However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.

In the related art, the LNG container carrier mainly adopts an environment-friendly technology, so that the emission of carbon dioxide is reduced. But inside the cargo compartment, the deck is not uniform in length, which compresses the interior space of the cargo compartment. For example, 11500 TEUs (Twenty feet Equivalent Units, standard containers) may be loaded with the next 11500 standard containers 600. Under the main deck, the length occupied by the two decks is about 24.4m, the length occupied by the three decks is about 38.9m, the length occupied by the four decks is about 30.9m, the lengths of the three decks are different, the longer decks limit the placement of containers, the longer decks occupy the space in the cargo hold, the space of the cargo hold is difficult to fully utilize, and the loading amount of the loaded containers is reduced.

To this end, and referring to fig. 1 and 2, the present application provides a hull structure that may be used to transport containers 600, as well as other cargo. The hull structure includes: a hull 100 and a main deck 210, the main deck 210 being provided on the hull 100, the hull 100 being understood as a hull; the upper surface of the main deck 210 is relatively flat, enabling a larger load platform to be formed, which may be used to load the container 600, the load flat formed by the upper surface of the main deck 210 being generally open.

The hull structure further comprises two decks 220, three plates 230 and four decks 240, wherein the two decks 220, the three plates 230 and the four decks 240 are sequentially arranged below the main deck 210 at intervals, and generally, the interval distances among the main deck 210, the two decks 220, the three plates 230 and the four decks 240 are equal, and the interval height among each deck can be adjusted according to design requirements. The side of the two deck plates 220, the three deck plates 230 and the four deck plates 240 remote from the front end of the hull 100 form the cargo tank 101 with the rear end of the hull 100. It will be appreciated that in addition to being able to load containers 600 on the main deck 210, the cargo holds 101 below the main deck 210 are also able to load containers 600. The container 600 has substantially the same outer shape and size and is rectangular. The two decks 220, the three decks 230 and the four decks 240 are flush at the end of the side facing the cargo space 101, and the formed cargo space 101 is also more regular in shape, reducing the number of protruding decks and fully utilizing the space size of the cargo space 101.

In the present application, below the main deck 210, the side of the two, three and four decks 220, 230, 240 remote from the front end of the hull 100 forms a cargo hold 101 with the rear end of the hull 100. The two decks 220, the three decks 230 and the four decks 240 are flush with the end of the side facing the cargo space 101, so that the protruding decks are reduced, the shape of the cargo space 101 is more neat, the space in the cargo space 101 is increased, and the boxing amount of the container 600 is improved.

Moreover, the loading capacity of the container 600 of the cargo compartment 101 is increased, the whole center of the ship body can be sunk, the gravity center is more stable, and the sailing stability of the ship body is improved.

To further increase the loading of the container 600, the length designs of the two deck 220, the three deck 230 and the four deck 240 may also be equal. Cargo holds 101 are provided at both front and rear ends of the two decks 220, and it is understood that the front ends of the two decks 220, the three plates 230, and the four plates 240 are flush by the equal lengths of the two decks 220, the three plates 230, and the four plates 240.

The host 300 is disposed at the bottom of the hull 100, extends upward, and sequentially penetrates through the third host region 241, the second host region 231, and the first host region 221. The opening areas of the first host region 221, the second host region 231 and the third host region 241 may be the same, or may be adjusted on different decks of each layer according to the structure of the host 300, so that the deck area of each deck may be fully utilized.

The main power of the hull structure is basically from the main machine 300, and the hull structure further comprises a plurality of power components which are respectively arranged on the two deck 220, the three deck 230 and the four deck 240 and are arranged around the main machine 300.

The host 300 is controlled by the power components. While disposing the power components around the host 300 can reduce cabling, and can be connected to the host 300 in a short distance, completing control of the host 300.
