| 摘 要： | 为了提高某油库储油罐的利用效率，拟将富余的2座5X104m3外浮顶原油储罐改造为内浮顶柴油罐。基于此，分析了改造过程中需要处理的储罐缺陷，针对基础沉降和不均匀沉降，管壁椭圆度、垂直度和水平度，底板腐蚀情况，以及罐体各部位的钢板厚度进行相应检测，按照相关规范要求进行校核，确定各部位改造的具体技术要求。此外，通过调研分析，提出应用双向子午线网壳技术作为改造内浮顶的网壳顶盖。相关经验为后续储罐的改造修复提供了作业依据。（图3，表4，参7）

| Abstract: | In order to improve the utilization efficiency of oil tanks in a tankfarm, two surplus 5 ×104 m3 external floating roof crude oil tanks are proposed to transform into inner floating roof diesel tanks. In this regard, tank defects which need to be treated in the process of transformation are analyzed. In view of the foundation settlement and uneven settlement, the ovality, perpendicularity and levelness of tank wall and the steel plate thickness of each part of tanks are correspondingly detected. In accordance with relevant specifications, check and verification are conducted, and specific technical requirements for transformation of each part of tanks are determined. Furthermore, the two-way meridian net shell is taken as the net shell roof of inner floating roof. Related experiences provide a reference to the subsequent transformation and repair of storage tanks. （3 Figures, 4 Tables, 7 References） |
