The carbon fiber hull of the experimental submersible that imploded en route to the wreckage of the Titanic had imperfections dating to the manufacturing process and behaved differently after a loud bang was heard on one of the dives the year before the tragedy, an engineer with the National Transportation Safety Board said Wednesday.
Engineer Don Kramer told a Coast Guard panel there were wrinkles, porosity, and voids in the carbon fiber used for the pressure hull of the Titan submersible. Two different types of sensors on Titan recorded the “loud acoustic event” that earlier witnesses testified about hearing on a dive on July 15, 2022, he said.
