I have included some lists of where oil spills have occurred.
Some very large oil spills occurred during wars (Kuwait-Iraq War,
Iran-Iraq War, World War II), and these were intentional, so they
do not show up on lists of accidental oil spills.
Also, there are many different causes for oil spills. There are
accidents associated with tankers, barges, pipelines, refineries,
production platforms and drilling rigs occurring in many different
countries.
The list of oil spills differ. The list from 2009 does not
include the BP oil spill. Some lists do not include smaller oil
spills. The list from the tanker association includes spills from
the transportation of oil, not the exploration, production and
refining of crude oil. But all lists show that oil spills have
occurred in Asia, Africa, Europe, North America and South America.
The US has a long history of oil spills as the US is one of the
oldest countries producing and transporting crude oil.
