Hazard and Operability Study (HazOp)

Reducing client's risks to as low as reasonably practicable

The Boots & Coots Hazard and Operability Study (HazOP) is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation. The best time to conduct a HazOP is when the design is fairly firm. However, HazOPs can be done at any stage after the design is nearly firm.

The team focuses on specific points of the design (study nodes), one at a time. These study nodes include individual items of equipment or control systems. At each of these study nodes, deviations in the process parameters are examined using the guide words. The guide words are used to help ensure the design/process is explored thoroughly. Thus, the team must identify a fairly large number of deviations, each of which must then be considered, so their potential causes and consequences can be identified. The HazOP multidisciplinary team methodically “brainstorms” the design, following the structure provided by the guide words and the team leader’s experience.

Boots & Coots uses a Risk Assessment Software, a recently released system, which applies the latest concepts in risk management to the widely accepted and proven BowTie methodology. It supports and extends the AS/NZS 4360 Risk Management standard currently accepted as the world premier risk management standard. In addition, the new IADC HSE Case Guidelines for drilling operations edition of BowTieXP® software was released together with the official publication of the new global IADC HSE Case Guidelines. The new IADC Case Guidelines not only help to ensure operation integrity management but also assists drilling contractors with HSE cases that are based on a global standard rather than local regulation.

Boots & Coots’ HazOps will be conducted using a BowTieXP software application analysis. The consequences can be assigned a risk ranking according to the client’s risk matrix and ultimately to demonstrate the organization’s risks are reduced to as low as reasonably practicable (ALARP).
