Perairan Karawang merupakan salah satu perairan yang dilintasi Alur Laut Kepulauan Indonesia (ALKI) dimana kapal-kapal besar dan kapal tanker melintasi area perairan ini. Pada bagian utara Perairan Karawang juga terdapat kegiatan pengeboran migas (minyak dan gas) sumur bor milik salah satu perusahaan minyak dan gas nasional, sehingga Perairan Karawang dan sekitarnya mempunyai resiko yang tinggi terhadap tumpahan minyak. Tujuan penelitian ini adalah untuk memperkirakan luasan pola persebaran tumpahan minyak mentah (crude oil) akibat kebocoran sumur bor di perairan Karawang dan wilayah perairan di sekitarnya. Penelitian ini dibagi menjadi dua tahapan, yaitu tahap survei lapangan dan tahap pemodelan numerik. Pemodelan numerik terdiri dari pemodelan arus, sebaran tumpahan minyak, dan nasib  (fate) minyak setelah tumpah yang masing-masing dimodelkan menggunakan model matematika dua dimensi Penelitian ini menggunakan metode kuantitatif dan untuk menentukan lokasi pengukuran menggunakan metode purposive sampling. Trayektori Sebaran tumpahan minyak mentah (crude oil) dominan bergerak dari sumur bor pada koordinat 107°37′32.52″E dan 06°5’39”S menuju ke arah barat, bergerak dari Perairan Karawang menuju Perairan Bekasi. Hal itu terjadi karena peristiwa minyak tumpah terjadi musim timur, yakni arus dominan bergerak dari arah timur dan tenggara menuju ke arah barat dan barat laut. Daerah terdampak tumpahan minyak ini meliputi Kabupaten Karawang dan Kabupaten Bekasi, khususnya wilayah Perairan Kecamatan Muara Gembong dengan luasan sebaran tumpahan minyak sekitar 249.91 km2.   Karawang waters is one of the waters crossed by the Indonesian Archipelago Sea Channel (ALKI) where large ships and tankers cross this water area. In the northern part of Karawang Waters, there is also oil and gas (oil and gas) drilling activities which are owned by one of the national oil and gas companies, so that the Karawang waters and surrounding areas have a high risk of oil spills. The purpose of this study was to estimate the extent of the distribution pattern of crude oil spills due to leakage of wells in the waters of Karawang and the surrounding waters. This research was divided into two stages, namely the field survey stage and the numerical modeling stage. Numerical modeling consists of modeling the flow, distribution of oil spills, and the fate of oil after spilling, each of which is modeled using 2 dimension mathematical model. This study uses quantitative methods and to determine the location of measurements using the purposive sampling method. Trajectory The dominant distribution of crude oil spills moves from the wellbore at coordinates 107 ° 37′32.52 ″ E and 06 ° 5'39 "S heading westward, moving from Karawang Waters to Bekasi Waters. This happened because the oil spill event occurred in the east season, which is the dominant current moving from east and southeast to west and northwest. Areas affected by the oil spill include Karawang Regency and Bekasi Regency, especially the waters of the Muara Gembong District with an area of distribution of oil spills around 249.91 km2.

Crude oil spills are a major threat to marine biota and the environment. When light crude oil spills on water, it forms a thin layer that is difficult to clean by any methods of oil spill response. Under these circumstances, a special type of amphiphile termed as “chemical herder” is sprayed onto the water surrounding the spilled oil. The amphiphile forms a monomolecular layer on the water surface, reducing the air–sea surface tension and causing the oil slick to retract into a thick mass that can be burnt in situ. The current best-known chemical herders are chemically stable and nonbiodegradable, and hence remain in the marine ecosystem for years. We architect an eco-friendly, sacrificial, and effective green herder derived from the plant-based small-molecule phytol, which is abundant in the marine environment, as an alternative to the current chemical herders. Phytol consists of a regularly branched chain of isoprene units that form the hydrophobe of the amphiphile; the chain is esterified to cationic groups to form the polar group. The ester linkage is proximal to an allyl bond in phytol, which facilitates the hydrolysis of the amphiphile after adsorption to the sea surface into the phytol hydrophobic tail, which along with the unhydrolyzed herder, remains on the surface to maintain herding action, and the cationic group, which dissolves into the water column. Eventual degradation of the phytol tail and dilution of the cation make these sacrificial amphiphiles eco-friendly. The herding behavior of phytol-based amphiphiles is evaluated as a function of time, temperature, and water salinity to examine their versatility under different conditions, ranging from ice-cold water to hot water. The green chemical herder retracted oil slicks by up to ~500, 700, and 2500% at 5°, 20°, and 35°C, respectively, during the first 10 min of the experiment, which is on a par with the current best chemical herders in practice.

