A double-hulled tanker refers to an oil tanker which has a double hull. They reduce the likelihood of leaks occurring compared to single-hulled tankers, and their ability to prevent or reduce oil spills led to double hulls being standardized for oil tankers and other types of ships including by the International Convention for the Prevention of Pollution from Ships or MARPOL Convention. After the Exxon Valdez oil spill disaster in Alaska in 1989, the US government required all new oil tankers built for use between US ports to be equipped with a full double hull.
The Exxon Valdez oil spill was a major environmental disaster that occurred in Alaska's Prince William Sound on March 24, 1989. The spill occurred when Exxon Valdez, an oil supertanker owned by Exxon Shipping Company, bound for Long Beach, California, struck Prince William Sound's Bligh Reef, 6 mi (9.7 km) west of Tatitlek, Alaska at 12:04 a.m. The tanker spilled more than 10 million US gallons (240,000 bbl) of crude oil over the next few days.
Valdez is a city in the Chugach Census Area in the U.S. state of Alaska. According to the 2020 US Census, the population of the city is 3,985, up from 3,976 in 2010. It is the third most populated city in Alaska's Unorganized Borough.
Exxon Valdez was an oil tanker that gained notoriety after running aground in Prince William Sound, spilling her cargo of crude oil into the sea. On 24 March 1989, while owned by the former Exxon Shipping Company, captained by Joseph Hazelwood and First Mate James Kunkel, and bound for Long Beach, California, the vessel ran aground on the Bligh Reef, resulting in the second largest oil spill in United States history. The size of the spill is estimated to have been 40,900 to 120,000 m3. In 1989, the Exxon Valdez oil spill was listed as the 54th-largest spill in history.
The Alyeska consortium refers to the major oil companies that own and operate the Trans-Alaska Pipeline System (TAPS) through the Alyeska Pipeline Service Company.
An environmental disaster or ecological disaster is defined as a catastrophic event regarding the natural environment that is due to human activity. This point distinguishes environmental disasters from other disturbances such as natural disasters and intentional acts of war such as nuclear bombings.
The Oil Pollution Act of 1990 (OPA) was passed by the 101st United States Congress and signed by President George H. W. Bush. It works to avoid oil spills from vessels and facilities by enforcing removal of spilled oil and assigning liability for the cost of cleanup and damage; requires specific operating procedures; defines responsible parties and financial liability; implements processes for measuring damages; specifies damages for which violators are liable; and establishes a fund for damages, cleanup, and removal costs. This statute has resulted in instrumental changes in the oil production, transportation, and distribution industries.
Joseph Jeffrey Hazelwood was an American sailor. He was the captain of Exxon Valdez during her 1989 oil spill. He was accused of being intoxicated which contributed to the disaster, but was cleared of this charge at his 1990 trial after witnesses testified that he was sober around the time of the accident. Hazelwood was convicted of a lesser charge, negligent discharge of oil, fined $50,000, and sentenced to 1,000 hours of community service.
The Valdez Blockade was a 1993 protest by Cordova fishermen who blockaded the Valdez Narrows in an attempt to obtain funding for research and restoration efforts relating to decreasing yields of pink salmon and herring in Prince William Sound following the Exxon Valdez Oil Spill. The fishermen were dissatisfied with the Exxon Valdez Oil Spill Trustee’s Council’s refusal to fund research efforts into the spill's effects on the fish. The blockade lasted three days, from August 20 to August 22. The blockade ended when Secretary of the Interior, Bruce Babbitt, promised funding for salmon and herring research. Findings from these studies resulted in additional compensation from Exxon.
SeaRiver Maritime is a wholly owned subsidiary of ExxonMobil. The company was formed in the early 1990s by Exxon when it spun off its maritime operations into the new company following the Exxon Valdez oil spill in 1989.
