Abstract
A fiber optic sensor assembly for use on a sub-sea pipeline. The fiber optic sensor assembly is coupled to remotely located equipment by fiber optic cable(s) which extend outside of the pipeline. The fiber optic sensor assembly is affixed to a mounting point on the pipeline. The mounting point is a pipe section having an internal conduit and at least one layer that surrounds the internal conduit for protection and insulation of the internal conduit. A segment of the pipe section has a portion of such layer(s) removed or omitted to define an annular recess. When installed, the assembly has two semi-cylindrical halves that are positioned with the annular recess and coupled together to thereby surround and embrace the segment of the pipe section. The assembly houses a length of optical fiber that is coupled to at least one externally accessible fiber optic connector.
