1. A Cable Assembly for supplying power, comprising:

  • an elongated cable body having a length of from several meters to several kilometers, the cable body comprising in combination;

    wiring for carrying alternating electrical current;

    a plurality of Source Inductive Elements spaced at intervals along the wiring to provide power by induction, and the spacing of the plurality Source Inductive Elements creating distinct induction sites, along the length of the cable body, capable of providing power by induction to a plurality of distinct power consuming nodes located at spaced intervals; and

    an encapsulation layering that provides electrical insulation;

    a monitoring system having a plurality of Monitoring Nodes, each of the Monitoring Nodes is powered by inductive coupling of a Sink Inductive Element to one of said Source inductive Elements, and each of the Monitoring Nodes monitors signals from at least one sensor, the at least one sensor including a chemical sensor for detecting hydrocarbons.
