Em termos metodológicos, a pesquisa se apoiou na revisão sistemática da literatura adotada tanto para oferecer o devido embasamento teórico sobre licença social para operar e justiça ambiental, quanto para apoiar a construção de instrumentos de coleta de dados aplicados junto a distintos stakeholders. Dentre os resultados destacaram-se: a necessidade de um maior esforço por um diálogo para além dos requisitos legais para licenciamento dos empreendimentos, assim como a busca por uma maior contribuição da academia e poder público na comunicação e esclarecimentos sobre os riscos e impactos locais do empreendimento, e suas respectivas oportunidades, quando existem. / This study aims to analyze the impacts of the implementation from LNG projects (liquefied natural gas) and LPG (liquefied petroleum gas) by an oil company and natural gas to the fisherfolk of Magé, State of Rio de Janeiro in the period 2007-2016. In terms of methodology, the research relied on the systematic review of the literature to both provide theoretical basis of social license to operate and environmental justice, and to support the construction of data collection instruments applied along the different stakeholders. The results highlighted the need for a greater effort for dialog beyond the legal requirements for the licensing of enterprises, as well as the search for a greater contribution of academia and public power in communication on the local risks and impacts, as their opportunities, when it exists.

L’influence des multinationales pétrolières dans la société contemporaine est devenue un élément central de la problématique relative aux droits de l’homme et au développement durable. Elles sont maintenant très nombreuses à opérer dans le secteur public et privé avec des stratégies et objectifs particulièrement divers. Grâce à des budgets conséquents, et une technologie complexe et avant-gardiste, elles sont responsables de l’exploration, de la production, du raffinage et de la distribution du pétrole brut. Cela dit, dans le but de pointer du doigt les déséquilibres importants dans les relations entre l’industrie pétrolière et les pays en développement, la commission mondiale sur l’environnement et le développement a très tôt mis en avant le terme de « développement durable », se caractérisant par un « développement qui répond aux besoins du présent sans compromettre la capacité des générations futures à répondre aux leurs ». Le secteur pétrolier et gazier est déjà depuis un certain temps un leader en matière de responsabilité sociale. Les compagnies pétrolières attachent de plus en plus d’importance à leur impact économique, social et environnemental et elles font aussi de plus en plus attention à leur image. En plus d’autres éléments, ce phénomène se démontre par l’extraordinaire augmentation des codes de conduite et par des initiatives relatives à la responsabilité sociale comme le « global compact » de Kofi Annan. Cela dit, l’efficacité de ces initiatives est souvent remise en question et il existe un certain nombre de preuves attestant du fossé existant entre les déclarations de principes et le véritable comportement des acteurs sur le terrain. Toute la question est donc de savoir si une conciliation est possible. Mots- / The influence of Multinational oil corporations in contemporary society is becoming an increasingly central element of human rights and sustainable development problematic. There are now many MNOCs operating in both private and public sectors with remarkably diverse objectives and strategies. Thanks to large budgets and complex advanced technology, they are responsible for exploration, production, refining and crude oil distribution. In order to address the imbalance between industrial oil and lessdeveloped countries, the world commission on environment and development has early pointed up the term « sustainable development » which is « that meets the needs of the present without compromising the ability of future generations to meet their own needs ». As a result, the oil and gas sector has been among the leading industries in championing Corporate Social Responsibility a while ago. Oil companies attach greater importance to their economical, social and environmental impact and they also pay more and more attention to their image. Among other things, this phenomenon is demonstrated by the extraordinary growth in corporate codes of conduct and CSR initiatives such as Kofi Annan’s Global Compact. However, the effectiveness of these initiatives has been regularly questioned and there is a mounting evidence of a gap between the statements of principles and the real actor’s behaviour on the field. Finally, is a conciliation possible?

This dissertation is an examination of the American oil industry in Saudi Arabia and its influence on United States foreign policy. The study examines the Americans who went to Saudi Arabia, the effect of the oil companies on Saudi- American relations, and the American government's response to oil company actions. There is an attempt to answer such questions as: Did the oil companies exert pressure on the American government to influence governmental policy? How effective was this pressure? And, what benefits did the oil companies have from their relationship with the government? The study concludes that Aramco was instrumental in bringing official and nonofficial contact and representation between Saudi Arabia and the United States. Moreover, Aramco was instrumental in involving the American government directly in Saudi Arabia through the extension of lend-lease aid to that country. American government involvement thwarted potential British ambitions in the Saudi oil resources and resulted in the American dominance of oil interests in that kingdom. In addition, Senate investigations showed that the oil companies grossly overcharged the United States Navy on oil purchases and that the financial assistance to Saudi Arabia was made for the protection of Aramco's oil concession.

