Transneft East, LLC conducted emergency response drills simultaneously with full-scale testing of the oil leakage prevention and elimination plan at Lena river underwater crossing (OTPUWC) of Eastern Siberia – Pacific Ocean (ESPO) Oil Trunk Pipeline.

The main purpose of the emergency response drill (ERD) was to mobilize the company`s divisions responsible for safe operation of the pipeline as well as to train the skills for prevention and elimination oil leakage at trunk pipelines` crossings through water barriers.

The plan for prevention and elimination of oil leakage at underwater crossings was developed by Omsk Regional Center of Transneft UW Service, JSC.

Employees of central maintenance divisions (CMDs) and the line maintenance division and teams of PS No. 14 Olekminsk took part in the emergency response drill. In total, 39 persons and 10 units of equipment, including water, were involved in the ERD.

According to the scenario, at 09:00 it was reported that the pressure became lower than acceptable level at Lena OTPUWC on 1,724.9 km of the line section of ESPO. Operating dispatcher of territorial dispatcher station simulated stoppage of oil transportation via the pipeline. After that, response groups started their work. The divisions` employees trained the algorithm of practical actions for localization of simulated leakage.

Oil-spill booms, seabed anchors, oil skimmers were installed on the river, and tanks for oil temporary storage were placed on the coast. Simulated oil leakage was completely localized in 4 hours from detection of oil show that corresponds to the standard term.

As Aleksandr Loboda, Deputy Director of the Branch of Neryungri Regional Oil Pipeline Directorate – a branch of Transneft East, LLC, noted, such drills allow to keep continued readiness of forces and means and to train the employees of divisions in respect of acting for localization and elimination of accidents and incidents on the sites of oil trunk pipelines. The drills were conducted in natural conditions simulating the real events. “Our task is to identify all possible failures in performance of operations on different stages. The past drills have shown good results”, he stated.