<p><em>This study aims to analyze a blowout from an oil and gas leak owned by PTT Exploration and Production (PTTEP) Australasia in the Montara oil field in the Indonesian Timor Sea, and how to resolve disputes between Australia and Indonesia. A qualitative approach was used in this study, whilst the data collection technique was through library research. The theory of state responsibility, the concept of human security, and the concept of international maritime law are used to analyze disputes between Indonesia and Australia. The study found that the Montara oil spill had not only damaged the marine ecosystem but also polluted Indonesian waters. It also found that although the Australian government had formed a special commission to resolve cases and even used dispersant, it had not satisfied all parties. Several points are summarized. First, the Montara oil spill in Australia is a transnational study because the impact has crossed national borders. Secondly, UNCLOS has a weakness in the settlement of the Montara case because the Convention only provides a description related to ‘Responsibility of Each Country’ and does not specifically arrange material compensation mechanisms to countries that cause sea pollution. Third, the Montara oil spill has caused huge losses for Indonesian seaweed farmers, especially 13 districts in NTT. The recommendations are that the Indonesian government along with the Montara Victim Peoples’ Advocacy Team should continue to follow up the case of oil spills from the Montara platform and continue to fight for compensation to the Australian government and the PTTEP as the responsible party.</em></p>

ABSTRACT Oil spills only occur after the start-up of a facility but oil spill prevention for a pipeline-terminal-tanker complex begins with route selection and continues through design, construction, personnel training, operation and maintenance. The trans-Alaska pipeline project has faced all of the usual, and some unusual, problems which needed solutions to give maximum assurance that oil spills would not occur during the operating life of the facilities. This conference today is considering the prevention of oil spill incidents associated with tanker and pipeline operations, refineries, and transfer and storage terminals. The trans-Alaska pipeline system is concerned with each of these functions of the petroleum industry. Alyeska Pipeline Service Company is responsible for design, construction, operation, and maintenance of the pipeline system which will move crude oil produced on the Alaskan North Slope along a route to Valdez, an ice free port located on an arm of Prince William Sound. At Valdez, the oil will be transferred to ocean going tankers. The project will have at its ultimate design capacity of two million barrels per day:Almost 800 miles of 48-inch pipeline.Twelve pump stations with 650,000 installed HP.Twenty-million barrels of crude oil storage in fifty-two tanks.Five loading berths at a deep water terminal servicing a fleet of tankers ranging in size from 30,000 dwt to 250,000 dwt.Eight crude oil topping plants, manufacturing fuel for pump stations, each with a charge of 10,000 barrels per day.A ballast water treating plant capable of handling up to 800,000 barrels per day of dirty ballast.A 25,000 KW power generation plant.Several dozen mechanical refrigeration plants which will be freezing the ground in Alaska.

ABSTRACT Oil spills are one of the major concerns associated with oil and gas development along the outer continental shelf. The U.S. Department of the Interior is presently planning lease sales at the rate of seven per year. Many of these leases are being proposed in areas where the risks associated with oil spills are difficult to assess. The major objective of the decisionmakers in this process is to select a leasing plan from the list of proposed blocks that will offer the maximum production potential within an acceptable level of environmental risk. This objective can be obtained with proper contingency planning which should include site-specific designs. A proposed leasing plan could be limited in its production potential by the habitats more vunerable to a potential oil spill. These areas are identified using a model system developed by the U.S. Geological Survey. In this model, the local meteorology and physical oceanography are coupled to produce trajectories of hypothetical oil spills. These trajectories, along with oil resource estimates, are used to establish overall probabilities of an oil spill contacting specific coastal areas and habitats. Using linear programming techniques, the blocks that can yield the maximum resource recovery within specified limits of environmental risk are identified. Site-specific contingency measures (such as stockpiles of cleanup equipment) concentrated at the more vulnerable habitats will allow the decisionmaker to accept a higher level of environmental risk and significantly increase the number of blocks that are suitable for leasing. A proposed lease sale area for the northeast Gulf of Alaska is used to demonstrate the importance of contingency planning in determining various levels of offshore oil and gas resource development.