Um aprimoramento de nosso federalismo fiscal, com maior descentraliza????o de recursos e implementa????o de regras de transfer??ncias federativas com maiores incentivos pr??-efici??ncia ??? aumentando os incentivos pr??-obten????o de melhores resultados sociais por parte das unidades subfederadas ??? pode se revelar instrumento importante na melhoria de nossas condi????es sociais. Para isto, dividiu-se esta tese em quatro partes distintas. No primeiro cap??tulo, discutem-se os impactos das receitas petrol??feras sobre as finan??as p??blicas municipais. As mudan??as legais ocorridas no pa??s na d??cada de noventa do ??ltimo s??culo - relativas ao setor petrol??fero - levaram a crescente (e concentrada) transfer??ncia de recursos do setor para os estados e munic??pios brasileiros. A forte sensa????o que estes estariam sendo desperdi??ados de alguma forma vem suscitando discuss??es sobre a necessidade de se reformular sua distribui????o. As recentes descobertas de megacampos petrol??feros no pr??-sal do litoral brasileiro somente intensificaram este processo. Buscou-se identificar os efeitos destas transfer??ncias sobre as vari??veis fiscais municipais no pa??s. Detectou-se que n??o ocorreu substitui????o tribut??ria, ou seja, estes recursos n??o diminu??ram o esfor??o arrecadat??rio dos munic??pios. Em compensa????o, tanto os recursos cuja distribui????o ?? bem mais concentrada (referentes aos royalties excedentes) quanto aqueles mais bem-distribu??dos (referentes aos royalties originais) levaram as prefeituras a aumentar seus gastos correntes (piorando sua composi????o do ponto de vista social) e diminuir seus investimentos. O contr??rio parece ocorrer com os recursos cuja distribui????o se d?? de forma intermedi??ria (os royalties referentes ??s participa????es especiais. No segundo cap??tulo, discute-se o impacto das receitas petrol??feras sobre a profici??ncia dos alunos at?? a quarta s??rie prim??ria das escolas p??blicas municipais. As receitas petrol??feras ??? agregadas ou n??o ??? n??o se mostraram estatisticamente significativas na explica????o do desempenho observado pelos alunos da quarta s??rie prim??ria das escolas municipais em portugu??s ou matem??tica. Este resultado, entretanto, deve ser olhado com cautela, uma vez que n??o ?? trivial identificar como (e o tempo necess??rio) estes efeitos seriam gerados. Entretanto, diferentes fontes de receitas municipais impactariam de forma diferenciada as profici??ncias observadas nos testes de portugu??s e matem??tica, explicitando a necessidade de se entender melhor estas diferen??as para se desenhar mecanismo mais eficiente de repasse de recursos constitucionais aos munic??pios. No terceiro cap??tulo, estudam-se os impactos das emancipa????es municipais ocorridas na d??cada de 90 sobre o bem-estar das popula????es locais. Devido ?? Constitui????o Federal de 1988, o n??mero de munic??pios no Brasil multiplicou-se fortemente na d??cada de 90 do ??ltimo s??culo. Mais de mil munic??pios foram criados em todo o pa??s, fazendo seu n??mero ultrapassar a casa dos 5.500. Este processo tem sido interpretado de forma bastante negativa. Baseado em evid??ncias aned??ticas, se pressup??e que os atores pol??ticos locais o utilizaram para se apropriar de maior parcela dos recursos transferidos de outros n??veis governamentais. Entretanto, nenhum esfor??o mais sistem??tico foi realizado buscando calcular, de maneira efetiva, os resultados sociais l??quidos deste processo. ?? isto que se busca fazer aqui, utilizando dados sobre os munic??pios mineiros - cujo n??mero passa de 723 em 1991 para 853 em 2000. Foram detectados impactos positivos relacionados a diversas vari??veis educacionais e de sa??de. Ao mesmo tempo, o contr??rio ocorreu com os indicadores de pobreza e indig??ncia. Este resultado mostra que o movimento observado de emancipa????o municipal talvez tenha sido bastante ben??fico, sinalizando para a exist??ncia de mercados pol??ticos eficientes nestas localidades, o que indicaria a necessidade de se manter uma maior autonomia local relativa a processos de emancipa????o de distritos. Por fim, no quarto cap??tulo, analisam-se os impactos de lei (implementada em Minas Gerais) que buscou aumentar os incentivos pr??-efici??ncia das prefeituras municipais a partir das transfer??ncias federativas. Buscando melhorar as condi????es de vida dos munic??pios mineiros, o governo estadual mineiro instituiu, em 1995, a lei 12.040, conhecida como Lei Robin Hood. Esta permitia que 25% dos recursos de ICMS a serem distribu??dos aos munic??pios mineiros se dessem sobre resultados observ??veis em diversas ??reas tais como sa??de, educa????o, conserva????o ecol??gica, entre outras. Ou seja, esta institu??a, em rela????o a estas transfer??ncias, um contrato de alto poder com os munic??pios relacionados ??s pol??ticas p??blicas implementadas. O estudo destas transfer??ncias (relativas ?? educa????o e sa??de) mostrou resultados d??bios. Resultados positivos relativos ?? educa????o e ?? sa??de parecem ocorrer em todo o estado, mas os incentivos dados poderiam ser bem maiores - faz-se necess??rio um refinamento das regras da partilha destas transfer??ncias. Dada a relativa escassez deste tipo de contrato em transfer??ncias federativas, seja no Brasil, seja no restante do mundo, este resultado aponta a necessidade de utiliza????o de instrumentos de maior poder nas rela????es federativas, buscando