Stress Engineering has provided measurement services for clients on-site since our beginning over 30 years ago. In the field, we measure and solve real-world problems on operating structures and equipment. This also includes performing measurement services in other test facilities, so the description "Field Testing" is a broad term for measurement outside of Stress Engineering test labs.
We will mobilize a team of engineers and technicians with sensors and data-acquisition equipment to other locations, anywhere locally or around the world. Our teams are comprised of engineers skilled in numerous disciplines, including mechanical, civil, electrical, and metallurgical engineering, working with our experienced technicians.
Types of Measurement
We routinely use measurement sensors for:
Strain and stress
Problem solving is usually the motivating theme for these applications, in contrast to performance verification of a new design. In other words, if something does not work correctly or is failing too often. Perhaps service loads are exceeding the design assumptions, or the process needs adjustment to assure a long life. In fitness-for-service applications, measurements will determine if the aged equipment can continue to operate safely and conservatively.
Measurement can be considered as short-term (as a single day, for example) or long-term with with many months of data recording. A short-term test could be a proof load test at a fabricator, while a long-term test would include structural monitoring during startup, upsets, and shutdowns in process equipment.
The Stress Engineering staff will discuss the application and objectives with the client, and if necessary, recommend a sensor deployment strategy to characterize the nature of the structural response. This often requires close coordination with the client to install the sensors during an outage or prior to a startup.
Safety is a paramount concern for Stress Engineering, with both general and site-specific requirements to be met. Many Stress engineers and technicians maintain annual Safety Certification through the local Safety Council. Not only are personnel safety issues recognized, measurements are also used to protect equipment from damaging overloads.
Field testing can be applied and utilized by a number of diverse industries, such as:
Commercial test labs
Pulp and Paper Mills
Pressure vessel fabricators
Forge and machine shops
Offshore platform facilities
Ships and barges
Bridges and civil structures
Crane and mast fabricators
Acoustic Emission | Coke Drums | Failure Analysis
Field Measurements | Life Assessment | Residual Stress
