As offshore activities are growing, the marine operations are becoming more complex involving the presence of few or several vessels in proximity to each other which increases the risk associated to those operations. Shuttle tankers, PSVs, floatels are often equipped with DP systems for maintaining position. The capability of these systems is defined during design phase by the DP manufacturer based on the assumption of standalone operation and considering environmental load cases prescribed in Industry standards (ex. wind, wave and current all aligned). During a realistic operational condition, however, the presence of other unities may significantly alter the loads acting on the DP vessel which will affect somehow its station keeping capacity. Furthermore, in some areas of the world, the misalignment between the environmental loads and the presence of several wave trains from different directions (ex. off-shore Brazil) shall be considered in the sake of safety of the operation. In order to provide the clients means to simulate these complex operations (including moored vessels), a DP module has been integrated to Bureau Veritas multi-body mooring software, ARIANE. In this paper, the case of a DP floatel vessel operating close to a turret moored FPSO in Brazilian waters is analyzed and the differences in the DP capacity under realistic conditions with respect to the original DP capability are presented and discussed.
Este trabalho é fruto de uma pesquisa de Iniciação Científica realizada no Município de Santana que fica localizado no Oeste da Bahia. A pesquisa foi desenvolvida com base no projeto Educação do Campo no século XXI: reflexões sobre a realidade da educação para os sujeitos do campo no município de Santana-BA e teve como objetivo, analisar de que forma está organizada, em pleno Século XXI, a educação para os sujeitos do campo do referido município, em especial a partir da publicação do Decreto 7.352 de 2010, que trata da Política de Educação do Campo e do Programa Nacional de Educação na Reforma Agrária – PRONERA. Para tanto, foi necessário identificar a concepção de educação que orienta a organização da proposta pedagógica desenvolvida nas escolas do campo no município de Santana-BA; compreender como está organizada a educação para os povos do campo; analisar as políticas públicas voltadas para o fortalecimento da educação dos povos do campo e como são desenvolvidas no município em questão; construir o perfil dos educadores que trabalham nas escolas do campo; construir o perfil dos estudantes que frequentam as escolas do campo e identificar os desafios que o município enfrenta na oferta de educação para os povos do campo
