摘要
为了解决超大型油船压载泵、货油泵透平对中安装作业问题,在深入实际调查研究的基础上,提出总段安装的工艺方法,即将透平对中安装作业阶段由船坞阶段提前至总段阶段实施,利用合拢管设计制造系统制作合拢管,辅之于全过程的控制手段以确保安装精度。经实船安装检验,证明此方法可降低劳动强度,优化作业环境,提升安全系数,缩短船舶建造周期。
In order to solve the installation problem of ballast pump turbine and cargo oil pump turbine of VLCC,the installation method in block stage is put forward based on the actual investigation and research.The installation and alignment of turbine is advanced from docking stage to block stage and the closure pipes are made by closure pipe system.The precision control method is adopted in the whole process to ensure the installation accuracy.After the installation inspection of real ships,it is proved that the labor intensity can be reduced,the working environment is improved,the safety factor is enhanced,and the construction cycle is shorten.
