Decision-making Tool For Knowledge-based Projects In Offshore Production Systems
No full textThe development of an offshore field demands knowledge of many experts to choose the different components of an offshore production system. All the specialized parts of this knowledge are intrinsically related. The aim of this paper is to use Fuzzy Sets and knowledge-based systems to describe and formalize the phases of development of an offshore production system project, in order to share and to manage the required knowledge for carrying out a project, while at the same time proposing alternatives for the oil field configuration. © Springer-Verlag Berlin Heidelberg 2012.7637 LNAI692701et al.,Sociedad Colombiana de Computacion (SCo2),Universidad de Caldas,Universidad Nacional de Colombia,Universidad Tecnologica de Bolivar en Cartagena,Universidad Tecnologica de PereiraPublisher: Springer VerlagWang, X., Chan, C.W., Hamilton, H.J., Design of knowledge-based systems with the ontology-domain-system approach (2002) 14th International Conference on Software Engineering and Knowledge Engineering, pp. 233-236. , Ischia, Italy, July 15-19Bargach, S., Martin, C.A., Smith, R.G., Managing drilling knowledge for improved efficiency and reduced operational risk (2001) SPE/IADC Drilling Conference, p. 67821Chao, K.M., Smith, P., Hills, W., Florida-James, B., Norman, P., Knowledge sharing and reuse for engineering design integration (1998) Expert Systems with App., 14 (3), pp. 399-408Soh, C.K., Soh, A.K., An approach to automate the design of fixed offshore platforms (1993) Computers & Structures, 46 (4), pp. 221-254Franco, K.P.M., Morooka, C.K., Mendes, J.R.P., Guilherme, I.R., Desenvolvimento de um sistema inteligente para auxiliar a escolha de sistema para produção no mar (2002) 2o Congresso Brasileiro de P&D em Petróleo & Gás, Rio de Janeiro, , in portugueseSerapião, A.B.S., Guilherme, I.R., Morooka, C.K., Mendes, J.R.P., Franco, K.P.M., Um sistema inteligente para escolha dentre alternativas de sistemas marítimos de produção (2003) VI Simpósio Brasileiro de Inte Ligência Artificial, Bauru-SP, , Brazil In PortugueseKlir, G.J., Yuan, B., (1995) Fuzzy Sets and Fuzzy Logic-Theory and Applications, , 1st edn Prentice-Hal
Real Options Applied To Selection Of Technological Alternative For Offshore Oilfield Development
No full textThe future outcome of a project is not usually predictable, and therefore uncertainty plays an important role into the process. Current economic models that support decision-making process are not always capable of indicating and accounting for the benefits of flexible field development plans. One way to resolve this is to add real options valuation (ROV) into the economic model and to expand the decision-making process to accommodate this technique. The work presented on the paper describes a methodology that incorporates ROV into the analysis of different field development alternatives for deepwater. Examples are presented in this paper to demonstrate that there is a difference in the total value of the projects when flexibility is accounted for. It is also highlighted the different manners that flexibility contributes to the project value and how to model a field development plan in order to analyse its flexibility.21752179Trigeorgis, L., (1996) Real Options - Managerial Flexibility and Strategy in Resource Allocation, p. 427. , MIT Press, Cambridge, MADezen, F., Morooka, C., Adding Real Options Value To Decision Analysis (2000) Rio Oil & Gas Conference, , Conference held in Rio de Janeiro, Brazil, October.

