Course on Overdrives in Heavy-Duty Vehicles
Online 300-hour course on overdrives in heavy-duty vehicles. 6 modules covering Regulation (EU) 2019/1242 (CO2 emissions from heavy-duty vehicles), Regulation (EU) 2017/2400 (VECTO certification) and VECTO. Assigned tutor and open enrolment.
Course on Overdrives in Heavy-Duty Vehicles — studying from Singapore
Singapore's off-road and special vehicle sector is smaller than in larger industrial economies but serves port operations, construction, airport ground support and marine logistics. Equipment such as cranes, forklifts and specialised port machinery is maintained and developed locally. The Ministry of Manpower and the Land Transport Authority set safety and operating standards. Employers include port operators, construction groups and heavy equipment dealers.
Fees for Singapore: S$920 (Singapore dollar), with instalments and employer sponsorship available.

Questions from Singapore
Will this qualification be recognised by professional bodies in Singapore?
SEIUM's qualifications are private, not official state degrees, and are not accredited by any national body in Singapore. Engineers may seek Professional Engineer registration through the Professional Engineers Board, and machinery work may also involve Workplace Safety and Health requirements set by the Ministry of Manpower. Recognition of a private qualification is decided by employers or the relevant body.
How might this training be used by employers in Singapore?
Singapore's construction, port, logistics, marine and industrial sectors use heavy machinery and special vehicles, so these skills may be relevant to maintenance, design and equipment engineering roles. The programme does not guarantee employment. Employers usually weigh practical experience, safety knowledge and project work alongside any qualification.
Can I study this alongside a full-time job, and can my employer help fund it?
Study is fully online and in English, with an assigned technical tutor, so you can fit it around work from home in Singapore. Workload ranges from 300 to 1,900 hours depending on the programme. Fees can be paid in instalments, and employer sponsorship is possible; many Singapore employers fund job-relevant training, so ask your management.

How you'll learn
Fully 100 % online training 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 programme with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is VECTO, AVL CRUISE, MATLAB/Simulink, advanced Excel, in free, academic or evaluation versions. Tests are studied using real fuel consumption simulation procedures with different final drive ratios, gearbox diagnostics in the workshop and driving data analysis. Assessment is continuous 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 role of long gear ratios in heavy-duty vehicles.
Describe the components and operation of the overdrive.
Select transmission ratios according to the vehicle's mission.
Apply driving techniques to maximise efficiency.
Diagnose and maintain overdrive systems.
