The southern part of Bintuni Bay with highly sensitive ecosystem conditions has evolved into an oil and gas industry where potential impacts on coastal and offshore environments need to be anticipated and planned comprehensively for environmental protection from oil spills. The main problem is the determination of areas that are sensitive and vulnerable to oil spills. This study is to analyze the factors and components that affect the level of environmental sensitivity and mapping Environment Sensitivity Index (ESI) to the oil spill.  The study was carried out by identifying and assessing each land units of its and use. Land use and land cover are interpreted through the use of satellite imagery with classification methods of guided satellite imagery. Field survey was also conducted in order to improve the accuracy of land use interpretation. Data analysis was performed by spatially by GIS method. The result indicated that ESI can be divided into five categories, are very sensitive (2,395.98 hectares or 2.38%), sensitive (13,133.53 hectares or 13.07%), moderately sensitive (17,902.78 hectares or 17.81%), low sensitive (52,409.14 hectares or 52.14%) and not sensitive (14,681.48 hectares or 14.61%). Although the study area is dominated by low sensitivity category, however the coastal protection from oil spill still should be prioritized.Keywords:  coastal protection, Environmental Sensitivity Index, Oil Spill, Bintuni Bay Wilayah bagian selatan Teluk Bintuni dengan kondisi ekosistem yang sangat sensitif telah berkembang menjadi industri minyak dan gas dimana potensi dampaknya terhadap lingkungan pesisir dan lepas pantai  perlu diantisipasi dan terencana secara komprehensif untuk perlindungan lingkungan dari kemungkinan tumpahan minyak.

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.

ABSTRACT Brazil has performed an important role in the oil and gas industry mainly because its offshore E&P activities. The volume of oil produced in offshore fields had increased 88% in the last decade and correspond to more than 90% of national production. The maritime Exploration and Production (E&P) operations in Brazil started in the middle of the 1970's. In 1981 a law was promulgated to establish a compulsory environmental permit to many activities, including oil and gas exploration and production activities. Although this regulation has existed for over 25 years, only in 1999 was it effectively brought into force to the E&P sector, with the creation of the oil and gas specialized office integrated to the Intituto Brasileiro de Meio Ambiente e Recursos Naturais Renováveis – IBAMA (Brazilian Federal Environmental Agency). On January 2000 Brazil faced one its worst oil spills, in Guanabara Bay. A broken pipeline owned and operated by Petrobras spilt 1300 tone of bunker fuel into Guanabara Bay, Rio de Janeiro. At that time, Brazil had no clear environmental scenario regarding the oil industry in Brazil: uncoordinated environmental regulations, debilitated environmental agencies and a relapse industry took part in the scenario. As a result of the repercussion of the disaster, in the same year was enacted the Federal Law 9966/2000, the so called “Oil Law”, on the prevention, control and inspection of pollution caused by the releasing of oil and other harmful substances in waters under national jurisdiction. The provisions of the Law 9966 included, among other things, the requirement for the notification to the competent environmental authority, the maritime authority and the oil regulating agency, of any incident which might cause water pollution. Although IBAMA receives the oil spill communications since 2001, only in 2010 the Agency began to include this information in a database. This paper discusses the offshore oil spill data received between 2010 and 2012.

ABSTRACT Hydrocarbon-degrading bacteria naturally degrade and remove petroleum pollutants, yet baselines do not currently exist for these critical microorganisms in many regions where the oil and gas industry is active. Furthermore, understanding how a baseline community changes across the seasons and its potential to respond to an oil spill event are prerequisites for predicting their response to elevated hydrocarbon exposures. In this study, 16S rRNA gene-based profiling was used to assess the spatiotemporal variability of baseline bacterioplankton community composition in the Faroe-Shetland Channel (FSC), a deepwater sub-Arctic region where the oil and gas industry has been active for the last 40 years. Over a period of 2 years, we captured the diversity of the bacterioplankton community within distinct water masses (defined by their temperature and salinity) that have a distinct geographic origin (Atlantic or Nordic), depth, and direction of flow. We demonstrate that bacterioplankton communities were significantly different across water samples of contrasting origin and depth. Taxa of known hydrocarbon-degrading bacteria were observed at higher-than-anticipated abundances in water masses originating in the Nordic Seas, suggesting these organisms are sustained by an unconfirmed source of oil input in that region. In the event of an oil spill, our results suggest that the response of these organisms is severely hindered by the low temperatures and nutrient levels that are typical for the FSC. IMPORTANCE Oil spills at sea are one of the most disastrous anthropogenic pollution events, with the Deepwater Horizon spill providing a testament to how profoundly the health of marine ecosystems and the livelihood of its coastal inhabitants can be severely impacted by spilled oil. The fate of oil in the environment is largely dictated by the presence and activities of natural communities of oil-degrading bacteria. While a significant effort was made to monitor and track the microbial response and degradation of the oil in the water column in the wake of the Deepwater Horizon spill, the lack of baseline data on the microbiology of the Gulf of Mexico confounded scientists’ abilities to provide an accurate assessment of how the system responded relative to prespill conditions. This data gap highlights the need for long-term microbial ocean observatories in regions at high risk of oil spills. Here, we provide the first microbiological baseline established for a subarctic region experiencing high oil and gas industry activity, the northeast Atlantic, but with no apparent oil seepage or spillage. We also explore the presence, relative abundances, and seasonal dynamics of indigenous hydrocarbon-degrading communities. These data will advance the development of models to predict the behavior of such organisms in the event of a major oil spill in this region and potentially impact bioremediation strategies by enhancing the activities of these organisms in breaking down the oil.

