The properties of some organic materials in the removal of oil from water area were studied. It was shown that available materials as technical wool and sintepon can be used as effective sorbents for petroleum removal from water area. The sample mechanical wringing of these sorbents permits to return the part of adsorbed oil for its next use. The dependence of sorption properties (the adsorbed petroleum mass, specific oil adsorption, return of the oil and selectivity of petroleum removal) and petroleum removal from the number of absorption-release cycles was established. It was established that quantity of adsorbed oil decreases in other next step of removal but mass of oil returned increases in the process of mechanical wringing. The regeneration of these adsorbents by flushing in gasoline permits to obtained the initial properties in oil removal from water area. The sorption elements in the form of bags from linen with these materials were prepared. The dependence of the amount of oil removed by these sorption elements from the time of oil clearing of the water area process was determined and the optimal parameters of petroleum removal were established. It was shown that sorption elements on the base of these materials have adsorption capacity equal to 14-16 g of petroleum/g sorbent at selectivity of petroleum removal more than 70 % and oil recovery degree more than 80 % and the possibility their reusable use on oil spill response. The obtained positive results of oil removal from water area permit to propose in extreme cases of oil spills the available industrial products as jerseys, blankest, jackets etc. use successfully for petroleum spill response. The hydrophobization of these elements permits to improve their properties in oil removal from water area. As results of sorption elements modification the increase of adsorbed oil mass and specific petroleum removal at simultaneous increase of returned oil quantity for its next use and oil removal selectivity were established. It was established that synthesized sorption elements not inferior in properties known industrial sorbents for oil removal from water area.

ABSTRACT This paper examines explosion hazards while recovering spilled oil utilizing oil spill recovery barges. The risk of static accumulation and discharge is well understood after thorough investigations of several incidents in the 1970s and 1980s involving explosions on tank barges and vessels during petroleum cargo loading and unloading operations. However, those lessons learned only partially apply to oil spill recovery operations due to the differences in liquid properties, crew training, and additional tasks required during an oil spill response. While regulatory standards have been enacted for petroleum tankers and barges involved in commercial transportation of oil and other hazardous materials, the utility of these standards for oil spill response vessels has not been fully considered. Inverviews were conducted with marine transporters and response organizations to understand the wide range of operational risks and mitigation proceedures currently in use. This paper outlines the four basic conditions that must be present to create a static discharge-induced explosion during liquid cargo operations. A review of explosion casualty history was completed for cargo operations and compared to operations that create similar hazards during oil spill recovery operations. Specific processes that create additional risk of static-induced explosions during response operations were studied to review mitigation actions. Finally, recommendations for continued training are provided to help guide the spill response community when preparing for and responding to oil spills.

ABSTRACT The overall objective of the Mechanical Oil Recovery in Ice Infested Waters (MORICE) program is to improve the effectiveness of equipment and techniques for the mechanical recovery of oil spills in ice-infested waters. MORICE is a multi-national effort that has involved Norwegian, Canadian, American and German researchers. Results from previous laboratory, meso-scale phases have been summarized (Johannessen et al, 1996, 1998), (Jensen et al., 1999), (Jensen & Solsberg, 2000, 2001). In January 2002, the full-scale proof of concepts with two different internal recovery units were successfully tested and evaluated at Ohmsett – The National Oil Spill Response Test Facility located in Leonardo, New Jersey (Jensen & Mullin, 2002). Results of the Ohmsett tests are presented along with recommendations for developing a commercialized skimmer that will effectively operate in broken ice conditions.

Oil Spill Response

This paper presents the methodology, assumptions, and functionalities of an application developed during the realization of the project “South Baltic Oil Spill Response through Clean-up with Biogenic Oil Binders” (SBOIL). The SBOIL project is a continuation of the BioBind project, the primary goal of which was to develop and deploy an oil recovery system designed for use in coastal waters and adverse weather conditions. The goal of the SBOIL project was to use this new technology to improve the current response capabilities for cross-border oil spills. The developed application allows for the determination of the position of an aircraft at the time of dropping the oil binders, the determination of the oil binders’ position after falling in terms of a specific aircraft’s position, the determination of the position of oil binders after a certain time in order to plan the action of recovering it from the water surface, and the determination of the time when the binders will be in their assumed position.

