Narrative
The wilbreeze pump station unit# 2 was shutdown and isolated to conduct maintenance on the pump seal. While dcp employees were removing the bearing coupling, a flashfire occurred at 13:32 that was detected by the fire eyes detection system and triggered the esd which caused the wilbreeze pump station shutdown. The root cause was not having an adequate procedure while heating a mechanical component with a torch to remove or install bearing or hubs. The procedure has been revised to include guidance that all tubing must be connected and left intact while removing or installing the bearing coupling. The training will be conducted for field employees based on the new revised procedure.
