  • Flexible: short interactive sessions over the Internet which you can attend from your home or office. Learn while you earn!
  • Practical: perform exercises by remotely accessing our labs and simulation software
  • Expert instructors: instructors have extensive industry experience; they are not just 'academics'
  • No geographical limits: learn from any location, all you need is an Internet connection
  • Constant support: from your instructor(s) and a dedicated Course Coordinator for the complete duration of the course
  • International insight: interact and network with participants from around the globe and gain valuable insight into international practice 

Benefits of eLearning to Employers

  • Lower training costs: no travel or accommodation necessary
  • Less downtime: short webinars (60-90 minutes) and flexible training methods means less time away from work
  • Retain employees: keep staff who may be considering a qualification as full time study
  • Increase efficiency: improve your engineering or technical employees’ skills and knowledge
  • International insight: students will have access to internationally based professional instructors and students


How Does it Work?

EIT eLearning courses involve a combination of live, interactive sessions over the Internet with a professional instructor, set readings, and assignments. The courses include simulation software and remote laboratory applications to let you put theory to practice, and provide you with constant support from a dedicated Course Coordinator.

Practical Exercises and Remote Laboratories

As part of the groundbreaking new way of teaching, our online engineering courses use a series of remote laboratories (labs) and simulation software, to facilitate your learning and to test the knowledge you gain during your course. These involve complete working labs set up at various locations of the world into which you will be able to log to and proceed through the various practical sessions.

These will be supplemented by simulation software, running either remotely or on your computer, to ensure you gain the requisite hands-on experience. No one can learn much solely from lectures, the labs and simulation software are designed to increase the absorption of the materials and to give you a practical orientation of the learning experience. All this will give you a solid, practical exposure to the key principles covered and will ensure that you obtain maximum benefit from your course.

Mechanical engineering encompasses the conceptualisation, design, manufacture, control and maintenance of machines ranging from a conveyer, space shuttle to nanotechnology based objects. In broad terms, mechanical engineering channels the energy and forces in nature to the service of people. The fields in which mechanical engineering professionals operate are wide - ranging from oil and gas, power generation, water utilities, process plants, mining, pharmaceuticals, manufacturing and defence.

A diploma in mechanical engineering is ideal for anyone wanting to get involved in the general engineering (whether design or maintenance) of large plants, especially as a plant engineer. Recently, mechanical engineering has begun to include many new systems in the electronics and control arena such as programmable logic controllers (PLCs) and SCADA as these are critical to the control of mechanical devices.

Students in the EIT School of Mechanical Engineering can study an Advanced Diploma of Mechanical Engineering with subjects that include: mechanics, structural engineering, drive systems, rotating equipment, hydraulics, pneumatics, lubrication engineering, HVAC, pumps, compressors, machinery safety, energy efficiency and renewable energy sources.

The focus of EIT's School of Mechanical Engineering is in providing students with both deep and broad skills in mechanical engineering technology, focusing on real systems. Whilst there is probably not a shortage of theoretically orientated practitioners in mechanical engineering, there is a need for highly skilled, practically oriented engineers, technologists and technicians, due to the rapidly increasing use of new technologies which are becoming a key component of all modern plants and equipment. Studying our mechanical engineering diploma online means you don't have to take extended periods away from existing work commitments.
