The invention discloses an installation precision control method of a C-shaped saddle of an LNG filling ship. The installation precision control method comprises the steps of manufacturing the C-shaped saddle and installing the C-shaped saddle. C-shaped saddle manufacturing comprises the following steps of S11, a precision design of the C-shaped saddle; S12, C-shaped saddle manufacturing; S13, datum line drawing; S14, precision detection; and S15, C-shaped saddle transportation. C-shaped saddle installation comprises the following steps of S21, C-shaped saddle arc center point determination; S22, datum line reinspection; S23, C-shaped saddle positioning; and S24, C-shaped saddle installation. The manufacturing precision and the installation precision of the C-shaped saddle are monitored inthe whole process in the manufacturing and installation stages so that an actual mounting position of the liquid tank in the cargo hold is adjusted, the liquid tank is supported and fixed, stabilityof a liquid tank installation system is improved, and operation safety of the LNG filling ship is guaranteed.

    本发明公开了一种LNG加注船C型鞍座的安装精度控制方法,包括C型鞍座制作及C型鞍座安装的步骤;C型鞍座制作包括以下步骤:S11、C型鞍座的精度设计,S12、制作C型鞍座,S13、基准线堪划,S14、精度检测,S15、C型鞍座运输;C型鞍座安装包括以下步骤:S21、C型鞍座圆弧中心点的确定,S22、基准线复检,S23、C型鞍座定位,S24、C型鞍座安装。本发明在制造及安装阶段对C型鞍座的制造精度及安装精度进行全程监控,从而调节货舱内液罐的实际安装位置,对液罐起到了支撑及固定作用,提高了液罐安装系统的稳定性,保证了LNG加注船的运营安全。