incrementar as condi????es de vida locais. / This thesis aims to discuss municipal public finance issues. An improvement of the Brazilian fiscal federalism, with greater resources decentralization and the implementation of high-powered rules for the federative transfers may be an important tool in the improvement of our social conditions. To do so, this thesis was divided into four distinct parts. The first chapter discusses the oil revenues impacts on municipalities??? public finance. The legal changes that occurred in Brazil in the nineties in the oil and gas sector led to increasing royalties transfers to Brazilians states and municipalities. The annedoctical evidence that this transfers are not been used properly - in a way that would increment the local welfare - have originated a important discussion about these distribution rules. This paper tries to identify this revenues impacts over others municipalities??? fiscal variables. It seems that this did not impact the others sources of municipalities revenue. Unhappily, some of the resources (which distribution is either more or less concentrated) led the municipalities to increase their current expenditures and diminishes their investments efforts. At the same time, they are not spending this extra money in a way that would increment the local welfare. On the other hand, the resources which distribution is between these two limits has the opposite effect. The second chapter discusses the impact of oil revenues on the proficiency of fourth grade students of primary public schools. The oil revenues - bundled or not - were not statistically significant in explaining the observed student performance in Portuguese and mathematics. This result, however, must be analyzed with caution, since it is not trivial to identify how (and when) these effects would be generated. However, different sources of municipal revenue would impact differently the students??? proficiency scores, explaining why we need to better understand these differences to design more efficient constitutional transfer mechanisms to the municipalities. In the third chapter, we study the impacts of municipal emancipation occurred in the 90s on the well-being of local populations. More than a thousand of new municipalities were created at the nineties in Brazil, due the new Federal Constitution of 1988. There is anecdotic evidence that this was a pretty harmful process for the Brazilian welfare, but there were no systematic attempt to valuate it properly. This paper tries to do so using data from Minas Gerais municipalities which number has grown from 723 to 853 ones in that decade. The results suggest that this process strongly improved the welfare of the local population. This implies that local political markets are efficient and it should be allowed for any district to emancipate from its former municipalities, if their population wishes to do so. Finally, in the fourth chapter we analyze the impact of law (implemented in Minas Gerais) who sought to increase the incentives pro-efficiency of municipal governments. In order to improve the welfare of its citizens, the state government of Minas Gerais (Brazil) has imposed, at 1995, the state law 12.040, known as Robin Hood law. It stated that 25% of the revenue transferred to the municipalities should be allocated through observable results achieved in education, health, environment among others. In other words, this law established a high power contract between the state government and the municipalities, which is not very usual. This study shows that this law had a significant impact on the municipalities??? education and health. But it???s necessary to redesign these transfers??? rules, in order to improve its power and its results. These results shows that the use of high powered rules in federative transfers could be a strong mechanism in order to improve the population welfare. / Economia e Finan??as

A case study was performed in a Brazilian oil industry that produces crude oil in o shore platforms, that is, located in the ocean, and transports to the terminals located in the Brazilian coast. Then, it was proposed a mixed integer model to represent the problem adequately and for this, a detailed analysis of the real problem in order to know all its characteristics and consider some simplifying assumptions. Therefore, to the pickup and delivery problem with time windows present in the literature were aggregated other speci c restrictions of the case study, for example, multiple depots, ship mooring restrictions, exible draft and dynamic positioning. Besides that, the eet is heterogeneous related to capacity, LOA (length overall), dynamic positioning and velocity. In practice, in general there are no identical vessels. This problem can be represented as a combinatorial optimization model, which belongs to the NP-hard class and its solution is a challenging in practice depending on the size of the real problems. Then, were proposed several exact branch-and-cut methods based on models with 2 and 3-index variables for routing problems with pickup and delivery and time windows to solve speci cally the Brazilian oil industry problem. Finally, we proposed a branch-and-price method, which includes all characteristics of the problem in oil industry. In summary, the main contributions of this thesis are related to the study and modeling of this problem in