The vessel is the Defiant, a 265‑foot barge that was being towed toward the Port of San Juan from St. Thomas, U.S. Virgin Islands, just before the grounding. The cause of the grounding is under investigation, the Coast Guard said.
The Coast Guard is deploying its services and the Emergency Response Team to handle the response. ‘We urge the public to stay away from the area to allow response agencies to access and work at the site,’ the federal agency said.
