Rescue of 4 crew members a success, now how to move a disabled 600 foot cargo ship

ST. SIMONS, Ga. (FOX 5 Atlanta) - One of the rescue coordinators who helped save four crew members from an overturned ship off the Georgia coast says the men are "doing well" after being trapped aboard the ship for more than a day.

Salvage expert Sylvia Tervoort was part of a private team that assisted the Coast Guard in the rescues Monday of the South Korean crew members still aboard the Golden Ray.

Tervoort said the men waited roughly 30 hours for rescue in tough conditions -- in the dark, breathing air filled with fumes in the ship's engine room, in sweltering temperatures of nearly 150 degrees (65.5 Celsius).

The Golden Ray rolled onto its side early Sunday after leaving the Port of Brunswick loaded with more than 4,000 vehicles. Coast Guard Petty Officer 1st Class Luke Clayton says removing the ship will likely take weeks. The port remains closed.

The ship remains stuck in St. Simons Sound, closing the busy port while shipping hazards are evaluated.

Altamaha Riverkeeper, a group that works to protect water in the area from pollution, posted on Facebook that it will keep monitoring the salvage operations.
