Summary
Following Hurricane Ike, damaged flanged wellhead connections leaked, and one subsurface safety valve initially failed to isolate downhole pressure. The alert examines hurricane loading and failed supports, and recommends visual inspection before restarting wells, followed by isolation, repair and wellhead pressure testing where excessive loading is suspected.
