Turbochargers in Off-Road Machinery Course
Online 300-hour course in turbochargers in Off-Road machinery. 6 modules covering Regulation (EU) 2016/1628 (non-road mobile machinery engines, Stage V), SAE J1826 (turbocharger testing on gas bench) and GT-SUITE. Assigned tutor and open enrolment.
Turbochargers in Off-Road Machinery Course — studying from South Africa
Mining, agriculture and construction make off-road and specialised machinery central to South Africa's economy. Mining equipment manufacturers and service providers support the country's extensive gold, platinum and coal operations, while agricultural machinery serves commercial farming. Engineers working on heavy vehicles and special machines focus on hydraulics, drivetrains and durability under harsh conditions. The South African Bureau of Standards and the Mine Health and Safety Council set relevant standards and safety requirements.
Fees for South Africa: R 10 200 (South African rand), with instalments and employer sponsorship available.

Questions from South Africa
Will a SEIUM qualification be recognised by the professional bodies in South Africa for this area?
SEIUM qualifications are private and not accredited by any South African body. Engineering registration is handled by ECSA, and machinery safety standards are linked to SABS and the Department of Employment and Labour's regulations. Recognition of a private qualification is decided by employers or the relevant body, so confirm this with them before you enrol.
How might this qualification be used by employers in South Africa in off-road and special vehicles?
Mining, agriculture, construction and vehicle-conversion firms value practical machinery knowledge and proven problem-solving. A private qualification can support your application, especially with hands-on experience, but it carries no official status. Its weight depends on each employer, so ask potential employers in your field how they would view it.
Can I study this programme alongside full-time work from South Africa, and is there a time zone or language issue?
The programme is 100% online and in English, so you can study from home without a student visa. Master's programmes take 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours. Each student has an assigned technical tutor, fees can be paid in instalments, and employer sponsorship is possible. Check time-zone and workload expectations with SEIUM directly.

How you'll learn
100 % online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the intake, which makes it compatible with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is GT-SUITE, Jaltest Diagnostics, MATLAB/Simulink, Cat SIS / Cat ET, Advanced Excel, in free, academic or evaluation versions. Tests are studied using real diesel engine test bench procedures, inspection of clearances and rotor imbalance, and laboratory oil analysis. Assessment is continuous per module plus the final integrating project.