The Environmental Sensitivity Index (ESI) mapping has been used globally for oil spill planning and response purposes in coastal areas since its development in the 1970s. However, application to riverine habitats has been very limited.  Following US National Oceanic and Atmospheric Administration (NOAA) formats and adapting them in working sessions held by a multidisciplinary team and in special sessions with experts and consultants in Colombia, this paper describes the development and application of the sensitivity index to develop maps for the conditions of the middle Magdalena River in Colombia.  The index developed (ESI-R) is useful for application on other major rivers in Colombia and areas with similar characteristics.  The use of the index to develop maps for smaller rivers and streams is likely to require further development.

<p>This study was conducted to analysis of the Environmental Sensitivity Index (ESI) for anticipating the effect of oil spills on the environment in coastal areas. The study location is the coastal area and waters of the Karas District, Fakfak Regency, West Papua Province, Indonesia. The purpose of the study is to determine the priority of areas that are sensitive to oil spills. This method was carried out by scoring each unit of land based on vulnerability, conservation, and social values. ESI Analysis was carried out through geographic information systems and classified into 5 classes of sensitivity levels. The land use classification was carried out through satellite imagery and field surveys conducted in December 2018. The results of resource classification can be divided into 16 classes. The ESI analysis showed that most (51%) were categorized as insensitive, sensitive low 24%, very sensitive 15%, moderately sensitive 6%, and sensitive 4%. Although most are not sensitive, it should be followed by effective environmental protection to maintain sustainable development.</p>

The study of the coastal and shallow marine geomorphology of the adjacent bays of Anavyssos and Aghios Nikolaos (southeastern Attica) was carried out by acoustic scanning of the seafloor with an echo sounder and sonar side scan; topographical sections perpendicular to the shoreline, collection and analysis of surface sediments; determination of long-term shoreline displacements by comparing old and modern aerial photographs and satellite imagery. The terrestrial part of the coastal area consists of many landforms, such as lagoons, cliffs, beachrocks, tombola etc. The beaches affected by intense human activity have gentle slopes, low elevations and a coarse-grained texture. The remote sensing analysis showed that, over the last six decades, there are some small shoreline changes of the order of ± 2 meters. The bays have relatively gentle gradients covered by sand in their shallower parts and patches of Posidonia Oceanica towards the open sea. Taken into account the texture of sediments and landforms that make up the terrestrial part of the coasts, four categories (1st, 2nd, 3rd and 5th) of Environmental Sensitivity Index for oil spill (ESI) have been identified and an ESI map is created serving as a quick reference for oil spill responders and coastal zone managers.

Abstract The Brazilian oil spill response main regulation has been under a major review for the last couple of years. The origins of this regulation date back to the year 2000, when two accidents of great relevance happened: the Guanabara Bay and the Iguaçu River oil spills. These two accidents quickened the promulgation of the first version of this regulation, an adaptation of the USA framework for facilities transferring oil or hazardous material in bulk (33 CFR part 154). The major changes made during this adaptation to the Brazilian laws were: 01) The scope has been expanded to cover not only transferring coastal facilities, like ports and Abstract number oil terminals, but also oil rigs, offshore oil production units, pipelines and refineries. In a later revision other facilities were included: marinas, onshore oil rigs, shipyards and nautical clubs; 02) The response resources could only be provided by the owner of the facility, which has restrained the potential benefits of a shared capability approach like, for example, a specialized response company or association that could support several facilities in a region; In practice, the application of the same ground rule for inland, coastal and offshore facilities resulted in several distortions, like a dominance of the mechanical removal technique over other response techniques. This also resulted in the application of response time requirements designed for oil terminals to offshore facilities, resulting in an oversized dedicated oil spill response fleet. In addition, this rule is inadequate to linear spill sources, like marine pipelines, and inland facilities, like refineries. Finally, because of the aforementioned distortions and also some lack of technical guidance for relevant topics, like coastal protection, oil trajectory forecasting modelling, wildlife response planning, among others, several different interpretations of the national regulation have arrived from different levels of governmental agencies. This not only allowed for distinct requirements over time from a same agency but also created confusion when comparing the response capabilities of similar installations from different regions of Brazil. Thus, the purpose of this article is to describe the improvements proposed by the Oil and Gas producers to review the Brazilian regulation. It aims at presenting the key elements and references used in the review process and the predicted response structure that could arise in order to improve Brazil's environmental safety after the new regulation is in force.

One of the serious environmental problems of the oil and gas industry is handling oil spills. Oil spills can be managed by using bioremediation in the form of biosurfactants. In this research, biosurfactants called U-Champ were used which can impact in remediation of oil spills. The research conducted was testing the effectiveness of biosurfactants on Cepu Field contaminated soil in reducing TPH and heavy metals. The method is done by stirring the contaminated soil with various concentrations of biosurfactant product in an artificial tank. Based on the test results, a decline in TPH and TCLP along with the increase in U-Champ biosurfactant concentration was used. The addition of 6 Liters of biosurfactant gave the most significant reduction. Some of the heavy metals in the soil decrease, but some also have increased. As an example, it can be seen in Ba metal, the addition of U-Champ biosurfactant as much as 1.5 L (0.3% v / v) resulted in a decrease in TCLP of 11.085%. The qualitative result is evidenced by the growth of various plants in each artificial tank.
