The NTSB's Office of Marine Safety released four investigation reports between October-December 2022. They are:

​The NTSB's Office of Marine Safety (OMS) investigates marine casualties to determine the probable cause of each casualty and identify safety recommendations that will prevent similar events in the future.

Investigated casualties include those classified by the Coast Guard as major marine casualties in U.S. territorial waters or involving U.S.-flagged vessels worldwide, and casualties involving both US public (government) and nonpublic vessels. In addition, the office investigates select catastrophic marine casualties, as well as those of a recurring nature. (Learn more about the NTSB's OMS' roles and responsibilities.)
