Abstract

resumo patente de invenção: "aperfeiçoamentos relacionados a risers sustentados por flutuabilidade". trata-se de uma boia de suporte de riser submarina que compreende um membro de suporte de riser e um membro de suporte de ponte que se estende geralmente paralelo um ao outro e que define uma direção longitudinal entre os mesmos através da boia. as docas flutuantes se estendem longitudinalmente além do membro de suporte de riser e do membro de suporte de ponte para fornecer pontos de fixação para conectar correias à boia. dessa maneira, aos pontos de fixação são espaçados mais amplamente do que as extremidades longitudinais do membro de suporte de riser e do membro de suporte de ponte, alterando de forma benéfica o comportamento dinâmico da boia e especialmente suas características de afastamento.
