Description

Liquid cargo ship

Technical Field

The invention relates to the technical field of ships, in particular to a liquid cargo ship.

Background

At present, international liquid cargo (hereinafter referred to as liquid cargo) is in vigorous demand for transportation, and with more and more environmental protection and effective energy efficiency regulations, the arrangement design requirements of all cabins in a liquid cargo ship are higher and higher. The stern of a liquid cargo vessel is typically arranged with a pump compartment (which is used to load mechanical equipment that controls the state of the ballast tank of the entire vessel), a fuel tank, a ballast tank, a cargo hold, and the like. So that the fuel tank is enclosed between the various tanks. The fuel oil contained in the fuel oil tank is generally heavy oil with high viscosity, and in the actual use process, the fuel oil tank needs to be heated to reduce the viscosity in order to facilitate the transportation and use of the fuel oil. However, the specific heat capacity of the compartments containing the liquid cargo, such as the ballast tank and the cargo compartment for the liquid cargo, is large, and the compartments having a large specific heat capacity absorb the heat of the fuel tank, thereby affecting the heating effect of the fuel in the fuel tank.

Therefore, a liquid cargo ship is needed to solve the above technical problems.

The embodiment provides a liquid cargo ship which can be used for carrying liquid cargo. The front, rear, left and right directions in fig. 1 are all the directions of the ship in the normal sailing state. As shown in fig. 1, the cargo tank vessel includes a plurality of cargo tanks, which are divided into a first cargo tank 10 and a second cargo tank 100, wherein the second cargo tank 100 is provided in plurality, the second cargo tanks 100 are mainly distributed in the midship and the bow of the vessel, and the first cargo tank 10 is arranged in the stern of the vessel. The cargo in the cargo ship is mainly loaded in the second cargo hold 100, and the first cargo hold 10 is normally empty, which means that the first cargo hold 10 is not loaded with cargo in a normal state, and the first cargo hold 10 is mainly used for temporarily loading cargo when the ship is parked at a dock. Alternatively, the first cargo hold 10 may be located entirely below the deck 70 of the liquid cargo vessel, or may be located partially below the deck 70 of the vessel and partially above the deck 70 of the vessel.

As shown in fig. 1 to 4, the stern of the cargo ship is further provided with a pump room 20, two side tanks 30, a communication passage 40, two fuel tanks 80, and two empty tanks 50. In which the pump compartment 20 is disposed below the first cargo compartment 10 and partially protrudes out of the first cargo compartment 10 in the fore-and-aft direction, i.e., the pump compartment 20 is partially located directly below the first cargo compartment 10 and partially located on the rear side below the first cargo compartment 10. The two liquid tanks 30 are located above the pump tank 20 and located on the left and right sides of the first cargo tank 10, the communication channel 40 is disposed behind the first cargo tank 10 and extends in the up-down direction, the communication channel 40 communicates the pump tank 20 to the deck 70, the two fuel tanks 80 are disposed above the pump tank 20 and located on the left and right sides of the communication channel 40, the two empty tanks 50 are disposed above the pump tank 20 and located on the left and right sides of the two fuel tanks 80, and each empty tank 50 separates the fuel tank 80 and the liquid tank 30 on the corresponding side.

In the cargo ship of the embodiment, the front side of the fuel tank 80 is the first cargo tank 10, but the first cargo tank 10 is in a normally empty state, the lower side of the fuel tank 80 is the pump tank 20, the left side and the right side of the fuel tank 80 are the communication channel 40 and the empty tank 50 respectively, and the empty tank 50 separates the fuel tank 80 from the liquid tank 30 on the corresponding side, so that compartments for containing liquid articles are arranged around the fuel tank 80 as far as possible, that is, the compartments around the fuel tank 80 are compartments with a smaller specific heat capacity, and therefore the fuel tank 80 can be well heated to ensure that fuel in the fuel tank can smoothly flow, and further, the oil for the whole cargo ship is ensured to be smooth. In addition, due to the requirement of the running speed of the ship, the size of the stern part along the left and right direction is generally in a gradually reduced state, so the buoyancy state (hereinafter referred to as the floating state) of the stern part is poor, and the pump cabin 20 is internally provided with a heavy machine, so the weight of the ship at the position of the pump cabin 20 is concentrated, and the buoyancy state of the stern part is also adversely affected.

