Precision Propeller Repair and Maintenance

At AstroTech Marine, we understand that a propeller’s condition is fundamental to a vessel’s efficiency, performance, and fuel economy. Even minor damage—such as bends, cracks, or erosion—can significantly impact vibration, speed, and ultimately, your operational costs.

Our team of specialised marine engineers and certified welders provides complete repair, modification, and maintenance solutions for all types of propellers, including Fixed Pitch Propellers (FPP), Controllable Pitch Propellers (CPP), and highly specialised high-skew units. We meticulously execute every repair, utilising advanced techniques like hydrodynamic analysis, cold-straightening, and class-approved welding procedures to restore the propeller to its original design specification.

AstroTech Marine ensures your propulsion system delivers maximum thrust and efficiency by offering services ranging from blade straightening, pitch correction, and tip repair to precise dynamic balancing and anti-corrosion coating application. We are committed to delivering on-time, class-compliant, and performance-driven solutions that keep your vessel operating smoothly and confidently across UAE and international waters.
