How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. 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 Ricardo WAVE, GT-SUITE (GT-Power), SolidWorks, ANSYS Fluent and Dynojet Power Core, in free, academic or evaluation versions. Tests are studied on real procedures: static sound measurement in the paddock, dyno power comparisons after an exhaust change and weld inspection on titanium headers. Assessment is continuous by module plus the final project.
Standards covered: UNECE Regulation No 41, UNECE Regulation No 92, ISO 5130, ISO 362-2, Delegated Regulation (EU) No 134/2014, Regulation (EU) No 168/2013, FIM technical regulations.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.

Frequently asked questions
The programme totals 300 hours over 3 months. You set your own pace within each intake, and your tutor helps you plan the workload around your job.
You work with Ricardo WAVE, GT-SUITE (GT-Power), SolidWorks, ANSYS Fluent and Dynojet Power Core, using free, academic or evaluation versions. Your tutor indicates the free alternative wherever one exists.
A SEIUM Institute certificate, awarded on passing the continuous assessment and the final project. It is SEIUM's own qualification, not an official state degree; its recognition depends on the programme completed and the regulations of each country.
Yes. Modules passed are recognised in a higher programme in the same area (postgraduate diploma or master's). Ask about the recognition policy when you enrol.
No prior qualification is required; you need an internet connection, a computer that can run the programme software and English sufficient to read technical standards.
Start dates are set by SEIUM's faculty for each intake. Our admissions team will confirm the next available date when you apply.
