BALTIMORE — A containership the length of more than three football fields has finally been pried from the muddy bottom of the Chesapeake Bay more than a month after it ran aground.

BALTIMORE — The U.S. Coast Guard prepared a second attempt to free a stranded container ship March 30, more than two weeks after it ran aground in the Chesapeake Bay.

The Ever Forward, a 1,095-foot cargo carrier with more than 4,000 full shipping containers, is the largest ship to have ever run aground in the Chesapeake Bay, and freeing it is an arduous and cumbersome process. The first attempt to refloat the ship will begin at noon March 29.

Officials say it could take days or weeks to free a containership stranded near Gibson Island in the Chesapeake Bay since the evening of March 13.

A year after a giant containership got stuck in the Suez Canal for almost a week and disrupted global trade for months, another Evergreen Marine Corp. vessel has run aground, this time near the U.S. capital.
