In an intensive, round-the-clock process, the Iranian Gas Engineering and Development Company succeeded in successfully completing the final tie-in operation of the Nourabad gas pressure boosting facility to the tenth national gas pipeline within 6 days.

According to Shana, citing the Iranian 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 connection operation to be the result of the comprehensive cooperation of the National Gas Dispatching Management and Region 5 of the gas transmission operations and a fundamental step in the process of launching 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-launch operations are completed, we can put it into service.”

According to him, the Noorabad gas pressure boosting facility is under construction in Fars Province on the 10th National Gas Pipeline. Given the strategic nature of this line, which is one of the country’s main gas transmission lines, it will have a significant impact on the national gas network. With its launch, 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: “All of this advanced equipment is manufactured by Mapnast Company and is currently being installed. When the facility is commissioned, the inlet and outlet valves are opened so that the gas passes through the compressors instead of passing through the line, and the inlet pressure increases from 850 to 1200 psi and returns to the line.”

The sensitivity of performing the final connection operation of the Noorabad facility

Explaining the urgency and importance of the final connection operation of the Noorabad facility, Sarani explained: Since this facility is located at the beginning of the tenth national gas pipeline, performing the final connection operation there is particularly sensitive. Accordingly, this process was carried out quickly and in a short period of time so that consumers of this strategic line do not face any problems.

She continued: “No connections had been foreseen or installed in the past to connect the Noorabad gas pressure boosting facility to the 10th National Pipeline, so it was necessary to perform the required cutting work on the 10th National Gas Pipeline to connect 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. He said: “The 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 functioning 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’s inspection team and then sent to the project site.”

Referring to the management and foresight of those in charge of this matter, she said: Carrying out such an operation in the summer, when the network faces fewer restrictions than peak consumption in the winter, will help 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 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 the Design and Inspection Company as the contractor and the precision and cooperation of the Energy Process Engineers Company as the project consultant resulted in this very heavy activity being completed in a limited time.
