A customer vessel was facing significant vibration issues from the main engine, especially at 92 RPM.
Background
Horizontal vibrations in 6th order exceeded 7 mm/s RMS, pushing both equipment and onboard conditions beyond acceptable thresholds.
High vibration levels like these increase fatigue on structural components and jeopardise the well-being of the crew, especially during longer voyages.
The Customers Challenge
The customer needed a solution that could significantly reduce horizontal engine vibrations without prolonging docking time or compromising engine performance
Solution: Installation of G&O Compensator
G&O Compensators installed one of its high-efficiency horizontal vibration compensators, designed specifically to absorb and counteract complex multi-order vibrations from two-stroke engines.
The installation included:
- Advanced ship vibration analysis before installation
- Implementation of a compensator tuned to the vessel’s operational profile
- On-site fine-tuning and verification by a G&O service engineer
Result: 89.08% Vibration Reduction
After installation, vibration levels fell from over 7 mm/s RMS to well below 1 mm/s RMS in 6th order horizontal motion—a reduction of 89.08%.
This was not just visible in the data, but also in real-life onboard conditions.
“The ship became so calm after the installation that our technician could place a 20 DKK coin on its edge in front of the compensator—and it stayed upright.”
– Morten Kjæmpe, Head of Service & Technical Support, G&O Compensators
Impact
- Major reduction in engine vibration
- Notable reduction in hull stress
- Significant reduction on stress in electrical equipment
- Improved operational stability
- Enhanced onboard comfort for crew
