“…Cleanup costs on a per-ton basis decrease significantly with increasing amounts of oil: Smaller spills are often more expensive on a per-ton basis than larger spills because of the costs associated with setting up the cleanup response, bringing in the equipment and labour, and bringing in the experts to evaluate the situation (Etkin, 1999). However, two of these aspects will reduce costs per ton only on a continuous flat coast.…”

“…The spill correction factor s=1+sp(m) (where m is the mass spilled) used in Etkin's two models (Etkin, 1999(Etkin, , 2000 is given by means of tables for sp with step discontinuities between different categories of m. Both models could be fitted to a function of the following form: where c is a constant value for small spills, a is an initial mobilization cost, bf(m) is a unit cost that is assumed to depend on m and b is a constant. Etkin's first model (Etkin, 1999) After the introduction of the euro, it seems more realistic to use a European mean cost of €8600 per ton instead of using national costs.…”

SUMMARY: The sinking of the supertanker Prestige off the coast of Spain in November 2002 was one of the most devastating oil spills ever worldwide. During any crisis most of the decisions have to be taken with limited information and they can benefit greatly from a rational methodology based on the available information. The main mechanisms involved in oil spill impacts are reviewed and we propose a decision tree based only on scientific criteria and data that are expected to be available in the first moments of an oil spill crisis. In the Prestige crisis, one of the decisions taken was to sail the Prestige out to sea. This paper makes an independent analysis of that decision to illustrate the methodology proposed, which may help decision making in future emergency situations.Keywords: oil spill, response planning, Prestige, operational oceanography, deep sea, Atlantic Ocean. RESUMEN: Conduciendo al Prestige mar adentro. Un análisis independiente. -El hundimiento del petrolero Prestige frente a las costas españolas en noviembre de 2002 ha constituido uno de los vertidos más devastadores producidos en el mundo. Durante una crisis, la mayor parte de las decisiones han de ser tomadas con información limitada y pueden beneficiarse enormemente de una metodología racional que se base en la información disponible. Este artículo revisa los principales mecanismos que afectan al impacto de un vertido de petróleo y propone un árbol de decisión basado sólo en criterios científicos y datos que se puede esperar estarán disponibles en los primeros instantes de una crisis por vertido. En la crisis del Prestige, una de las decisiones tomadas fue la de conducir al barco mar adentro. Este artículo hace un análisis independiente de esa decisión con el fin de ilustrar la metodología propuesta, que puede ayudar a tomar la mejor decisión en futuras situaciones de emergencia.Palabras clave: vertido de petróleo, plan de respuesta, Prestige, oceanografía operacional, mar abierto, Océano Atlántico.

Abstract-Oil spills have tremendous effects on environment, ecology, economy, and the society as a whole. There are several techniques being used for oil spill cleanup i.e in-situ burning of oil, mechanical tools (booms and skimmers), chemical dispersants, steam flushing and also by using natural fibers as sorbents. In this research, oil sorbent material was produced from kenaf (Hibiscus cannabinus L.) fibers. Three sorbent materials were made from of various fiber particle sizes and tested for their oil absorbent properties. The results showed that sorbent produced from a 1.70 cm 2 -sized kenaf fibers achieved the highest absorption value of 8.2327 g/g and saturation value of 0.0385 N/Mins respectively. In this study, the 1.70 cm 2 -sized sorbent also demonstrated the strongest fiber bonding compared to those of 0.04 cm 2 -sized and 0.80 cm 2 -sized sorbents. This was confirmed by microstructure analysis conducted using a Scanning Electron Microscope (SEM). The oil sorbent materials produced in this study were found to have superior absorption value compared to other fiber-based oil sorbents such as Sisal (Agave sisalana), Coir (Cocos nucifera) and loofa sponge (Luffa cylindrica). Index terms-Sorbent materials, kenaf, Hibiscus cannabinus L., oil spill. I. INTRODUCTIONPollution resulting from oil spills poses severe environmental problems around the world. The oil spills pollution not only affects the environment with regard to its hazard but the clean up processes could be costly. In the year 1997, it was estimated that more than USD 136000/tonne spilled were spent for cleaning oil spills in the US alone [1]. The processes involved in cleaning oil spill were normally very complicated and not environmentally friendly [2]. The treatment for oil spills including chemical, mechanical and biological treatments [3]. In mechanical treatment, absorbent of synthetic or natural materials is an effective cost saving option [4].Despite their superior absorption qualities, synthetic materials have low biodegradability. Therefore natural based absorbent material is preferred due to its non toxicity and excellent biodegradability. In recent decades, natural sorbents were produced from natural biomass such as cotton (Gossypium hirsutium), kapok (Ceiba pentandra) [4], Sisal (Agave sisalana), Coir (Cocos nucifera) and loofa sponge (Luffa cylindrica) [5]. This study aims to produce sorbent material from kenaf fiber and to assess its absorption Manuscript received May 6, 2014; revised October 14, 2014 capacity. Kenaf tree (Hibiscus cannabinus L.) is a plant that originated from Africa. The second most important natural fiber after cotton, kenaf is an environmentally friendly plant certified by the Kyoto Protocol for it is obtained from renewable and recyclable source [6]. In Malaysian context, the National Kenaf and Tobacco Board are extensively promoting the application of kenaf as feedstock in manufacturing industries [7].The evaluation of kenaf-based sorbent properties in treating oil spills and waste water treatment are scarc...

Terms of use: Documents in Assessing the Risk of Oil Spills in the Mediterranean: the Case of the Route from the Black Sea to Italy SummaryRecent major spills on European coasts have highlighted the primary policy relevance for the EU of oil spills. This paper assesses the risks related to carrying oil to the EU along the route from the Russian Black Sea coast to Sicily, Italy (one of the most congested and strategically relevant European import routes). We develop a methodology based on Fault Tree Analysis, and we apply it to the most likely causes of an oil spill. We couple the resulting probabilities with data on expected spill size, types of oil carried and cleanup costs, to estimate expected costs for cleanup and loss of cargo. The route analysed appears to be a risky one; there is a "high" to "very high" risk of a spill along this route. The Turkish Straits turn out to be the major danger point; however, there is no obvious hierarchy amongst the other sites along the route.