practice, and the proposal and development of exact solution methods to solve it, based on branch-and-cut and branch-and-price. The performance of the mathematical model in optimization software and the exact methods were veri ed using a real data set provided by the company. Results show that these approaches may be e ective to solve problems of moderate size in real situations. / O objeto de estudo deste trabalho é o problema de roteamento e programação de navios com coleta e entrega e janelas de tempo na indústria petrolífera. Foi realizado um estudo de caso com uma empresa petrolífera brasileira que produz óleo cru em plataformas o shore, isto é, localizadas no oceano e os transporta até os terminais localizados na costa brasileira. Então, foi proposto um modelo de programação inteira mista para representar o problema adequadamente e para isso, foi necessária uma análise detalhada do problema real, com o intuito de conhecer todas as suas características e considerar hipóteses simpli cadoras. Desta maneira, ao problema de coleta e entrega e janelas de tempo da literatura foram agregadas outras restrições especí cas do problema do estudo de caso como, por exemplo, múltiplos depósitos, restrições de atracação dos navios, calado exível e posicionamento dinâmico. Além disso, a frota de navios é heterogênea em relação à capacidade, LOA (length overall ), posicionamento dinâmico e velocidade. Na prática, em geral não existem navios iguais. Este problema pode ser representado como um modelo de otimização combinatória que pertence à classe NP-difícil e sua solução é bastante desa adora na prática em função do tamanho dos problemas reais. Depois, foram propostos vários métodos do tipo branch-and-cut baseados em modelos com variáveis de 2 e 3-índices para problemas de roteamento com coleta e entrega e janelas de tempo para resolver especi camente o problema da empresa brasileira. E por m, foi proposto um método do tipo branch-and-price, o qual abrange todas as características do problema da indústria petrolífera. Em síntese, as principais contribuições desta tese referem-se ao estudo e modelagem deste problema na prática, e a proposta e desenvolvimento de métodos de solução exatos para resolvê-lo, baseados em branch-and-cut e branch-and-price. O desempenho do modelo matemático em softwares de otimização e também dos métodos exatos propostos foi veri cado usando-se exemplares reais fornecidos pela empresa. Os resultados mostram que essas abordagens podem ser efetivas para resolver problemas de tamanho moderado em situações reais.

No cenário teórico dessa disciplina, predominam os referenciais produzidos no ambiente anglo-americano, a prescrição de modelos estratégicos universais e a falta profundidade teórica e conceitual que ajude a melhor compreender o fenômeno das redes. Esse arcabouço teórico dominante na disciplina designa maior relevância e foco à tese da mercadização, que reproduz os princípios do neoliberalismo e marginaliza as demais teorias de mercado que também são de fundamental importância para a compreensão do desempenho das empresas e das redes. Exemplos de teorias marginalizadas são as que endereçam o reconhecimento das interfaces entre poder, política, mercado, Estado e sociedade. Especialmente em economias emergentes assim como em economias em transição, como é o caso do Brasil e de Portugal respectivamente, essas teorias marginalizadas revelam o reconhecimento de que estratégias de não-mercado são tão importantes quanto estratégias de mercado. Dada a atual relevância das operações envolvendo as organizações híbridas Petrobras e Galp, em especial na indústria petrolífera de Brasil e Portugal, por meio de um estudo de caso a presente dissertação busca identificar como e porque são formadas redes de organizações híbridas na indústria petrolífera luso-brasileira e como estratégias de mercado e de não-mercado interagem nessas redes. / Since discipline was born, strategy presents as its central characteristics the creation, the use and difusion of models that help to build and keep the major company’s strategist authority and the strong basement in economic theories and in the autonomous entity paradigm. Within its theoretical scenario, prevail the anglo american theories produced, the prescription of universal strategic models and the lack of theoretical and conceptual deepness that enables to better comprehend the network phenomenon. This dominant theoretical framework within the discipline gives more relevance and focus to the market thesis, that reproduces the neoliberalism principles and marginalizes the other market theories also important for the comprehension of the organizations and network performance. Some examples of marginal theories are those who address the recognizing of power, politics, market, State and society interfaces. Specially in emergent and transition economies, as Brasil and Portugal respectively, these marginal theories reveal the recognizing of non-market strategies are as important as market strategies. Considering the present relevance of operations involving the hybrid organizations Petrobras and Galp, in special in the Brazilian and Portuguese oil industries, through a case study this dissertation aims to identify how and why hybrid organizations networks are formed in the Brazilian-Portuguese oil industry and how market and non-market strategies interact in among these networks.

