One-Day Seminar Discusses Energy-Saving Potential Of A-C Variable Speed Drives For Shipboard Application

A seminar discussing the energy-saving potential of A-C variable speed electric drives for shipboard pumps, fans, hoists and winches was recently held in New York City by Reliance Electric Company.

The one-day seminar provided information about A-C variable speed drive and energy efficient motor basics, along with application ideas and comparisons to traditional shipboard flow/ volume control of fluids, air and steam.

Application of these drives and motors aboard a steam turbine vessel allows forced draft fan speed modulation rather than traditional inlet guide vanes and dampers to control excess air and provide faster responses to fuel quality.

This allows a better combustion ratio, providing more nautical miles per ton of oil. With fuel costs accounting for no less than 50 percent of the total cost of operating a merchant vessel, the saving potential can be significant.

To provide potential users with cost-saving information, Reliance Electric provides a free flow control cost analysis utilizing a computer program to determine whether an A-C adjustable speed drive can be more beneficially applied over another flow control method. The analysis can be performed by any Reliance Electric sales office nationwide.
