Workers use barges and cranes to drive pilings into the Perdido Pass, in an effort to build a large gate to allow boats in and out of the pass and to guard against oil from entering the pass, at Orange Beach, Alabama June 14, 2010. British energy giant BP unveiled a plan on Monday it hopes will vastly increase the amount of oil it is capturing from its blown-out well in the Gulf of Mexico as President Barack Obama arrived there to assert leadership in clean-up efforts after the oil spill.
