  • 1. SHEDGUM GAS PLANT DEPARTMENT Engineering Division P.O. Box 7000, Dammam, Tel: ………… June 17, 200X RECOMMENDATION TO INSTALL SEALS AND ALARMS SUPERINTENDENT Engineering Division Reference: Our conversation on June 13, 200X I recommend that we install double seals on all of the Dammam Plant pumps. Furthermore, even when all of the pumps are fitted with double seals, I recommend that we install alarms that will sound whenever the inner seal fails. These actions are needed because we cannot risk releasing hydrocarbons into the air at the plant. Under current conditions, as a recent incident shows, gases can be released. This incident occurred at 08:30 on April 30, 200X. A cloud of ethane vapor was released from pump G. When pump G had been given a preventive maintenance (PM) check the previous day, all of the seals were found to be in good condition. The pump was returned to service at 07:30 on April 30, and one hour later the leak occurred. The cause of the leak was the failure of a mechanical seal on the pump. An examination of the seal showed a small crack in it, even though the PM check the preceding day had not revealed any signs of cracking. The problem was apparently caused by the rapid increase from room temperature to operational temperature when the pump was placed back in service after the PM check. If you would like to discuss this recommendation further, please call me at 577-9848. ZIYAD JAWABRA, Area Engineer Area Plants Maintenance Unit ____________________________________ SAG:hg
