As of April 20, it's been three years exactly since BP's Deepwater Horizon offshore oil rig exploded in the Gulf of Mexico, killing 11 and pouring some 5 million barrels of oil into the sea.
Some coastal restoration and protection work has occurred since the 2010 disaster, funded by initial payouts from the oil giant and other responsible parties. But plenty of work has yet to be done, with potential opportunity for engineering and construction firms in the Gulf Coast area to help rebuild and restore the coastline. But how soon the complex financial, legal and regulatory issues will untangle is not entirely clear.