ABSTRACT This paper describes a simple approach to quantifying progress and benefits associated with improvements in oil spill removal technology over the past decade, focusing on the most significant oil removal technologies: mechanical recovery, dispersant application and in-situ burning. All three technologies have been the focus of research and development (R&D) efforts since the Exxon Valdez spill. Notable progress has been made in refining the technologies and defining circumstances under which each option will be successful. These accomplishments have been qualitatively described in recent strategic technology assessments. The difficulty that arises in quantitatively predicting future benefits of these advances, is that expected increases in oil removal and associated cost savings are as much a function of specific circumstances of future spills as of advances in spill removal technologies. The specifics of future spills, particularly the larger more troublesome ones, are difficult to predict. In order to obtain representative quantitative estimates of these benefits, a hind-cast technique is demonstrated whereby the advanced technologies are applied to past spill scenarios to determine oil recovery and cost savings that would be realized if these spills were to occur in the future.

ABSTRACT The marine salvage and commercial diving industries have increasingly been sought out to prevent oil spills from submerged shipwrecks, and to detect and recover spilled oil below the surface once a subsea spill occurs. In recent years, underwater oil recovery techniques have advanced from predominantly surface-supplied diver installed vacuum or pumping systems in relatively shallow waters to the use of saturation diving systems and remotely operated vehicles at greater depths. Underwater oil detection technologies have advanced permitting the detection of spilled oil in the water column, on the bottom and in the subsurface. For oil trapped within a sunken shipwreck, neutron backscatter technology has been successfully applied to locate oil inside the ship. Additionally, the International Maritime Organization, U.S. Coast Guard and National Oceanic and Atmospheric Administration have published regulations, guidance and studies in the past five years in an effort to improve submerged oil detection and recovery operations. This technical paper will provide an overview of the regulatory framework, basics of underwater oil spill response operations and an analysis of recent technological advances available to detect and recover oil at depth. Multi-beam sonar, real-time mass spectrometry, saturation diving systems, diver-operated recovery systems, and remotely operated vehicle systems will be discussed. Recent case studies will frame the presentation of advances in subsea oil detection and recovery equipment. Finally, conclusions and recommendations will be presented to further advance submerged oil detection and recovery efficiency and effectiveness.

ABSTRACT It has been noticed, in the latest Brazilian oil spill emergencies, that the time of arrival of equipaments in the emergency site, due to some differents facts (Brazilian dimensions, transport infrastructure, Customes etc) was of 48–60 hours. Furthermore, one may notice that all the Brazilian oil spill response equipment was not enough for Tier 2 and 3 emergencies. Petrobras has decided to install a total of nine Oil Spill Response Centers, strategically located throughout Brazil, thus increasing its response capacity for potential oil spills. Each of the Centers is equipped with special barges, oil recovery boats, skimmers, sorbents, containment and sorbent booms. Equipments and logistic support can be rapidly dispatched to any area in Brazil where an emergency might occur. The CDAs operate with about 250 trained technicians, available 24 hours per day. This provides regularly trained skills, together with Petrobras technicians and the local communities, in order to guarantee readiness in the event of a spill. Some data about how and where the Centers have been working after two years operation are now shown. In fact, the CDAs have been participating in a lot of response calls, although most of them are inspections for prevention, supporting the Petrobras’ units operations, other companies’ emergencies and ocasional oil spills. However, it should be noted that Brazil has more capacity to face oil-related emergencies than before.

