Abstract

"TUBO ASCENDENTE COM SERVIçOS INTERNOS RECUPERáVEIS". São descritos sistemas para elevar fluido de produção a partir de uma fonte (1) no leito do mar compreendendo um tubo ascendente (4) que tem uma primeira extremidade inferior para conexão ou conectada à fonte; um suporte de extremidade de topo para suportar o tubo ascendente em ou na proximidade da superfície do mar; e um dispositivo de operação (11) montado dentro do tubo ascendente (4) para deslocamento dentro do tubo ascendente tal que a bomba seja acessível a um operador para substituição ou reparo. O dispositivo de operação (11) pode ser deslocado em um tubo (12) que se estende dentro do tubo ascendente (4) e até uma extremidade inferior a que o dispositivo (11) é preso. O dispositivo (11) pode ser, entre outras coisas, uma bomba elétrica, uma bomba hidráulica, um injetor de gás, um aquecedor ou um dispositivo de limpeza."RISE PIPE WITH RECOVERABLE INTERNAL SERVICES". Systems for raising production fluid from a seabed source (1) comprising a riser (4) having a first lower end for connection to or connected to the source are described. a top end bracket for supporting the riser at or near the sea surface; and an operating device (11) mounted within the riser (4) for displacement within the riser such that the pump is accessible to an operator for replacement or repair. The operating device (11) may be moved into a tube (12) extending within the riser (4) and to a lower end to which the device (11) is attached. The device 11 may be, among other things, an electric pump, a hydraulic pump, a gas injector, a heater or a cleaning device.
