Introduction to Maintenance
Whether a ship at sea, a car in your driveway or an 800 MW electrical generator at a power plant, all equipment is subjected to wear. Sometimes the wear is in the form of corrosion from exposure to chemicals or harsh atmospheric conditions. Sometimes it is due to friction or heat. Continued wear eventually results in failure of the equipment.
Equipment is designed to perform a specific function over a defined time period. Excessive wear reduces the lifespan causing early failures.
Whatever the cause, it is the inspection, repair, and replacement of components, known as maintenance that keeps the equipment running.
