Business Sectors (Suites): Downstream Operations
Developed by: Cogent
Approved on: 29 Mar 2019


​This standard is about your competence in handling non-routine information relating to the condition of process plant and equipment. This includes rotating, non-rotating and storage, heat transfer and control equipment.

This standard deals with the following:

1 Diagnose faults affecting plant conditions
2 Take non-routine field readings on plant conditions
3 Communicate non-routine information on plant conditions

During this work you must take account of the relevant operational requirements and safe working practices AS THEY APPLY TO YOU.

This Standard is suitable for those working in the downstream fuel environment.
