A conductor or casing orientation sensor housing 6 includes circular or arched walls 7 embedded within the wall of the conductor 3. The circular or arched walls are disposed about and separated from said orientation sensor 8 by at least one shock absorbing frame 9, spring 10, moveable bearing arrangement (11, fig 10), gelatinous material (12, fig 10) or protective stabiliser (48, fig 16), which also provide continuous ultrasonic or electrical contact with said conductor for transmission of a signal through the conductor wall while also inhibiting stresses transmitted to said orientation sensor during said conductor's installation. In a second aspect a method of placing an orientation sensor housing within a conductor is provided. |
