Optical Alignment in Vessel Drivelines ⚓

Precise driveline alignment is essential for efficient, reliable, and vibration-free vessel operation. Even minimal angular or parallel misalignment between the engine, gearbox, and shaft line can produce high vibration, premature bearing wear, and reduced propulsion efficiency.

At G&M Mechanical Engineering LLC, we specialize in optical and laser alignment for marine propulsion systems. Using precision optical instruments and laser-based systems, our technicians align every component along the theoretical centerline — ensuring that the engine output flange, reduction gear, shaft bearings, and propeller hub operate in perfect harmony.

Unlike traditional straightedge or feeler-gauge methods, optical alignment provides micron-level accuracy, which is critical after major overhauls, bearing replacements, or hull modifications. Our alignment procedures follow ABS, ISO, and manufacturer specifications, guaranteeing each shaft line is correctly positioned to distribute load evenly across bearings and minimize torsional stress.

The benefits are measurable: reduced vibration, smoother operation, improved fuel efficiency, and extended component life. Optical alignment also lowers the risk of seal leaks and coupling wear, both of which are common causes of propulsion failures at sea.

With experience in shipyards, yacht refits, and government vessels, G&M Mechanical Engineering delivers alignment solutions trusted by marine professionals. We ensure your propulsion system runs precisely as designed — quiet, efficient, and vibration-free.
