Accident Classified As: Reportable Quantity
Power failures due to weather (Tropical Storm Cindy) caused various releases from Motiva sources; led to total loss of electrical instrument air compressors and the loss of several steam boilers that caused the shutdown of the HCU and RCCU process units. A voltage sag caused the Coker processor to shut down which resulted in a flaring event.
Motiva claims that this was not preventable because of the unforeseeable weather conditions.
