Abstract:

HAZOP studies are conducted to assess the safety and operability of technical systems. A significant amount of staff effort and corresponding costs are required to carry out HAZOP studies, with a large proportion of the workload consisting of often repetitive "drudge work". This article demonstrates how these repetitive tasks can be automated by means of a knowledge-based approach and shows the results achieved by using this approach in an initial prototypical implementation. The automated analysis is based on an XML file that contains the description of a plant according to IEC PAS 62424 (CAEX). © 2009 Inside Publishing. All Rights Reserved.
