The invention relates to the technical field of ships, in particular to a liquid cargo ship dangerous area avoiding method. The method comprises the following steps: (S1) cabin wallboards are assembled and welded to divide a cabin into a cargo oil bin, an isolation empty bin, a ballast tank and a cargo pump bin; (S2) the polishing and the flaw detection are performed on welding lines between the cabin wallboards; (S3) the airtight tests are performed on the cargo oil bin, the isolation empty bin, the ballast tank and the cargo pump bin; and (S4) isolation pieces are arranged at included anglesbetween the isolation empty bin and the cargo oil bin and between the ballast tank and the cargo pump bin in the height direction; the isolation empty bin is divided into an isolation empty bin mainbody and isolation cavities by the isolation pieces; and the isolation cavities are positioned at the included angles. The isolation pieces are adopted to divide the isolation empty bin into two parts, so that leaked oil is only positioned in the isolation cavities, a combustible gas checking device has no need to be arranged in the isolation empty bin main body, and inerting anti-explosion measures have no need to be performed on the bins to reduce the ship construction cost.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to a method for avoiding dangerous areas of tankers. Background technique [0002] For tankers carrying cargo oil or chemicals with a flash point not exceeding 60°C, due to the flammable and explosive characteristics of the volatilized oil and gas, in order to ensure the operation and installation of the ship, the classification societies of various countries classify certain areas of this type of ship as defined as a hazardous area. In addition to the cargo oil tanks carrying cargo oil, these areas also include those areas that are easily affected by the volatilized oil and gas of the goods. Among them, the cofferdams and ballast tanks adjacent to the cargo oil tanks are also dangerous areas. [0003] For adjacent cargo oil tanks, in addition to conventional compartments having a common bulkhead with cargo oil tanks, those compartments that do not have a common bulkhead with cargo o...
