Abstract

a presente invenção refere-se a um sistema de tubulação offshore compreendendo um primeiro tubo flexível não ligado e um segundo tubo flexível não ligado para o transporte de fluidos, tais como óleo ou gás. cada um dos tubos flexíveis não ligados compreende uma bainha de selagem e uma camada de blindagem eletricamente condutiva, e, além disso, o sistema compreende um primeiro conector terminal conectado à primeira extremidade do primeiro tubo flexível não ligado e um segundo conector terminal conectado à primeira extremidade do segundo tubo flexível não ligado. no sistema de tubulação offshore a camada de blindagem eletricamente condutiva do primeiro tubo flexível não ligado é eletricamente conectada com a camada de blindagem eletricamente condutiva do segundo tubo flexível não ligado através de uma primeira conexão elétrica e uma segunda conexão elétrica. para obter um circuito elétrico as primeira e segunda conexões elétricas são aplicadas com uma distância ao longo do comprimento do primeiro tubo flexível não ligado e o segundo tubo flexível não ligado, respectivamente. a invenção também se refere a um método para aquecimento de tubos, pela formação de um circuito elétrico entre os tubos.
