An oil spill is a disaster – environmentally, commercially and in PR terms, not to mention the significant danger they can put offshore crew in. BP’s Deepwater Horizon in the Mexican Gulf in 2010, believed to be the worst ever recorded, spilt 210 million gallons of oil into the region over a period of several months. In more recent months, a spill of crude oil off the coast of Brazil has impacted thousands of miles of the country’s north-eastern coastline.
