采用理论分析和实船应用检验相结合的方法,对大连远洋运输公司的72000 DWT双壳体原油船航行过程中,油舱货油自然冷却过程进行分析研究.根据非稳态导热集总参数法建立油船油舱保温数学模型,研制了油船货油保温计算软件.通过实船应用比较,软件计算的保温时间和实际的保温时间最大误差为13%.
The natural cooling process of cargo oil in oil tanker during the sailing process of 72000 DWT double-hull tankers of Dalian Ocean Shipping Company was analyzed with the method of theoretical analysis and practical ship application test.Based on the unsteady heat conduction lumped parameter method The mathematic model of oil tanker thermal insulation was established, and the calculation software of thermal insulation of oil tanker oil was developed.Compared with the real ship application, the maximum error of thermal insulation time and actual thermal insulation time calculated by software is 13%.
