The Coast Guard said in a press release that four missing crew members are missing.
Six crew members were injured, Nueces County Judge Barbara Canales said in a statement. Four were taken to hospitals by ambulance and two more were flown to hospital by the Coast Guard.
According to Canales, the explosion occurred around 8 a.m. in an area where 18 people were working.
“The current focus must be on containing the fire, considering everyone involved, locating and caring for the injured and securing the scene by securing ship movement, cargo transfer and pipeline operations,” Canales’ statement said .
Canales said the fire has been contained and praised the work of the Corpus Christi Fire Department and the Refinery Terminal Fire Company.
The inner harbor of the Harbor Bridge within the ship canal is closed.
The National Transportation Safety Board said it would investigate the incident.
