Abstract

Patente de Invenção:<B>''MéTODO E DISPOSITIVO PARA AJUSTAR A FLUTUAçãO DE UM ELEVADOR DE TUBULAçãO DE PERFURAçãO OFFSHORE". A presente invenção refere-se a um elevador para ferramenta de perfuração ou broca, de fonte subaquática, compreendendo elementos tubulares (1) unidos através de dispositivos de conexão (2). Os elementos compreendem um dispositivo de flutuação consistindo de um recipiente (6), para o interior do qual pode ser bombeado um determinado volume de gás, de tal forma a modificar a peso aparente do elemento na água. - Pelo menos um elemento tubular compreende meios (12) para a medição da diferença de pressão entre o interior e o exterior do referido recipiente, meios (14) para preencher o recipiente com gás, meios (15) para descarregar o gás do recipiente, meios (13) para controlar os meios de enchimento e os meios de descarga considerando a medição de diferença de pressão. - A invenção ainda se refere a um método para ajustar a flutuação de um elemento de elevação de tubulação. - A Figura 1 a ser divulgada.
