Trimax,
It isn't just people who are scared of them. Risk evaluation isn't just the likely hook of damage it also includes the potential harm if something occurs. In
New Orleans they considered putting the off load point up the river close to downtown
New Orleans. Even assuming a very low likelihood of a catastrophic event occurring when you add in the loss of life and physical damage it would have been a catastrophic failure. The worst case scenario included blowing a hole through the River levee surrounding New Orleans which would have resulted in a change of course for the entire
Mississippi River. Placing a million people at risk, causing trillions in damage, and possibly shutting down the largest port in the world permanently.
The risk was considered to high even assuming a very low likelihood of it happening, so they repurposed an old sulphur mine to act as the
offshore connection.
