After a two-year probe, the US Coast Guard concluded that the submersible's design and safety procedures were inadequate. Investigators also noted a "toxic workplace culture" and "intimidation tactics."

The US Coast Guard on Tuesday released a 300-page report after investigating the Titan submersible implosion that killed five people in 2023.

The disappearance of the Titan submersible, which was on an expedition to the ruins of the Titanic, had led to a search that grabbed worldwide attention. 

What did the Coast Guard conclude?

The Coast Guard blamed the disaster on the sub owner, OceanGate, a private company based in Washington state whose head was among the five on board. 

It said the implosion was "preventable" and cited OceanGate's "failure to follow established engineering protocols for safety, testing, and maintenance" as the "primary causal factor" for the disaster.

The report also criticized the sub's design. The Coast Guard reported that the tour operator's former director of engineering had said the first hull used on the Titan submersible was akin to a "high school project."

According to the report, OceanGate also had a "toxic workplace culture" that dissuaded employees from expressing safety concerns.

Investigators alleged that OceanGate had for years "leveraged intimidation tactics... and the company's favorable reputation to evade regulatory scrutiny."

"By strategically creating and exploiting regulatory confusion and oversight challenges, OceanGate was ultimately able to operate TITAN completely outside of the established deep-sea protocols," the report found.
