El Faro Pinger Search Turns Up Empty
A U.S. Navy tug was unable to detect any pings from the sunken El Faro cargo ship off the Bahamas and the search will now shift to using side-scan sonar, the U.S. National Transportation Safety Board said in its latest update on its investigation into the ships sinking.
The USNS Apache arrived at the last known position of the El Faro on October 23 and began searching for the vessel with a Towed Pinger Locator (TPL). The search area consists of a 10 nautical mile by 15 nautical mile area, in which the USNS Apache towed the TPL on 5 search lines across the search area in order to detect the acoustic signal associated with the El Faros pinger, the NTSB said.
The USNS Apache concluded the first phase of the pinger locator search on October 26 with negative results, the NTSB said. The TPLs ability to detect the El Faros pinger may be effected by the orientation of the vessel as it lays on the sea floor or the current condition and functionality of the El Faros pinger, according to the NTSB.
The second phase of the search began on October 27 using the Orion side-scan sonar system. The second phase will be conducted over the same search area and will consist of 13 search tracks taking approximately 14 days to complete. The side scan sonar system will be used to locate the El Faro, and if found, create an image of the vessel.
