The Xingang Port oil spill is a spill that occurred in July 2010 caused by a rupture and subsequent explosion of two crude oil pipelines that run to an oil storage depot of the China National Petroleum Corporation in Xingang Harbour, Dalian, Liaoning Province, China. The 1,500 tonnes of oil spilled from the pipes created a 180 km2 (69 sq mi) slick in the Yellow Sea that grew to 430 km2 (170 sq mi) within a week. [3] [4] [5] By July 21, the spill had spread to 946 km2 (365 sq mi), and stretched as far as 90 km (56 mi) along the coast. [6]

The spill occurred after a process to desulfurize oil in a pipeline at the port began, triggering a fire which subsequently burned for 15 hours. The fire burned from oil that was released from a filled storage tank with a 90,000 ton capacity that collapsed as a result of the fire. Oil from other nearby tanks was, according to a Greenpeace report released several weeks after the incident, intentionally released to prevent the fire from expanding towards a tank containing dimethylbenzene, a flammable chemical. [2] [7]

Containment and cover-up allegations

Although Chinese government officials reported that as little as 1,500 tonnes of oil spilled, [2] a former University of Alaska marine conservation specialist, Rick Steiner, estimates the spill to have a much higher total, with somewhere in the range of 60,000 to 90,000 tons (18.47 to 27.70 million gallons) of oil spilled into the Yellow Sea. He said that "[i]t's enormous. That's at least as large as the official estimate of the Exxon Valdez disaster." [8] [9] However, a government spokesperson for Dalian refuted this estimate, and referred to a panel of experts assessing the spill's size and environmental effect saying that "[w]e will know w[h]ether it's smaller or bigger than 60,000 tons based on the conclusion made by the panel".[ citation needed ]

According to leaks on Weibo, the accident may have begun as early as June, 10. However, because the government never formally acknowledged the accident took place, as well as threatened informed citizens to delete their posts, the true nature of the accident was not clear to the public. No assessment on the effect on wildlife was ever carried out.

The ensuing fire burned for 15 hours and one firefighter drowned after being swept overboard into the water. There was extensive damage to local wildlife areas, aquaculture, and beaches were closed following the spill and conflagration which appeared to have been caused by the injection of a highly oxidizing sulfur reducing agent into a pipeline. [2]

On 26 July 2010, the Chinese local government announced the spill had been contained and that the spill had failed to reach open waters. [1] Cleanup efforts continued two weeks after the original explosion began, with operations to remove the oil performed at night when the oil is most viscous. [10]

The cleanup effort largely used low-tech methods, including containment booms and straw mats to absorb the oil, as well as a fleet of fishermen manually scooping oil out of the water and transferring it to barrels for storage and eventual disposal. Additionally, limited amounts of chemical dispersants were used, as well as a material to increase biodegradation of oil. [7]

Reaction

After the incident the Chinese government announced that safety standards would be tightened up at ports. [11]

Impact

The oil spill affected several aspects of the area's economy. Tourism was affected after oil began washing ashore on beaches, some of which were closed after the spill; according to Greenpeace, additional oil washing ashore was a possibility that remained for the rest of the summer. [7] The oil severely affected fishing industry near Dalian, especially offshore shellfish farms, many of which were contaminated by the oil, either killing the fish or rendering them unfit for consumption. The economic loss was estimated to be as high as tens of million US dollars. [7] Environmental damage was also serious as a result of the spill; the majority of wildlife inhabiting the area was exposed to oil, which led to the deaths of some, while others were expected to display longer-term effects. [7]

Lu Guang's pictures of the oil spill and the subsequent funeral of firefighter Zhang Liang were awarded a third prize in the category "Spot News" in the 2011 World Press Photo contest. [12] [13] [14]

Aftermath

The non-fiction bookThe Deepest Water Is Tears (最深的水是泪水) authored by Bao'erji Yuanye was based on the incident, and then adapted as the film The Bravest . [15]

The Exxon Valdez oil spill occurred in Prince William Sound, Alaska, on March 24, 1989. Exxon Valdez, an oil supertanker owned by Exxon Shipping Company bound for Long Beach, California struck Prince William Sound's Bligh Reef, 1.5 mi (2.4 km) west of Tatitlek, Alaska at 12:04 a.m. and spilled 10.8 million US gallons (257,000 bbl) of crude oil over the next few days.

Oil spill Release of petroleum into the environment

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land. Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products and their by-products, heavier fuels used by large ships such as bunker fuel, or the spill of any oily refuse or waste oil.

<i>Exxon Valdez</i> Oil tanker

Oriental Nicety, formerly Exxon Valdez, Exxon Mediterranean, SeaRiver Mediterranean, S/R Mediterranean, Mediterranean, and Dong Fang Ocean, was an oil tanker that gained notoriety after running aground in Prince William Sound, spilling its cargo of crude oil into the sea. On March 24, 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.

<span class="mw-page-title-main">Kalamazoo River oil spill</span>

The Kalamazoo River oil spill occurred in July 2010 when a pipeline operated by Enbridge burst and flowed into Talmadge Creek, a tributary of the Kalamazoo River. A 6-foot (1.8 m) break in the pipeline resulted in one of the largest inland oil spills in U.S. history. The pipeline carries diluted bitumen (dilbit), a heavy crude oil from Canada's Athabasca oil sands to the United States. Cleanup took five years. Following the spill, the volatile hydrocarbon diluents evaporated, leaving the heavier bitumen to sink in the water column. Thirty-five miles (56 km) of the Kalamazoo River were closed for clean-up until June 2012, when portions of the river were re-opened. On March 14, 2013, the Environmental Protection Agency (EPA) ordered Enbridge to return to dredge portions of the river to remove submerged oil and oil-contaminated sediment.

Energy accidents

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.

The MV Wakashio oil spill occurred after the Japanese bulk carrier Wakashio ran aground on a coral reef on 25 July 2020 at around 16:00 UTC. The ship began to leak fuel oil in the following weeks, and broke apart in mid August. Although much of the oil on board Wakashio was pumped out before she broke in half, an estimated 1,000 tonnes of oil spilled into the ocean in what was called by some scientists the worst environmental disaster ever in Mauritius. Two weeks after the incident, the Mauritian government declared the incident a national emergency.

The Amazon Venture oil spill occurred at the port of Savannah on the Savannah River in the U.S. state of Georgia. The spill, which occurred from December 4 to 6, 1986, was caused by three defective valves in the piping system of the oil tanker MV Amazon Venture, which leaked approximately 500,000 US gallons of fuel oil into the river.
