A large-scale cleanup operation is underway in the Gulf of Mexico near Grand Isle, Louisiana after a crude oil spill linked to the Louisiana Offshore Oil Port (LOOP) prompted an extensive response from federal and state authorities.
The response is being coordinated by a Unified Command consisting of the United States Coast Guard, the Louisiana Oil Spill Coordinator’s Office (LOSCO), and LOOP. The joint operation began on February 27 after crude oil was detected near the offshore terminal a day earlier.
Officials said the spill occurred on February 26 following an offshore mechanical failure at the LOOP facility. According to the latest update issued on March 7, approximately 31,500 gallons (about 750 barrels) of crude oil were discharged into surrounding waters. Authorities confirmed that the source of the leak has been secured, preventing further release.
Cleanup teams have already recovered roughly 27,888 gallons (664 barrels) of oil from the water, while operations continue to contain and remove the remaining traces. The response effort has expanded significantly, with about 464 personnel and 60 vessels currently involved in the cleanup operation.
To prevent the oil from spreading, responders have deployed around 28,300 feet of protective and recovery boom in affected waters. Aerial surveillance missions using fixed-wing aircraft, helicopters and drones are also being conducted daily to track the movement of oil slicks and guide recovery operations.
Most of the recovered oil has been collected from open water, although smaller amounts have also been retrieved from nearby barrier islands along the Louisiana coast. Environmental monitoring teams are simultaneously assessing the potential impact on coastal ecosystems and wildlife.
The Louisiana Department of Wildlife and Fisheries and the United States Fish and Wildlife Service are monitoring affected bird populations and shoreline areas as part of the ongoing environmental assessment.
Maritime authorities have advised vessels to avoid the affected area and monitor VHF-FM Channel 16 for navigation advisories while the cleanup effort continues.
Situated roughly 18 miles offshore of Louisiana, LOOP is the only deepwater port in the United States capable of handling fully loaded very large crude carriers (VLCCs). The facility plays a key role in the country’s crude oil import, storage and distribution system.
The spill also comes at a time when the United States is expanding its offshore oil export infrastructure. In 2025, the United States Maritime Administration approved the development of the Texas GulfLink Deepwater Oil Port off the coast of Texas. The project, owned by Sentinel Midstream, will feature offshore single-point mooring buoys designed to load VLCCs directly at sea, strengthening the country’s crude export capacity.
Officials said response teams will continue cleanup and monitoring operations in the coming days as they work to recover the remaining oil and evaluate any longer-term environmental impacts.
