Prestige Oil Spill
By 2002, the Prestige oil tanker had 26 years of transport work as an oil tanker, but while carrying 77,000 metric tons of oil, the rundown tanker encountered a terrible storm off the coast of Spain. Then the ship started taking on water which caused the engines to stall.
Left with no other choice, the crew had to abandon ship while oil from the cargo they had been hauling started to spill into the ocean. Several days later, the ship was brought into the Spanish harbor, but the cleanup, legal costs and ecological damage was in the range of $6.9 billion.
