Abstract

PURPOSE:To prevent the outflow of fuel at collision and such by comprising a fuel tank with a side wall separated from a side outside plating to the inside, bottom wall separated from the bottom plating to the upward, hull transverse bulkhead, and required top wall. CONSTITUTION:At the bottom of a container ship, a fuel tank is comprised with a fuel tank side wall 4 separated from a side outside plating 3 to the inside, fuel tank bottom wall 4' separated from a bottom plating 3' to the upward, hull transverse bulkhead, and a required fuel tank top wall 5. The damage of the fuel tank can be prevented at collision by forming the fuel tank spaced at regular intervals from the outside plating and the bottom plating. As a result, the outflow of the fuel can be prevented at collision.
