Abstract: A ship for transporting a coal slurry comprising a plurality of holds partitioned by transverse bulkheads, each of the holds being provided with a slurry inlet at an upper portion thereof and drain outlets each equipped with a filter and formed in at least one of surrounding walls defining the hold substantially over the entire height of the wall, each hold being provided outside thereof with a drain sump for collecting the slurry water drawn off from the hold through the drain outlets and drainage means for discharging the slurry water from the drain sump.

Abstract: A ship for treating a coal slurry comprising a pair of opposed trays disposed in the vicinity of the upper deck for causing the coal slurry supplied thereto to flow forward and delivering the slurry, a slanting dewatering screen disposed below each of the trays for dewatering the coal slurry delivered from the tray to separate a particulate coal fraction having relatively large particle sizes, and conveyors for transporting to a specified position on the upper deck the particulate coal fraction dewatered and falling off the screen.
