Passenger ship main body structure resistant to stormy waves and unlikely to turn over

Abstract

The invention discloses a passenger ship main body structure resistant to stormy waves and unlikely to turn over and belongs to the technical field of shipping design and construction of traffic navigation passenger ships. The passenger ship main body structure can meet the demands for civil water transportation of passengers and solve the problems that the gravity centers of most passenger ship main body structures of different countries all around the world at present are too high, there are too many ship passenger cabin layers above ship full-load water lines in order to contain more passengers, and correspondingly the ships are likely to turn over. According to the structure, by reducing the height of a hull, reducing the passenger cabin layers, widening the hull, increasing underwaterpressure loading buoyancy chambers, lowering the gravity center of the hull, vertically designing the hull in an A shape with a narrow upper part and a wide lower part from the prow to the stern, designing two layers of passenger cabins, making a conical cockpit positioned above the passenger cabins, forming a catamaran and adopting other design schemes, the passenger ship main body structure isachieved.

Description

Technical field: [0001] The present invention "a main structural configuration of a passenger ship that is resistant to wind and waves and is not easy to capsize" belongs to the technical field of design and construction of passenger ships for transportation and shipping, and satisfies the purpose of water transportation for civil passengers. [0002] Up to now, most of the main structural configurations of passenger ships in various countries in the world are designed with a high center of gravity and high center of gravity, pursuing more passengers, and the part of the hull above the waterline with a full load has too many layers of cabins. The main structural configuration of the Oriental Star passenger ship Dimensions: 76.5 meters in length, 11 meters in molded width, 3.1 meters in molded depth, 2.5 meters in draft, 66 meters in main hull length, 12.4 meters in maximum width, 18.6 meters in height, 1.5 to 1.69 aspect ratio The ratio is 7.44, the length-to-width ratio of th...

Problems solved by technology

[0003] Up to now, most of the main structural configurations of passenger ships in various countries in the world are designed with a high center of gravity and high center of gravity, pursuing more passengers, and the part of the hull above the waterline with a full load has too many layers of cabins. The main structural configuration of the Oriental Star passenger ship Dimensions: 76.5 meters in length, 11 meters in molded width, 3.1 meters in molded depth, 2.5 meters in draft, 66 meters in main hull length, 12.4 meters in maximum width, 18.6 meters in height, 1.5 to 1.69 aspect ratio The ratio is 7.44, the length-to-width ratio of the main hull is 6, there are 4 layers of passenger cabins above the deck, and the approved passenger quota is 534. The size of its main structure makes the center of gravity of the ship obviously high and the draft is too shallow. Structural configuration design core parameter ratio (height-to-width ratio is between 1.5 and 1.69, ship height-draft ratio is 7.44) value is too large
