US Patent 7835222 Anti-biofouling seismic streamer casing and method of manufacture

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). Two parts of a two-part silicone elastomer are then mixed together (220). The method also includes coating the mixed two-part silicone elastomer on the flexible tubing (230), and heating the flexible tubing to cure the coating (240).
