Omsk ROPD of Transneft Western Siberia Conducts Emergency Response Drills at OTP Underwater Crossing

Date of publication: 05 February 2018 Print

Omsk Regional Pipeline Directorate (a branch of Transneft Western Siberia) held an emergency response drill (ERD) for its employees to review the topic of an oil spill on ice-covered water (localization and clean-up).

The ERD was conducted at the underwater crossing of the Omsk – Pavlodar oil trunk pipeline (OTP) over the river Om. The river is 50 meters wide at the point of the crossing; the maximum stream velocity is 0.28 m/sec. As per the scenario, for some unidentified reason a drop of pressure took place in the riverbed of the underwater crossing of OTP Omsk – Pavlodar. The transportation of crude oil was halted. On the dispatcher’s instructions a patrol crew moved out to inspect the OTP and stated a conventional spill of crude oil with an oil spot spreading downstream. As per the oil leakage prevention and elimination plan (OLPEP), crews of emergency line maintenance divisions (ELMD) and the central maintenance division (CMD) carried out all essential works to localize the conventional oil spill on the water surface and eliminate the consequences of the emergency.

“The personnel were to set up winter booms Rubezh-Zima 150 at the first and second localization lines. At the first line the workers set up a remedial line of booms, while at the second line they installed the main and standby booms. Overall, 54 people were engaged in the ERD: ELMD employees of the Omsk Region LODS, Omsk LODS, Moskalenki LODS, Tatarskaya LODS, Tatar Oil Pumping Station (OPS), CMD, a chemical testing lab crew, an outsourced fire crew and a security service,” said Deputy Director of Omsk Region LODS Aleksey Letushev.

At the main (second) line of booms ELMD specialists measured the thickness of the river ice to assess the safety if the personnel and the machinery were safe on the ice, made perpendicular ice cuts and set up booms. After mines were carved, skimmers and oil collection tanks were set up. Environmental monitoring was constantly performed at the site of emergency response and leakage elimination works.

As was noted by the ERD Head and Chief Engineer of Omsk ROPD Vladimir Shuvalov, the ELMD and dispatcher staff successfully coped with the tasks at hand. “The employees proved their readiness to quickly search for a conventional oil leakage spot, prevent emergency aggravation and to properly use the applicable technical facilities for a conventional crude oil spill localization and elimination. We kept within the set time limits and it took us slightly more than 3 hours to set up the boom lines,” he added.

As per regulatory requirements, emergency response drills on underwater crossings of oil trunk pipelines and petroleum products trunk pipelines are mandatory in summer and winter. The main goal of training the personnel to quickly respond to all kind of emergencies is to minimize emergency risks at hazardous industrial facilities and ensure high levels of environmental protection in the area of trunk pipelines of Transneft Western Siberia.
