The first non-oEM manufacturer in the world of manufacturing 8 rows of fixed and mobile hot turbine Kraft V.93

Eng. Manuchehr Shahmiri, TABA knowledge-based engineering and Service Company’s project manager, has announced manufacturing of hollow Shaft Shell, U-ring and hot spare parts of other fixed and mobile blades of Kraft Turbine V.93 of Lowshan Power Plant.

He noted that the implementation of this project in short time and with high quality components made a major achievement in the construction of hot turbine blades, and was carried out by continuous and precise effort of the engineering, quality control, planning and commercial colleagues and the guidance and support of the CEO and the members of the Board of Directors of TABA Knowledge-Based company and the effective supervision of Lowshan Power Generation Company and Lowshan Power Management Company.

 

The parts of this turbine were manufactured and supplied by Siemens, which, due to the lack of manufacturer's support in supplying the turbine parts, was commissioned to tender for the construction of these parts by the domestic companies, which TABA knowledge- based engineering company was announced as the winner. Hereby manufacturing of 1-4 rows of mobile blades, 1-4 rows of fixed turbine blades, middle hollow shaft case, U-ring, colors seal divider and other spare parts of the turbines were delivered to TABA.

Manufacturing of these parts began with reverse engineering by three-dimensional optics, modeling and providing drawings based on installation tolerances and casting simulation.

In the next phase of engineering, the quality control guidelines and acceptance criteria for precision casting of super-alloy under vacuum, forge, coating, sheet working, welding and dimensional control instructions were prepared by TABA engineering and R&D Unit.

The quality control team of this company continuously expressed its views during construction with the presence of qualified contractors, and finally, at the end of construction, the parts were delivered and approved according to the control guidelines.

He added that the project was completed within a short timeframe of about one year with the follow-up of the planning and commercial colleagues due to contractual Gantt charts with contractors.

The manager of this project added that supplying the strategic raw material mostly face boycotts, and exchange rate fluctuations, currency shortages in the country, and currency problems in the first two months of 2018 caused many unpredictable problems in the project, but with weekly and even daily follow-ups, we were able to deliver the parts at the time of the overhaul of the Lowshan power plant unit. Now that I’m having this interview, I proudly announce that the parts have been installed correctly and successfully in cooperation with the Lowshan power plant repairing team and have all the permissible installation tolerances. All of the strategic parts of the turbine have been manufactured by TABA Company.

He added that although the project was approved by the employer, the strategy of this company is moving towards greater satisfaction of the employers.

 

He continued, the construction of fixed and mobile 1-4 rows of the same turbine at Shiraz Power Plant was transferred to TABA Knowledge-based company in a bid in 2017 and now the company is in the process of finalizing parts and delivering them to the employer within next month.

We would like to thank the project stakeholders, especially the Thermal Power Generation Company, the Lowshan Power Generation Company, and the Lowshan Power Management Company and their cooperation during the project, and I hope that in the year of supporting Iranian production by maximum utilization of engineering power, Equipment and management of Iranian and native manufacturing processes, provide more services to our country's electricity industry.
