Ro-ro passenger ship

Abstract

The invention relates to the technical field of ships and discloses a ro-ro passenger ship. The ro-ro passenger ship comprises a left side board, a right side board, a first deck, a third deck, a fifth deck and a supporting assembly capable of being selectively supported between the third deck and the fifth deck, wherein the left side board and the right side board are arranged in parallel, and the first deck, the third deck and the fifth deck are sequentially arranged between the left side board and the right side board in parallel from bottom to top in the vertical direction; the first deck, the third deck and the fifth deck are all used for bearing goods. The supporting assembly selectively supported between the third deck and the fifth deck is arranged and used for supporting the fifth deck when the fifth deck is used for loading cargos, deformation of the fifth deck is avoided, reliability and safety of cargo loading of the fifth deck are guaranteed, meanwhile, cost is lower, economic benefits are better, and loading of goods on the third deck cannot be affected, and loading efficiency and the cargo capacity of the ro-ro passenger ship are guaranteed.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ro-ro passenger ship. Background technique [0002] A ro-ro passenger ship, also known as a lift-off ship, is a transport ship that uses a tractor to pull a semi-trailer or wheeled pallet loaded with boxes or other cargo directly into and out of the cargo hold for loading and unloading. The cargo carried by the ro-ro passenger ship enters and exits the warehouse through its own power and can carry passengers at the same time. It is mostly used for inland river ferries and medium and short-distance sea transportation. At present, the first, third and fifth decks of MSC ro-passenger ships are decks for loading vehicles. Since the middle part of the third deck does not have a well or room similar to other ro-ro passenger ships on the midline of the ship as the support for the fifth deck, after the According to structural calculation, the fifth deck will be deformed after loading v...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, in order to improve the strength of the fifth deck, it can be handled by adding an encrypted beam. Correspondingly, adding an encrypted beam will increase about 30 beams, increase the structural weight by about 157 tons, and increase the joints of the pipes on the beams by about 2 tons , and increase the number of about 100 electric lamps, which will result in an increase in cost, as well as an increase in the weight of the ship and an increase in the center of gravity, which is not conducive to the navigation of the ship

In addition, the transverse T-beam can also be encrypted, and the fifth deck can be supported by adding pillars in several places. Although the use of encrypted beams can be reduced, the pillars will hinder the passage of vehicles on the third deck and affect passenger rolling. cargo capacity of the ship
