How you'll learn
Training is 100% online on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the enrolment period, which makes it possible to combine the course with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Ansys Fluent, GT-SUITE, AVL BOOST, MATLAB/Simulink, in free, academic or evaluation versions. Tests are studied using real NOx measurement procedures on engine test benches, on-board verification of an SCR system, and a technical-economic comparison of Tier III measures. Assessment is continuous, module by 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.
Explain the NOx formation mechanisms in marine diesel and gas engines.
Compare primary and secondary NOx reduction measures.
Size an SCR reactor and its urea dosing system.
Integrate an SCR system into newbuild and existing ships.
Apply the NOx Technical Code and the Tier III certification schemes.
