Transneft Kama Region held a comprehensive emergency response drill (ERD) to eliminate a simulated oil spill in the Volga River, at the underwater crossing of the Kholmogory – Klin oil trunk pipeline (OTP) in the responsibility area of Kazan Regional Oil Pipeline Directorate (RPD).
Under the drill scenario, an operator of Kovali line operation dispatcher station (LODS) detected a pressure drop at the Kholmogory – Klin oil trunk pipeline and notified the Kazan RPD dispatcher of a simulated emergency. After consultation with the Company’s chief engineer, it was decided to stop oil pumping via the OTP. Patrol crews of Kovali and Studenets oil pumping stations promptly arrived at the simulated emergency site.
Under the drill script, inspection of the damaged oil pipeline section helped to detect an oil release from the OTP onto the water surface due to loss of containment in the longitudinal weld. The simulation emergency site was fenced off with a special tape and cordoned off by security officers.
The oil spill was contained using boom lines; the oil-containing film was mechanically removed from the water surface using oil skimmers. Specialists of the environmental analytical laboratory took water and soil samples to monitor ingress of contaminants.
The simulated oil spill was eliminated by emergency response crews of Kovali, Studenets, Tingovatovo oil pumping stations, Lazarevo LODS, the Central Maintenance Division of Kazan RPD, and the professional emergency rescue team (PERT) of Transneft Kama Region. The drill brought together 107 persons, 60 pieces of equipment and vehicles.
The concerted actions of all teams and the displayed high level of professional training enabled the personnel to cope with the simulated emergency without exceeding the prescribed deadlines, Eduard Ishalin, Deputy Chief Engineer – Head of Occupational Safety and Operational Control Directorate of Transneft Kama Region, said.
