Novel cross-sectional structure of ore carrier

Abstract

The invention discloses a novel cross-sectional structure of an ore carrier. The structure comprises an upper deck, planking and an outer bottom plate, wherein a cargo hold longitudinal bulkhead and acargo hold double-layer bottom are arranged between the upper deck and the outer bottom plate, the amidship postion of a hull has the largest molded breadth which is B meters, the amidship postion ofthe hull has the largest molded depth which is D meters, and the horizontal vertical distance S from the cargo hold longitudinal bulkhead in a deep waterline to the planking is 0.18B meters-0.25B meters; the cargo hold double-layer bottom adopts an upward inclined bottom at the position close to the longitudinal bullhead, and the grade included angle theta between the inclined bottom and the horizontal plane is 35-47 DEG C; and the minimum height H of the cargo hold double-layer bottom is 0.1D meters-0.15 D meters, and the span L of the lowest position of the cargo hold double-layer bottom is0.28B meters-0.65B meters in the ship breadth direction. According to the structure, the requirement on structural strength of the hull under standards and conventions and various loading conditionscan be met, the usage amount of steel and the manufacturing cost of a ship are not increased, the large hold capacity can be effectively provided in the length range of the ship cargo hold, and the good operation economy of the ship is ensured.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a novel cross-sectional structure of an ore ship. Background technique [0002] Most of the traditional ore ship types currently on the market are designed and developed according to the high-density characteristics of iron ore. Under the same ship type, their cabin capacity cannot meet the needs of low-density bauxite transportation. Facing the market demand, and at the same time guaranteeing the operating economy of the whole life cycle of the ship operating on different routes and different types of cargo, it is extremely important to design and develop an ore carrier with a large capacity as the goal. Contents of the invention [0003] The object of the present invention is to provide a novel cross-sectional structure of an ore ship aiming at the requirement that the traditional cross-sectional structure cannot meet the target design. [0004] In order to achieve the above o...
