Integration of Electromagnetic Technologies Into Shipboard Applications

Technical progress has led to the ability to manipulate energy transfer such that prior ship applications using mechanical or hydraulic energy conversion can often be replaced by more reliable and efficient electromechanical methods. This paper reviews recent developments in electric propulsion motors and integrated power systems for ships. Examples are given for cruise ships, cargo ships and special applications like ice breakers and oceanographic exploration. Emerging technologies are described, for example, superconducting propulsion motors, superconducting bus, fuel cells, and autonomous unmanned vehicles for oceanographic mapping and studies
