Abstract:
1. A frictional resistance reducing device of a ship, the frictional resistance reducing device comprising: a gas room provided in a hull to cross a longitudinal frame and to extend in a width direction of the hull; a scattering member arranged in said gas room to cross the longitudinal frame and to extend in the width direction; and an air supply pipe connected with said gas room, wherein air blows into said gas room from said air supply pipe, hits said scattering member and scatters in the width direction, and then blows from an air blowing hole provided in a bottom of said gas room into water, wherein a first opening is provided in a portion of said gas room on a port side from the longitudinal frame to connect an internal space of the hull and an internal space of said gas room, wherein a second opening is provided in another portion of said gas room on a starboard side from the longitudinal frame to connect the internal space of the hull and the internal space of said gas room, wherein a first lid is provided for said first opening, and a second lid is provided for said second opening, wherein a first part of said scattering member which is a part of said scattering member on the port side from the longitudinal frame, and a second part of said scattering member which is a part of said scattering member on the starboard side from the longitudinal frame are separable from said scattering member, and wherein said first part of said scattering member has such a size that said first part of said scattering member is possible to pass through said first opening, and said second part of said scattering member is such a size that said second part of said scattering member is possible to pass through said second opening.
