  • Anti-biofouling seismic streamer casing and method of manufacture
    Patent number: 7835222
    Abstract: An anti-biofouling seismic streamer casing (100,100?) is provided that is formed by a flexible tubing (110) coated with a layer of a two-part heat cured silicone elastomer (120). The seismic streamer casing (100, 100?) is formed by a method that includes steps of providing a flexible tubing (200) and pre-treating the outer surface of the tubing (210).
