![]() The Marine Technology Society, an organization of ocean engineers, technologists, policymakers and educators, also expressed concern to OceanGate about the size of the Titan, the construction material and the fact that the prototype wasn’t being examined by a third party. “Nondestructive testing is how you would then assess those structures and say, ‘OK, they’re still viable,’ or, ‘they’re still susceptible.’” “Once this thing is going down and going under stress, it’ll affect those materials, it’ll affect those composites,” Couture said Friday. Ultrasonic testing can help spot areas inside the structure where the composites are coming apart, said Neal Couture, executive director of a professional organization called the American Society for Nondestructive Testing. He advocated for “nondestructive testing,” such as ultrasonic scans, but the company refused. ![]() OceanGate was also warned that a lack of third party scrutiny of the vessel during development could pose catastrophic safety problems.ĭavid Lochridge, OceanGate’s then-director of marine operations, said in a 2018 lawsuit that the company’s testing and certification was insufficient and would “subject passengers to potential extreme danger in an experimental submersible.” But we do have issues with composites and the fact that composites fail in slightly different ways than other materials,” he said. Yes, composites are extremely long lasting. ![]() It also said the vessel was designed to dive four kilometers (2.4 miles) “with a comfortable safety margin,” according to court documents.īut carbon composites have limited life when subject to excessive loads or poor design which leads to stress concentrations, Graham-Jones said. OceanGate promoted the Titan’s carbon fiber construction - with titanium endcaps - as “lighter in weight and more efficient to mobilize than other deep diving submersibles” on its website.
