On October 1, 2021, an oil spill deposited crude oil onto several Southern California beaches on the West Coast of the United States. While residents reported smelling fumes, a ship noticed an oil slick that evening and reported it to federal authorities. When oil from an underwater pipeline in the waters of coastal Orange County began washing ashore, officials in Huntington Beach closed the typically crowded beach in the evening of October 2. The U.S. Coast Guard estimated that spill covered of the ocean's surface as they monitored it several times daily from the air. Investigations found a pipeline connecting offshore oil platforms with the shore had been displaced by being dragged by a ship's anchor.
Commercial divers found the pipeline had been displaced by about with a split along the length of the pipe. Investigators suspect that two large container ships possibly dragged their anchors in this area during heavy winds on Jan. 25, 2021. An Orange County official compared the event to the 2015 Refugio oil spill in Santa Barbara County, which took months to clean up. Platform Elly pumps oil and gas to shore at the Port of Long Beach through this pipeline. The pipeline is operated by Beta Offshore, a Long Beach unit of Houston's Amplify Energy. The pipeline was repaired and returned to service in April 2023.
Background A consortium led by Royal Dutch Shell discovered the Beta field in 1976 in San Pedro Bay and built the platforms Elly and Ellen in 1980. The complex began producing in January 1981. In 1984, they added Eureka. Connected by pipelines, Ellen and Eureka have dozens of wells while Elly separates the water and natural gas from the crude oil. A , laid upon the ocean floor for , connects Elly with the shore. In 1999, a pipeline that carried oil, water and gas from the Eureka platform to Elly leaked about of oil into the ocean due to corrosion. The platforms were set in the separation zone between the northbound and southbound lanes for container ships and other vessels entering and exiting the ports of Los Angeles and Long Beach, two of the world's busiest ports. Maritime officials tried to stop construction of the platforms. The Coast Guard raised objections, preferring that no platforms be built in the area. In 2000, the shipping lanes were relocated about west of the platforms as the newer deep draft vessels required significant room to maneuver.
The platforms are in federal waters overseen by the U.S. Department of the Interior. Beta Offshore, a subsidiary of Amplify Energy and current owner, pays royalties to the government in exchange for the lease on federal property as do other oil and gas companies. As these wells were no longer producing as much oil, the company received a $20-million “end of life” royalty discount for two years starting in July 2016. When it planned to drill four new wells, they received another royalty discount in June 2020.
Detection and response
An alarm from a leak detection system sounded at 4:10 p.m. on October 1 and the operators shut down the pipeline. Believing that the system was providing false alarms for a leak at the platform, they began a series of restarting and stopping the flow of oil throughout the night. In the afternoon and evening of October 1, Huntington Beach and Newport Beach residents were already noticing a strong odor and called the police department to report the smell of oil fumes or hot roofing bitumen. Multiple calls concerning a possible spill north of the Huntington Beach Pier came in over a marine radio emergency channel from boats leaving the Pacific Airshow. The harbor patrol looked for the spill but found nothing on the water. In the evening, a foreign ship anchored off the coast reported a possible oil slick about west of Huntington Beach. A satellite image from the European Space Agency was reviewed by a National Oceanic and Atmospheric Administration analyst which confirmed a substance on the water which was most likely petroleum. The Marine Oil Spill Thickness (MOST) project also deployed Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) to assist by measuring the thickness of the oil spill from an aircraft. The National Response Center, staffed by United States Coast Guard officers and marine science technicians, is the sole federal point of contact for reporting all hazardous substances releases and oil spills. They forwarded the information to the Office of Spill Prevention and Response (OSPR), a division of the California Department of Fish and Wildlife charged with handling such emergencies. OSPR dispatched but encountered foggy conditions. The Coast Guard and Orange County Sheriff's Department flew out once the fog had lifted to the reported leak location to investigate. Control room operators on platform Elly shut down the pipeline at 6:01 a.m. on October 2 in response to a low-pressure alarm according to the Pipeline and Hazardous Materials Safety Administration after ignoring 83 alarms indicating the offshore pipeline was leaking for about 17 hours. They also failed to notify the Coast Guard until 9:07 a.m. The pipeline was suctioned at both ends to stop the flow of oil after it was shut down.
