Marine Engine and Generator Alignment for Superyachts

When alignment should be reviewed

Alignment can become relevant after machinery has been moved, disconnected or reinstalled, or when the engineering team identifies unusual vibration or concerns about an installation. The appropriate checks depend on the arrangement: a generator set, engine-to-gearbox connection and propulsion drivetrain do not share one universal procedure.

We review the installation, mounts, coupling arrangement, access and available manufacturer information before confirming the scope.

Measurement, adjustment and installation conditions

An alignment programme should specify the reference points, equipment condition, measurement method and applicable acceptance criteria. Vessel loading, temperature and afloat or ashore conditions may affect the interpretation of results and need to be considered where relevant.

Mechanical adjustments and follow-up checks are planned around the installation and any related works. We do not apply a generic tolerance to every yacht or engine configuration.

Records for the Chief Engineer

Useful handover documentation explains what was measured, what was adjusted, which reference criteria were used and whether further checks are recommended. This is particularly valuable when the work forms part of a larger engine overhaul or generator service.
