The invention discloses a method for prolonging the service life of an FPSO pipeline support, which comprises the following steps: comparing the inherent frequency fn of the floating production storage and offloading (FPSO) pipeline support with the ocean wind wave frequency f1 and the FPSO ship body vibration frequency f2, adjusting the structure of the floating production storage and offloading (FPSO) pipeline support, changing the inherent frequency of the whole pipeline support, and enabling fn to be far away from f1 and f2, the forced vibration of the pipeline support caused by wave and hull vibration is reduced, the alternating load of the pipeline support is reduced, the working time of the floating production storage and offloading device FPSO pipeline support on the sea is effectively prolonged, and the service life of the floating production storage and offloading device FPSO pipeline support is prolonged.
本发明公开了一种提高FPSO管线支架使用寿命的方法,该方法通过将浮式生产储卸油装置管线支架的固有频率fn与海洋风浪频率f1和FPSO船体振动频率f2进行比较,对浮式生产储卸油装置FPSO管线支架结构做出调整,改变整个管线支架的固有频率,使fn远离f1,f2所在范围,从而减小管线支架由波浪和船体振动引起的受迫振动,进而减小管线支架的交变载荷,有效地提高浮式生产储卸油装置FPSO管线支架在海洋上的工作时间,提高使用寿命。
