The import of the sawdust in China mainly depends on sea transportation, and the demand of the sawdust boat as a bulk cargo boat special for transporting bulk sawdust raw materials is increased in recent years.
The cross section of a typical bulk carrier is characterized in that: the bottom adopts a double-layer bottom and bottom side cabin arrangement form; the upper part is provided with a main deck and a top side cabin structure; main ribs in the form of transverse frameworks are uniformly arranged on the side to connect the bottom side cabin and the top side cabin; a hatch enclosing wall is arranged around the cargo hatch area.
The traditional cross-section design of a typical bulk carrier usually considers the variety diversity of the loaded goods, including light goods (usually not more than 1 t/m) 3 ) With heavy goods (usually about 3 t/m) 3 ) The whole cargo hold has moderate volume and relatively small profile depth; meanwhile, a top side tank is arranged to serve as a water ballast tank to adjust the center stabilizing height and the rolling period of the ship, but the top side tank occupies part of the tank capacity.
The density of wood chips is about 0.25 to 0.47t/m 3 More capacity is required than for a heavy load of equal mass. The relatively small depth of a typical bulk carrier type, with a top side tank design, becomes a major factor limiting the tank capacity.
Compared with a typical bulk carrier type, the wood chip carrier has the characteristics of single cargo carrying type, light cargo density, relatively large cargo hold volume requirement and the like, and the cross section design form of the traditional bulk carrier cannot well meet the cargo loading requirement.