A full-scale mobilization effort was established with a Unified Command (ICS) which would eventually consist of the Coast Guard and the Office of Spill Prevention and Response with support from the cities of Long Beach, Newport Beach, Huntington Beach, the Orange County Sheriff's Department, and the county of San Diego together with the responsible party, Beta Offshore. The US Coast Guard estimated that spill covered of the ocean's surface as they monitored it several times daily from the air. Officials characterized it as isolated ribbons of oil, or patches of oil rather than a big blob. Wind, waves and tides all help determine the impact of an oil slick. Generally mild conditions kept the bulk of the oil offshore, which is much simpler for crews to contain and clean up. The initial mobilization included mechanical equipment called skimmers that collect the oil on the surface of the water. Barriers called booms were also set up in the open ocean to try to stop the oil from spreading. The ocean currents pushed the plumes of oil south without large amounts entering the surf zone and fouling the beaches. Rocky coves along the coast south of Newport Beach which would have been difficult to clean were mainly spared. Cleanup efforts can damage the animals and plants that live there. During the days, workers in hazmat gear scoured the beaches to find and remove tar balls and any traces of damage from the spill. More than 1,300 workers were cleaning the shoreline in much of Orange County by October 9.
Pipeline investigation Platform Elly pumps crude oil through a which connects offshore oil platforms with the Port of Long Beach. The pipeline operator, Beta Offshore, a Long Beach unit of Houston's Amplify Energy, found the pipeline was intact during an inspection in October 2020. The investigation after the spill found that the pipeline had been displaced, possibly by being dragged by a ship's anchor. The pipeline at this point was at a depth of about about offshore. Contract divers and remotely-operated vehicles found a section of the pipeline had been pulled like a bowstring so that it was about out of place at its widest point with a aligned with the length of the pipe. They also confirmed that the split in the pipeline was no longer leaking. Initial investigations were of ships anchored closest to the pipeline the week before the spill such as the which was boarded by the Coast Guard. The investigation continued with particular interest in ships that were waiting to get into port and anchored outside an assigned anchorage or too close to a pipeline that was marked on nautical charts. Further inspection found marine growth around the displaced section of the pipeline indicating that the anchor drag was not a recent event. They are looking for an initial anchor strike which deflected the pipeline and stripped away its concrete casing without fracturing the pipeline. The pipeline would have been more vulnerable to additional stresses added later by another incident or geological events. Investigators focused on a storm that brought strong winds to the area for two days in late January 2021. Data was reviewed that shows every vessel that has been near the pipeline since October 2020. Investigators typically examine logs kept by the ships’ captains, officers and engineers, voyage data recorders, and parts of the ship such as the anchor. The investigation is open to the possibilities that the initial impact caused the leak, that the line was hit by something else at a later date or that the line failed due to a preexisting problem. On October 16, the container ship MSC Danit was boarded by the Coast Guard and National Transportation Safety Board marine casualty investigators in the Port of Long Beach. The ship operator Mediterranean Shipping Company, the ship owner Dordellas Finance Corporation, and others were designated as parties of interest in the investigation. On November 18, the container ship Beijing was boarded by the Coast Guard and National Transportation Safety Board marine casualty investigators in the Port of Long Beach. The ship operator, V-Ships Greece Ltd., and the ship owner, Capetanissa of Liberia, were designated as parties of interest in the investigation.
Environmental effect It only took a few hours for the oil to be up on the beach due to the short distance and the persistent westward and southwestern wind. The crude oil, like all Southern California oils, was extremely heavy, dark, and dense which tends to be more toxic than the lighter oils. Officials in Huntington Beach closed the typically crowded beach in the evening of October 2. By the morning of October 3, oil had already entered Talbert Marsh and other wetland areas of Huntington Beach. Crews worked to keep as much oil as possible out of ecologically sensitive areas with sand berms and floating booms. Oil that has entered an estuary and marsh habit cannot be cleaned up without causing more damage. It will eventually be sequestered by the sediment where it will take decades to degrade. These wetlands were restored in 1991 after having been severely degraded. Crude oil entered of wetlands through an inlet to the ocean on a . The spill occurred right after nesting season and just before migratory birds come down so fewer birds were present than other seasons. Birds that gather in and around Huntington State Beach include gulls, willet, long-billed fletcher, Elegant terns and reddish egret. Forty-five birds were already dead when they arrived at the Oiled Wildlife Care Network. Exposure to oil weighs a bird down causing them to expend more energy to fly, float and maintain their body temperature. Instead of hunting for food on the water, they lie on the beach trying to stay warm. By October 12, wildlife officials had found 28 oil-covered birds which underwent a cleaning and rehabilitation program. A mixture of solvent, dish soap and warm water is used to remove the oil. Six of those birds died or were euthanized. Significant impacts can still occur to birds and marine life from the exposure that they get subtly through their diet or because of physical contact later on which might affect their physiology, their health and translate into a lower reproductive success.
