The US releases report on the accident investigation of the "Titan" deep-sea submersible.

The U.S. Coast Guard released the investigation report on the explosion accident of the deep-sea submersible "Titan" in June 2023. The report concluded that the main cause of the accident was the deficiencies in the design, certification, maintenance, and inspection processes of the "Titan" by the Ocean Gateway Exploration Company. This over 300-page investigation report outlines the key findings of the accident, the main causes of the accident, and other factors. The accident investigation committee found that abnormalities in the hull of the "Titan" had been observed after a deep-sea exploration operation in 2022, but the Ocean Gateway Exploration Company failed to conduct appropriate investigations and resolve the issue.
