To monitor the development of the risk of major accidents of structures and maritime systems on the Norwegian Continental Shelf a set of incident indicators has been established. These indicators are given a weight related to the fatality risk predictions in order to develop a total risk indicator. Aggregated and weighted indicators as well as individual indicators are presented and evaluated. In addition indicators related to barriers are established giving a method to monitor the performance as a function of time, and to benchmark the participants in the industry. The present paper describes the method used in the risk level project to monitor the risk related with emphasis on structures and maritime systems, including hazards as wave in deck, vessel collisions and cracks on the structures. The paper further presents the actual development using the methodology, and the identified major contributors to the risk level.
