Examples from the CAPE-SAFE Integration with Plant Modeling

Equipment-Class is Changed Validate plant model changes weather it require hazard evaluation process or not. From Modeling To Safety 

Safety criteria is changed against control valve classes Modify the safety constrain associated with the control valve class From Safety To Modeling 

Develop new safety constraints Define and associate safety constraints as associated OCE to model elements From Safety To Modeling 

Within the safety evaluation practices, there are many solutions that are based on identifying the initial event, which is used as an input to the dynamic simulation to conduct process simulation to highlight any abnormal situation that may arise. Such abnormal situations can be quantitatively assessed to show the severity level and risk. Such experiment has been made by many researchers as a part of the process safety design i.e. IPL design. Also such information are important for operator to assist in his daily operation. 

Safety evaluation results are very essential for operator. In fact such data can t be found in any other place within the PEEE. Hence, providing such data can add value to operator in his daily work. HAZOP results can help operator in understanding the cause and consequence of the different failures that may occur to any part of the plant process. Operator can use this data to decide the actual cause of any given error, and hence, can decide the most suitable corrective action. For that hazard evaluation results are shared with the operation environment. From operational systems, the daily failure in any part of the plant
