Integrated electronic documentation for decision support insafety-critical plant operations

摘要

Due to the nature of petrochemical plants, automation alone cannotminimise the risk of safety-critical incidents. When addressing hazardmanagement, people issues, the information needs of decision makers, inparticular those of the operators, the integrity of plant documentation,and management concerns need to be considered in an integrated way, withcomputer software used as a means to implement improved support systems.In order to identify operator decision support requirements, user,information and software concerns are outlined, and specification andimplementation aspects of improved decision support systems based onplant documentation in electronic form are discussed. A particularfeature of such a system is the ability to provide operational staffwith online access to hazard and operability (HAZOP) analysis resultscarried out as part of design activities
