Propeller Shaft Alignment for Crew Boat

Challenges

• Severe vibration at mid-RPM

• Misalignment caused by bearing wear

• Crew reported increased fuel usage

Scope of Work

• Laser shaft alignment

• Coupling inspection

• Stern tube & bearing verification

• Propeller condition assessment

• Sea trial observation

Process Executed

Using precision laser alignment tools, the shaft, coupling, and bearings were re-aligned. Lubrication and minor bearing adjustments were also carried out.

Results / Outcome

• Vibration fully eliminated

• Fuel consumption improved by 8–10%

• Smooth propulsion and increased comfort
