Abstract:

Embodiments may be directed to marine geophysical surveying and associated methods. At least one embodiment may be directed to incorporation of a lock mechanism in a sensor streamer that interlocks the outer jacket with one or more of the spacers to prevent relative rotation between the outer jacket. An embodiment may provide a sensor streamer that includes an outer jacket, a plurality of spacers, and a locking mechanism. The outer jacket may be elongated in an axial direction and comprise an outer jacket surface and an inner jacket surface. The plurality of spacers may be positioned in the outer jacket at spaced apart locations in the axial direction, wherein each of the plurality of spacers comprises a spacer body having an outer spacer surface. The locking mechanism may interlock the outer jacket with at least one of the plurality of spacers.
