Electrical HAZOP (EHAZOP / SAFOP) Studies Want us to call you
- A Electrical System Hazard and Operability (EHAZOP/SAFOP) study is a structured and systematic examination of a planned or existing electrical system in order to identify and evaluate hazards that may represent risks to personnel or equipment, or prevent efficient operation.
- Qualitative technique based on guide-words and is carried out by a multi-disciplinary team during a set of discussion based sessions
Elements: Electrical HAZOP / SAFOP
SYSOP (System Operability)
The functioning and operation of the system and components are reviewed.
- The protection and control schemes and deficiencies in the design that affect operability and maintainability of the system is analyzed.
- The SYSOP study involves subdividing the complete electrical power system into a number of discrete ‘elements’ or systems, each of which is assessed by the review team, using guidewords.
- The review team agrees the location and possible causes of the deviations/concerns, the results and consequences .If there are mitigations or safeguards, and these are noted
SAFAN (Safety Analysis)
- The safety of all categories of persons, possibly coming into contact with the electrical installation/system is reviewed.
- The team assesses the possible situations where people (Outside Persons, Non-Electrical Company Staff and Contractors and Electrical Company Staff and Contractors) might get exposed to danger.
- The risks of an electrical installation are strongly linked to the degree of access or exposure permitted to the electrical equipment.
- SAFOP team identifies and agrees the exposure situation permitted in the design and if there are mitigations or safeguards, these are noted for the project team to action.
OPTAN (Operator Task Analysis)
- The evaluation of the electrical installation the required tasks of operational staff is done in this category.
- It analyses an Operator's anticipated response to hist ask by assessing the ability of that Operator, his equipment and instructions to give optimum performance with a minimum of error. The findings are noted in the worksheet
