| Description |
The Offshore Federal Oil & Gas infrastructure includes over 4,000 platforms, some extending in life over 40 years. Extreme wave crests and wave heights beyond those envisioned during of 100-year storm events were experienced during recent hurricane events and are believed to have resulted in the destruction and/or damage of hundreds of offshore fixed and floating structures. The objective of this research proposal was to develop a procedure to estimate local and global green water loads at the point of contact between extreme wave crests and offshore structures. |
| Progress |
Project was initiated in may 2006 and completed in October 2008. |
