Hirgan Energy Engineering Company, in an intensive, round-the-clock process, successfully completed the final tie-in operation of the Noorabad gas pressure boosting facility to the 10th national gas pipeline within 6 days.
According to Shana, citing Iran Gas Engineering and Development Company, Sam Sarani, head of the construction and installation project of the gas pressure boosting facility, considered the successful completion of the final tie-in operation to be the result of the comprehensive cooperation of the EPC contractor (Hirgan Energy Engineering Company), the National Gas Dispatching Management, and Region 5 of the gas transmission operations, and a fundamental step in the process of commissioning the Noorabad facility, and stated: Now the gas has reached the inlet and outlet valves of the Noorabad facility, and as soon as the pre-commissioning operations are completed, we can put it into service.
According to him, the Noorabad gas pressure boosting facility is being built in Fars province on the 10th national gas pipeline. Given the strategic nature of this line, which is one of the main gas transmission lines in the country, it will have a significant impact on the national gas network. With its commissioning, 15 to 16 million cubic meters per day will be added to the initial capacity of the line.
The head of the construction and installation project of the gas pressure boosting facility, pointing out that this facility has a 3+1 arrangement and includes three turbines in service and one spare turbine, stated: Advanced gas compressors manufactured by Mapnast Company are currently being installed, and during the commissioning of the facility, the inlet and outlet valves will be opened so that the gas passes through the compressors instead of passing through the line and the inlet pressure will increase from 850 to 1200 psi and return to the line.
The sensitivity of the final connection operation of the Noorabad facility
Sarani explained the urgency and importance of the final connection operation of the Noorabad facility: Since this facility is located at the beginning of the 10th National Gas Pipeline, the final connection operation is particularly sensitive. Accordingly, this process was carried out quickly and in a short period of time so that the consumers of this strategic line do not face any problems.
He continued: No connections had been foreseen and installed in the past to connect the Noorabad gas pressure boosting facility to the 10th National Gas Pipeline, so it was necessary to perform the required cutting work on the 10th National Gas Pipeline to connect it to the facility.
The head of the construction and installation of the gas pressure boosting facility project stated that the 56-inch and 48-inch inlet and outlet valves of the facility, the installation of the 56-inch valve on the 10th national gas pipeline, the valves and piping of the 20-inch bypass line, and the hydrotesting of all lines are among the most important activities of the final connection, and said: Severe time constraints and the location and placement of the valves were the characteristics of this operation, and a 160-ton crane was used to install the 56-inch valve.
Sarani continued: In order to ensure the correct operation of the 20-inch, 48-inch, and 56-inch valves, all of these items were sent to the Shahid Kolahduz factory for testing in the presence of the Gas Engineering and Development Company inspection and then sent to the project site.
Referring to the management and foresight of the custodians of this issue, he said: Carrying out such an operation in the summer season, when the network is facing a less restrictive situation than the peak consumption in winter, helps to achieve the goal of launching the facility before the cold season.
In the end, he thanked the coordination and cohesion of the executive elements, including Hirgan Energy Partnership – Design and Inspection, the project management group, the officials of the gas pressure boosting facility project, and the operating group of Region 5, who were responsible for cutting the 10th national line, and said: “The round-the-clock efforts of Hirgan Energy Partnership – Design and Inspection as the contractor and the precision and cooperation of Farayand Sazan Energy Company as the project consultant made this very heavy activity bear fruit in a limited time.”
