Coast Guard report: Titan submersible implosion that killed 5 "preventable"

• The incident in the North Atlantic Ocean sparked a massive search and rescue operation for the tourist submersible. Remains were later found and taken to St. John's in Newfoundland, Canada.

Zoom in: The investigation found the key contributing factors to the tragedy were OceanGate's "inadequate design, certification, maintenance and inspection process for the Titan," according to the Coast Guard.

• Other factors included "a toxic workplace culture at OceanGate" and "an ineffective whistleblower process."
• The Coast Guard accuses OceanGate of failing to properly investigate and address "known hull anomalies" following a 2022 expedition to the Titanic.

What they're saying: "This marine casualty and the loss of five lives was preventable," said Jason Neubauer, chair of the Coast Guard's Marine Board of Investigation, in a statement accompanying the report.

• "The two-year investigation has identified multiple contributing factors that led to this tragedy, providing valuable lessons learned to prevent a future occurrence."

Of note: The report includes 17 safety recommendations that the Coast Guard says are "aimed at strengthening oversight of submersible operations, improving coordination among federal agencies and closing gaps in international maritime policy."
