Abstract
Unusual and repeated bladder ruptures of pulsation dampeners installed on two units ofCondensate Export Triplex Double Diaphragm Reciprocating Pumps and two units of GlycolCirculation Triplex Plunger Pumps had caused a platform in Malaysia Offshore sufferedfrom frequent unplanned production shutdown and loss of millions of Ringgit sincecommissioning These frequent dampener bladder ruptures started by causing excessivevibration and the situation was worsened due to unavailability of enough sparedampeners Without proper dampening of pulsation, HSE issue had also became a seriousconcern due to loss of primary containment (LOPC) from the leakage of broken pipingjointThis case study discusses how the problem was found to be caused by a combination ofseveral factors and was solved by utilizing root cause failure analysis and step-by-stepmitigations
