The National Transportation Safety Board (NTSB) investigator in charge, Marcel Muise, has disclosed a detailed timeline of events leading up to the recent bridge collision based on data retrieved from the voyage data recorder (VDR).
At approximately 12:39 a.m. ET, the ship departed from Seagirt Marine Terminal and by 1:07 a.m., it had entered the Fort McHenry Channel. At 01:24:59, numerous audible alarms were recorded on the ship's bridge audio, coinciding with the cessation of VDR sensor data recording. However, the VDR audio continued to record using a redundant power source.
