MAPNA Marks Gas Turbine Maintenance Milestone at Hengam Power Plant

The MAPNA Group has marked a significant milestone by completing the first Hot Gas Path Inspection (HGPI) on a Class F gas turbine at the Hengam power plant after 25,000 hours of operation. 

This achievement was realized through the combined efforts of MAPNA’s Power Plant Services, MAPNA Operation and Maintenance, MAPNA Turbine Engineering and Manufacturing Company (TUGA), and MAPNA Generator Engineering and Manufacturing Company (PARS).

The maintenance operation concluded on April 22, 2024, with the turbine being synchronized with the national electricity grid shortly thereafter. 

This success reflects the strategic and operational achievements under the 12-year Long-Term Service Agreement (LTSA) for Class F power plants managed by the Thermal Power Plants Holding Company.

This milestone is pivotal in expanding MAPNA’s services in gas turbine maintenance and repair for Class F turbines, notably accomplished independently of foreign manufacturers. 

The project has led to significant advancements in the parts supply chain, specialized tool manufacturing, engineering documentation, and the execution of planned repairs that meet acceptance criteria during turbine disassembly and assembly operations.

These developments not only add value but also strengthen MAPNA Group’s competitive position in the gas turbine service industry. Hengam F-Class Power Plant is located 20 km from Bandar Abbas on the road to Shahid Raja’ei Port, adjacent to Bandar Abbas Steam Power Plant. The power plant comprises two gas-fired units equipped with MAPNA’s F-Class turbines with a capacity of 307 MW at ISO conditions, two gas recovery boilers, a 292-MW steam unit, and an air-cooling system.
