How you'll learn
100 % online training on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the enrolment period, which makes it compatible with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Simcenter Testlab, ARTeMIS Modal, ANSYS Mechanical, MATLAB, in free, academic or evaluation versions. Studies are based on real modal hammer testing procedures, operational modal analysis in navigation and MAC correlation between model and measurement. 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 concepts of natural frequencies and mode shapes.
Carry out numerical modal analyses of the hull using finite elements.
Plan and carry out experimental modal tests.
Apply operational modal analysis techniques on ships.
Correlate models and measurements using the MAC criterion.
Where this takes you
Requirements
- No prior degree is required.
- Internet connection and a computer capable of running the programme's software.
- A sufficient level of Spanish to follow the reading of technical standards.

Frequently asked questions
The programme totals 300 hours spread over 3 to 5 months. That is between 10 and 15 hours per week on average, compatible with a full-time job.
You will work with Simcenter Testlab, ARTeMIS Modal, ANSYS Mechanical, MATLAB. Free, academic or evaluation versions are used, and the tutor will indicate the free alternative where one exists.
A SEIUM Institute own diploma upon passing the continuous assessment and the integrating project. It is in-house training, not an official Ministry qualification.
Yes. Modules passed in a course or postgraduate diploma in the same area are credited towards the higher programme. Check the recognition policy when you enrol.