There was suggested a method of obtaining a complex adsorbent with magnetic properties for the oil spill clean-up from the water surface by means of controlled magnetic field. As magnetic filler a finely-dispersed iron-ore concentrate in the form of magnetite, obtained by wet magnetic separation of crushed iron ore, was suggested. As an adsorbing component the disintegrating electric-furnace steelmaking slag, obtained by dry air-cooling method, was selected. The mass ratio of components slag:magnetite is 1(1,5÷2,0). For cleaning up emergency oil spills with the suggested magnetic adsorbent a facility, which is installed on a twin-hulled oil recovery vessel, was designed. The vessel contains a rectangular case between the vessel hulls with inlet and outlet for the treated water, the bottom of which is a permanently moving belt. Above the belt, at the end point of it there is an oil-gathering drum with magnetic system. The adsorbent is poured to oil-products layer from a hopper, provided with drum feeder. Due to the increased bulk weight the adsorbent sinks rapidly into the oil layer on the water surface. If the large non-floating flocculi are formed, they sink and sedimentate on the moving belt and are moved to the oil-gathering drum. The saturated adsorbent is removed from the drum surface with a scraper, connected with a gutter, with contains a rotating auger.

International experience of oil spill response in the sea defines the priority of coastal protection and the need to identify as most valuable in ecological terms and the most vulnerable areas. Methodological approaches to the assessing the vulnerability of Arctic coasts to oil spills based on international systems of Environmental Sensitivity Index (ESI) and geomorphological zoning are considered in the article. The comprehensive environmental and geomorphological approach allowed us to form the morphodynamic basis for the classification of seacoasts and try to adapt the international system of indexes to the shores of the Kara Sea taking into account the specific natural conditions. This work has improved the expert assessments of the vulnerability and resilience of the seacoasts.

The Baltic

The Baltic Sea is a unique and sensitive brackish-water ecosystem vulnerable to damage from shipping activities. Despite high levels of maritime safety in the area, there is a continued risk of oil spills and associated harmful environmental impacts. Achieving common situational awareness between oil spill response decision makers and other actors, such as merchant vessel and Vessel Traffic Service center operators, is an important step to minimizing detrimental effects. This paper presents the Next-Generation Smart Response Web (NG-SRW), a web-based application to aid decision making concerning oil spill response. This tool aims to provide, dynamically and interactively, relevant information on oil spills. By integrating the analysis and visualization of dynamic spill features with the sensitivity of environmental elements and value of human uses, the benefits of potential response actions can be compared, helping to develop an appropriate response strategy. The oil spill process simulation enables the response authorities to judge better the complexity and dynamic behavior of the systems and processes behind the potential environmental impact assessment and thereby better control the oil combat action.

First Time

The application of chemical dispersants during marine oil spills can affect the community composition and activity of marine microorganisms. Several studies have indicated that certain marine hydrocarbon-degrading bacteria, such as Marinobacter spp., can be inhibited by chemical dispersants, resulting in lower abundances and/or reduced biodegradation rates. However, a major knowledge gap exists regarding the mechanisms underlying these physiological effects. Here, we performed comparative proteomics of the Deepwater Horizon isolate Marinobacter sp. TT1 grown under different conditions. Strain TT1 received different carbon sources (pyruvate vs. n-hexadecane) with and without added dispersant (Corexit EC9500A). Additional treatments contained crude oil in the form of a water-accommodated fraction (WAF) or chemically-enhanced WAF (CEWAF; with Corexit). For the first time, we identified the proteins associated with alkane metabolism and alginate biosynthesis in strain TT1, report on its potential for aromatic hydrocarbon biodegradation and present a protein-based proposed metabolism of Corexit components as carbon substrates. Our findings revealed that Corexit exposure affects hydrocarbon metabolism, chemotactic motility, biofilm formation, and induces solvent tolerance mechanisms, like efflux pumps, in strain TT1. This study provides novel insights into dispersant impacts on microbial hydrocarbon degraders that should be taken into consideration for future oil spill response actions.
