subject: China's Reliance On Imported Oil, Marine Environmental Risk Reserves [print this page] HC plastic net News: Gulf of Mexico crude oil spill, let the whole world shocked. Offshore and marine ecological risks of oil transportation, and again let the world attention. To this end, the reporter interviewed several experts, asking them to comment on the incident.
Oil spill is known as the marine environment of the super-killer Vice President of China Environmental Science
Hui Cheng C: Gulf of Mexico, "Deep Horizon" oil platform leak explosion now has not been fully checked, oil leaks faster than the U.S. government initially expected, causing the disaster than the original expected to be much more serious, now the oil spill in U.S. history has turned into the worst oil pollution disaster. Oil forecast the economic loss caused by the disaster reached 140 billion dollars, the insurance company forecast at least 1.5 billion in compensation. However, the ecological damage is incalculable. Do not know how to assess the ecological damage the United States.
WWF China Representative Ouda Dream: The oil spill is known as the marine environment of super-killer. According to statistics, every year through various channels leaked into the sea of oil and petroleum products account for about 0.5% of world oil production, in which the pollution caused by oil tankers the most prominent victims. U.S. oil drilling platform, the oil spill occurred in the United States can be considered as a major ecological disaster in history, but mainly caused by human factors.
Large number of offshore oil, kept in the manufacture of "the biggest ecological disaster." March 2009, we WWF published a research report. Our March 23, 1989 crude oil spill incident in a sustained study found that 20 years is still not sufficient to eliminate a major oil spill aftermath, do not know this takes many years. In March 1989 of this incident is considered the worst in U.S. history, oil spill, two years after the disaster to the U.S. state of Alaska coast, still covered with vast quantities of oil. March 23, 1989 night, the Yikesenwa Valdez oil tanker ran aground, leaking 11 million gallons of crude oil, then a little bay on the flow or leak into the next beach. Tanker just left 20 001 1000 gallons of crude oil leak is not fully complete. Residual oil is any harm one can imagine. Immersed in water mixture to 25 cm deep underground, even in the February 6, 2009 to leak into the Prince William Sound, Alaska, Yili Luo Island. Disaster incident, the oil quickly spread throughout. While the crew was focused on removal of oil residues in action until the end of 1994, but then, experts incorrectly predicted: oil in a few years should automatically disappear. In contrast, oil has slowly spread throughout, also causing a serious impact. Mainly oil-covered coast to the isolated open. This piece of water has been swallowed residual and bacterial contamination of the oil.
Various causes of marine oil pollution incidents
Present, increasing offshore oil exploration activities, offshore oil transport is also increasingly active in the world have been frequent incidents of marine pollution, oil spills, marine ecology of the area has had serious effects. The United States also "create" many times. Pollution caused by marine oil spill incidents frequent a variety of reasons: First, offshore oil spills at sea shipping factors. Mainly ships and oil facilities of conflict, including the ship collided with the offshore oil facilities, ships or oil tankers and other ocean, marine facilities, oil spill caused by the collision. Such as the March 24, 1989 in the United States tanker ran aground in waters near Alaska, "Exxon? Waerdici" number, resulting in 34,000 tons of crude oil into the Prince William Sound. Second, the process of offshore oil rigs, or oil, or other reasons due to an explosion sank, resulting in huge oil spill. Norway's North Sea oil fields, such as sudden in 1977, an explosion, causing wells sunk the insurance facilities, and the Gulf of Mexico, "Deep Horizon" oil platform explosion belong to such incidents. The third is a result of natural marine oil spill incidents. Such as the 1974 Mississippi River near the mouth of two oil rigs subversion oil oil spill accident, the cause is due to hurricane-induced landslide, which led to subversion rigs, oil spills.
