Q&A

• What critical analysis was conducted on the construction designs of the Ocean Gates Titan submersible?

  A critical analysis of construction designs, including an o-ring design and an atmosphere scrubbing system, was carried out, with concerns about potential cost-cutting and sidestepping regulations. There were also concerns about the quality of materials and a desire for a better learning process.

• What potential design flaws and concerns were identified in the Ocean Gates Titan submersible?

  The installation of titanium end rings in the vessel showed potential design flaws due to mismatched materials and poor workmanship, potentially leading to a failure. The use of epoxy glue to secure the interface was questioned, and concerns were raised about the quality of materials and testing processes.

• What was the analysis of the failure event in the Ocean Gates Titan submersible?

  The failure analysis revealed an event in the interface between the carbon fiber barrel and titanium rings, leading to the detachment of the forward ring and other components due to water pressure. It was suggested that the failure likely began at the front bulkhead, causing a chain reaction of pushing and cracking, which differed from previous simulations.

• What was revealed in the footage from the deep-sea vessel's ROV regarding the failure of the Ocean Gates Titan submersible?

  The footage from the ROV showed a failed pressure hull with shattered carbon fiber composite. The investigation suggested that the failure likely began at the forward Dome, resulting in an implosion rather than an explosion.

• What did the submersible footage reveal about the Ocean Gates Titan submersible?

  The footage showed a damaged but largely intact T tail cone, a non-pressurized section containing important equipment. Despite the assumption of failure due to carbon fiber, the US Navy had successfully built a carbon fiber submersible. Extensive engineering studies, including finite element analysis, were conducted, but imperfections in the transition from design to a working product were noted. Moreover, the communications were unreliable due to an acoustic modem.

• What insights does the investigation into the Ocean Gates Titan submersible's crushing at the Titanic wreck provide?

  The investigation provides insights from witnesses, including the lead engineer, a Scottish submersible expert, and the individual who put the submersible in the water. It details design decisions, operational mishaps, and the implosion of the submersible, shedding light on the failure.
