Professionals of the Krasnoyarsk Regional Oil Pipeline Directorate (a branch of Transneft Western Siberia) completed an emergency response drill (ERD) at the underwater crossing of the Omsk-Irkutsk oil trunk pipeline (OTP) over the Kan River. The company practiced primary actions of the staff to pursue containment and elimination of the conventional oil release to the water surface under ice.
Under a drill scenario, an emergency pressure drop was recorded at the Kan River underwater crossing of the Omsk-Irkutsk OTP (OTPUWC). A district control centre (DCC) operator remotely stopped the oil transportation. A patrol crew of the emergency line maintenance division (ELMD) from Poima pump station moved to inspect the site and elucidate the pressure drop causes.
The multiline UWC of the Omsk-Irkutsk OTP crosses the Kan River, a right-handed tributary of the Yenisei River. The tributary is maximum 300 metres wide and 6 metres deep. In winter the ice thickness varies from 0.5 to 1.2 metres. During inspection the patrol crew discovered a conventional oil release to the water surface. Primary security measures were taken – water sampling, valve closing checks, fencing off the conventional incident site. A team of the Poima PS security division maintained the access control mode. The patrol team reported its actions to the operator of the RPD district control centre.
As per the emergency oil spill response plan (OSRP), two lines were mounted on the Kan River to contain and eliminate the conventional spill. ELMS crews of the Poima PS and the Rybinskaya line operation dispatcher station (LODS) performed emergency recovery work at the Omsk-Irkutsk OTPUWC, cut the slots and channels in the ice-covered river surface, mounted the boom line and deployed the oil-skimming equipment. The environmental (air and water pollution) monitoring was conducted by a chemical analysis laboratory team of the Krasnoyarsk RPD analytical laboratory. The volunteer fire brigade (VFB) provided the fire protection. Subject to the ERD scenario, the professionals also practiced the input “A man falling into the water at the containment boundary No. 2 of the Kan River OTPUWC”: saving a person from the water, premedical first aid using a cardiopulmonary resuscitator, an injured evacuation by an ambulance vehicle.
Overall, the ETD employed some 60 staff members and almost 50 vehicles, including dedicated road vehicles and technical aids (oil skimmers, booms, oil collection and temporary storage tanks, channel heating tents).
The emergency response drills for emergency oil spill containment and elimination are crucial for industrial safety of Transneft Western Siberia. The main target of the industrial safety is to protect the company’s potential hazardous facilities from natural and man-made catastrophes. Apart from ERD, the tabletop, plus firefighting and tactical drills are held at Company’s facilities, in line with the master plan of civil defence, emergency prevention and response events.