ABSTRACT The Center for Fire Research (CFR) at the National Institute of Standards and Technology (NIST) is conducting research related to safety in offshore drilling and oil spill pollution under joint funding from Minerals Management Service (MMS), U.S. Coast Guard, and the American Petroleum Institute. Technical assistance in measurement has been donated by Environment Canada. This research has focused on examining the phenomena associated with crude oil combustion and the impact of using burning as a spill response method. The process of burning crude oil on water as a means to mitigate oil spills has been investigated with a research effort combining both small-scale experiments and calculations. As a result of these studies, there has been increased understanding of the burning process, including burning rate, heat radiation, smoke emission, smoke composition, and smoke dispersion in the atmosphere. A key to gaining acceptance of burning as a spill response technique is the demonstration that favorable results obtained at laboratory scale can be shown to continue in test burns representing the size of fires expected in actual operations. Field-scale burn tests are being planned and coordinated jointly by MMS, API, USCG, and Environment Canada to document the use of burning technology under conditions simulating actual oil spill cleanup operations. The purpose of this project is to measure the effects of oil spill burning in laboratory and field tests.

Offshore Oil

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.

St Lawrence River

ABSTRACT The St. Lawrence River, situated between Canada and the United States, provides a major transport route in North America for the transport of millions of tons of crude oil, condensates, and refined products each year. In addition, as one of the largest rivers in the world, it is of major ecological significance. For example, over 55,000 hectares of wetlands are found along the St. Lawrence alone. These areas provide habitat for wildlife, the nurseries for fisheries, and control coastal erosion are highly vulnerable to oil spills. Furthermore, as traditional oil spill cleanup methods may be ineffective or cause more damage, emergency responders are considering less intrusive methods such as biorestoration as operational countermeasures. A biorestoration experiment was designed to measure the effectiveness of this method in the St. Lawrence River. To conduct this experiment, 1,200 liters of crude oil were to be spilled in a controlled manner over an experimental zone of 750 m2 in a marsh area. To obtain regulatory approvals from governmental agencies, environmental groups and, more importantly, to avoid the “not in my backyard” protests from the local communities, site selection, emergency planning, contingency measures, and especially community meetings, were all necessary steps towards the acceptance of the project. This controlled spill was done in June 1998 without any incident. Sampling of the experimental site will be completed in the fall of 2000. This paper aims to provide insights on the steps needed to gain acceptance from concerned citizens for the conduct of a controlled oil spill experiment.

Objectives: To describe the acute health impacts of the Deepwater Horizon oil spill in Louisiana as compared with the acute health impacts reported from prior crude oil spills. To predict potential chronic health impacts in Louisiana as compared with the chronic health impacts reported from prior crude oil spills.Setting: Offshore and onshore coastal southeastern Louisiana.Patients and participants: Oil spill offshore and onshore cleanup workers and the general population of coastal southeastern Louisiana.Interventions: Not applicable to an observational study.Main outcome measures: Adverse acute health effects of petrochemical and dispersant exposures in highly exposed offshore and onshore cleanup workers and the general population; prior chronic adverse health effects reported from prior oil spills; and predicted chronic adverse health effects based on intensity of chemical exposures and on seroprevalences of genetic polymorphisms.Results: Acute health effects in cleanup workers mirrored those reported in cleanup workers following prior oil spills as ranked by systems (and by symptoms). Acute health effects in lesser exposed members of the general population mirrored those reported in similar coastal residents following prior oil spills but differed from cleanup workers as ranked by systems (and symptoms).Conclusions: Subpopulations of cleanup workers and the general population with specific conditions or genetic polymorphisms in enzyme systems that detoxify polycyclic aromatic hydrocarbons in petrochemicals and glycols in dispersants will require long-term surveillance for chronic adverse health effects including cancer, liver and kidney diseases, mental health disorders, and fetal alcohol spectrum disorders.

An oil spill is discharge of fluid petroleum such as crude oil or its by-product derivations such as diesel and gasoline on the water surface. In this paper, a numerical model of the oil spill has been introduced as a simulation of releasing oil on the sea surface. Meantime, the influence of sea waves and wind has been considered and shown. Moreover, a swarm of robots is engaged in order to track the spreading boundaries of the slicked oil, so that a novel schedule of robot locomotion is presented, based on the online sharing information in the flock network. Therefore, the swarm of robots tracks the oil spill margins intelligently and successfully.
