Description

TECHNICAL FIELD

[0001] The present application relates to the field of overall design of a ship, in particular to a superstructure with optimized arrangement of a liquid cargo distribution board. BACKGROUND

[0002] The liquid cargo distribution board is one of the important equipment for loading liquid cargo on a liquefied gas carrier, and is a "heart" component in the loading of liquid cargo. However, the device is generally arranged in the superstructure main deck area of a very large liquefied gas carrier (VLGC\VLEC) in the conventional arrangement. Through research on the data of the shipbuilding industry, the liquid cargo distribution board of large liquefied gas carriers manufactured by advanced shipbuilding enterprises in Japan and Korea is arranged in the superstructure main deck area. Although this arrangement is simple for the shipowner to operate, it has a great impact on the overall shipbuilding cycle and delivery time. In view of the current global demand for large liquefied gas carriers, the shipowner is more willing to obtain the ship in advance to transport gas, and is more inclined to early delivery by the shipyard than operation. However, since the liquid cargo distribution board is arranged in the superstructure main deck, its base can only be arranged on the three segmented structures of the main deck. The installation of the liquid cargo distribution board must wait for the three segmented structures to be assembled into one body, and then the superstructure structure is hoisted into the dock. Due to the spacing limitation between the superstructure main deck bulkhead structure and the liquid cargo distribution board, the liquid cargo distribution board can be installed in place only after more than 40 days of various types of work construction. Moreover, since the installation cycle of the liquid cargo distribution board is the short board among all types of work, if the liquid cargo distribution board is moved to the superstructure A deck and completed during the superstructure assembly stage, at least 12 days of the current shipbuilding cycle of the liquid cargo distribution board arranged in the superstructure main deck is shortened, which greatly shortens the rental rate of the dock and creates favorable conditions for early delivery of the ship. However, the relocation of the liquid cargo distribution board involves related technical problems such as cabin arrangement, ship structure layer height requirement, radar mast and cable routing, air pipe and lamp arrangement, which cannot be solved simply by relocation. How to solve the above-mentioned comprehensive technical problems can solve the problem of arranging the liquid cargo distribution board on the superstructure A deck, which is a key technical problem that has been unable to be solved in the field of large liquefied gas carrier shipbuilding so far. SUMMARY

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present application is to provide a superstructure with optimized arrangement of a liquid cargo distribution board. The method deeply analyzes the cabin arrangement, ship structure layer height requirement, radar mast and cable routing, air pipe and lamp arrangement, and proposes corresponding solutions, so that the liquid cargo distribution board is installed during the superstructure platform construction and is completed before the superstructure is hoisted.

[0010] Preferably, the side of the gym close to the port side is provided with an engine room gangway, and a structural cabin is arranged above the engine room gangway, so as to facilitate laying of the cable and installation of the cable bracket to the cargo hold area.

[0011] Preferably, the layer height between the A deck and the B deck is raised as a whole, so that the net height H1 reaches 3100 mm, so as to meet the cable bending radius height, air pipe thickness, lamp thickness and liquid cargo distribution board height of the cargo control console on the B deck of the superstructure to the cargo hold area; the cargo control console is arranged in a cargo control room on the deck.

[0012] Preferably, the structural stiffeners on the hull structure around the liquid cargo distribution board room are all turned outward, so that the interior of the liquid cargo distribution board room is all a light coaming structure, preventing the liquid cargo distribution board from being scratched during pre-buried hoisting.

[0033] It should be noted that the drawings provided in the embodiments are only schematic and are intended to provide the basic understanding of the application. In the drawings, the shape, the number and the size of components are not drawn according to the actual implementation, and the shape, the number and the size of components in actual implementation can be changed arbitrarily, and the layout of components can be more complex.

[0034] As shown in Figure 1 , the present application provides a superstructure 1 for optimizing the arrangement of liquid cargo distribution board, the superstructure 1 comprises from bottom to top a main deck, an A deck, a B deck, a C deck, a D deck, a bridge deck, and a compass deck;

[0035] Referring to Figure 3 , a liquid cargo distribution board room 3 is located on the A deck, and the liquid cargo distribution board 2 is arranged in the liquid cargo distribution board room 3; the entire liquid cargo distribution board room 3 is closer to the port side relative to the ship's centerline, and this arrangement is conducive to the cable laying of the liquid cargo distribution board 2 to the cargo hold area 26; referring to Figure 4 , the cargo hold area 26 comprises an area above the main deck on the side of the superstructure close to the bow of the ship.

[0036] Referring to Figure 3 , the liquid cargo distribution board room 3 is provided with an independent air conditioning room 5 on the side close to the port, and the unit air conditioner 4 for air cooling of the liquid cargo distribution board room 3;

[0037] A gym 9 is located on the main deck and is arranged directly below the liquid cargo distribution board room 3, and the height H3 of the gym 9 is 2150mm. Since the space of the gym 9 is relatively large, it is necessary to ensure that the thick cable 27 below the liquid cargo distribution board 2 has sufficient cable 27 bending radius and laying turning space.

[0038] Referring toFigure 6 And Figure 7 The rear wall of the gym 9 needs to be partially opened to provide space for the laying of the power cable 27 from the liquid cargo distribution board 2 to the engine room area, and the cable 27 runs vertically through the gym 9. The cabin wall 20 is arranged on both sides of the cabin door 10 of the rear wall of the gym 9, so that the cable 27 from the liquid cargo distribution board 23 to the engine room area has enough space to lay, and there is enough space to weld the cable bracket 14 and the cable frame 15. The cable frame 15 is used to accommodate the cable 27, and the cable frame 15 is connected to the bulkhead through the cable bracket 14, and the cabin wall 20 covers the cable frame 15.

