51316-7117-Biocide Injection to Eliminate the Risk of Bacterial Growth and Corrosion Failure in Non Internal Coated Pressure Safety Valve from an Eocene Sub Centre at Partitioned Zone (Kingdom of Saudi Arabia and Kuwait). – A Case Study

The case study demonstrates different approaches towards what went wrong and why on pressure safety valve susceptible to MIC growth. The Eocene Sub Centre-1 Shipping Pump discharge header connected pressure safety valve (01PSV172) reported leaking from the body and POD requested Asset Integrity Division to conduct Root Cause Analysis with recommendation.

Consider the existence of mixed-mode failure in which one mechanism or mode of failure is predominant by microbiologically influenced corrosion (MIC) failures which cause leaks in process equipment and pipelines particularly in the oil and gas industry and prevention of Microbiological corrosion will avoid costly replacement of equipments and thus avoid leaks of gases and discharges of oil. Such failures can have catastrophic results in fire loss of life and reduction in production with consequential impact upon the economics of the operation. The case study demonstrates different approaches towards what went wrong and why on pressure safety valve susceptible to MIC growth. The Eocene Sub Centre-1 Shipping Pump discharge header connected pressure safety valve (01PSV172) reported leaking from the body and POD requested Asset Integrity Division to conduct Root Cause Analysis with recommendation. The PSV was found leaking through a perforation on the valve body caused by an internal corrosion found in discharge side of PSV and sample collected from internal valve perforated area to know the corrosion related to MIC In addition to that water sample collected to analyse physical chemical properties and as well as microorganisms. All the testing methods contributed to MIC Growth.
