Investigators uncover 26 hours of data on El Faro voyage recorder
WASHINGTON Aug. 24, 2016 The National Transportation Safety Board announced Wednesday the convening of a voyage data recorder group, Monday, to develop a detailed transcript of the sounds and discernible words captured on the El Faro’s bridge audio, following the audition of the ship’s VDR.
The voyage data recorder from El Faro, a US flagged cargo ship that sank during Hurricane Joaquin in October 2015, was successfully recovered from the ocean floor Aug. 8, 2016, and transported to the NTSB’s laboratory here Aug. 12. Information from the El Faro’s VDR was successfully recovered Aug. 15.
About 26 hours of information was recovered from the VDR, including bridge audio, weather data and navigational data. Investigators examined the VDR, found it to be in good condition, and downloaded the memory module data in accordance with the manufacturer’s recommended procedures.
Numerous events leading up to the loss of the El Faro are heard on the VDR’s audio, recorded from microphones on the ship’s bridge. The quality of the recording is degraded because of high levels of background noise. There are times during the recording when the content of crew discussion is difficult to determine, at other times the content can be determined using audio filtering.
The recording began about 5:37 a.m., Sept. 30, 2015 – about 8 hours after the El Faro departed Jacksonville, Florida, with the ship about 150 nautical miles southeast of the city. The bridge audio from the morning of Oct. 1, captured the master and crew discussing their actions regarding flooding and the vessel’s list. The vessel’s loss of propulsion was mentioned on the bridge audio about 6:13 a.m. Also captured was the master speaking on the telephone, notifying shoreside personnel of the vessel’s critical situation, and preparing to abandon ship if necessary. The master ordered abandon ship and sounded the alarm about 7:30 a.m., Oct. 1, 2015. The recording ended about 10 minutes later when the El Faro was about 39 nautical miles northeast of Crooked Island, Bahamas. These times are preliminary and subject to change and final validation by the voyage data recorder group.
The VDR group’s technical experts will continue reviewing the entire recording, including crew discussions regarding the weather situation and the operation and condition of the ship.
Families of the El Faro’s crew were briefed about the results of the audition Wednesday prior to the NTSB’s public release of the characterization of the audition.
It remains unknown how long it will take to develop the final transcript of the El Faro’s VDR. The length of the recording and high levels of background noise will make transcript development a time consuming process. An update will be provided when warranted.
