in the first area 110 and the second area 120 respectively. The locking devices are used to fix the container. The container is loaded in the first area 110 at a first angle and in the second area 120 at a second angle. The loading area 100 is capable of loading vehicles and / or containers.

[0044] By implementing two layouts within the same loading area 100—one for lashing devices 300 and the other for locking devices—the lashing devices 300 are used to secure vehicles, while the locking devices are used to secure containers. This allows the same area to be used for both vehicle and container securing, enabling a mixed-mode operation. This allows for the rational use of space according to demand, improving ship space utilization and ultimately increasing ship loading efficiency. For customers who need to transport both containers and vehicles simultaneously, this mixed-mode operation meets their needs, eliminating the need for separate transport on two vessels, reducing customer logistics costs, and broadening the service offerings for shipping companies.

[0045] Furthermore, the binding element 300 and the locking device can be installed in stages.

[0046] Because the lashing components 300 and locking devices are reused within the same loading area 100, the contradiction of spatial overlap is resolved and the design difficulty is reduced by designing and installing them in stages. The layout of the lashing components 300 is adjusted according to the vehicle information, and the layout of the locking devices is adjusted according to the container information, preventing a complete redesign of the layout due to changes in either the container or the vehicle, thus achieving risk isolation.

[0047] Since containers occupy a large area and the shape of loading area 100 may be irregular, by dividing the container into a first area 110 and a second area 120, the container can be fixed at the corresponding angle according to the shape of the first area 110 and the second area 120. That is, the container is loaded and fixed at a first angle in the first area 110 and at a second angle in the second area 120, which can further make full use of the space.

[0048] Since the side passage 200 is a necessary structure, the side passage 200 and the loading area 100 are first divided to define the boundary, namely the side passage 200. Then, the loading area 100 is designed in detail, namely the lashing parts 300 and the locking device. This avoids area conflicts in advance, clarifies design priorities, and ensures that the overall design meets the requirements.

[0049] Optionally, the first preset distance is approximately 2900mm, and the second preset spacing is approximately 2400mm.

[0050] Furthermore, in step S300, the loading area 100 is further provided with a third area 130, in which a locking device is installed, and the container is loaded in the third area 130 at a third angle. The loading area 100 is further divided according to its shape to fully utilize the ship's space.

[0051] like Figure 2 and Figure 3 As shown, two first zones 110 and one second zone 120 are arranged along the width of the ship, with the two first zones 110 located on either side of the second zone 120. A third zone 130 is located on the side of the second zone 120 and the first zone 110 along the length of the ship, closer to the gangway. The containers are arranged in a rectangular configuration. In the first zone 110, the long sides of the rectangular containers are arranged along the length of the ship; in the second zone 120, the short sides of the rectangular containers are arranged along the length of the ship; and in the third zone 130, the long sides of the rectangular containers are arranged at an acute angle to the length of the ship. This arrangement allows for the placement of the maximum number of containers.

[0052] Some locking devices have access passages 170 on their sides. For example, the second area 120 is further divided into multiple installation zones, each for securing one or more containers. Access passages 170 are provided between the installation zones to facilitate heat dissipation. Optionally, the installation zones are used for securing refrigerated containers, i.e., access passages 170 are reserved around the refrigerated containers and sockets are provided on the side of the hull. Optionally, the width of the access passages 170 is 600mm.

[0053] Loading area 100 is provided with lane lines 140 along the length of the vessel, and lashing pieces 300 are located on lane lines 140. Optionally, lane lines 140 are 50mm wide yellow painted lines that connect multiple lashing pieces 300 on the lashing assembly in series for easy identification and to facilitate loading and securing of vehicles.

[0054] Optionally, a lane closure line 180 is provided along the width of the vessel near the entrance of the gangway. The lane closure line 180 is a 50mm wide yellow painted line.

[0055] like Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, for example, there are two types of containers, namely a first container and a second container. The first container and the second container have the same width. The length of the first container is 20 feet, and the length of the second container is 40 feet.

[0056] The locking device includes four locking fasteners 400 located at the four corners of a first rectangle 400A for securing the first container. Two sets of locking devices are arranged along the first side length 400B (long side) of the first rectangle 400A. The four locking fasteners 400 located at both ends of the first side length 400B of the two first rectangles 400A form a second rectangle 400C, where the long side of the second rectangle 400C is twice the long side of the first rectangle 400A, and the short side of the second rectangle 400C is equal to the short side of the first rectangle 400A. The locking fasteners 400 located at the four corners of the second rectangle 400C are used to secure the second container, thus enabling applicability to containers of different sizes, i.e., the first and second containers. In other embodiments, adaptive settings are made according to the shape and size ratios of different containers to allow for the loading and securing of multiple containers in the same area.

