Ferry Propulsion Shaft Alignment — 45 m Vessel
- Client
- MV Coastal Runner (sample)
- Year
- 2024
- Scope
- Full shaft line, both engines
- Deliverable
- Alignment report + correction moves
Problem
Persistent stern tube bearing wear on a 45 m passenger ferry, with an eight-day drydock window booked at a BC yard — no time for trial-and-error alignment.
Method
Laser tracker survey of the complete shaft line to ±0.05 mm, bearing reaction analysis by P.Eng, and correction moves computed for each chock before machining.
Result
Chocks machined once, alignment verified before flood-up, vessel sailed on schedule. Bearing temperatures normal through the following season.
