When a propeller shaft suffers damage, it may seem like an irreparable problem. However, MarineShaft, a leading provider of shaft repair services, has the expertise and equipment to fix even the most severely damaged shafts.
Repairing Damaged Propeller Shafts
According to MarineShaft, they can repair any type of damage on shafts, no matter the cause. “No matter what caused the damage, we have the knowhow and workshop equipment to fix your shaft problem,” the company states. This includes damages that occur during shaft withdrawal, coupling removal, or other shaft line arrangement failures.
MarineShaft’s approach involves a thorough inspection of the shaft in collaboration with the relevant classification society, followed by a repair process that is fully approved by these authorities. The company’s specialized hydraulic presses, capable of applying up to 6,000 tons of force, can straighten shafts ranging from 20mm to over 1,500mm in diameter.
Advantages of Shaft Straightening
Straightening damaged shafts offers several advantages over manufacturing new ones. It is a faster process, with many jobs completed within 24-48 hours of the shaft arriving at the workshop. It is also a more economical solution, as MarineShaft can straighten shafts from all over the world, regardless of where the damage occurred.
Additionally, the straightened shafts can often achieve a better straightness than new shafts, with MarineShaft regularly achieving a straightness of 0.05mm or better, even on very large shafts.
