Members of the Coast Guard said they have suspended the search for a missing crewmember near Sabine Pass, Texas.
First-responders said approximately 2,823 square miles were covered over 48 hours with four aircraft and two vessels during the search.
Coast Guard members said they received the initial report Wednesday evening of a 27-year-old male crewmember who had fallen overboard from the tanker vessel Sagami while rigging an accommodation ladder.
The individual was last seen wearing an orange work flotation vest and coveralls with reflective tape.
"The Coast Guard completed an exhaustive search using all available search and rescue assets," said Petty Officer 1st Class John McKendrick, Sector Houston-Galveston command duty officer. "Cases like these are hard and our thoughts and prayers are with this mariner's family, friends and shipmates."
