Transneft Urals has held a comprehensive emergency response drill (CERD) on eliminating oil leakage from a tank, as well as eliminating failures in the equipment operation, at the Kaltasy line operation dispatcher station (LODS), the initial station of the Arlan Oil Pipeline Directorate (OPD).
The drill scenario included receiving a signal on simulated oil release through manholes of the tank with a volume of 20,000 m3 as a result of gasket damage. After notifying operational and dispatching units of the district and regional control centres, specialists arrived at the scene to inspect the tank.
After confirming the simulated leakage, employees of the tank farm operating section, emergency line maintenance division and central maintenance division of the Kaltasy LODS joined the effort to eliminate its cause and consequences. The simulated spill was degassed and contained, the manhole covers were dismantled for replacement of sealing elements and installed back. The simulated oil spill was collected in a short time.
The CERD programme included four more additional conditions: a stop valve failure, an automation system failure, a short circuit at a transformer substation, an incident at a tank filling station with a simulated petroleum products spill. All of them were completed according to the plan and within the specified timeframe.
74 people, using 12 pieces of equipment, took part in the drill. To ensure fire safety, a crew of fire rescue station No. 14 was involved. The sanitary and epidemiological standards were strictly observed. The drill was supervised by a commission, which included heads and specialists of sections and divisions of the Arlan OPD and Transneft Urals’ executive office. The commission members confirmed the readiness of the branch personnel to contain possible emergencies and eliminate their consequences.