[0057] Four first L-shaped markings 150 are located at the four corners of the first rectangle 400A, and four second L-shaped markings 160 are located at the four corners of the second rectangle 400C. The use of first L-shaped markings 150 and second L-shaped markings 160 facilitates identification and allows for the loading of containers of different sizes and models. Specifically, the first L-shaped markings 150 and second L-shaped markings 160 are both 50mm wide white painted lines. Optionally, the first L-shaped markings 150 and second L-shaped markings 160, which do not distinguish between areas, can be omitted, allowing for identification based on adjacent markings, thus avoiding excessive density.

[0058] The first L-shaped sign 150 includes a first long side 151 and a first short side 152, which form an L-shape. The first L-shaped signs 150 at the four corners of the first rectangle 400A are located within the border of the first rectangle 400A. The first long side 151 extends along the long side of the first rectangle 400A, and the first short side 152 extends along the short side of the first rectangle 400A. The second L-shaped sign 160 includes a second long side 161 and a second short side 162, which form an L-shape. The second L-shaped signs 160 at the four corners of the second rectangle 400C are located within the border of the second rectangle 400C. The second long side 161 extends along the long side of the second rectangle 400C, and the second short side 162 extends along the short side of the second rectangle 400C. The length of the second long side 161 is greater than the length of the first long side 151, and the length of the second short side 162 is greater than the length of the first short side 152, thereby facilitating the differentiation and identification of the first rectangle 400A and the second rectangle 400C for loading and fixing the first container or the second container.

[0059] By setting up lane lines 140, first L-shaped markings 150, and second L-shaped markings 160, the loading of vehicles and stacking of containers by crew members can be clearly seen, enabling efficient completion of terminal operations and stacking management.

[0060] like Figure 4 As shown, when lane line 140 overlaps with the first L-shaped sign 150 and the second L-shaped sign 160, the overlapping part of lane line 140 is discontinuous. The first L-shaped sign 150 and the second L-shaped sign 160 are located at the discontinuities of lane line 140, and the interval between the first L-shaped sign 150 and the second L-shaped sign 160 and lane line 140 is approximately the same, which is aesthetically pleasing.

[0061] The vehicle compartment's height allows for the stacking of two standard containers, and the deck's 500mm allowable load meets the container stacking requirements. This allows for the simultaneous loading of containers and vehicles while meeting the ship's 500mm deck load requirement, ensuring safety and reliability. The calculation of the 500mm deck allowable load and the finite element analysis of the vehicle compartment can be performed using existing technologies.

[0062] Generally, the structural strength design of a ship is directly related to the type of vehicle it carries. The structural design is based on the vehicle type with the largest tonnage provided by the shipowner, and prefabricated matching lashing components 300 are selected to ensure safety and reliability.

[0063] Optionally, the upper container can be secured with an automatic twist lock for easy operation. The specific automatic twist lock is existing technology and will not be described in detail here.

[0064] like Figures 6-8 As shown, both the lashing element 300 and the locking device are embedded in the deck 500. The locking device is embedded in the deck 500 to prevent it from protruding from the deck 500 and affecting the securing of the loaded vehicle. The lashing element 300 is embedded in the deck 500 to prevent it from protruding from the deck 500 and affecting the securing of the loaded container.

[0065] In one embodiment, mounting holes are machined on the deck 500 by CNC cutting, and the lashing member 300 and the locking device are respectively installed into the corresponding mounting holes. Reinforcing ribs are set near the mounting holes to ensure that the structural strength meets the requirements.

[0066] Optionally, the binding element 300 and the locking element 400 can be based on existing technologies and will not be described in detail here.

[0067] Furthermore, such as Figure 5 As shown, the two locking fasteners 400 in the upper left corner are located in two installation areas for loading and securing containers, and a detection channel is provided between the two installation areas. Since the two locking fasteners 400 are separately installed, two corresponding mounting holes are provided, and the two locking fasteners 400 are installed in the corresponding mounting holes. Figure 5 and Figure 8As shown, the four locking fasteners 400 located at the top center are arranged with the top two fasteners 400 adjacent to each other and the bottom two fasteners 400 adjacent to each other. The top two fasteners 400 and the bottom two fasteners 400 are located in two mounting areas, with a detection channel between them. Therefore, there are two mounting holes. The top two fasteners 400 are installed in the same mounting hole, and the bottom two fasteners 400 are installed in the same mounting hole. The size of the mounting holes is adapted to the size of the two fasteners 400 to be installed. The two fasteners 400 are a single structure and are installed simultaneously. Compared to installing two fasteners 400 in two separate mounting holes, installing two fasteners 400 in the same mounting hole simultaneously reduces installation steps and improves work efficiency. Similarly, as... Figure 5 The four locking fasteners 400 located at the lowest point in the middle position are set close to each other, so that the four locking fasteners 400 are a single structure and installed in the same mounting hole, which can reduce the installation steps and improve work efficiency.

[0068] This embodiment provides a vessel including a loading area 100 and a side passage 200. The loading area 100 is equipped with lashing devices 300 and locking devices, and is designed using the design method for mixed loading of containers and vehicles as described above, thereby enabling mixed transportation of vehicles and containers.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
