99556 - Mechanical Plant Design M

Learning outcomes

The student acquire the skills for designing and commissioning mechanical industrial plants. Particularly, the student will be able to: • Design the executive project of the industrial mechanical plant starting from the Process Flow Diagram (PFD); • Develop the test activities for the plant commissiong ; • Prepare the technical documentation necessary for the certification of the mechanical plants. The student also knows: The set of rules that oversees the placing on the market of the plant.

Assessment methods

Achievement will be assessed by the means of a final exam. This is based on an analytical assessment of the “expected learning outcomes” described above. In order to properly assess such achievement, the examination is based on a written test composed of three questions.

The rating is assigned based on the overall assessment of the whole test.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents.

To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language.

A failing grade will be awarded if student shows knowledge gaps in key-concepts of the subject, inappropriate use of language and failures in the analysis of the subject. Then the exam result not sufficient if at least one question is not sufficient.

Usually the written test correction immediately follows the written test end. So, it is possible to make further oral questions to the students to better assess their skills and to better define the final evaluation.
