  • Patent number: 4481898
    Abstract: A slurry carrying ship is characterized by hollow drainage posts provided in each cargo hold beneath the hatch at locations close thereto. Water passages are formed in the interior space of each post which is provided on its side walls with vertical rows of drainage ports and filters attached to the respective ports. Slurry water passes the drainage ports and the water passages and discharges through drain pipes provided at the lower end of the post. These drainage posts, because of their locations, can effectively drain water from coal slurry while reliably supporting the upper structures.
