Abstract

EQUIPAMENTO ATENUADOR DE MOVIMENTOS DE DUTOS SUSPENSOS A presente invenção refere-se a um equipamento (Q) destinado a reduzir a transmissão de movimentos naturais gerados por uma unidade estacionária de produção (U), do tipo offshore, para a região em que um duto dinâmico ("riser") estabelece contato com o fundo do mar (M). O objetivo acima é alcançado com a interposição do equipamento (Q) em um trecho pré-determinada da catenária formada pelo "riser" (R). Tal equipamento (Q) tem a função de cessar a transmissão da onda de compressão dinâmica sofrida pela catenária, sem ter a função de escoamento de qualquer fluido que o "riser" (R) transporta. A interligação hidráulica entre o tramo superior (T2) e o tramo inferior (T1) é realizada por meio de um duto flexível (D), normalmente conhecido pelos especialistas como "jumper" flexível. A presente invenção tem como característica a imposição de um comportamento complacente, que desacopla significativamente o movimento imposto pela unidade estacionária de produção (U) e condições do mar e correntes marinhas do movimento resultante no "riser" (R).SUSPENDED PIPE MOVEMENT ATTENUATING EQUIPMENT The present invention relates to equipment (Q) for reducing the transmission of natural movements generated by an offshore stationary production unit (U) to the region where a dynamic pipe ("riser") establishes contact with the seabed (M). The above objective is achieved by interposing the equipment (Q) in a predetermined portion of the riser catenary (R). Such equipment (Q) has the function of ceasing the transmission of the dynamic compression wave suffered by the overhead contact line, without having the flow function of any fluid that the riser (R) carries. The hydraulic interconnection between the upper branch (T2) and the lower branch (T1) is accomplished by means of a flexible duct (D), commonly known to those skilled in the art as a flexible jumper. The present invention is characterized by the imposition of compliant behavior which significantly decouples the movement imposed by the stationary unit of production (U) and sea conditions and marine currents from the resulting movement in the riser (R).