The work of an engineer is closely intertwined with safety. An engineer’s perception of the “safety” task is traditionally inherent in his or her design. However, in the technical world most machines and systems designed by engineers contain a human element, which engineers have to consider in their work. In the oil and gas upstream industry – especially drilling, production and workover operations – petroleum engineers (including drilling and production engineers) are responsible not only for design but also for operational and organizational aspects. The human factor becomes more important in complex offshore operations. Incorporating safety into a sys-tem design requires identifying, analyzing and evaluating risks and ensuring that any not accounted for are taken into consideration. This process requires communication among everyone involved in the process. Analysis of accidents in the oil and gas industry shows that often a lack of that communication led to incident triggering events. In this thesis, the author proposes a novel communication model that improves this exchange of information and supposedly makes the process of risk assessment more effective. In addition, the new model also incorporates factors such as emotions, feelings, needs and imagination into the risk assessment process. This broadens the information base for the risk identification and analysis and creates an atmosphere of psychological ownership for the stakeholders in the process, which leads to a perceived safety climate in the organization where the new model is applied. The innovative communication or consultation model, as it is also referred to in risk assessments, is based on a structured process used in conflict resolution called mediation. Mediation is an alternative conflict resolution process that is centered on mutual under-standing and listening to each other’s needs. The process is composed of elements that characterize it. These elements of mediation are used to assess other communication processes and to develop new communication models. The application of the elements of mediation and the safety-mediation consultation into the risk assessment process enables this process to be enhanced with human factors such as emotions, feelings, intuition and imagination. The inclusion of all stakeholders creates psychological ownership, improves communication, enables organizational learning and expands the knowledge base for risk analysis. The applicability of the safety-mediation consultation process for a human factor-based risk assessment is presented and tested using illustrative examples and field cases from the international oil and gas industry. Possible concerns and limitations are also discussed. This thesis shows that mediation and elements of the mediation process can be applied to improve communication in the international oil and gas industry. This is facilitated by educated safety mediators, who help the petroleum engineer and operational crew on a drilling rig to achieve a better understanding by ensuring that they hear and fully register each other’s needs.

L’application de la photoluminescence suscite un intérêt croissant de la part des chercheurs et ceci dans de nombreux domaines. Dans notre cas, différents complexes à base de lanthanide seront détectés par une méthode spectrophotométrique avancée, la fluorescence résolue en temps. Ces derniers peuvent être ainsi détectés même à l’état de traces au sein des milieux complexes tel que ceux rencontrés dans l’industrie pétrolière (saumures, traces de pétrole, éléments solides en suspension, etc.). L'utilisation de la détection de fluorescence résolue en temps combinée à des complexes de lanthanides a été démontrée comme une stratégie simple et efficace pour éliminer la fluorescence de fond des matrices présentes dans le milieu étudié et fournir un rapport signal sur bruit élevé. Le sujet de cette thèse consiste à répondre avec les outils précédents à différentes problématique existants au sein de l’industrie pétrolière, de l’extraction du pétrole au processus de marquage de différents produits raffinés à des fins commerciales. Dans la première partie du manuscrit décrira différents protocoles capables d’extraire de l’information de différents additifs chimiques employés sur les champs pétrolifères lors de l’extraction de pétrole et de gaz. Les additifs en questions peuvent être des inhibiteurs de dépôts minéraux, des inhibiteurs de corrosion, des polymères viscoélastiques, dans différentes eaux de synthèse et de production issues de différentes plateformes. Les impacts de certains facteurs ont été analysés afin d’améliorer la sensibilité et les performances. Nous démontrerons la possibilité de quantifier avec succès la teneur résiduelle de différents types d'additifs chimiques. L'effet de matrice de l’échantillon a été limité par le développement de deux stratégies d'addition standard. Nous montrerons par ailleurs qu’il est possible de quantifier la présence non seulement d’un additif mais encore, dans certaines situations optimisées, de deux additifs en mélange. Outre la détermination de la concentration en additifs chimiques, nous présenterons également une méthode permettant de déterminer l’anionicité d’un polymère en milieu complexe. Dans la deuxième partie du document, nous détaillerons le développement de complexes de lanthanides utilisés en tant que marqueurs ainsi que la méthode de détection par fluorescence résolue en temps visant à la lutte contre la contrefaçon de différents pétroles bruts et de carburants raffinés. La synthèse et le processus d’incorporation de trois types de marqueurs de photoluminescence et leur stabilité dans différents carburants seront ensuite discutés. Les résultats obtenus démontrent qu’il est possible, à l’aide de cette technologie de marquage, de détecter efficacement les fraudes à la taxe dans les carburants, même à haute