ENTANGLEMENT OF THE SUBMERSIBLE JOHNSON SEA LINK WITH SUBMERGED WRECKAGE OFF KEY WEST, FLORIDA ON OR ABOUT 17 JUNE 1973 WITH LOSS OF LIFE. MARINE CASUALTY REPORT
On June 17, 1973, near Key West, Florida, the submersible JOHNSON SEA LINK became entangled in a cable of the wreckage of the scuttled destroyer U.S.S. FRED T. BERRY. The JOHNSON SEA LINK had been attempting to retrieve a fish trap in the immediate vicinity of the wreckage. Before the submersible was recovered, more than 33 hours later, two of the four persons on board had died as a result of carbon dioxide poisoning. The National Transportation Safety Board determines that the probable cause of the accident was the fouling of the starboard spring-loaded moused hook and other appendages on the submersible with a cable attached to the aftermost flagpole of the scuttled destroyer. Contributing to the carbon dioxide fatalities was the inadequacy of the carbon dioxide absorbent system in the dive chamber, and the lack of suitable rescue equipment was a factor in the inability to provide a timely rescue.
