Petrotrin oil spill
The Petrotrin oil spill was a series of oil spills that occurred on the island of Trinidad and Tobago.
In total eleven oil spills occurred between 17 December 2013 and 29 December 2013. The first spill began on 17 December at 4:45 a.m. when the sea line No 10, operated by the Trinidad's national oil company Petrotrin, ruptured at the bottom of the Gulf of Paria near the company's Pointe-a-Pierre refinery. It was initially reported as a single oil spill near the southwestern town of La Brea but by the end of the month, ten more oil spills were confirmed.〔 It is the largest oil spill in the history of Trinidad and Tobago.
Petrotrin has been facing a lot of scrutiny since the spill due to a report that revealed the pipeline that exploded may not have been inspected in over seventeen years. The company was subsequently fined $20 million by the country’s Environment Management Authority. Petrotrin has taken responsibility for nine out of the eleven spills and blaming the other two on saboteurs.
== Clean-up ==
To clean-up the oil spill Petrotrin has opted to use the Corexit 9500 dispersant that was employed BP in the 2010 Deepwater Horizon oil spill. The purpose of oil dispersants is to accelerate the process of degrading oil. Oil that is spilled into a body of water will eventually break down naturally but it is a long process. The way that this dispersant functions is by breaking down oil into tiny droplets that are faster for nature to degrade.〔(【引用サイトリンク】title=YouTube - The Use of Oil Dispersants )〕 This allows two liquids that do not go well together, such as oil and water, to be able to mix. The use of this dispersant has proved to be a controversial decision because in a recent story conducted in 2012, scientists discovered that Corexit actually increases the toxicity of oil and is detrimental to the livelihood of the marine animals.〔(【引用サイトリンク】title=GT | News Center :: Gulf of Mexico Clean-Up Makes 2010 Spill 52-Times More Toxic )〕
