At least two people have been hospitalized after a fire broke out on on a Shell platform in the Gulf of Mexico early Wednesday morning. The fire occurred on the Enchilada platform about 112 miles south of Vermilion Bay. 

The fire "has been reduced to a small flame coming out of a pipe in the platform," according to a U.S. Coast Guard news release, and a light sheen has been reported north of the Enchilada. The Coast Guard received an initial report of the fire at 1:20 a.m.

A 54-year-old man and a 29-year-old man suffered concussions and were airlifted to University of Texas Medical branch in Galveston, the release states. The older man also suffered flash burns, and the younger man had a sprained wrist. Coast Guard spokeswoman Lexi Preston said around noon Wednesday she could not comment on their conditions. 

The two injured workers were among 46 crew members evacuated by lifeboat to a nearby platform called Salsa. 

Shell said in a statement the fire resulted from an "operational incident," and that it had identified the source. Both the Enchilada and Salsa platforms were safely shut down, according to Shell, which added that it will investigate the cause. 

"No harm to people or the environment is ever acceptable and Shell deeply regrets that this incident occurred," the statement says. 

A Shell spokeswoman did not answer questions concerning any previous problems with the Enchilada, nor what specific actions the company will take to investigate the cause.
