MAPNA Turbine Blade Engineering and Manufacturing Company, PARTO, was established in 2000 to add to what MAPNA Group stands for: excellence and it tried to do that in every aspect by bringing creative people together, utilizing state-of-the-art technology and developing turbine blade manufacturing knowledge.
At the first step PARTO acquired Siemens license for production of V94.2 (160MW) gas turbine blades and vanes. In order to increase power output and efficiency of MGT70 during recent years, MAPNA group initiated three large projects, namely MAP2+, MAP2A and MAP2B which led to increase the output and efficiency of this turbine to 181MW.
Drawing on an engineering and production system based on the OEM methodology and through smart utilization of lessons learnt from know-how transfer, several other types of gas turbine blades and vanes(such as GE-F9,H25, F6, GT13-E2)  were reverse-engineered at the next step, and delivered to the power generation market. To date, more than 130 thousand products of PARTO have been put into operation, delivering more than 15,000,000 EOH (Equivalent Operating Hours) without failure.
