Therefore, in 2001 the Government implemented a federal legislation requiring oil spill response plans (OSRP) which was strongly inspired in the United States requirement for ports and terminals. In 2016, an interdisciplinary task force was initiated to improve this legislation. Thus, a new risk-based framework was developed in order to better engage some of the environmental and social-economical complexities of Brazil as adequate inputs for the oil spill response planning process. This methodology was expanded from the guidelines published by International Association of Oil & Gas Producers (IOGP).\u0000 First, the concept of sensitive receptors were introduced to describe any valuable element that can be harmed by the spill. These were selected from environmental sensitivities, protection areas, wildlife occurrence, human occupation, tourism and fisheries, among others. These criticalities were categorized in five classes using an oil slick forecast modelling results for different spill volumes such as the minimum time to reach these receptors and oiling probability. After this, they were associated with certain spill volumes, resulting in three possible requirement levels. Consequently, the minimum response capability demand for the facility is calculated, as well as tactical and logistics plans. This new approach not only optimizes the allocation of first response equipment at the highest risk spots, but also regulates the sharing of these capabilities when there is a concentration of these facilities.\u0000 In this paper, this methodology was applied to a major oil terminal located in a high sensitivity area at Ilha Grande Bay, in Rio de Janeiro. The worst-case scenario was around 6.923 c.m., which allowed the identification of 116 vulnerable receptors. Of these, 02 were identified as having high criticality and, therefore, were prioritized for response planning. The minimum nominal response capability was estimated as being equal to 4.760 m3/day for full deployment condition after the initial 60 hours. This value is about 25% higher than that predicted in facility's existing OSRP. However, with the application of resource sharing rules, the amount of equipment staged on site is equal to only 1298 m3/d, allowing a significant optimization due to logistics processes after the initial 24h.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"124 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88825321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kuosa","doi":"10.7901/2169-3358-2021.1.687464","DOIUrl":"https://doi.org/10.7901/2169-3358-2021.1.687464","url":null,"abstract":"\u0000 An oil spill reaching ashore may generate massive amounts of oiled waste as oil contaminates soil, vegetation and floating debris. The resulting volume of oiled waste may be multiple compared with the original volume of spilt oil. The Finnish authorities responsible for the oil spill response in nearshore waters have calculated that the target scenario, to which the national and regional contingency plans should respond, is an oil spill of 30 000 tonnes resulting in over 500 000 tonnes of oily wastes. Safe and efficient handling of that waste volume requires a thorough pre-planning. As the capacities of the waste disposal facilities are mainly measured up to the domestic wastes, temporary arrangements will be necessary. Further, in order to maximize the differentiated capacities of each available disposal plant, the wastes should be segregated. Segregation also decreases the costs related to the final disposal. In Finland, where the coastline is ragged and, in some places, difficult to access, the logistic chain of wastes may consist of several stages and transportation modes. The complexity of the transportation chain combined with the requirement of segregation will challenge the waste management during an incident. Therefore, contingency plans are developed to include also site-specific logistic plans with pre-defined transportation and storage points. In addition, easy-to-use segregation guidelines are produced using colour codes for different waste types together with the inserted Quick Response (QR) codes to provide segregation instructions. To keep track on the segregated waste units, the Radio-Frequency Identification (RFID) technology might provide a useful option. This paper examines the usability of RFID tracking in oil spill response waste management. The observations are based on field exercises aiming to study the benefits of technology using RFID tags and RFID readers. The aim of the exercises was also to determine the quality and quantity of the data needed to be stored on tags in different transportation scenarios. In addition, this paper introduces the QR segregation guideline and its interoperability with the identification and tracking technology tested.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89501352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Before this operator led LSE, capping equipment had not been deployed in Africa. Since this was the first exercise of the sort to be undertaken in Nigeria, there were several objectives defined at the outset of the exercise: test the entire response chain (logistics, preparation, execution and communication);demonstrate to the Nigerian authorities that a comprehensive and efficient response could be executed in a timely manner; anddocument, record lessons learned and then feed them back to the local affiliate and others to improve future response operations\u0000 For this exercise, TOTAL deployed its Subsea Emergency Response System (SERS) which was commissioned for construction at the beginning of 2012. Two systems were developed for drilling and production hydrocarbon blowout scenarios. The LSE's focus was to deploy the capping system while also taking the opportunity to simulate pumping dispersant. TOTAL has two SERS's that are stored in Pointe Noire, Congo and Luanda, Angola. Due to the readiness of the system in Congo (recently tested and the appropriate connector installed), it was chosen to be used for the LSE.\u0000 An abandoned appraisal well was chosen for the exercise due to it being free from subsea infrastructure. The detailed work scope for the LSE was as follows:\u0000 SERS ○ Controls Distribution Unit (CDU) deployment○ Flying Lead Deployment Frame (FLDF) deployment○ Diverter Spool Assembly (DSA) deployment○ Connection of the Hydraulic Flying Leads (HFL's) and Electric Flying Leads (EFL's)○ Landing the DSA and locking the connector by Remote Operated Vehicle (ROV)○ Performing an Acoustic Communication System (ACS) test\u0000 Subsea Dispersant Injection (SSDI) ○ Deploying the Hose Deployment Frame (HDF)○ Deploying the routing manifold on Coiled Tubing (CT)○ Connecting all hoses with the ROV○ Simulating pumping dispersant over the well\u0000 All equipment was successfully deployed and tested with all objectives achieved.