New view of strategy: An interview with C.K. Prahalad
No full text'Strategic intent', 'core competence' and 'strategy as stretch and leverage', are all management concepts that have become associated with C.K. Prahalad and his frequent co-author, Gary Hamel, most often in the pages of the Harvard Business Review, but also in other journals and books. These ideas now form the basis of much new thinking about competitiveness by strategic managers. With the publication in 1994 of Competing for the Future, C.K. Prahalad and Gary Hamel create a new view of strategy in one overall statement developing earlier HBR concepts like foresight, strategic architecture, global pre-emption and 'the need to forget'. Then, with new ideas like opportunity space, opportunity horizon, corporate challenge, and expeditionary marketing, the authors present a new language system to capture these ideas. Interviewed in Michigan by EMJ's editor, Paul Stonham, C.K. Prahalad points first that Competing for the Future is about 'democratizing' strategy -- how to engage a large number of people in creating a strategic direction, and that managers are now receptive to exploring ways of revitalizing companies. Continuing of the corporation, profitable growth, and ability to change, are all essential criteria for competitiveness. Wealth creation involves leveraging resources and creating new investment opportunities all the time. Shareholders and investors recognize this. C.K. Prahalad has views on the cultural springs of success, on innate competitive advantage, and on acquisitions as one of a number of alternative modes to acquire competence. He declines to be drawn into a close comparison of large and small companies, but prefers to focus on entrepreneurship and innovation. He points to the decreasing unilateral role of governments in international trade and finance, and to the need for innovative companies to search the global market for managerial talent. Business schools still produce functionally-biased managers; they should concentrate in future on producing at least four skills in their potential managers: teamwork, resolution of complex conflicts, languages, and operationalizing concepts. Finally, hinting in the interview of the next phase of his work, C.K. Prahalad does not lessen the anticipation of his readers.
An Evaluation Procedure For Probability Of Fatigue Failure In Offshore Steel Catenary Risers [um Procedimento Para Avaliação Da Probabilidade De Falha Por Fadiga Em Um Riser Rígido Em Catenária]
No full textThe current work presents a procedure to evaluate the probability of fatigue failure in an offshore Steel Catenary Riser (SCR) through the identification and the assessment of the influence of involved main parameters taking into account the probability of failure. Meteocean conditions such as waves, current and platform motions, and uncertainties due to total cumulative damage (Miner-Palmgren's Rule) are considered in the procedure. The probabilistic methodology is taken, and the analytical approach based on the First Order Reliability Method (FORM) is applied. A failure function for the SCR is defined considering its structural strength and the loads acting on it. The random nature of the meteocean conditions as well as the total cumulative damage are considered to the sensitivity analysis for the probability of failure. The procedure suggested is applied for two practical cases. The first case uses data from the literature, and the second one considers data collected from a typical Brazilian offshore field operation. On both cases, the SCR are connected to a semi-submersible platform at the sea surface. The results of the probability of failure are observed for four different locations along the SCR length such as the influence of each involved parameter.211171127Pezzi Filho, M., Casaprima, E., Berry, N., Kayser, D., Simões Filho, S., Capella, M., Donato, G., Almeida, T., Desenvolvimento de metodologia para gerenciamento da integridade de SCRs baseada em risco (2007) Rio Pipeline Conference & Exposition, , Rio de Janeiro, RJ, oct(2002) DNV-RP-G101: Risk Based Inspection of Offshore Topsides Static Mechanical Equipment, , DET NORSKE VERITAS Norway(2001) DNV-RP-F107: Risk Assessment of Pipeline Protection, , DET NORSKE VERITAS NorwayAng, A.H.-S., Tang, W.H., (1984) Probability Concepts in Engineering Planning and Design, 2. , Canada: John Wiley & Sons IncSagrilo, L.V.S., Lima, E.C.P., Uma estratégia computacional para análise de confiabilidade de plataformas offshore fixas (1995) CILAMCE, Congresso Ibero Latino Americano Sobre Métodos Computacionais para Engenharia, , Curitiba, Brasil, nov.-dezAkpan, U.O., Koko, T.S., Rushton, P.A., Tavassoli, A., Else, M., Probabilistic fatigue reliability of large diameter steel catenary risers (SCR) for ultra-deepwater operations (2007) OMAE-29556, Proceedings of 26th International Conference on Offshore Mechanics and Arctic Engineering, , San Diego, California, USA, JunXia, J.K., Das, P.K., Probabilistic fatigue reliability analysis of deepwater steel catenary risers (2008) OMAE2008-57178, Proceedings of 27th International Conference on Offshore Mechanics and Arctic Engineering, , Estoril, Portugal, JunBay, Y., (2003) Marine Structural Design, , Oxford: Elsevier Science(1992) DNV-CN-30.6: Structural Reliability Analysis of Marine Structures, , DET NORSKE VERITAS NorwayMorooka, C.K., Idehara, A.Y., Matt, C.G.C., In line and cross-flow behavior of a free-spanning pipeline (2007) OMAE2007-29195, Proceedings of 26th International Conference on Offshore Mechanics and Arctic Engineering, , San Diego, California, USA, JunTorres, A.L.F.L., Mourelle, M.M., Silva, R.M.C., Fatigue damage verification of steel catenary risers (2001) OMAE2001/OFT-1261, Proceedings of 20th International Conference on Offshore Mechanics and Arctic Engineering, , Rio de Janeiro, Brazil, JunMelchers, R.E., (1999) Structural Reliability Analysis and Predictions, , 2. ed.

Decommissioning Offshore Production Facilities
No full textDecommissioning offshore oil and gas production facilities have been progressively increasing the concern of the industry, government and other interest groups through the last years. There are at least two reasons for this sudden regard. First, it is the maturing of several oil and gas fields around the world in recent years. Second, it is the growing impact of environmental concerns in international affairs. Despite several works published address to some techniques and to potential problems and risks related to decommissioning offshore oil and gas production installations its procedures are in some extent an innovative issue, especially in Brazil. Therefore, the motivation of this paper is the novelty of the subject in Brazil, since the national industry is just beginning to deal with the end-of-leasing obligations, which involve decommissioning operations. The main ambition is to stimulate debate about appropriate issues.1467474Thornton, W., The cost denial (1998) Oil and Gas Journal, 58 (11)Shell, U.K., Brent spar dossier: The story, photographic record, feature stories, press releases and technical data www.shell.com/uk-en/directory/0,4010,25268,00.html, [On-line][01/2001]Meenan, P., Technical aspects of decommissioning offshore structures article from Decommissioning Offshore Structures, SPRINGER-VERLAG, London, Great Britain, 1998.

Journalistiek oriëntalisme. C.K. Elout en de transformatie van de koloniale verslaggeving in Nederland 1920–1930
No full textIn the interwar period, the leading Dutch journalist C.K. Elout conducted two research trips to the Dutch East Indies for the newspaper Algemeen Handelsblad. This article studies Elout’s letters from his travels in the context of the growing journalistic interest in the Netherlands in colonial matters in the 1920s. The reason for this interest was the increase in information transferred between the Netherlands and South-east Asia as a result of new technologies and rising tensions in the Indies due to the emergence of the anticolonial movement. Through his letters, Elout intended to stimulate colonial reporting in the Netherlands, with the goal of strengthening overseas ties. Therefore, this corpus of texts can be seen as a form of journalistic orientalism in which the author extensively reflects on the differences between the West and the East. This article focuses on these reflections and demonstrates how they influenced Elout’s later commentary on the news from the Dutch East Indies
