How you'll learn
100% online training on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake, making it compatible with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MATLAB/Simulink, DNV Nauticus Machinery, ETAP, PLECS, in free, academic or evaluation versions. Tests are studied using real procedures for torsional analysis of shaft lines with PTO, simulation of PTO, PTI and PTH operating modes, and savings studies with shaft generators. Assessment is continuous per module, plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Understand the principles and modes of PTO and PTI systems.
Select suitable electrical machines and converters.
Integrate the system mechanically with the shaft line.
Analyse the torsional vibration of the installation.
Design the control logic and mode management.
Where this takes you
Requirements
- No prior qualification is required.
