AHV-IV™ Vibrators
PROVEN AND TRUSTED
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
Did you know
Accurately charged accumulators dampen mechanical noise at the actuator so accelerometer measurements of ground force are more accurate.
More than 600 AHV-IV vibrators have been sold directly for use the extreme heat of desert environments
AHV-IVs can be customized in a variety of ways to provide the ultimate operating experience

Geophysical Benefits
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.

Operational Benefits
Anyone who’s spent time maintaining a vib fleet knows how mechanical failures and downtime can delay a seismic acquisition program - delays that are costly to both the geophysical contractor and the E&P operator. The ability to easily diagnose and fix problems in the field is essential, but more importantly, reliability and uptime are the primary reasons why the AHV-IV class of vibrators is still #1 in the industry.
With more than 1800 in operation around the world and a rich history that dates back to 1970 with the introduction of the very first AHV vibrator (under Litton Resources Services aka LRS), the AHV-IV product line is still known for its dependability and durability today.
Highlights
iX
All INOVA systems contain a robust software called iX that consolidates source control and spread management into one simplified view for the Party Chief. Managing and visualizing source operations on a single system ensures higher quality imaging through better QC so you never miss a sweep.

Auto-Greasing System
A built-in system that auto-lubricates contact points which reduces wear and tear on high friction parts such as pins and guide columns.
Accumulator Charging Manifold Kit
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.
Bypass Filtration Kit
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.
Winter Housing
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.
Safety Kits
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.
"Dawson owns the largest fleet of INOVA AHV-IV series vibrators in North America and we have been very pleased with the performance over many years of operation. We have a team of in-house vibrator expertise that performs regular service and maintenance to ensure these vehicles function at their optimal level. INOVA vibrators have proven to be very reliable, minimizing our total cost of ownership."
