Remember the Cougar Ace, the Mazda car carrier which tried to turn turtle and took the life of salvage surveyor?
There's an excellent article on how the car carrier, which took on a severe port list was brought back to even keel at Wired's High Tech Cowboys of the Deep Seas: The Race to Save the Cougar Ace:
By the end of the second day of pumping, the Cougar Ace is upright. A few days later, the owners come aboard to reclaim the ship. What initially seemed like a lost cause is now floating freely. It did not sink. Ninety-nine percent of its cargo is intact. There was no environmental disaster.How it was saved is a great read.
