Course in Hydrostatics Applied to Agricultural Machinery
The Cabin Pressurisation Systems Course explores the design, operation and maintenance of systems critical to flight safety and passenger comfort. It covers the principles of pressurisation and depressurisation, control of airflow, pressure regulation and contaminant management within the cabin. It delves into identifying and resolving system faults, from leaks to malfunctioning valves and compressors, using flow diagrams and simulations for analysis. The course emphasises the importance of compliance with aeronautical regulations and the safety measures associated with the operation and maintenance of these systems.
The programme includes a practical approach using diagnostic tools and test equipment, simulating real-world scenarios to ensure in-flight safety and passenger comfort. It prepares professionals such as aircraft maintenance technicians, aircraft systems engineers and flight safety specialists. The training covers emergency management related to pressurisation and the application of QRH (Quick Reference Handbook) procedures for risk mitigation.
Course in Hydrostatics Applied to Agricultural Machinery — studying from New Zealand
Off-road and special vehicle engineering is a major strength in New Zealand, reflecting the importance of agriculture, forestry, mining and construction. Manufacturers and fabricators in the Waikato and Canterbury produce tractors, harvesters, dairy equipment and specialised machinery, many of which are exported worldwide. Engineers in this field work on design, testing and safety compliance for equipment used on farms, in plantations and on remote worksites.
Fees for New Zealand: NZ$1,470 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Which New Zealand bodies relate to off-road and specialist vehicle engineering?
Engineering New Zealand is the main professional body, and vehicle compliance is handled by the NZ Transport Agency Waka Kotahi. Heavy machinery and certain specialist vehicles can also fall under WorkSafe New Zealand rules. SEIUM's qualifications are private and not accredited by any national body, so employers and regulators decide their value.
Who hires off-road and special vehicle engineers in New Zealand?
Employers include forestry and agricultural equipment firms, mining and civil construction contractors, fabrication shops, and emergency or utility vehicle fleets. Practical design, safety and maintenance skills are central to hiring. A SEIUM qualification may help, but its weight depends on the employer.
How does the study load work for someone with a job here?
The programme is fully online, so you can study around work from anywhere in New Zealand without a student visa. Specialist courses take 300 hours, postgraduate diplomas 800 hours and master's programmes 1,900 hours. You get an assigned technical tutor, and fees can be paid in instalments or sponsored by an employer.

How you'll learn
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 intake period, making it compatible with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Siemens Simcenter Amesim, Automation Studio, MATLAB/Simulink (Simscape Fluids), Excel, in free, academic or evaluation versions. Tests are studied using real procedures for measuring pressures and flows in a closed circuit, diagnosis of hydrostatic pumps and motors, and a hydrostatic transmission test bench. Assessment is continuous by module, plus the final integrative project.