[0039] Further, the overall height between the main deck and the A deck is raised, so that the net height H2 reaches 3300mm, the purpose is to meet the bending radius height of the cable 27 from the liquid cargo distribution board 22 to the cargo hold area 26, the thickness of the air pipe 22, the thickness of the lamp 21, and the net height of the gym 9.

[0040] The overall height between the A deck and the B deck is raised, so that the net height H1 reaches 3100mm. The purpose is to meet the overall height arrangement of the cable 27 from the superstructure B deck cargo control console 24 to the cargo hold area 26, the thickness of the air pipe 22, the thickness of the lamp 21, and the height of the liquid cargo distribution board 22.

[0041] Further, refer to Figure 5 The structure reinforcing rib 28 on the hull structure around the liquid cargo distribution board room 3 is all turned outward, so that the inside of the liquid cargo distribution board room 3 is all light wall structure. The purpose is to prevent the structure reinforcing rib 28 from being easily damaged during the pre-buried hoisting of the liquid cargo distribution board 2.

[0042] Further, the gym 9 is provided with an engine room gangway 12 near the port side, and a structure empty cabin 23 is arranged above the engine room gangway 12, which is convenient for laying the cable 27 and installing the cable bracket 14 to the cargo hold area 26.

[0043] Further, refer to Figure 8 Due to the overall heightening of the superstructure 1, when the ship passes through the channel bridge, the radar mast 16 at the top of the superstructure 1 will be affected by the height, so a locally reversible radar mast 16 can be used. The fixedly connected satellite communication antenna 17 and satellite communication antenna base 18 at the top of the radar mast 16 can rotate in the vertical plane to lay down the satellite communication antenna 17 when interference occurs. The flange joint or split of the pipe can also be used for reversal, and personnel can directly operate at the top of the radar mast 16, as long as it is restored to place after passing through the channel bridge.

[0044] Further, the cable 27, the air pipe 22, and the lamp 21 are arranged as follows:

[0045] The cable bracket 14 is arranged above the liquid cargo distribution board room 3, and is connected to the lower surface of the B deck, and holds the cable 27 from the cargo control console 24 to the cargo hold area 26, and the air pipe 22 is arranged below the cable bracket 14, and is directly introduced into the liquid cargo distribution board room 3 by the unit air conditioner 4 in the separate air conditioning room 5, and the lamps 21 are arranged below the space near the air pipe 22. The cargo control console 24 is arranged in the cargo control room 25 on the B deck.

[0046] The height of the cable bracket 14 above the gym 9 needs to ensure that the thick cable 27 has a sufficient bending radius, and the cable bracket 14 is connected to the lower surface of the A deck, and holds the cable 27 from the liquid cargo distribution board 2 to the cargo hold area 26, and the surrounding wall plate is installed below the cable bracket 14, and the lamps 21 are installed on the surrounding wall plate.

[0047] The cable 27 from the liquid cargo distribution board 2 to the cargo hold area 26 passes through the cable bracket 14, and then passes through the cable frame 15 and the cable bracket 14 through the upper part of the front wall of the main deck, and is directly laid to the cargo hold area 26.

[0048] In addition, since the main deck is arc-shaped, cement dressing 19 needs to be laid on the surface to form a plane, and then the gym 9 is built on the plane. The duty dining room 6 is arranged on the left side of the separate air conditioning room 5, and the internal corridors 7 are arranged on each deck, and the crew entertainment room 8 is arranged on the right side of the liquid cargo distribution board room 3, and the medical room 11 is arranged on the right side of the gym 9.

[0049] Further, the process of positioning and welding the liquid cargo distribution board row to the liquid cargo distribution board base is carried out during the superstructure platform general assembly process, and not in the dock.

[0050] In summary, the superstructure of the liquid cargo distribution board arrangement provided by the application has many advantages compared with the traditional arrangement. In the past, the liquid cargo distribution board of a large liquefied gas ship was arranged on the main deck of the superstructure. According to the normal construction sequence, the engine room structure needs to be assembled completely, then the liquid cargo distribution board base and the cable frame are welded completely, then the liquid cargo distribution board is hoisted to the engine room assembly structure for concentrated pre-burying, then the superstructure is hoisted to the engine room assembly structure, then the superstructure structure is trimmed for the excess amount, then the outer periphery of the superstructure structure is welded and inspected, then the water baffle flat iron is welded, and so on. After about 40 days of these processes, finally, the liquid cargo distribution board row is positioned and welded to the liquid cargo distribution board base. These processes are carried out in the dock, which greatly affects the dock period.

[0051] The liquid cargo distribution board is arranged on the superstructure A deck, the positioning and welding process of the liquid cargo distribution board can be performed in the superstructure platform assembly process without being performed in the dock, and the construction can be completed at least 40 days in advance, the liquid cargo distribution board is moved from the traditional main deck to the A deck, the cables of the cargo compartment area equipment do not need to pass through the main deck through the engine room area, can be directly passed through the cargo compartment area from above the main deck of the superstructure, the cable length can be greatly shortened, and the material cost and construction amount are reduced. The operation period in the dock can be saved by at least 12 days, the shipbuilding period is further reduced by 12 days, and the production efficiency is improved. The application can be widely used in all large liquefied gas ships in the future.

[0052] As an innovative application of the above technical scheme, the optimization arrangement of the liquid cargo distribution board on the superstructure A deck can not only greatly advance the installation period of the liquid cargo distribution board, but also effectively shorten the construction period of the large liquefied gas ship in the dock, and greatly improve the shipbuilding efficiency. The technical method is easy for people familiar with the field to understand, can be popularized to the shipbuilding technical field of all large liquefied gas ships in the shipbuilding industry, and belongs to the first creation in the domestic and even shipbuilding industry.
