How you'll learn
A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so you can combine it with your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is KISSsoft, Romax, MASTA, ANSYS Mechanical and MATLAB, in free, academic or evaluation versions. Testing is studied through real procedures for transmission test benches, loss-of-oil run tests and oil and particle analysis. Assessment is continuous by module plus the final capstone project.
Standards covered: ISO 6336, AGMA 2001-D04, CS-29, AGMA 911, ISO 281, EN 9100 and MIL-PRF-23699.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