dilution. Ces travaux présente potentiellement un fort impact dans les domaines académiques comme industriels. Toutes les études se concentrent sur la mise au point d’une procédure simple, qui fournit une sensibilité élevée permettant de réduire le coût de production et qui repose sur l’emploi du fluorimètre résolu en temps Inibox™ développé pendant ma thèse pour porter sur le terrain les technologies développé au laboratoire / The application of photoluminescence is receiving an increasing interest from researchers coming from many fields. The previous laboratory works introduced a time-resolved fluorescence (TRF) detection method for the quantification of chemicals in complex medium (petroleum, production brine, and synthetic sea water) tagged with lanthanides, the additives form complexes that exhibit specific TRF signal which overcomes autofluorescence of sample and provide a high signal to noise ratio. The subject of this thesis concerns the development of specific methods based on patented technique to answer problematics arising in the oil industry from the extraction of crude product to the distribution of fuels. In the first part of the document, we focus on the monitoring of residual amount of chemical additives such as scale inhibitors, corrosion inhibitors, viscoelastic polymers in different synthetic and production waters. The impacts of some key factors were analyzed in order to improve the sensitivity and performance, also proves that under optimized conditions it is possible to quantify simultaneously two products in the same matrix. We successfully quantified various types of chemical additives with satisfying precision. Furthermore, the matrix effect was controlled by the development of two standard addition strategies. In addition to the determination of the concentration of chemical additives, we will also introduce a method to determine the anionicity of a polymer in difficult conditions. In the second part of the manuscript we follow the development of lanthanide complex markers and their detection for anti-counterfeiting on different crude oils and refined fuels. The synthesis, incorporation process and stability of three types of photoluminescence markers in different fuels have been discussed. The obtained results will prove that the technology can be used to detect fraud on fuels. This work has a potential great impact for both the academic and industrial domains. All studies focus on the creation of a simple procedure, with high sensitivity and low cost. All method are relying in the end on a specific field apparatus developed during my thesis to support the exportation of the technologies from the laboratory to the industry: The Inibox™

The work of an engineer is closely intertwined with safety. An engineer’s perception of the “safety” task is traditionally inherent in his or her design. However, in the technical world most machines and systems designed by engineers contain a human element, which engineers have to consider in their work. In the oil and gas upstream industry – especially drilling, production and workover operations – petroleum engineers (including drilling and production engineers) are responsible not only for design but also for operational and organizational aspects. The human factor becomes more important in complex offshore operations. Incorporating safety into a sys-tem design requires identifying, analyzing and evaluating risks and ensuring that any not accounted for are taken into consideration. This process requires communication among everyone involved in the process. Analysis of accidents in the oil and gas industry shows that often a lack of that communication led to incident triggering events. In this thesis, the author proposes a novel communication model that improves this exchange of information and supposedly makes the process of risk assessment more effective. In addition, the new model also incorporates factors such as emotions, feelings, needs and imagination into the risk assessment process. This broadens the information base for the risk identification and analysis and creates an atmosphere of psychological ownership for the stakeholders in the process, which leads to a perceived safety climate in the organization where the new model is applied. The innovative communication or consultation model, as it is also referred to in risk assessments, is based on a structured process used in conflict resolution called mediation. Mediation is an alternative conflict resolution process that is centered on mutual under-standing and listening to each other’s needs. The process is composed of elements that characterize it. These elements of mediation are used to assess other communication processes and to develop new communication models. The application of the elements of mediation and the safety-mediation consultation into the risk assessment process enables this process to be enhanced with human factors such as emotions, feelings, intuition and imagination. The inclusion of all stakeholders creates psychological ownership, improves communication, enables organizational learning and expands the knowledge base for risk analysis. The applicability of the safety-mediation consultation process for a human factor-based risk assessment is presented and tested using illustrative examples and field cases from the international oil and gas industry. Possible concerns and limitations are also discussed. This thesis shows that mediation and elements of the mediation process can be applied to improve communication in the international oil and gas industry. This is facilitated by educated safety mediators, who help the petroleum engineer and operational crew on a drilling rig to achieve a better understanding by ensuring that they hear and fully register each other’s needs.

