The examination of data from the voyage data recorder began on August 15, one week after the device was located at a depth of 15,000 feet and brought to the surface. NTSB recovered about 26 hours of information from the device, including bridge audio, navigational data, onboard radar images, route planning and wind data.
The investigation seeks to determine which factors contributed to the sinking, and will look for evidence of misconduct, inattention to duty, negligence, willful violation of the law by any licensed or certified person, as well as whether there is any evidence that Coast Guard personnel or any government employee contributed to the accident.
The 737-foot ship sank on October 1, 2015, less than 90 minutes after losing power. The ship was just east of the Bahamas as Hurricane Joaquin approached, and resulted in the loss of all 33 crewmembers.
