| Basic Facts | |
|---|---|
| Client: | Worldwide supplier of choice for utility customers |
| Project Location: | Charleston, South Carolina, USA |
| The challenge: | Performing strain gage testing and load monitoring on the structure where direct measurement was not desirable to achieve accurate results. |
| Main service: | Calibrated strain gauge measurements. |
| Benefits: | Assurance that the dynamic plus static loads did not exceed the designated thresholds for the generator, cradle and dock, thereby ensuring that the loading procedure does not put undue stresses on the dock and structures involved. |
Solution and Results
TÜV Rheinland Industrial Services has had a long-standing relationship with this worldwide supplier, and when the test experts received the request, they brought on board their colleagues from TÜV Rheinland Mobility. Mobility uses strain gage testing extensively in the rail industry to evaluate the magnitude and frequency of stresses on rail vehicles. TÜV Rheinland has been performing strain gage testing since 1987 across all industries: from rail tracks and vehicles to bridges and buildings.
At the dock, TÜV Rheinland engineers placed custom designed pre-calibrated gages at certain points of the cradle and measured the static and dynamic loads while a loading procedure took place to ensure safety and integrity of the cradle and the dock. The experts encountered a few challenges onsite: Because they could not put strain gages on the cradle directly so that not to affect its surface, they designed collars outfitted with the pre-calibrated strain gauges that were positioned between long bolts and the dock cradle and measured the forces indirectly.
Site-specific challenges often require a test engineer to think outside the box: from and adequately address the clients’ request. Powering the equipment when there are no power outlets nearby to understanding how to compensate for thermal stresses if a structure itself deforms during testing. This is where many years of performing tests on a variety of structures paid off: The TÜV Rheinland team could account for the test conditions at the dock without impacting the accuracy of measurements.