For the Deepwater Horizon (DWH) Oil Spill, the analytical chemistry data and toxicity study data were required to be validated in accordance with U.S. Environmental Protection Agency's (EPA's) data validation for Superfund program methods. The process of validating data according to EPA guidelines is a manual and time-consuming process focused on chemistry results for individual samples within a single data package to assess if data meet quality control criteria. In hindsight, the burden of validating all of the chemistry data appears to be excessive, and for some parameters unnecessary, which was costly and slowed the process of disseminating data. Depending on the data use (e.g., assessing human and ecological risk, qualitative oil tracking, or forensic fingerprinting), data validation may not be needed in every circumstance or for every data type.\u0000 Publicly available water column, sediment, and oil chemistry analytical data associated with the DWH Oil Spill, obtained from the Gulf of Mexico Research Initiative Information and Data Cooperative data portal were evaluated to understand the impact, effort, accuracy, and benefit of the data validation process.

Completion of the form requires consideration of environmental, archeocultural, and socio-economic resources that may be affected by a spill. This process of research, identification, prioritization, documentation, and communication of potential resources in the pathway of a spill is typically conducted within the Environmental Unit (EU) by the Resources at Risk (RAR) Technical Specialist or Environmental Unit Leader (EUL), with input from relevant stakeholders and trustees. The purpose of the form is twofold: to provide environmental information to aid assessment and decision making, for example: identifying where to conduct wildlife reconnaissance surveys, identifying resources of concern for Spill Impact Mitigation Assessment (SIMA)/ Net Environmental Benefit Analysis (NEBA), and recommending cleanup techniques and endpoints; andTo provide direct priorities for protection for response operations, such as from pre-established Geographic Response Plans (GRPs) or Geographic Response Strategies (GRSs), and other static or Geographic Informational Systems (GIS) data sources.\u0000 In recent years, GRP/GRSs have become more commonplace in contingency plans, and have become more practical for response operations, to a degree that some plans include executing the GRP/GRSs as ready-made ICS 204 (work order) forms to provide direct instruction to response operations on site location, access, operational strategies, and equipment required to protect specific resources. This pre-spill information can be valuable to ensure that priority resources are protected within the short window of opportunity that is typically available at the beginning of a response; and allows quick decision-making without the need for in-depth consideration of sensitivity and resource maps. A potential downside to this convenient data, which will be explored in this paper, is that we risk relying entirely on using the GRP data to provide operational protection priorities and losing the specific data on the resources we are aiming to protect. This reduces the purpose of the form to a purely operational instruction, without the documentation of environmental data that is essential for assessment and decision making within the Environmental Unit. This paper considers the use of the ICS 232 (Resources at Risk) form, how its use has developed over the years, and how the availability of GRPs has, in some areas, shifted the use of the form to a more directly operational purpose. Recommendations are provided for ensuring that the environmental information component is not forgotten.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74319800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the event of an oil or fuel spill at sea, in situ burning can be a practical method of removing the oil and preventing it from reaching vulnerable coastlines. However, the specific chemistry of the oil and its resulting behavior dictates how well this method works. In order to understand this behavior, Santa Barbara Channel crude oils were tested and burned in combinations of fresh, weathered, and seawater-emulsified at discrete ratios. A cone calorimeter was used to monitor time to ignition, mass loss, heat release rate, and smoke production for laboratory-scale burn tests. Weathering generally increased ignition time, but also changed the miscibility with water; this changed both heat released and burn efficiency. Emulsions with seawater fractions below approximately 20 % were found to improve the heat release rate and burn efficiency compared to oil-only burns; suggesting that some water emulsification can benefit oil burning. The results indicate that a targeted approach to the type of oil and degree of emulsification can expand the window of opportunity for in situ oil burns.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73142545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is also a significant refinement and transportation of petroleum products (by rail, pipeline, and vessel) within this area and in our transboundary waters. In Washington alone, more than 20 billion gallons are moved through and across the state on an annual basis. The Northwest Area Committee (NWAC) and Region 10 Regional Response Team (RRT10), the federally mandated bodies which conduct oil pollution and hazardous materials spill response planning, are therefore robust and very active. Within the last decade, tribal engagement in the NWAC and RRT10 has expanded significantly; the RRT10 now has three official tribal members, and the NWAC has supported a Tribal Engagement Task Force for the past four years and is currently looking at transitioning it to a longer-term and more permanent sub-committee strategy. This presentation will discuss the following pieces of the efforts towards tribal engagement in the NWAC/RRT10: 1) The evolution of tribal engagement in the RRT10/NWAC and lessons learned from this process 2) A case study of the unique experience of the Makah Tribe's engagement with the greater response community including both becoming the first tribal member of the NWAC/RRT10 and the development of their memorandum of agreement with the US Coast Guard, and 3) Results from the 2019 Tribal Engagement Task Force's tribal feedback survey (sent out to all Tribes in the region) to identify barriers and strategies for improved meaningful tribal engagement. This reflects the commitment of the NWAC/RRT10 to improving tribal engagement by understanding; the results can not only inform partners in other regions but will inform the next phase of the NWAC/RRT10's approach to tribal engagement.

The main objective of the operation was to deploy sensor package from a remotely-operated vehicle (ROV) to survey, detect, and map the location(s) of hydrocarbon emissions that are responsible for the surface oil spill and sheen footprint in the Mississippi Canyon Area. The objectives have been accomplished by conducting a multi-day, three-part survey mapping the area of interest, generation of georeferenced charts and 3D visualizations with detected oil active spills, all supported by a ROV intervention outfitted with oil spill detection and recognition system SpiDeR.\u0000 SpiDeR is a modular sensor suite capable of detecting, recognizing the source and classifying the hydrocarbon underwater leaks. The sensor suit with selectable configuration can be installed on any type of ROV vehicle and interfaces to the ROV with a single cable conducting the power and data.
