Application of risk based inspection(RBI)technology in large crude oil tanks
A great number of large crude oil tanks in national and commercial oil reserve bases are close to expiry date,but tank inspection is unable to schedule centrally in view of continuous production.By conducting risk based inspection(RBI)on a group of large crude oil tanks,failure mode and damage mechanism of the tanks were identified,tank risk assessment was made,RBI strategy for each tank was developed.The first inspection cycle of 12 large crude oil tanks was extended from 6-9 years to 8-13 years,reducing the frequency of tank inspection and improving inspection quality and efficiency.It is estimated to save RMB 137 million maintenance costs in 50 years target lifecycle.Compared to traditional inspection modes,the proportion of ma-intenance cost savings is as high as 28.64％with tremendous economic benefits.
