What People are Saying

Albert Alvero Project Engineer

The content of this course is really good and it gave me the foundations I need.

Cameron Roberts Process Engineer

This course provides an excellent foundation for those who may be required to deal with SIFs in the industry. The content is all applicable to industry and the real world.

Krishnan Jayakumar Process Engineer

Excellent course for operation, design and process engineering. Subjects well designed, organised and presented perfectly with practical examples.
