FAQs

1. What does Borescope & Drivetrain Assessment include?
This service assesses the condition of critical drivetrain components such as gearboxes and main bearings using borescope inspections, helping identify wear, damage, and emerging failures before they impact performance.

2. Why are gearbox and main bearing inspections important?
Gearboxes and main bearings are high-value, failure-prone components. Early condition assessment helps prevent catastrophic breakdowns, reduce repair costs, extend component life, and avoid unplanned downtime.

3. How are borescope inspections carried out safely?
We follow approved borescope plans and safety method statements to ensure inspections are performed safely, efficiently, and in line with site, OEM, and regulatory requirements.

4. What evidence and reporting do you provide after inspections?
We deliver detailed inspection reports including photo and video evidence, defect identification, severity grading, and clear findings that support maintenance and investment decisions.

5. What recommendations are included in drivetrain assessment reports?
Our reports provide actionable repair, replacement, or monitoring recommendations based on component condition, risk level, and operational impact, enabling informed asset management planning.

6. How does this service support maintenance and lifecycle decisions?
By understanding drivetrain health, asset owners can prioritize maintenance, plan major repairs, support warranty or insurance claims, and make data-driven decisions on life extension or component replacement.
