Embodiment 1

[0013] A cargo deck loading optimization method, obtained by finite element analysis and ship stability calculation of 46000DWT bulk cargo hold, by changing the average plate thickness of the side deck, the average plate thickness of the middle deck, the first, the second The size of the hatch covers of the second and fifth cargo holds optimizes the loading capacity of the cargo hold deck. The average plate thickness of the side deck is designed to be 22mm, the average plate thickness of the middle deck is designed to be 16mm, and the area of ​​the hatch cover of the first cargo hold is designed to be 20.26*17.33m 2 , the area of ​​the second and fifth cargo hatch covers is designed to be 21.52*19.12 m 2 . Through finite element calculations and ship stability calculations, the deck cargo is maximized, increasing the cargo capacity of operating ships by 11,000 tons.

Abstract

The invention discloses a cargo bay deck loading optimization method. According to the method, finite element analysis and ship stability are performed on a 46000DWT bulk cargo bay to obtain the mean thickness of a middle deck and the areas of first, second and fifth cargo bay covers by changing the mean thickness of a side deck on the previous basis, and therefore, the loading capacity of the cargo bay deck is optimized. The cargo bay deck loading optimization method is capable of confirming the loading weight of the ship deck on the basis of ensuring the existing ship structure design; the loading height of the deck is determined on the basis of ensuring the stability of the ship. The cargo bay deck loading optimization method is capable of increasing the ship cargo capacity to the utmost extent, and the key points of the method are the finite element calculation of the ship structure after loading on the deck and the calculation of the ship stability. The deck freight load is increased to the utmost extent by virtue of the finite element calculation and the ship stability calculation, and therefore, the cargo capacity of the ship in operation can be increased by about 11000 tons.

Description

technical field [0001] The invention relates to the field of ship loading, in particular to a cargo deck loading optimization method. Background technique [0002] With shipping costs increasing day by day, ship owners want ships to carry more cargo per voyage. How to increase the cargo capacity of existing ships has become a new research direction. Most of the bulk carriers currently in operation do not take deck loading into consideration when designing. Therefore, the research and development of cargo deck loading will effectively increase the cargo capacity of ships. The purpose of the research and development of cargo deck loading is to increase the cargo capacity of existing ships in operation, reduce ship operating costs, and increase the economic benefits of ship shipping. The goal of the research and development of cargo deck loading is to increase the cargo capacity of the ship without changing the existing hull structure design. The successful study of this sc...
