An assessment of electric motors from the point of marine propulsion systems

Abstract

The global environmental concern and the limited resources of fossil fuels warrant the use of alternative and renewable energy sources. The International Maritime Organisation aims to increase energy efficiency and reduce emissions from marine vessels. In this context, in addition to the conventional propulsion system, the application of hybrid propulsion system (HPS) and diesel-electric propulsion system (DEPS) comes to the fore. This study aims to analyse electric motors, one of the HPS and DEPS equipment, in detail. In this study, HPS gains are described by performing application load tests on electric motors and diesel engines in detail. Consequently, this article found that HPS and DEPS systems will be used more widely in the maritime industry in the future, especially on tugboats operated at low loads for most of their operating time. This paper will be a prominent source for researchers and maritime sector stakeholders whose studies are concerning HPS and DEPS, particularly on electric motors.
