U.S. Coast Guard provides Titan submersible MBI update

WASHINGTON – The U.S. Coast Guard Marine Board of Investigation (MBI) continues to actively investigate the factors that led to the tragic loss of the Titan submersible on June 18, 2023. 

The U.S. Coast Guard’s investigation remains active but will take longer than initially projected to complete. 

“The investigation into the implosion of the Titan submersible is a complex and ongoing effort,” said MBI Chair Jason Neubauer. “We are working closely with our domestic and international partners to ensure a comprehensive understanding of the incident.” 

Several factors have extended the original 12-month timeline for the investigation. These include the need to contract two salvage missions to secure vital evidence and the extensive forensic testing required, which has led to necessary delays. 

The MBI continues to coordinate with multiple investigative agencies that have concurrent jurisdiction or a substantial interest in the marine casualty.  

“We’re grateful for the international and interagency cooperation which has been vital in recovering, preserving and forensically testing evidence from a remote offshore region and extreme depth,” Neubauer said. “The MBI is committed to ensuring that we fully understand the factors that led to this tragedy in order to prevent similar occurrences in the future.” 

As the one-year anniversary date approaches, the MBI extends its deepest condolences to the families and friends of the five individuals who lost their lives during the incident. 

The MBI currently intends to hold a public hearing session by the end of the year, with specific details to be announced at least 60 days in advance.
