内河船舶舱底水量的统计分析及确定

Statistical Analysis and Determination of Volume or Bilge Water for Inland Ships

分析论述了现有的以船舶总吨位确定舱底水量方法的不足，提出了以船舶总功率确定舱底水量的新观念。经对３８艘内河船舶长达一年的舱底水量的大量数据统计测量和回归分析，得到了估算舱底水量的经验公式。该公式可较真实地确定舱底水量，为选择设计船舶油水分离设备或污油水舱柜时提供参考。

The shortcomings of the traditional method for determining the volume of bilge water of a ship are discussed. A new method to determin the bilge water according to the total power of a ship is presented in this paper. Numerous data of the volume of bilge water for 38 inland ships travelling in inland rivers during one year have been measured. Based on the regression analysis of the data,a empirical formula is given. The formula can be used not only for calculation of the volume of bilge water,but also for design of the oily water separating equipment or the oily water tank.
