A method of deploying a cable in a pipeline, according to claim 12, including the step of employing, as said cable, a fiber optic cable. 14. A method of deploying a cable in a pipeline, according to claim 12, including the step of employing, as said cable, a fiber optic cable providing distributed temperature measurement in said pipeline. 15. A method of deploying a cable in a pipeline according to claim 12, including the step of providing lateral flanges on said pig at forward and rearward ends thereof, said flanges being adapted to stabilise it and guide it in the pipeline and allow it to be driven forward by pipeline fluid. 16. A method of deploying a cable in a pipeline according to claim 12 wherein the enclosure is located on a rearward end of the pig. 17. A method of deploying a cable in a pipeline according to claim 16 wherein the enclosure is flexibly connected to the pig, whereby to articulate the pig and enclosure assembly for use in a curved pipeline. 18. A method of deploying a cable in a pipeline according to claim 12 wherein the launcher includes an inlet for fluid for driving the pig along the pipeline. 19. A method of deploying a cable in a pipeline according to claim 12 wherein the coil is a static coil made up of multiple layers of cylindrical windings. 20. An assembly of pipeline cable deployment apparatus and a pipeline comprising a pipeline pig having, in use, forward and rearward ends, said pig carrying an enclosure containing a coil of cable, the enclosure having an exit for the cable rearwardly of the pig, wherein the pig has a body and means extending laterally therefrom for positioning the pig in the pipeline, the enclosure being located within the pig body and the laterally extending means comprising lateral flanges of lesser width than a diameter of an inside of the pipeline at the forward and rearward ends for stabilizing it and guiding it in the pipeline and for allowing it to be driven forward by pipeline fluid. 21. The assembly according to claim 20, wherein said enclosure is operative to contain a cable cassette of diameter 180 mm, length 150 mm, and capable of containing 2000 m of 0.85 mm diameter cable. 22. An assembly of pipeline cable deployment apparatus and a pipeline comprising a pipeline pig having, in use, forward and rearward ends, said pig carrying an enclosure containing a coil of cable, the enclosure having an exit for the cable rearwardly of the pig, wherein the pig has a body and means extending laterally therefrom for positioning the pig in the pipeline, the enclosure being located within the pig body and the laterally extending means comprising lateral flanges of lesser width than a diameter of an inside of the pipeline at the forward and rearward ends for stabilizing it and guiding it in the pipeline and for allowing it to be driven forward by pipeline fluid, the pipeline being circular, said flanges having a diameter of 235 mm and said pipeline having an internal diameter of 244 mm. 23. The combination of pipeline cable deployment apparatus and a pipeline, the pipeline cable deployment apparatus comprising a pipeline pig having, in use, forward and rearward ends, said pig having a body within which an enclosure containing a coil of cable is carried, the enclosure having an exit for the cable rearwardly of the pig, wherein the pig body has a smaller cross-section than an interior cross-section of the pipeline, providing a path for pipeline fluid therebetween and has flanges of lesser width than a diameter of an inside of the pipeline at forward and rearward ends thereof extending laterally outwardly around an entire outside of the pig to a location adjacent an interior wall of the pipeline into said path to obstruct flow of pipeline fluid along said path for enabling the pig to be driven forward by the pipeline fluid and for stabilizing the pig and guiding it in the pipeline.
