... To assist North Sea operators a risk-based approach for the risk in a storm was required to enable comparison with other operational risks to ensure an ALARP position was reached. A review of Gulf of Mexico approaches highlighted the most common approach being a ‘T-time’ approach. This method...

... campaign is ongoing for the second year and the results reported here are based on data from the first hurricane season (2022-2023). Results for the first season did not include any extreme storms which means that direct seabed impact or other direct evidence of unexpected behavior in extreme conditions...

The study focuses on a Floating Storage and Offloading (FSO) unit, experiencing significant forces during the storm, which recorded the highest...

..., and tropical storms travel through the Gulf of Mexico (GOM), interrupting operations of the fixed and floating platforms. In the hurricane season of 2021, weather developments have covered almost all regions in the GOM. The Bureau of Safety and Environmental Enforcement (BSEE) requires a number of steps...

.... Evaluated storms ranged from major cyclones to tropical storms that developed close to the offshore location of interest. The program performed evaluations from initial formation of the weather system through to the disconnect and sail away of the FPSO. An evacuation disconnect was deemed successful if all...
