Aim

The course is intended to give an overall overview of methods and theories for the identification, analysis and minimisation of risks, as well as mechanisms and calculus methods for hazardous events within the chemical industry.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• Comprehend the complete procedure of risk assessment within the process industry.
• Be able to account for the concepts risk chemicals and risk processes.
• Understand when and why a risk assessment is required.
• Account for all the steps included in a technical risk assessment.
• Understand how a hazardous event is propagated in a process plant.
• Be able to evaluate and compare risks in light of criteria of acceptable risks
• Understand how safety systems may be applied to minimize risks.

Competences and skills
For a passing grade the student must

• Select required tools for a required risk assessment.
• Be able to carry out risk qualitative as well as quantitative risk assessments.
• Be able to perform analyses of consequences of an accident.

Judgement and approach
For a passing grade the student must

• Perform in-depth practice and calculation of HazOp, fault-tree analysis, dispersion modeling and runaway reactions.
• Complete a project work of a risk assessment on an industrial plant, including a written documentation and an oral presentation.

Examination details

Grading scale: TH - (U, 3, 4, 5) - (Fail, Three, Four, Five)
Assessment: Written examination, calculation and project assignments. The grade is based on the written examination and addition of up to 0.5 from the calculation and project assignments.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
