A range of consistent measures allowed Transneft Far East to cut energy consumption per tonne of pumped oil.
Oil transporters arrived at an optimal way of reducing the industrial costs.
In November the external audit confirmed that the energy management system of Transneft Far East complies with international standards (ISO 50001:2011). Transneft Far East is the company charged with operating the second phase of oil trunk pipeline Eastern Siberia – Pacific Ocean (ESPO-2).
The audit revealed
It is here that most up-to-date energy efficient technologies are used, which enable massive reduction of industrial costs.
Assessing the company’s operations, the auditors took note of some innovative approaches used. Among them is the cleaning of oil trunk pipelines from paraffin deposits, using optimal crude oil pumping regimes, installing the navigation system GLONASS at transportation facilities.
The Company’s specialists also focus on heightening the equipment performance characteristics and on outfitting the buildings and installations with energy-saving lighting fixtures. The whole of it enabled the reduction of electric power specific consumption, including per tonne of pumped crude.
Transneft Far East was rather quick in implementing a range of energy efficiency measures, since all facilities of the second phase of the oil trunk pipeline Eastern Siberia – Pacific Ocean were designed and built using state of the art technologies and materials, whereas new technical and managerial decisions are called to make the most of cutting-edge technologies.
Million a month
A pipeline company can save huge amounts of energy if the gigantic main line pumps of oil pump stations each consuming the average of 12 million kWh start saving power as well. In the past, whenever it was necessary to lower pressure in the oil main, they partially blocked the pipe with a shutoff valve, while the pumps continued working at full throttle. Modern mechanisms installed at ESPO-2 stations may operate with the capacity required at a given moment, creating the pressure needed; hence remarkable savings on the energy consumed.
Savings are also achieved due to special operational regimes of main line pumps, specifically developed for Transneft Far East by a specialized institute.
“To reduce power consumption at these regimes, rotation speed of the pump unit is raised to maximum possible levels and, as a result, the number of pumps at the entire technological section can be diminished,” says Ruslan Panteleev, head of the technological regime service.
Another cost optimization strategy is minimizing friction inside the pipeline. The point is that flowing crude oil exudes heavy hydrocarbon compounds deposited on inner walls of the pipe; these can notably decrease the pipe diameter with time. To preclude pipe choking, special mechanisms outfitted with scrubs or scrapers are injected into an oil pipeline every quarter.
One OPS consumes about 35 kWh of electric power monthly only for lighting purposes, but the use of LED bulbs cut this consumption by 80%.
“The pipe is cleaned from paraffin-like agents by means of batching pigs ensuring the standard flow area of the pipeline and reducing the handled medium flow resistance,” explains Denis Lipovtsev, head of OPS-38.
To cut the transportation costs, the Company successfully implemented the space monitoring system GLONASS, with all trucks and cars, buses and specialized machinery equipped with its customer sets. Thanks to this arrangement, it is possible to have an idea of the entire motor traffic and fuel discharge.
Implementing GLONASS at the facilities of Transneft Far East allowed the optimization of transportation routes, the exclusion of idle runs and down time of vehicles. And to be sure, besides the anticipated effect (money savings), the global navigation system enhanced the road traffic safety.
About the lights
All buildings and installations of the pipeline system ESPO-2 are ranked among high risk facilities and during the dark hours they must have proper lighting. At least 3,000 lamps are needed for eight oil pump stations, two oil pipeline directorates, linear operational sections, three central repair services, two industrial service bases and the administration and amenity building in Khabarovsk. Today only LED bulbs are used at these facilities.
“Their luminous power is comparable to that of incandescence lamps, but their service life is three times longer – up to 50,000 hours,” says Sergey Galetsky, head of the energy equipment service section at OPS-34. “And unlike other lamps, such fixtures have no adverse environmental impact.
But their main advantage is surely great power conservation. While one oil pump station is in need of about 35,000 kWh only for lighting purposes, the use of LED bulbs lowers this consumption by 80% to 7,000 kWh.
The Energy Saving Programme of Transneft Far East does not engage only specialists of respective services. Every employee who timely puts off the lights; plugs out all appliances and gadgets at his/her workplace, turns off office and indoor climate control equipment – can save plenty of energy throughout the year. With this target in focus, the Company constantly trains its personnel in the art of energy management: both the Company’s employees and representatives of contractors are introduced to the fundamentals of the Company’s energy policy.
A special workgroup for energy management implementation monitors and analyzes the use of fuel and energy resources, keeping track of the execution of various organizational and technical policies.
All consistently implemented energy conservation policies yield tangible results: in 2015 Transneft Far East saved more than 48 million kWh of electric power, roughly the annual lighting requirements for such a city as Khabarovsk.
