Trouble Shooting Services

Problems with machinery and structures often involve complex issues with many possible root causes.

In some cases these causes and problems influence and reinforce each other so a methodical troubleshooting approach is needed to sift through these challenges and solve the underlying problem.



For more than 40 years, AVT Reliability BV (formerly Van Geffen Reliability) has been recognised worldwide for its independent and reliable troubleshooting expertise. Leading production operators, OEMs, service providers, shipyards, and insurers rely on AVT Reliability to identify the root causes of problems affecting rotating and static equipment.

Within our field of work, most issues can be traced to vibration behaviour, elevated bearing, shaft or coupling temperatures, component failures, cracks in structures or foundations, excessive noise, installation-related problems such as pipe strain or foundation flatness, or simply deviating asset performance.

Our approach combines advanced measurement techniques for rotating equipment such as compressors, pumps, fans, and engines with dynamic analysis of static assets including foundations, structures, and piping systems.

Wherever possible, we identify the root cause and implement immediate corrective actions on site. For more complex issues, advanced simulation and modelling tools are applied to accurately reproduce the problem and evaluate effective solutions.

This structured, evidence-based approach consistently delivers a fast and cost-effective resolution, ensuring problems are solved first time right and avoiding expensive trial-and-error methods.

AVT Reliability has over 40 years of worldwide experience in troubleshooting complex problems on rotating and static equipment. Operators, OEMs, shipyards, and insurers rely on us to identify root causes and restore reliable operation.

By combining advanced measurements with simulation and modelling, we resolve issues quickly, accurately, and cost-effectively, avoiding trial-and-error solutions.



Problems affecting machinery and structures are often complex, with multiple potential root causes that may interact or reinforce one another. A structured and methodical approach is therefore essential to isolate the true cause and resolve the issue effectively.

In most cases, a field visit is required to assess the situation, perform targeted measurements, analyse the data, and develop practical recommendations. For more complex issues, computer models and simulations are applied to evaluate possible solutions and determine the optimal corrective action.

Field measurement data is used to validate these models, ensuring that conclusions and recommendations are firmly grounded in real operating conditions.

Prior to each project, a multidisciplinary team is assembled with the appropriate technical expertise and asset- and industry-specific knowledge. This ensures that each investigation is approached with the right combination of experience, analytical capability, and practical insight.

Machinery and structural problems often involve multiple interacting root causes. A structured and methodical approach is essential to identify and resolve the underlying issue.

Field measurements, supported by simulation and modelling where required, allow us to validate findings and define effective, practical solutions. Each project is supported by a multidisciplinary team with the right technical and industry expertise.



Troubleshooting process and analysis
Trouble Shooting Process

Our engineers apply a structured troubleshooting methodology, combining field measurements,
inspections, and advanced simulations to systematically identify the root cause of the problem.
