Training Marine Propulsion: Electrical Drive Characteristics (module 4)

The training series Marine Propulsion Systems is a unique technical and international oriented training for those who wish to acquire in-depth knowledge of the design of different marine propulsion systems. Topics during the modules range from different power plant concepts and components to integrating components into properly matched propulsion systems. Working principles and characteristics of propulsors, internal combustion engines and electric power generation and distribution systems will all be dealt with throughout the training series. The 3rd module is about matching engines with propulsors including off-design operation of propulsion systems.

The fourth module ‘Electrical Drive Characteristics’ will provide the participants with a thorough understanding of the working principles of electrical power generation and distribution systems.

All modules can also be followed individually.


During this module the participants will learn about electric power systems and their main design aspects. The difference in electrical machines (such as AC and DC) will be explained, their working principles, as well as their components and several mechanical issues in the design and installation. The relation between machines, components, operating conditions and electrical propulsion concepts will be described and illustrated by means of real examples installed on board of vessels. Safety measures in design, installation and use of the electrical drive systems are an important topic and will be mentioned throughout the course. Knowledge of basic physical and electrical principles and theory required to understand the working principles of electrical propulsion systems will be explained by the teacher. The theory is practised by means of exercises during the module. At the end of this module the participant will be able to decide which type of electrical drive component and/or system will be suited best for a particular vessel design.

Target group

This module is intended for designers and (sales) engineers who deal with the integration or the design of marine propulsion systems and in particular electrical propulsion during concept design phase. It will also be of interest to people who come across aspects of these systems during their (daily) work and who wish to learn more about the working principle of marine electrical propulsion systems. The international setting offers participants a unique opportunity to gain knowledge and to network with colleagues, clients and suppliers. This enables them to position their companies even better in the international shipbuilding cluster.


Netherlands Maritime Technology (NMT) organises the fourth module in close cooperation with Bakker Sliedrecht Electro Industrie BV. The lecturer is Paul Bracké, former Manager Technology at Bakker Sliedrecht Electro Industrie BV.
