BAKU, Azerbaijan, Mar. 30
By Klavdiya Romakayeva - Trend:
Maintenance and repair work was carried out on the gas pumping units of the compressor stations at the assembly points No. 2, 3, 6 of the Kukdumalok complex of the Mubarek Oil and Gas Production Department using their internal capabilities, Trend reports citing Uzbekneftegaz JSC.
According to the information, the main task of these compressor stations is to pump low pressure natural gas coming from wells by increasing the pressure to compressor stations No. 1, 2, 3 to the head structure of the Kukdumalok complex.
It was noted that the shutdown of one of these stations will lead to a reduction in natural gas production by about 1 million cubic meters per day.
Thus, in order to prevent a reduction in the volume of natural gas, a phased operational implementation of routine maintenance and repair work is required at the gas pumping units of the stations of the complex.
Uzbekneftgaz reports that regular repair work on D-336-2 gas turbine engines and TKA-Ts-6.3, A / 0.17-0.9, M-1 compressors installed on the gas compressor units of the complex, have been performed by the engineering personnel of the station in accordance with the manufacturer's instructions.
“In the course of maintenance and repair work, the inside of the gas generators was washed with softened water using a special detergent,” Uzbekneftgaz said.
In addition, air, fuel and oil filters of gas turbine engines have been completely replaced. All main and auxiliary equipment of gas turbine engines and compressors have been fully tested. Also, in the process of repair, a number of technically complex calculations are performed, as well as commissioning work.
As a result, it was possible to ensure uninterrupted, stable operation of gas pumping units and prevent a decrease in natural gas production. A reserve unit is also envisaged for performing routine maintenance and putting it into operation as soon as possible in order to prevent gas leakage during an emergency stop of the gas drive unit.
Compressor stations at collection point No. 2, 3, 6 of the Kukdumalok complex are located in the Mirishkor district of the Kashkadarya region and have four gas pumping units. The stations have the capacity to pump 1.4 million cubic meters of natural gas per year. In 2009–2011, gas turbine engines of the D-336-2 brand produced by the Ukrainian state plant Motor Sich JSC were installed and put into operation at the gas-pumping units of these stations.
