Design of a flexible containment system for deep ocean oil spills
… roll, pitch and yaw. The pen diameter allows oil to separate from the water; a skimmer weir in the pen collects almost pure oil and pumps it to a tanker. An air can at the shroud top provides pre-tension that restrains lateral deflections due to a uniform current, and helps reduce the collapse …

Risk, Oil Spills, and Governance: Can Organizational Theory Help Us Understand the 2010 Deepwater Horizon Oil Spill?
<p>The 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico awakened communities to the increased risk of large-scale damage along their coastlines presented by new technology in deep water drilling. Normal accident theory and high reliability theory offer a framework through which to view the …

An Evaluation of the Effects of Marine Oil-spills, Remediation Strategies, and Shipwrecks on Microbial Community Structure and Succession
The evaluation of how Bacteria respond to oil-contamination, and the application of dispersants and biosurfactants, in North Sea seawater microcosms is the focus of Chapter Two. Analysis revealed that dispersants and biosurfactants, which significantly reduced the interfacial tension between oil …

Oil spills in cold climates with special reference to the transportation and exploration of hydrocarbons in the Kara Sea
Oil spilled in ice infested waters have frequently been under investigation through the last twenty years. This has been induced by the prospects of large oil reserves offshore both in the American and Russian Arctic. Two oil spill scenarios considering the oil exploration in the Kara Sea have been …

The Vulnerability of the Coast of Liberia to Marine Oil Spills: Implications for Biodiversity and Renewable Natural Resource Utilization
… African coastline has become a "hotspot" for oil production, and 17 oil exploration blocks have been designated off the Liberian coast. Liberia's 579 km coastal zone supports almost 60% of the country's human population and is endowed with natural resources of both biological and socioeconomic …

Liability for pollution damage from offshore oil spills: The CLC and fund conventions, the EU's Environmental Liability Directive and their implications for New Zealand law
… penalties and damages to compensate for all oil pollution claims. The recent Deepwater Horizon disaster has had global repercussions for operators and regulators, but has sparked little discussion of legal liability issues in the New Zealand context. New Zealand’s offshore petroleum liability …

Diagnostic techniques for detecting exposure and anemia in birds exposed to crude oil
Oil spills have long been recognized as a significant threat to wildlife. Historically, mortality estimates have served as the basis for assessing impact to natural resources. However, these mortality estimates alone neglect the more wide-spread impact of oil spills on wildlife including birds, …
