Norwegian suppliers Framo, Maritime Partner, Norbit Aptomar, and NorLense have come together to create the Oil Spill Recovery Vessel Group to offer a complete oil-spill-response solution. Workers who were likely exposed to dispersants while cleaning up the 2010 Deepwater Horizon oil spill experienced a range of health symptoms including cough and wheeze and skin and eye irritation, according to scientists at the National Institutes of Health (NIH). The Pipeline and Hazardous Materials Safety Administration (PHMSA) is cracking down on smaller violations in the crude oil, petroleum, and hazardous liquid industries to combat a slow rise in the number of pipeline accidents. Natural source zone depletion (NSZD) is the new technical term for naturally occurring biodegradation processes that reduce petroleum, nonaqueous-phase liquids (NAPL) from the subsurface. The appeals court ruled that, while regrettable, the fact that the spill occurred does not mean that ExxonMobil violated pipeline integrity regulations for risk assessment.
