The aluminum alloy materials are now mainly applied to small passenger ships,cruise ships and high-speed ships,and rarely used on large hull structures.With the upgrading requirements for shipping energy consumption index,emission reduction and safety of personnel life at sea,the International Convention for the Safety of Life at Sea proposes higher requirements on the stability of large passenger vessels and Ro/Ro passenger ships.Therefore,it is more important for the lightweight design of the superstructure of large passenger ships.In this context,it is expected to become a trend for the superstructure of large ships to use aluminum alloy with reinforced steel plates,a new green material.The study on the safety and economy of the design scheme of aluminum sheet with ribs in the superstructure of large passenger and Ro/Ro passenger vessels will be conducive to the formation of the construction industrialization of aluminum alloy sheet with ribs in the shipbuilding industry.This paper outlines the aluminum sheet with ribs in the superstructure of large Ro/Ro passenger vessels.
