Abstract
"UMBILICAL DE LINHA DE FLUXO AQUECIDA". A presente invenção refere-se a uma instalação offshore que inclui um umbilical de linha de fluxo de óleo / gás instalado entre uma plataforma - ou uma instalação em terra - e um gabarito baseado no leito do mar e que inclui um condutor de cabo elétrico isolado conectado em série com o tubo de aço de óleo / gás a um suprimento de energia. A característica principal da invenção é que a interconexão da extremidade distante entre o condutor de cabo (ou condutores de cabo paralelos) e o tubo é aterrada na água do mar para fornecer um sistema aterrado de ponto único, de tal modo que toda a corrente flui nos condutores de cabo selecionados, e o sistema tem zero volts na extremidade distante por meio de que nenhuma corrente é transmitida através do mar. O suprimento de energia é isolado da terra e a corrente é alimentada do suprimento de energia através do tubo, e retorna através do cabo, por meio de que um nível de voltagem de zero volts é obtido na extremidade distante onde o sistema é aterrado, e toda a corrente é forçada através do(s) cabo(s) e do tubo / linha de fluxo.