Tesis por compendio / [ES] El sector agroalimentario constituye una de las industrias con mayor relevancia. Durante la producción de aceite de oliva, se generan grandes volúmenes de subproductos, destacando el alperujo, que contiene todos los restos de la aceituna que permanecen una vez que se ha extraído el aceite. Se trata de un subproducto con una elevada carga orgánica, lo que puede suponer un riesgo ambiental si no se gestiona adecuadamente. Por otro lado, el alperujo es rico en compuestos fenólicos, los cuales tienen un elevado interés industrial, debido a sus propiedades antioxidantes. Esto representa una oportunidad excelente para valorizar el alperujo, recuperando compuestos de interés y reduciendo la carga contaminante del residuo. En esta Tesis Doctoral, se ha abordado este reto, en el marco de la Tecnología de Membranas. En primer lugar, se llevó a cabo la optimización de un proceso de extracción sólido-líquido asistida por ultrasonidos, para extraer los compuestos fenólicos presentes en el alperujo. Se obtuvieron resultados satisfactorios tanto con mezclas de etanol/agua como con agua pura. Además, se llevó a cabo una caracterización detallada de los metabolitos presentes en los extractos derivados del alperujo, de forma que se determinaron más de 50 compuestos. En las siguientes etapas, se emplearon tanto los extractos obtenidos con etanol/agua 50:50 (v/v) como los acuosos. En cuanto a estos últimos, se trataron mediante ultrafiltración, seleccionando las membranas UP005 y UH030, debido a su adecuada productividad y eficacia en términos de rechazo a la demanda química de oxígeno. Los compuestos fenólicos fueron recuperados con mayor pureza en el permeado de este proceso. A continuación, esta corriente de permeado fue sometida a un proceso de nanofiltración, empleando la membrana NF270 (DuPont), para llevar a cabo la concentración de los compuestos fenólicos previamente purificados. Además, se demostró la viabilidad de esta membrana, NF270, para separar compuestos fenólicos de bajo peso molecular y azúcares, empleando disoluciones modelo con una composición basada en las aguas residuales de la industria oleícola. Los extractos hidroalcohólicos de alperujo también fueron tratados mediante procesos de membrana. Previamente, se llevó a cabo una revisión exhaustiva de la literatura científica relacionada con la ultrafiltración en medio orgánico. A continuación, se evaluó un proceso de ultrafiltración para purificar los extractos de alperujo preparados con etanol/agua 50:50 (v/v), obteniendo resultados satisfactorios en cuanto a la estabilidad de las membranas (empleando las membranas UF010104 y UF010801v3, de la casa comercial SolSep BV, y UP005, de Microdyn Nadir) y la recuperación de compuestos fenólicos en el permeado. Para aumentar la pureza de estos compuestos fenólicos y abordar su fraccionamiento, se estudió un proceso de nanofiltración con disolventes orgánicos, empleando una disolución simulada, cuyo disolvente fue etanol/agua 50:50 (v/v), y con una composición basada en el permeado del proceso de ultrafiltración (con la membrana UP005) en medio orgánico. La membrana NF270 fue la más destacada, debido a su notable densidad de flujo de permeado. Además, esta membrana rechazó adecuadamente los compuestos no deseados, como azúcares y ácidos, lo que facilitó la recuperación satisfactoria de los compuestos fenólicos en el permeado. Considerando los resultados obtenidos, se propuso un proceso integrado basado en la extracción de estos compuestos con etanol/agua 50:50 (v/v), la ultrafiltración de este extracto, con la membrana UP005, para llevar a cabo su purificación, la nanofiltración, con la membrana NF270, de la corriente de permeado obtenida previamente, para aumentar la pureza y fraccionar los compuestos fenólicos y, finalmente, la concentración de la corriente de permeado obtenida durante la nanofiltración, mediante un proceso de ósmosis reversa, empleando la membrana NF90 (DuPont) que rechazó apropiadamente los compuestos fenólicos. / [CA] El sector agroalimentari constitueix una de les indústries amb major rellevància. Durant la producció d'oli d'oliva, es generen grans volums de subproductes, entre els quals destaca l'alperujo, que conté totes les restes de l'oliva que romanen una vegada que s'ha extret l'oli. Es tracta d'un subproducte amb una elevada càrrega orgànica, la qual cosa pot suposar un gran risc ambiental. D'altra banda, l'alperujo és ric en compostos fenòlics, els quals tenen un elevat interés industrial, degut a les seues propietats antioxidants. Aquest contingut en compostos bioactius representa una oportunitat excel·lent per a valorar l'alperujo, recuperant compostos d'interés i reduint la càrrega contaminant del residu. En aquesta Tesi Doctoral, s'ha abordat aquest repte, en el marc de la Tecnologia de Membranes. En primer lloc, es va dur a terme l'optimització d'un procés d'extracció sòlid-líquid assistida per ultrasons, per a extraure els compostos fenòlics presents a l'alperujo. Es van obtindre resultats satisfactoris tant amb mescles d'etanol/aigua com amb aigua pura. A més, es va dur a terme una caracterització detallada dels metabòlits presents en els extractes derivats de l'alperujo, de manera que es van determinar més de 50 compostos. En les següents etapes del procés, es van emprar tant els extractes obtinguts amb etanol/aigua 50:50 (v/v) com els extractes aquosos. Quant a aquests últims, es van tractar mitjançant ultrafiltració, estudiant les membranes, seleccionant les membranes UP005 i UH030, a causa de la seua adequada productivitat i eficàcia en termes de rebuig a la demanda química d'oxigen. Els compostos fenòlics van ser recuperats amb major puresa al permeat d'aquest procés. A continuació, el corrent de permeat obtinguda durant l'etapa d'ultrafiltració va ser sotmesa a un procés de nanofiltració, emprant la membrana NF270 (DuPont), per a dur a terme la concentració dels compostos fenòlics prèviament purificats. A més, es va demostrar la viabilitat d'aquesta