一种新型移动泵下泵装置在FPSO上的应用

New Pump Descending Device of Mobile Pump Used on FPSO

液压潜没泵在FPSO货油系统中有着广泛的应用,因其灵活、安全的驱动方式在FPSO上有着不可替代的地位,布置方式一般采用一舱一泵的方式,为了防止在日常生产中液压潜没泵出现故障影响正常生产或者方便人员下舱检修,将舱内的液货通过移动式潜没泵外输或倒舱。而安全可靠的下泵装置是移动式潜没泵安装和使用的重要组件。文章结合南海“深海一号”半潜平台移动式潜没泵下泵装置的特点进行探究。

The hydraulic cargo oil pump is widely used in the FPSO cargo oil system and indispensable on FPSO due to its flexible and safe driving method,and generally arranged in a manner of one-tank-one-pump.In daily production,to prevent a failure of a submersible pump from affecting normal production or to facilitate tank maintenance of staff,liquid cargos in the tank are transferred outside or dumped through the mobile submersible pump,so that a safe and reliable pump descending device is an important component for installation and use of the mobile submersible pump.In this article,a summary made in combination with features of the pump descending device of the mobile submersible pump installed on the semi-submersible platform“Deep Sea No.1”in South China Sea may provide a reference for application of temporary submersible pumps in marine engineering in the future.
