  • the plurality of centralizers 12 may be secured to the string 10 by any conventional means, including welding and/or one or more mechanical fasteners such as bolts, or may be formed integral to the string 10 . While the embodiment shown in FIG. 1 includes a plurality of centralizers 12 , it is to be appreciated that in some embodiments, centralizers 12 may be absent from the string 10 .
  • one or more monitoring or control lines 16 extend along the outer surface 14 of the string 10 .
  • the lines may be, for example, electrical lines, hydraulic lines, and/or fiber optic lines, or the like. Further, while four lines 16 are shown in FIG. 1 , it is to be appreciated that other quantities of lines 16 , for example one, two, or ten lines 16 are contemplated herein.
  • At least one line passage 18 is disposed along the outer surface 14 of the string 10 and extending axially along the string 10 .
  • the at least one line passage 18 may be disposed circumferentially between two centralizers 12 .

  • the at least one line passage 18 extends substantially an entire length of a joint of the string 10 . In other embodiments, however, it may be desired to utilize two or more interconnected line passages 18 arranged axially along the string 10 . In one embodiment, each line passage 18 will extend about 10 feet.
  • a first line passage 18 may interconnect to a second line passage 18 via, for example, a pin and sleeve arrangement.
  • the first line passage 18 may include a sleeve 20 at one circumferential side and a pin 22 at the other circumferential side, while the second line passage 18 may similarly include a sleeve 20 and a pin 22 .
  • the pin 22 of the first line passage 18 is engaged in the sleeve 20 of second line passage 18 and the pin 22 of the second line passage 18 is inserted into the sleeve 20 of the first line passage 18 .
  • the first line passage 18 may be configured entirely with pins 22 and the second line passage 18 may be configured entirely with sleeves 20 , or vice versa. While the pin and sleeve arrangement is illustrated in FIG. 2 , it is to be appreciated that other means of interconnecting or joining the line passages 18 may be utilized.
  • the line passages 18 may be interconnected utilizing hinges, a telescoping overlap between the ends of the two line passages 18 , and/or bolts.
  • other quantities of line passages 18 for example, three or five line passages 18 may be arranged along each joint of the string 10 .
