Case Study
Fatigue-Life Assessment on a Seismic Source Vehicle
OVERVIEW Inova Geophysical manufactures the UNIVIBTM (PLS-326) small vibrator vehicle used for vibroseismic operations during oil and gas exploration. ATA provided operational test services for three variations of the UNIVIB vehicle. Over the course of multiple days, the vehicles were driven over a rigorous course to simulate various operational conditions while a robust SoMat data acquisition system was employed to acquire critical strain and acceleration data. Data was reviewed in near real time to quantify the severity of the events and make qualitative assessments on the integrity of the various vehicle configurations. ATA’s support proved valuable in validating the robustness of the vehicle design and ensuring that Inova’s customers receive the highest-quality vehicle products
