Information technologies for smart ship propulsion systems

Electrical propulsion concept is not new. It has already been tested in late 19th century. There were only few civil Trans-Atlantic ships in operation by early 1920s with implemented electrical shaft concept. On the other hand, by that time it was widely accepted onboard the submarines and war ships (Tennessee class battleships). The advantages of that new technology, like easy reversing, silent work and great maneuverability were ideal for navy ships. There was a continuous development of the electrical propulsion technology since then, but mostly focused to the military usage. It has been used occasionally onboard commercial vessels, but more as an exception than the rule. The 80s and early 90s of the twentieth century was the time when electrical propulsion finally found its way to the commercial market as well. At that time, the Integrated Electrical Propulsion (IEP) concept was born and become the foundation for next generations of navy and commercial ship concepts like All Electrical Ship (AES) and SMART SHIP. The purpose of this article is to provide inside to the information and electronics technologies behind smart ship propulsion systems, and their future development.
