摘要 |
An electromagnetic downlink and pickup apparatus for transmitting and receiving electromagnetic signals is disclosed. The electromagnetic downlink and pickup apparatus includes a subsea conductor (47) disposed beneath the s ea floor (16) and a surface installation (58) for generating and interpreting signals. The subsea conductor (47) and the surface installation (58) are electrical ly connecting by first and second conduits (30, 51) that form a pair terminals on the subsea conductor (47) between which a voltage potential may be established, thereby providing a path for current flow therebetween.
