Transneft Central Siberia Starts Preparation of Operating Facilities for Floods

Date of publication: 10 March 2020

Transneft Central Siberia’s specialists have started preparing the company’s facilities for operation during spring floods.

The purpose of the activities held until 31 March is to ensure reliable operation of pipeline transportation facilities in Tomsk and Kemerovo Regions during spring floods.

Sections of the Aleksandrovskoye – Anzhero-Sudzhensk and the Igolsko-Talovoye – Parabel oil trunk pipelines (OTPs) vulnerable to scouring are being monitored. Pipeline sections, communications facilities and route power line pylons in the areas that may be flooded are being additionally strengthened.

The company’s specialists are performing stop valves’ seasonal maintenance which includes checking them for complete opening and closing. They are also organising meltwater drainage from the valves.

Great attention is paid to the preparation of the oil pipelines’ crossings with rivers and small watercourses: pipeline telemetry systems are being checked, and marker posts are being inspected and repaired at OTPs’ underwater crossings. To prevent possible jams and water level rise in the areas of intersection with water obstales, it is planned to carry out debris and waste removal events.

In order to ensure reliable and accident-free operation of oil pipelines during the flood period, special-purpose vehicles, a supply of fuel and lubricants, oxygen and propane, as well as equipment and materials necessary for quick response to possible emergencies, has been organised at temporary base stations.

According to the estimates of the centre for hydrometeorology and environmental monitoring of Tomsk Region, the spring flood will begin in the first half of April. Preliminary analysis of hydrological conditions suggests that river breakup will occur three to six days earlier than on average. More accurate forecasts will be made at the end of March.
