Description

Technical field:

[0001] The invention relates to the field of cargo hold structure design, in particular to a polar ship cargo hold structure and the ship thereof. Background technology:

[0002] Generally speaking, polar-class ships are ships that sail independently in polar ice areas. When moving forward, they will collide and rub against crushed ice on the sea surface, and bear the test of huge ice loads. Polar-class ships choose the appropriate polar class symbol to match their navigation area or operational requirements. The polar class symbol also indicates the ship's ice class operating capability and structural strength.

[0003] Generally, the structural layout of low-ice class ships is not much different from that of ordinary ships. Most of them resist the ice pressure generated by ice blocks by increasing the structural size in the ice-affected area. Low ice class refers to the Finnish-Swedish ice class (PC5, PC6, PC7), or the ice class of Russian Maritime Register (Arc4, Ice3, Ice2, Ice1). High ice class refers to the Finnish-Swedish ice class (PC4, PC3, PC2 and PC1), or the ice class of Russian Maritime Register (Arc6, Arc7, Arc8, Arc9). Because its ice-strengthened structure needs to meet the requirements of sailing in polar areas with ice thickness of more than 1.2 meters throughout the year, it has higher requirements for structural layout.

[0004] There is an urgent need for a polar ship cargo hold structure and a ship thereof, which can help solve the technical problem that the existing technology lacks a polar ship and the existing structure cannot adapt to the use environment when encountering huge ice pressure. Summary of the invention:

[0005] In one embodiment, the present invention provides a polar ship cargo hold structure, wherein the polar ship cargo hold structure includes a side outer plate and a side inner plate to form a space, and then a first horizontal girder of a side ballast tank and a second horizontal girder of a side ballast tank are arranged, which helps to solve the technical problem in the prior art that the existing structure cannot adapt to the use environment when a polar ship encounters huge ice pressure during navigation.

[0009] A plurality of inner hull longitudinal bulkhead longitudinals are arranged along the inner wall of the side inner plate and are spaced apart above the longitudinal spacing space.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0038] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0039] It should also be understood that, although the present application has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0040] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0041] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to determine the true intent based on the user's historical operations and to avoid unnecessary or redundant details that make the present application unclear. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but are merely used as the basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0042] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0043] At present, most of the ships operating in the market are low-ice class ships, and there is a lack of design experience for high-ice class polar ships. When high-ice class polar ships are sailing in polar areas, they are subject to huge ice pressure caused by thick ice layers, so the rationality and safety of the structural layout of high-ice class polar ships are required to be high. This paper reasonably arranges the structure of the ice zone reinforcement area to make the structure better resist the ice layer and avoid damage.

[0044] The present invention is a polar-class oil tanker with a high ice class. By combining a reasonable horizontal girder structure arrangement with the structure of the cargo hold area, the structural reinforcement area affected by the ice zone reinforcement range is minimized, thereby reducing the structural weight and realizing green shipbuilding.

[0045] The present invention provides a cargo hold structure layout for a high ice-class polar oil tanker, which makes the ice-strengthening structure of the cargo hold area more concise and optimized. With the most reasonable structural layout and reduced structural redundancy, the ship has the best ice resistance performance, is safest and most reliable when sailing in the polar ice area.
