Narrative
At 09:55, an enterprise employee reported a possible leak on c19. At approximately 14:00, after further investigation and site excavation, it was confirmed that the spill volume exceeded the reporting criteria and appropriate notifications were made. A plidco clamp was temporarily installed until a cutout is done.The sample will be sent to a lab for metallurgical analysis. Supplemental update: the metallurgical report concluded the following; leak was a result of external corrosion at the 6 o'clock position due to aqueous corrosion. Enterprise will continue to utilize corrosion inhibitors in addition to maintenance pigging to prevent recurrence of internal corrosion. Corrosion coupons are in place and monitored twice per calendar year in an effort to detect when corrosion rates exceed the 1 mil per year (mpy) threshold and will take corrective actions upon discovery of any corrosion coupon exceeding 1 mpy to mitigate the corrosion. The affected segment referenced in this report was replaced and is currently in service.
