Summary
BSEE investigates partial power loss at the Appomattox platform during generator fuel switching. Failed UPS capacitors and undersized fuses disabled the fire and gas processor, preventing emergency generator starting. Bypassing the UPS restored this capability. No injuries or pollution were reported; the facility had not begun oil production.
