Shaft alignment is a crucial process in shipbuilding and marine maintenance where specialists ensure that a ship's propeller shaft is perfectly lined up with the engine. Think of it like making sure wheels on a car are properly aligned, but for ships. When alignment is off, it can cause serious damage to the ship's engine, increase fuel consumption, and lead to expensive repairs. This skill is essential in shipyards, marine repair facilities, and anywhere large marine equipment needs installation or maintenance.
