Abstract

"DISPOSITIVO DE TUBO ASCENDENTE". Um tubo ascendente (18) se estende entre uma embarcação de superfície, por exemplo uma plataforma de perfuração (16), e um item de equipamento submarino, por exemplo, uma válvula preventiva de escape (12) no fundo do mar (10). O tubo ascendente (18) é equipado com pelo menos um impulsor, por exemplo na forma de um ou mais propulsores posicionais acionados por motor (201, 202), que está disposto de modo a ser capaz de exercer uma força impulsora essencialmente horizontal no tubo ascendente (18) a fim de contrabalançar as forças laterais das correntes oceânicas, de modo a manter o tubo ascendente (18) em uma posição que corresponde ao curso desejado da embarcação de superfície (16) para o equipamento submarino (12)."UPPER TUBE DEVICE". A riser (18) extends between a surface vessel, for example a drilling rig (16), and an item of subsea equipment, for example, a preventive escape valve (12) on the seabed (10). The riser (18) is equipped with at least one impeller, for example in the form of one or more motor-driven positional thrusters (201, 202), which is arranged to be able to exert an essentially horizontal driving force on the tube ascending (18) in order to counterbalance the lateral forces of ocean currents, in order to keep the ascending tube (18) in a position that corresponds to the desired course of the surface vessel (16) for the subsea equipment (12).
