Offshore Indicators Major accidents
The objective of the work Measure the impact of the industry's HSE work. Contribute to identifying areas that are critical for HSE and where the effort to identify causes must be prioritised in order to prevent unwanted incidents and accidents. Increase insight into potential causes of accidents and their relative significance for the risk profile, to provide decision-support for the industry and authorities concerning preventive safety and emergency preparedness planning. The work may also contribute to identifying focus areas for amending regulations, as well as research and development.
