Security Studies (Hazard and Operatibility, Hazop)

Most insurers are asking authorities and operating companies to conduct studies and risk assessments during the design and installation of each project.

A thorough risk identification is key to effective management needed to implement control measures or even to redesign the project to mitigate those risks.

Our team delimits areas, systems or subsystems that are subject to study and identifies threats beyond the design of a process or its subsequent amendments, we conduct a detailed examination of the engineering process in new or existing facilities in order to assess the potential risks of such operations, the malfunction of equipment and the consequences of its effects on a plant and its environment.


estudios seguridad Breton EngineeringBy using tools such as HAZOP, HAZID, FMEA WHAT-IF supported by specific software, we are able to identify the potential risks in an installation and apply the best available techniques to establish the accident scenarios arising from such risks (such as those published in the CPR 18E “Purple Book” TNO or in “Guidelines for chemical process quantitative risk analysis” of CCPS / AICHE)

Then we incorporate this data to a suitable simulation model and calculate the unintended consequences of the hypotheses to predict the physical effects of each.

The reliability of a simulation is not guaranteed only by using the best software. It will depend greatly on the professionals who generate and interpret the different tests. Our team work with specific models for calculating effects of accidents in the chemical industry such as EFFECTS, PHAST, DEGADIS, HEGADAS or ALOHA.


Quantitative risk analysis (QRA) is a key element tool applied in safety management and risk control throughout design, construction, operation and decomissioning of all industrial activity in order to achieve safe operation and major hazard control.

The ACR not only stands as an indispensable tool in the internal management of the security level of a system but also is an important element in urban planning decision.
. QRA typically assess an entire plant, platform, field, transportation system or a specific system or a particular operation. 

SOLUTIONS. Cost / benefit analysis

Based on the result of the ACR and the information obtained in the preliminary stages, we propose a series of actions in order to reduce the installation risks.

Additionally, we also conduct a cost/benefit analysis which establish the risk reduction provided by each recommendation against the investment required.

The result of this process is a valuable decision-making tool that clearly illustrates the impact of each investment in improving safety and helps to prioritize the proposed measures.


How to act if, despite everything, there is an accident?

Foreseeing emergency situations require contemplating all possible risks, not only the ones associated to the specific activity but the ones related to the environment as well. Hence we feel we are ready for this challenge due to our extensive experience working with all kind of risks in many different environments.
