ABSTRACT In a device for receiving leaking liquid for use in a ship carrying low temperature liquid or corrosive liquid in self-standing tanks, a frustoconical, umbrella-shaped leaked liquid diverting means is disposed around the root of a tank supporting block of the self- supported tank so as to direct liquid, which has leaked from the tank, to a heat insulating and protective member or a reservoir which is mounted below the outer periphery of the leaked liquid diverting means. This prevents the extremely low temperature liquid or corrosive liquid from directly contacting the bottom of the ship's hold. The problem the invention seeks to overcome is damage to a ship's structural steel caused by highly corrosive or extremely low temperature liquids which comprise the ship's cargo. Prior to this invention the alternatives were to either construct a ship of expensive special steel or provide a double insulating jacket. Both of these alternatives are extremely uneconomical. The present invention provides a low cost, efficient alternative.
