Abstract

En teknikk muliggjør overføring av signaler i undersjøiske brønnapplikasjoner. Teknikken gjør det mulig å overføre et kommunikasjonssignal og et kraftsignal gjennom en eneste gjennomføring anordnet gjennom en rørhenger i et undersjøisk ventiltre. Kommunikasjonssignalet og/eller kraftsignalet blir omformet for å muliggjøre kommunikasjon langs et snodd par for overføring ned i brønnen.A technique enables the transmission of signals in subsea well applications. The technique makes it possible to transmit a communication signal and a power signal through a single throughput arranged through a pipe hanger in a subsea valve tree. The communication signal and / or power signal is reshaped to allow communication along a twisted pair for transmission down the well.
