Torsional Dampers – Safeguarding Engine Performance and Longevity

At AstroTech Marine, we understand that controlling torsional vibration is critical to the health and reliability of any marine propulsion system. Excessive vibration can lead to crankshaft fatigue, bearing wear, and severe damage to key drivetrain components if not properly managed.

Our OEM-trained propulsion engineers specialize in the inspection, overhaul, and replacement of torsional vibration dampers for main engines, auxiliary units, and propulsion lines. Using advanced diagnostic and balancing tools, we restore damping efficiency to protect your machinery and maintain smooth power delivery.

Whether viscous, elastomeric, or pendulum-type, every damper is serviced with precision to meet Class and OEM standards, ensuring vibration-free operation, reduced mechanical stress, and extended engine life. AstroTech Marine delivers performance-driven damper solutions that keep your vessel operating safely and efficiently across UAE and international waters.

Protecting Your Propulsion System from Harmful Vibrations

At AstroTech Marine Services, we understand that torsional vibration can be one of the most destructive forces within a propulsion system. A properly maintained torsional vibration damper (TVD) is vital to ensuring smooth power transmission, protecting crankshafts, couplings, and gearboxes from fatigue and premature failure.

Our team of OEM-trained propulsion specialists provides complete inspection, testing, repair, and overhaul services for all types of marine dampers, helping ship operators maintain optimal engine performance and reliability under all operating conditions.
