Abstract

profunda flutuante, auto-flutuante para uso na perfuração e produção de poços offshore. O diâmetro da seção transversal da parte inferior do caixão flutuante é menor do que o diâmetro da seção transvmetro da seção transversal reduzido da parte inferento e também aumenta o amortecimento hidrodinâmice é mantido na posição por linhas de ancoragem. O caixão flutuante tem um poço central através do qual passam os elevadores de perfuração e/ou produçãalmente abaixo dos tanques de flutuabilidade duros. As placas de aprisionamento de água e/ou fiadas de chapas helicoidais também podem ser utilizadas em conjuntos com a invenção. deep floating, self-floating for use in drilling and producing offshore wells. The diameter of the cross section of the bottom of the floating coffin is smaller than the diameter of the transveter section of the reduced cross section of the lower part and also increases the hydrodynamic damping is maintained in position by anchor lines. The floating coffin has a central well through which the drilling and / or production elevators pass below the hard buoyancy tanks. Water trapping plates and / or helicoidal layers can also be used in conjunction with the invention.
