Course Objectives

Training in Process Safeguarding (Safety in Process Design) covers a wide range of subjects with many applications in hydrocarbons and chemical processing. As the name suggests, it addresses the process engineering and safeguarding aspects of processing equipment/units. The process design safety orientation of the participant results in safe process designs.

Who should attend?

This training is ideal for HSE engineers, process engineers, mechanical and piping engineers, instrumentation and automation engineers, project engineers and managers, operations and maintenance engineers.
