If I remember correctly the Nautilus broke free of it's mooring lines at least once during a hurricane. Since it was a moored rig I believe it had been evacuated and nobody was on board when it drifted off location. FREEDOM!What a coincidence I am on the West Neptune as well.)
I did 8 years on the Nautilus, I believe they ballasted down during storms and the bottom of the rig was around 60 foot off the water.
