The huge barge has to be moved into place and sunk in order to seal the system from storm surge sweeping into Lake Borgne from the Gulf of Mexico, a process that takes more than nine hours and must begin four days before a hurricane strike is expected. In repeated tests, the barrier has yet to function reliably.
