ABSTRACT
Introducing new work processes in an Integrated Operations (IO) environment triggers important changes and managing them can be challenging. IO can also pose a challenge for major accident prevention because of, for example, the complexity of organizing work and an inadequate flow of information. The Risk Assessment in IO project aimed to address risk related to the new ways of organizing work brought about by the IO context and specifically, how to assess and express risk in such a context. In hindsight, the interdisciplinary aim of the project clearly developed into a multidisciplinary approach. Although several attempts were made to cross traditional boundaries between disciplines and schools of thought and integrate knowledge from different disciplines, it proved to be a difficult task. Risk assessment methods have been strongly influenced by engineering practices. They are rooted in all phases of the lifecycle of an oil and gas installation, ranging from quantitative design assessments to qualitative, operative assessments.
