1. A biofouling resistant seismic streamer assembly, comprising:

  • a flexible tubing seismic streamer casing having an external surface coated with a layer of a silicone elastomer such that the silicone elastomer remains connected to the seismic streamer casing to provide biofouling resistance during prolonged use of the seismic streamer assembly as a seismic streamer;

    a plurality of acoustic signal receiving sensors within the seismic streamer casing; and

    a buoyancy material within the seismic streamer casing;

    wherein said biofouling resistant flexible tubing is formed by a process comprising the steps of;

    a. providing a flexible tubing;

    b. optionally pressurizing said flexible tubing;

    c. treating the surface of the flexible tubing to be coated;

    d. mixing the silicone elastomer;

    e. coating said mixed silicone elastomer on said flexible tubing; and

    ,f. heat curing said silicone elastomer coated on said flexible tubing.
