Crude Oil Spill

ABSTRACT A simulated Arctic crude oil spill was investigated by monitoring physical and chemical changes in a laboratory spill of Guanipa (Venezuelan) crude. The spill consisted of one gallon of crude on 100 gallons of synthetic seawater contained in a fiberglass tank fitted with a wave generator and a controlled radiation system, all located in an environmental chamber held at 2°C. Changes in oil composition were monitored using a gas liquid Chromatograph. Evaporation removed the largest quantity of material from the spill, the rate varying directly with the exposure time to solar radiation. Solution or sinking removed only minimal quantities of oil although the influence of these factors increased with time. The most notable physical change was the rapid formation of stable emulsions. These emulsions formed discrete lumps commonly referred to as “tarballs.” The formation of tarballs occurred within a few days after the spill and they remained stable over the four-month duration of the experiment. Their formation drastically reduced weathering effects by removing the bulk of the oil from contact with the air/seawater interface. It was concluded that a crude oil spill in the Arctic could contribute significantly to tarball pollution of northern oceans. Tarball formation is not limited, therefore, to warm waters and occurs independently of weathering processes. It would appear that tarball formation depends more on the chemical composition of the oil and the rate of formation depends upon the available wave mixing energy. The ultimate fate of oil spilled in Arctic regions could be in the form of persistent tarballs.

ABSTRACT In situ burning (ISB) aided by herding agents is a promising tool for oil spill response in Arctic waters. An advantageous aspect of the herder mediated ISB approach is that the application of herders as well as the subsequent ignition of the slick could potentially be carried out from aerial platforms. This could obviate the need for personnel to conduct operations on the surface near the burn, as well as reduce the response time required to mobilize the spill response equipment, especially in challenging Arctic conditions. In the last decade, several laboratory and field-scale tests have been conducted to prove the efficacy of herder-assisted ISB operations, sometimes achieving burn efficiencies greater than 90 %. However, there have been no field tests of aerial herder application followed by ignition. This paper presents results from a series of field experiments performed in a custom-built test basin 50 km northeast of Fairbanks, Alaska, in April 2015. A helicopter was employed to first apply herding agents (Siltech OP-40 or ThickSlick 6535) to Alaska North Slope crude oil slicks in simulated drift ice conditions, and then ignite the herded slicks using a Heli-torch. Two of five test burns yielded measurable outcomes, resulting in 70% - 85% removal of the test oil as it was drifting freely. Three of five test burns did not yield reliably measurable results, as wind action at the site prevented an accurate measurement of free-drifting burn efficiency. An unmanned aircraft, carrying prototypical payloads for herder spraying and in situ burn ignition was also tested. This is the first time successful aerial application of herders for ISB in the Arctic or elsewhere has been accomplished, and furthers the development of better tools for oil spill response in Arctic waters and beyond.

Crude Oil Spill

ABSTRACT This article examines the potential for benzene exposure during crude oil spill response. Literature review found that under normal conditions benzene is lost from an oil slick within 40 minutes to 8 hours. A correlation between benzene and API gravity is presented graphically. This information was used to develop worst-case scenarios. Results of a preliminary field investigation indicate that benzene overexposure may be possible during “ideal adverse” conditions. Four generic crude oil spills are described along with rationale for the suggested level of self protection.

Crude Oil Spill

ABSTRACT On July 16, 2000, a crude oil spill occurred at the PETROBRAS refinery Refinaria Presidente Getúlio Vargas-REPAR, located in Araucária, PR, Brazil. A significant quantity of oil was retained within an area known as Ponto 0, between the spill site and Rio Barigüi, contaminating the hanks of a small stream (Arroio Saldanha), the soil adjacent to the stream, and the soil of four small wetlands, over a distance of 2 km. This paper presents an overview of the remediation program for Ponto 0, and draws preliminary conclusions regarding the efficacy of different remediation technologies. The major remediation technologies are: 1) injection and recovery trenches for free-product recovery in the sector adjacent to the spill site; 2) in situ bioremediation along the floodplain of Arroio Saldanha; and 3) a treatment wetland near the discharge of Arroio Saldanha into Rio Barigüi. The trenches appear to have removed most of the free product from the sector adjacent to the spill site. There is preliminary evidence, based on soil monitoring data, for the efficacy of in situ bioremediation, but further data will be required before a firm conclusion can be drawn. The treatment wetland was successful in restoring wetland vegetation (an essential component of this technology), and appears to be capable of removing hydrocarbons from groundwater. Data of the groundwater monitoring program indicates a general decline in TPH concentrations, over the October 2000, August 2001 and April 2002 sampling campaigns. BTEX concentrations are generally below the method detection limit.

Oil Spill Response

Russian Arctic shelf - rich larder of the hydrocarbons, at the same time Northern Sea Route (NSR) - a strategically important route for transporting them. The extraction and the transportation of the hydrocarbons along the NSR requires the solution of a number of ecological and economic problems in the first place to ensure environmental and technogenic safety. For the solving of these problems on the continental shelf it is required a system of comprehensive measures: - the development of the regulatory framework for environmental support oil and gas projects; - the introduction and use of integrated methods for monitoring environmental conditions at the sites of technogenic loads on the shelf of the Arctic seas, including the use of drones; - creating different models for assessing the marginal stability of ecosystems to technogenic loads during production and transportation of hydrocarbons on the continental shelf based on systems of dynamic simulations; - the development and use of sensitivity maps of coastal areas of the Arctic seas during oil spill response; - accounting of the results of the analysis of the total environmental benefit in the development of oil spill response plans; - application of the principle of "zero" resetting, due to the high fishery valuation in Barents and Kara seas and the conservation of marine biological resources.
