Monitoring and analysis of hazards using HAZOP-based plant safety model

Operator Support for Abnormal Situations Using Safety and Reliability Knowledge

“…By fulfilling the conditions specified in the applicability profile, the piece of advice is assumed to be relevant. Careful definition of the applicability profiles is required in order to achieve a powerful disturbance analysis capability (Heino et al 1994). The ASM advice is also linked to a process unit with a position within the process diagram.…”

“…Venkatasubramanian and Rich (1988) were pioneers in combining general and process specific knowledge in order to create a methodology which is suitable for practical use in industrial applications. Heino et al (1994) aimed to achieve the same objective by improving the utilisation of existing safety knowledge resulting from process safety and reliability studies.…”

“…The use of this information should be made simple and a part of normal process control and monitoring routines. The user interface should focus on providing tools for the efficient generation, storage and retrieval of information in a problem-oriented manner (Heino et al, 1994). User interface design, as well as system structure, can have a significant impact on the acceptability and utilisation of the system.…”

“…Heino et al (1994) aimed to improve the utilisation of safety and reliability studies. Later on, abnormal situation management, aided by operator's tools, has been studied further (Nimmo, 1995).…”
