US Based Renewable Energy Product Supplier Cut Its Stress Analysis Cost to 50% by Partnering With Back Office Pro

The Business Need

This client needed high quality engineering support services in the field of 3D modelling, finite element analysis, detailing and drafting. The specific need of the client was very technical - it needed us to provide fabrication drawings, perform stress analysis exclusively for a prototype hub crane-lifting tool, something that is extensively used in the renewable energy industry. They also needed the partner to calculate the equipment's working load limit rating so as to know exactly how much load could be exerted on it.

The Client

The client is an American Renewable Energy Products' Supplier that mainly deals in the research, development and maintenance of wind and solar energy tools.

The Challenges

As the project progressed, these were the challenges we had to face -

Once we had the proper team to get the job done, cracking the brief was pretty easy. This is how we did it:

  • The client issued a limit of 83.3 N/mm2 of maximum stress on the lifting tool
  • We had to turn rough concept sketches into 2D manufacturing diagrams, 3D models and use them to compile a Stress Analysis Report
  • Ensuring that engineers with proven skills on SolidWorks 2012 and ANSYS were used
  • ANSYS was used for conducting stress analysis as per the client's demand
  • Compliance with the highest quality norms

The Back Office Pro Solution

After adequately analysing the client requirements, these are the solutions we worked towards successfully -

  • Used SolidWorks 2012 to develop 3D models and manufacturing drawings which included 3D models of the hub-crane and 2D fabrication diagrams of the same
  • Bagging the client's approval before proceeding with the stress analysis
  • Using an efficient team of engineers trained in ANSYS to conduct the stress analysis
  • We redesigned the tool model when we found that the stress analysis revealed deviations from the desired benchmark
  • Added proper reinforcement plates to the area around the wielded joints before repeating the stress analysis
  • Achieving success by not crossing the stress requirement level of 83.3 N/mm2



Owing to our technical expertise and competitive rates, the client ended up saving its operational costs by 50%. If you think your business could make use of our expert staff as well, feel free to get in touch with us at your earliest convenience.
