To reduce costs (by ca. 30%), increase production (by ca. 10%) and extend the life time (by ca. 5 years) of North Sea wells the Norwegian oil & gas industry is developing an infrastructure of "integrated operations" i.e. eOperations from control centers with reduced personnel on offshore platforms. New technology, new work processes and new knowledge are needed. Increased reliance on information technology introduces risks, with components of threat, vulnerability, and impact depending on how the transition to eOperations is managed. Simulation models show that the risk behavior of the system depends sensitively on how resources for work process development and knowledge ac-quisition are deployed. Understanding such dynamics facilitates decision-making to minimize security (and safety) risks.
