The invention provides a B-type independent liquid cargo compartment leakage liquid cargo leading-out structure. A liquid cargo compartment exists in the ship body. The lowest point of the bottom surface of the liquid cargo compartment is provided with a vertical flow guiding pipe. The upper part of the flow guiding pipe is provided with a plurality of flow guiding holes along the circumferentialdirection of the flow guiding pipe. Leakage liquid cargo flows into the flow guiding pipe through the flow guiding holes. The inner bottom of the ship body is provided with a liquid collecting trap. The flow guiding pipe extends into the liquid collecting trap. The flow guiding pipe is divided into an upper pipe and a lower pipe. An explosion plate is arranged between the upper pipe and the lowerpipe. The leakage liquid cargo leading-out structure according to the invention can ensure safety of the ship body structure on the condition of liquid cargo leakage in the liquid cargo compartment, thereby preventing direct contact between the liquid cargo and the ship body structure, and furthermore effectively collecting and processing the leaked liquid cargo.
