In his theory of a normal accident, Perrow considers the combination of interactive complexity and close ties as a measure of the possibility of a system causing disaster. Due to the intrinsic complexity and tight coupling of the system (Perrow, 1999), accidents caused by the convergence of these two attributes are inevitable and are considered "ordinary accidents". High degree of interconnectivity between system components, dependence on indirect information sources, unpredictable environment, or unintelligibility to the operator of the system indicates the complexity within the system (Pe rrow, 1999 ).
Do you remember the oil spill of BP? Do you know that the deepwater Horizon Bay in Mexico leaked more than 200 million gallons of crude oil in the early two months of 2010? The outflow was very bad, and respondents were well-known to "burn to the ground", a process that burns oil concentrating on the sea surface. The story began in 1995, the year when Waterworld was released. Mr. Costner did the water filtration of the brain. After all, this is a large part of the movie. It is easy to imagine that after spending 157 days on production of $ 235 million, Costner was forced to pay $ 25 million for water pollution solutions (Exxon Valdez's oil spill is a long- It caused concern). )
Regulation and BP oil leaked to Deepwater Horizon. The outflow of BP's "deep sea horizon" was the most serious accidental oil spill in US history. The original oil drilling equipment exploded on April 20, 2010, 11 people died and 17 people were injured. Nearly 5 million barrels of oil leaked into the Gulf of Mexico, causing serious environmental and economic losses, and further disasters, the three pillars of the Gulf Coast economy, fisheries, tourism, energy production - the total cost of economics and cleaning It collapsed seriously. Billions of dollars
