The recommendations for electrical power generation@ distribution@ and electric propulsion system design for use on shipboard are established by this document. These recommendations reflect the present-day technologies@ engineering methods@ and engineering practices. This document is intended to be used in conjunction with the IEEE Std 45 series. Purpose The main purpose of this recommended practice is to provide a consensus of recommended design practices in the unique field of marine electrical engineering as applied specifically to ships@ shipboard systems@ and equipment.