The Prestige oil spill occurred off the coast of Galicia, Spain in November 2002, caused by the sinking of the 26-year-old, structurally deficient oil tanker MV Prestige, carrying 77,000 tonnes of heavy fuel oil. During a storm, it burst a tank on 13 November, and French, Spanish, and Portuguese governments refused to allow the ship to dock. The vessel subsequently sank on 19 November, about 210 kilometres (130 mi) from the coast of Galicia. It is estimated that it spilled 60,000 tonnes or a volume of 67,000 m3 (17.8 million US gal) of heavy fuel oil.
The 2010 Port Arthur oil spill was the result of a collision between two vessels in the Sabine-Neches Waterway at Port Arthur, Texas on January 23, 2010. The two vessels were the oil tanker Eagle Otome and a barge being pushed by the towboat Dixie Vengeance.
Odyssey, which previously went by the name Oriental Phoenix, was an oil tanker in operation from 1971 to November 10, 1988, when an explosion caused it to sink in the North Atlantic off the coast of Canada. The resulting spill remains one of the largest oil spills in world history. The tanker was 700 nautical miles off the coast of the Canadian province of Nova Scotia when it sank and released 132,157 tons of oil into the ocean, valued at some $86.7 million (2010). By way of comparison, four times as much oil was spilled by the Odyssey as from the much more famous Exxon Valdez.
Energy resources bring with them great social and economic promise, providing financial growth for communities and energy services for local economies. However, the infrastructure which delivers energy services can break down in an energy accident, sometimes causing considerable damage. Energy fatalities can occur, and with many systems deaths will happen often, even when the systems are working as intended.
International Bird Rescue is a nonprofit organization that rehabilitates injured aquatic birds, most notably seabirds affected by oil spills. Founded by Alice Berkner and members of the Ecology Action, including veterinarian James Michael Harris, D.V.M. in 1971 and based in Cordelia, California, the group has developed scientifically-based bird rehabilitation techniques and has led oiled wildlife rescue efforts in more than 200 oil spills worldwide, including the 1989 Exxon Valdez oil spill in Prince William Sound, Alaska, and the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, where International Bird Rescue co-managed oiled bird rehabilitation efforts in four states with Tri-State Bird Rescue and Research.
Riki Ott is a marine toxicologist and activist in Cordova, Alaska. Ott was frequently introduced as an "oil spill expert" in her many media appearances during the height of the 2010 BP Deepwater Horizon oil spill news coverage. After graduating with a doctorate in sedimentary toxicology from the University of Washington, Ott moved to Alaska and started a fishing business. When the Exxon Valdez oil spill disrupted the local fishing-based economy, she became an environmental activist. Since the spill, she has participated in legal and public relations disputes with the Exxon company.
The Prince William Sound Regional Citizens' Advisory Council is an independent non-profit organization based in Anchorage and Valdez, Alaska, whose mission is to promote the environmentally-safe operation of the Alyeska Pipeline's Valdez Marine Terminal and associated oil tankers, and to inform the public of those activities.
As the world's largest majority investor-owned oil and gas corporation, ExxonMobil has received significant amounts of controversy and criticism, mostly due to its activities which increase the speed of climate change and its denial of global warming.
Walter Bruce "Walt" Parker was an American civil servant, policy adviser, transportation adviser, academic and local politician. Parker's career focused on the development of natural resources, transportation and infrastructure in Alaska from the 1940s to the 2000s. In 1989, Alaska Governor Steve Cowper appointed Parker as the chairman of the Alaska Oil Spill Commission, which investigated the Exxon Valdez oil spill. He is credited with making important contributions to the fields of transportation, telecommunications, education, land use and urban planning within the state of Alaska. Parker was inducted into the Alaska Conservation Hall of Fame by the Alaska Conservation Foundation in 2002 for his contributions to state conservation.
Oil pollution toxicity to marine fish has been observed from oil spills such as the Exxon Valdez disaster, and from nonpoint sources, such as surface runoff, which is the largest source of oil pollution in marine waters.
