The U.S. Coast Guard released its final report on the implosion of OceanGate’s Titan submersible in June 2023, finding problems at nearly every level.

The 335-page report was the result of over two years of investigation, including a two-week hearing held last year. The report found problems ranging from a toxic work environment to a failure to follow engineering protocol. OceanGate CEO Stockton Rush, who was among the five crew members who died in the implosion, was held primarily responsible.
