How Propeller Pitch and Diameter Affect Ship Performance
Propeller pitch and diameter are critical factors influencing a ship’s speed, fuel efficiency, and maneuverability. A higher pitch increases speed potential but demands more engine power, while a lower pitch enhances acceleration and control. Similarly, a larger diameter generates more thrust and improves efficiency at lower RPMs, whereas a smaller diameter suits high-speed vessels but may increase cavitation. Selecting the right propeller configuration ensures optimal performance, balancing ...

Fatigue Crack Detection in Marine Propellers
Fatigue cracks in marine propellers develop due to cyclic hydrodynamic stresses, cavitation, corrosion, and operational conditions. Detecting these cracks early is crucial for maintaining efficiency, preventing failures, and reducing repair costs. Common non-destructive testing (NDT) methods include visual inspection, dye penetrant testing (DPT), magnetic particle inspection (MPI), ultrasonic testing (UT), eddy current testing (ECT), and radiographic X-ray inspection. Regular inspections, pro...
