Date of publication: 02 July 2018 Print

Omsk and Novosibirsk regional oil pipeline directorates (RPDs) affiliated with Transneft Western Siberia have held a comprehensive emergency response drill (CERD). The main purpose of the CERD was to check whether the employees of the branches’ business units are ready to promptly respond to emergencies occurring when operating oil and petroleum products trunk pipelines (OTPs and PPTPs).

At the CERD, Omsk RPD was represented by staff from operation sections, the chief mechanical engineering and chief power engineering sections, the plant control system (PCS) section. Under the drill’s plot, comprised of 10 scripts, a dispatcher of Barabinsk line operation dispatcher station (LODS) spotted a pressure drop in the line portion of the Omsk – Irkutsk OTP. Oil transportation was suspended. A patrol crew went to the incident site. Employees of the Central Maintenance Division (CMD) of Omsk RPD and the emergency line maintenance division (ELMD) of Barabinsk LODS promptly discovered a simulated oil release in the line portion of the OTP, contained it and took all the measures to eliminate the consequences. The event also included checking whether the personnel at Barabinsk LODS mechanical process equipment servicing site was ready to eliminate a gate valve flange connection failure. The Absence of Reliable Data from the Omsk – Irkutsk Line Portion script was practised within the PCS section. Altogether, the CERD at Omsk RPD brought together 58 employees of Barabinsk LODS, Barabinsk PS, and the CMD. The technical means included vehicles (a fire engine, a truck-mounted crane, a low bed truck) oil skimming equipment and materials, kits of protective personal equipment and tools. All CERD participants coped with their tasks by the prescribed deadlines.

Anzhero-Sudzhensk LODS hosted a comprehensive emergency response drill at Novosibirsk RPD. Pursuant to the drill’s scenario, a damaged manhole gasket in the first belt of VFRT-20000 No. 6 vertical steel tank entailed an oil spill. The DCC (district control centre) dispatcher decided to suspend the tank’s operation. The CMD and ELMD staff of the station took the set of measures required to eliminate the simulated emergency. Both practical and simulated performance of tasks was planned. Working in real time, the employees installed a mobile pumping unit, performed pressure testing of the assembled lines and a mandatory analysis of the ambient gas and air. Three more scripts were practised: Eliminating Malfunction of a Valve in a Spring Pressure Relief Valve, Troubleshooting of a Measuring Channel With a Sensor Featuring a Standardised Output Current Signal, Troubleshooting and Eliminating Malfunctions in the Case an Electric Drive for a PS Process Gate Valve Fails. Checking the staff’s potential victims saving and evacuating skills, as well as giving them first aid, has become a must for comprehensive ERDs.

A supervisory commission issued favourable conclusions in respect of the CERD held. The commission’s members highlighted the clear-cut and rational interaction between the units and divisions involved as well as full adherence to industrial, fire and occupational safety rules. As noted by Dmitry Khrychyov, Acting Chief Engineer of Transneft Western Siberia, employees of the units engaged have fully performed their tasks within the comprehensive ERD, as far as their professional skills and competencies were concerned.
