Project: 1.96MW - 97 & 3.4MW-140 Platforms

• Acquire information for AEP (Annual Energy Production), aerodynamic requirements, number of blade sets to manufacture, timeline for customer fulfillment and structural capability of the blades to withstand the loads at windfarm sites.
• Work with Conceptual design team & Manufacturing team to check the structural ability of the blade as per requirements laid down in first cut structural analysis.
• Detail planning and execution from product structures side, by utilizing the framework from aerodynamic team and standard tools to demonstrate the blade good for prototype building, testing and finally acquiring certification.
• Work closely with plant for any materials and process deviations and impact on S&OP target of the Bangalore & Vadodara Plants.

Awards & Recognition :

• Impact Award: Based on Manufacturing plan utilization of procured materials with lower strength properties saved $30Mn worth raw material with a profit margin of $500k.
• Applause Award: Receiving certification for 1.96MW - 97 platform.