Preferably, as shown in fig. 1, the liquid cargo ship further includes a cabin 90, and the cabin 90 is disposed at a rear side of the fuel tank 80. The engine room 90 is used for loading power components for driving the liquid cargo ship to run, so that no engine room for loading liquid articles is further ensured around the fuel oil tank 80, and the fuel oil in the fuel oil tank 80 can be smoothly heated to a state of smooth flow.

Preferably, the two empty chambers 50 are respectively in communication with the pump chamber 20. For the cabin on the ship, generally, an air intake and exhaust device, a detection device and the like which ensure constant pressure in the cabin need to be configured, in the embodiment, the two empty cabins 50 are respectively communicated with the pump cabin 20, so that the pressure states of the pump cabin 20 and the two empty cabins 50 are consistent, and the two empty cabins 50 and the pump cabin 20 can share one set of the air intake and exhaust device and the detection device, so that the manufacturing cost and the later maintenance cost of the liquid cargo ship can be reduced.

Preferably, as shown in fig. 2, the two empty compartments 50 are arranged symmetrically with respect to a mid-plane P of the liquid cargo vessel in the left-right direction. Therefore, the balance of the whole liquid cargo ship in the left and right directions is convenient to guarantee, and the design difficulty is reduced.

Preferably, the two tanks 30 are symmetrically disposed about a midperpendicular P of the lateral direction of the cargo ship, and the two fuel tanks 80 are symmetrically disposed about the midperpendicular P of the lateral direction of the cargo ship. Therefore, the balance of the whole liquid cargo ship in the left and right directions can be further facilitated, and the design difficulty is reduced.

Preferably, as shown in fig. 2, the communication passage 40 includes a ladder way 41 and a pump room booth 42. Wherein the stairway 41 extends along the up-down direction, the lower end of the stairway 41 is communicated with the pump chamber 20, and the upper end of the stairway 41 extends to the deck 70, so that an operator can conveniently enter the pump chamber 20 to install, overhaul and maintain the equipment in the pump chamber 20. The pump hangars 42 are provided on the deck 70 and cover the top of the runways 41, thereby shielding the entrances to the runways 41. It should be noted that the specific structure of the ladder way 41 and the pump chamber shed 42 may be any one of the prior art, and the specific detailed structure thereof is not limited herein.

Preferably, as shown in fig. 2, the rear side of the tank 30 shares the first bulkhead 31 with the front side of the corresponding empty tank 50. Since no parts to be protected are provided in the empty tank 50, the first bulkhead 31 is shared by the liquid tank 30 and the empty tank 50, so that the safety regulations of the vessel can be satisfied, and the cost of the cargo vessel can be reduced.

Preferably, as shown in fig. 2 and 3, the side of the tank 30 near the vertical plane P in the left-right direction of the cargo ship shares a second bulkhead 32 with the left or right side of the first cargo tank 10. Since the first cargo tank 10 is normally empty, the first bulkhead 31 shared by the liquid tank 30 and the first cargo tank 10 can satisfy the safety regulations of the ship. The side of the tank 30 remote from the mid-plane P in the lateral direction of the cargo vessel constitutes the hull 33 of the cargo vessel, the hull 33 being generally streamlined. The distance between the first bulkhead 31 and the outer hull 33 needs to be guaranteed to be more than two meters, based on the requirements of the ship's safety, so that the first bulkhead 31 runs roughly in line with the outer hull 33. Preferably, as shown in fig. 2, the second bulkhead 32 is formed by splicing a plurality of flat plates, so that the difficulty in manufacturing the second bulkhead 32 can be reduced, and the internal space of the first cargo compartment 10 can be more regular, thereby facilitating the storage of cargo.

Preferably, the two tanks 30 in this embodiment are fresh water tanks. The ballast tanks 60 are typically provided on the left and right sides of the cargo hold, and the embodiment of the invention provides the liquid tank 30 as a fresh water tank, which not only provides ballast but also provides fresh water for the supply vessel. Therefore, the spatial arrangement of the position of the liquid cargo ship for arranging the freshwater tank can be more flexible.
