Flexible structure air pipe of ship

The invention discloses a flexible structure air pipe of a ship. The flexible structure air pipe is arranged below a vehicle deck of a roll-on roll-off ship. The pipe body comprises a transverse pipesection and a vertical pipe section; the transverse pipe section is fixedly arranged at the bottom of a vehicle deck; the upper end of the vertical pipe section is fixedly connected to the transversepipe section; an air port is formed below the transverse pipe section; the pipe wall of the transverse pipe section and the pipe wall of the vertical pipe section are both ribbing plates; the ribbingplate comprises a plate-shaped body, a plurality of grooves are formed in the plate-shaped body, and the grooves are linearly distributed along the plate-shaped body; the grooves are parallel to eachother; the vertical distance from the bottom of the groove to the plate-shaped body is less than 50mm; the groove of the ribbing plate of the transverse pipe section is perpendicular to the length direction of the transverse pip
