A leading global heavy-duty gas turbine manufacturer required a complete acoustic enclosure solution for a 385MW M701F4 gas turbine power plant project in Morocco.
The M701F4 F-class heavy-duty gas turbine is widely applied in large-scale combined cycle power plants worldwide. The project required extremely high standards for structural strength, welding accuracy, acoustic performance, corrosion resistance, and dimensional control.
CLET provided an integrated design and manufacturing solution for the complete acoustic enclosure package, including gas turbine turning gear acoustic enclosure and auxiliary equipment acoustic enclosures.
This project was a direct overseas supply order from a global gas turbine OEM, representing an important milestone in CLET’s cooperation with international heavy-duty gas turbine manufacturers.
