Commercial marine motors in general are high-grade motors treated for corrosion resistance and designed for use on shipboard applications. These motors meet the regulatory requirements governed by three major specifications: the American Bureau of Shipping (ABS) Rules for Building and Classing Marine Vessels1, the United States Coast Guard (USCG) Electrical Engineering Regulations2 and the Institute of Electrical and Electronics Engineers (IEEE) Standard 45, Recommended Practice for Electric Installations on Shipboard3. Marine motors are also used for other-than-shipboard service in functions on offshore drilling rigs, shipyard applications and port equipment. Marine motors are usually mounted to steel structures, which are subject to vibration and shock or pitch and roll movement, and typical marine application settings are very humid and salt-laden harsh environments. Therefore, the environments in which shipboard motors operate and the functions they perform require unique design and construction considerations above those of standard industrial motors.
