Organizational risk indicators are proposed as a tool for risk control duri
ng operation of offshore installations, as a complement to QRA-based indica
tors. An organizational factor framework is developed based on a review of
existing organizational factor frameworks, research on safety performance i
ndicators, and previous work on QRA-based indicators. The results comprise
a qualitative organizational model, proposed organizational risk indicators

tion on risk. The risk indicators, when validated, will aid in a frequent c
ontrol of the risk in the periods between the updating of the quantitative
