Design Certification of Equipment

Design certification is becoming more and more popular and in the case of some mining clients is now a requirement for all new equipment. Design certification can be achieved for both new and used equipment, provided certain information is known:

1) For new equipment the following is required:

  • A drawing that fix the design (dimensions, materials and welding)
  • Engineering calculations (require loads and load combinations)

2) For existing equipment

  • A drawing¬†that fix the design (dimensions, materials and welding). The equipment would therefore need to be measured up (in some cases dismantled)
  • Engineering calculations (require loads and load combinations)
  • Actual load test to confirm the design calculations and construction.

We can help with all of the above. By developing a 3D model of your equipment and applying the loads, we can produce a stress plot that can be used to prove the design or even to increase the reliability of the design. It is fast, cost effective and saves a lot of time and money associated with breakdowns – not to mention the safety risks associated with failures.

In some cases we are asked to give our opinion if certain maintenance activities would be safe. One such  assignment was to check if a corroded tailing pipe could be lifted while in operation. Our analysis showed this to be a high risk activity and we advised our client against this Рshowing areas of concern as well as the behaviour of the model under certain load cases. With our model we were able to predict load versus deflection curves, as well as the required crane tonnage.

Although our analysis indicated that the lift should not take place, our client still received the benefit of avoiding a large clean-up bill and other associated incidents. Sometimes it really pays to check out the engineering aspects of a job before it is attempted.
