The Exxon Valdez was a single-hull crude oil tanker operated by Exxon Shipping Company, most famous for its 1989 grounding event that triggered one of the most high-profile and environmentally devastating manmade oil spills in United States history, located in the remote, ecologically productive waters of Alaska's Prince William Sound.

Key moments

1989-03-24The tanker struck Bligh Reef shortly after departing the Port of Valdez, rupturing its hull and releasing roughly 11 million gallons of unprocessed North Slope crude oil, which eventually spread to contaminate more than 2,000 kilometers of Alaskan shoreline.
1990U.S. federal regulators passed the Oil Pollution Act of 1990 directly in response to the disaster, mandating phased-in double-hull requirements for oil tankers operating in U.S. waters, standardized spill response plans, and expanded corporate liability rules for spill damages.
2007NOAA published survey results confirming an estimated 25,000+ gallons of toxic residual crude remained trapped in Prince William Sound beach sediment, with measurable chronic ecological harm still affecting local wildlife populations nearly 20 years post-spill.

Unmatched regulatory ripple effect

While it is not the largest oil spill recorded by volume, the Exxon Valdez disaster had disproportionate global policy impact due to widespread public anger at the slow, disorganized initial cleanup response and the location of the spill in a previously pristine, iconic wilderness area. Its regulatory reforms were adopted by dozens of other countries to improve maritime oil transport safety for decades afterward.

Permanent disruption to local coastal communities

The spill immediately collapsed Prince William Sound's lucrative wild salmon and Pacific herring fisheries that thousands of Indigenous Alaskan and local fishing families relied on for intergenerational livelihoods. Many of these fisheries never rebounded to pre-1989 levels, permanently reshaping the regional economic and cultural fabric of the area.

Legacy for modern fossil fuel oversight

Environmental advocacy groups and coastal regulators continue to cite the Exxon Valdez incident as a core cautionary case study when evaluating proposals for new coastal oil drilling projects, new cross-regional oil pipelines, and relaxed maritime safety rules for fossil fuel transport, making its impact still relevant more than 35 years after the grounding.

The tanker was over 301 meters long, 51 meters wide, and 26 meters deep (987 ft x 166 ft x 88 ft), with a deadweight of 214,861 long tons and a full-load displacement of 240,291 long tons. The ship was able to transport up to 235000 m3 at a sustained speed of 30 kph, powered by a 23.60 MW (31,650 shp) diesel engine. Its hull design was of the single-hull type, constructed by National Steel and Shipbuilding Company in San Diego, California. It was a relatively new tanker at the time of the spill, having been delivered to Exxon on 16 December 1986.

Incident and accidents

Oil spill

At the time of the spill, Exxon Valdez was employed to transport crude oil from the Alyeska consortium's pipeline terminal in Valdez, Alaska, to the lower 48 states of the United States. At the time it ran aground, the vessel was carrying about 201000 m3 of oil. After the spill, the vessel was towed to San Diego arriving on 10 June 1989, and repairs went underway on 30 June 1989. Approximately 1,600 tons of steel were removed and replaced that July, totaling US$30 million of repairs to the tanker. Its single-hull design remained unaltered.

The Exxon Valdez spill occurred under President George H. W. Bush, whose Environmental Protection Agency Administrator, William K. Reilly, reportedly played a significant role in mobilizing presidential support for action to contain and clean up the spill.[8]

Litigation

Litigation was filed on behalf of 38,000 litigants. In 1994, a jury awarded plaintiffs US$287 million in compensatory damages and US$5 billion in punitive damages. Exxon appealed and the Ninth Circuit Court reduced the punitive damages to US$2.5 billion.
