PASSENGER SHIP OF WHICH THE SUPERSTRUCTURE IS EQUIPPED WITH AT LEAST ONE ARCH

摘要

PURPOSE: A passenger ship with one or more arches on a superstructure is provided to reduce component costs with a simple structure of a ship and to reduce the energy consumption of a ship required for propulsion by reducing the weight of superstructures. CONSTITUTION: A passenger ship comprises a main structure(2) of which boundary is limited by a hull(20) and an upper deck. One or more superstructures(3) are protruded on the main structure and are extended from a fore part to a tail part of the ship. Each superstructure comprises one or more arches(4). The arches are extended through the main structure. Both ends(41) of the arches are firmly coupled to the main structure to support at least a part of loads related with deflection thereof.
