INOVA - Model AHV-IV™ -Vibrators
INOVA proudly represents the durable, low-maintenance AHV-IV family of vibrators with the latest advances in source technology implemented in the industry standard Articulated Hydrostatic Vehicle (AHV) design. A variety of configurations and a comprehensive selection of customizable options are avaiable on our AHV-IV product line to accommodate variations in terrain, environment, or imaging requirements. INOVA offers two options to meet imaging and operational requirements in the form of different actuators - the PLS-364 Commander and the PLS-380 Renegade. These are available with customizable features, such as a winter-package for arctic environments and standard or heavy-duty tracks for loose impediment and icy conditions
Ensuring P-wave propagation and high-force energy penetration in a variety of terrains is our first priority when implementing new vib technology or design changes to our AHV-IV Commander and Renegade vibrators.
If your imaging goal is waveform inversion model building (Baeten, 2013) or structural analysis that requires wavelet sharpness (Denis, 2013), the AHV-IV is the best broadband vibrator for the survey.
Highlights
- Widest bandwidth for large class vibrators: <1 to 250 Hz
- Highest peak force-energy penetration
- Lowest full-drive frequency (5.18 Hz)
- Excellent source signature consistency across full bandwidth in any terrain
- Baseplate is 2.5x stiffer than conventional baseplates
A built-in system that auto-lubricates contact points which reduces wear and tear on high friction parts such as pins and guide columns.
Within the AHV-IV there are four accumulators that require nitrogen charging. This kit simplifies the process and helps a vib tech manage the appropriate levels of pressure to charge the nitrogen to help reduce noise and provide a more accurate measure of force.
In high-productivity 24/7 operations, it can be difficult to schedule routine oil changes without breaking stride. We’ve created a hydraulic oil filtration kit that helps remove contaminants and prolongs the life of the oil.
For operations in Arctic climates where freezing temperatures make vibrator maintenance nearly impossible, we’ve created a fully enclosed environment complete with cameras and a lighting system to provide shelter for the technician and to keep the vib components protected.
Due to their size, rear visibility and emergency braking in a vib can be incredibly difficult leading to costly errors. Additional features such as backup cameras or an external emergency stop control can be installed to help prevent HSE-related incidents.
