Hello FMagyar,

Thxs for your reply. Yep, perhaps I was unduly optimistic--I can still recall the photo of the Thunderhorse platform badly hammered and listing heavily...A platform able to withstand a CAT 6 might be impossible to engineer.

Maybe not. Though the EROEI for the oil recovered by such a rig would probably be more negative than the actual impact of a Cat 6 ;-)

After hurricane Dennis, Thunderhorse was listing due to a fault in the construction causing some of the ballast tanks to overfill when evacuation procedures were followed; this was not a direct consequence of hurricane winds or waves.

Shell's Auger platform logged sustained 125 mph (Cat 3) winds before the anemometer blew out when the eye of Ike passed by. It was back online within weeks. These platforms are designed for cat 5 survival. "Typoon, a small spar, and many older shelf platforms, however didn't make it through 2005.
