could what happen again? In order for me to answer you have to be more descriptive!
How did the Exxon Valdez sink?
The Exxon Valdez ran aground on the Bligh Reef. The ships collision radar was broken and not turned on at the time (had it been on the ship would not have hit the reef). The ship was also outside normal shipping lanes to avoid icebergs that were thought to be in the area.