membrana, NF270, per a separar compostos fenòlics de baix pes molecular i sucres, emprant dissolucions model. Els extractes hidroalcohòlics d'alperujo també van ser tractats mitjançant processos de membrana. Prèviament, es va dur a terme una revisió exhaustiva de la literatura científica relacionada amb la ultrafiltració al mig orgànic. A continuació, es va avaluar un procés d'ultrafiltració per a purificar els extractes d'alperujo preparats amb etanol/aigua 50:50 (v/v), obtenint resultats satisfactoris quant a l'estabilitat de les membranes (emprant les membranes UF010104 i UF010801v3, de la casa comercial SolSep BV, i UP005, de Microdyn Nadir) i la recuperació de compostos fenòlics, els quals es van obtindre en el corrent de permeat. Per augmentar la puresa d'aquests compostos fenòlics i abordar el seu fraccionament, es va estudiar un procés de nanofiltració amb dissolvents orgànics, utilitzant una dissolució simulada, que el seu dissolvent va ser etanol/aigua 50:50 (v/v), i amb una composició basada en el permeat del procés d'ultrafiltració al mig orgànic. D'entre totes les membranes, la membrana NF270 va ser la més destacada, a causa de la seua notable densitat de flux de permeat. A més, aquesta membrana va rebutjar adequadament els compostos no desitjats, com a sucres i àcids, la qual va facilitar la recuperació satisfactòria dels compostos fenòlics en el permeat. Considerant els resultats obtinguts, es va proposar un procés integrat basat en l'extracció d'aquests compostos amb etanol/aigua 50:50 (v/v), la ultrafiltració d'aquest extracte, amb la membrana UP005, per a dur a terme la seua purificació, la nanofiltració, amb la membrana NF270, del corrent de permeat obtinguda prèviament, per augmentar la puresa i fraccionar els compostos fenòlics i, finalment, la concentració del corrent de permeat obtinguda durant la nanofiltració, mitjançant un procés d'osmosi reversa, emprant la membrana NF90 (DuPont) que va rebutjar apropiadament els compostos fenòlics. / [EN] The agri-food sector is one of the industries with higher international relevance. During olive oil production, large volumes of by-products are generated. Among them, the wet olive pomace stands out. It contains all the olive components remaining after the olive oil extraction. This by-product has a high organic load, which may represent an environmental risk if it is not properly disposed. On the other side, the wet olive pomace is rich in phenolic compounds, which have high industrial interest due to their antioxidant properties. This content in bioactive compounds represents an excellent opportunity to valorize the wet olive pomace, recovering compounds of interest and reducing the contaminant load of the residue. In this Doctoral Thesis, this challenge has been addressed, in the framework of Membrane Technology. First, an ultrasound-assisted solid-liquid extraction was optimized to extract the phenolic compounds from wet olive pomace. Satisfactory results were obtained, both with mixtures of ethanol/water and with pure water. Furthermore, a detailed characterization of the metabolites present in the extracts derived from wet olive pomace was conducted. More than 50 compounds were determined. During the following stages, both the extracts obtained with ethanol/water 50:50 (v/v) and the aqueous extracts were considered. The aqueous extracts were treated by ultrafiltration, selecting the UP005 and UH030 membranes, due to their suitable productivity and efficacy, in terms of the rejection of the chemical oxygen demand. The phenolic compounds were recovered at a higher purity in the permeate. Afterwards, the ultrafiltration permeate was treated by nanofiltration, employing the NF270 membrane (DuPont), in order to concentrate the previously purified phenolic compounds. Moreover, the feasibility of the NF270 membrane to separate low-molecular-weight phenolic compounds from sugars was demonstrated. To that end, simulated solutions, with a composition based on olive mill wastewaters, were employed. The hydroalcoholic extracts of wet olive pomace were also treated by membrane processes. Previously, an exhaustive review of the scientific literature related to organic-solvent ultrafiltration was addressed. Later, it was evaluated an ultrafiltration process to purify the wet olive pomace extracts prepared with ethanol/water 50:50 (v/v). Satisfactory results were obtained, regarding the membranes stability (UF010104 and UF010801v3, from the manufacturer SolSep BV, and UP005, from Microdyn Nadir) and the recovery of phenolic compounds. These molecules were obtained in the permeate stream. To increase the purity of the phenolic compounds and address their fractionation, an organic-solvent nanofiltration process was studied. A simulated solution, whose solvent was ethanol/water 50:50 (v/v), was employed. The composition of this solution was based on the UP005 permeate obtained in organic media. Among all the evaluated membranes, the NF270 membrane stood out due to the high permeate flux. Furthermore, this membrane properly rejected the unwanted compounds, such as sugars and acids. This allowed the satisfactory recovery of phenolic compounds in the permeate stream, after their purification and fractionation. Considering these results, an integrated process was proposed. It was based on the extraction of the compounds of interest with ethanol/water 50:50 (v/v), and a further ultrafiltration, nanofiltration, and reverse osmosis process. The ultrafiltration of the extract was performed with the UP005 membrane to conduct its purification. Then, the UP005 permeate was nanofiltered, employing the NF270 membrane to enhance the purity of the phenolic compounds and fractionate them. Finally, the NF270 permeate was concentrated by means of a reverse osmosis process, employing the NF90 membrane (DuPont), which suitably rejected the phenolic compounds. / Sánchez Arévalo, CM.
