The US Coast Guard has suspended the search for a worker missing from an oil production platform in Louisiana’s Lake Pontchartrain, according to Reuters news agency.
The rig exploded and caught fire late on Sunday.
Missing is Timothy Morrison, 44, of Katy, Texas, the Coast Guard said in a statement.
Seven other workers were sent to hospital with injuries in the incident.
“The decision to suspend a search is never an easy one,” Commander Zac Ford said in the statement.
“We send our thoughts and prayers to the Morrison family and all those affected.”
Coast Guard rescue crews battled 4 foot to 5 foot (1.2 meter to 1.5 meter) waves during the search, and a helicopter joined them at daybreak after overnight efforts failed to locate Morrison, officials said at a briefing on Monday.
