Ships have become increasingly automated so problems encountered with the application of automated systems, and the failures of automation and associated processor-based motor starters, are factors that could contribute to future marine accidents

This interactive training package should be used to enhance and supplement your knowledge and skills. It will provide familiarisation with a variety of electrical appliances that are part of, or associated with, modern marine starter safety and control circuits.

Using the detailed and accurate simulators, which are incorporated as part of this package, you will be able to practice and refine your troubleshooting knowledge and fault finding skills.


This training package is appropriate for:

· Management level marine engineers

· operational level marine engineers

· electricians with a lack of experience

· engineering cadets

· electrical engineering cadets

· anyone who is starting to work with switchgear starters.
