    ANTI-BIO FLAWING COATING FOR A SEISMIC FLOATING CABLE. An anti-biofouling coating for a seismic float cable is provided, the coating comprising an outer film, the outer film comprising a mixture of a base material and a molecular additive, wherein the molecular additive is located along the base material , and the molecular additive is configured to impart a high contact angle and/or low surface energy to an outer surface of the anti-biofouling coating to prevent the adhesion of living organisms thereto. The outer film may comprise a coating/film for a seismic float rope such that the film of the float rope contains a base material with a hydrophobic molecular additive distributed throughout the film of the float rope.

    ANTI-BIO FLAWING COATING FOR A FLOATING CABLE
    SEISMIC Background Biofouling, the attachment of marine species to marine equipment and vessels, can cause serious problems for marine operations. With regard to marine seismic survey, biofouling, which is generally barnacle fouling/fixation, is a costly problem for the seismic industry. For example, towing float ropes, encrusted with marine species such as barnacles, as illustrated in Figure 1, can result in higher fuel consumption for the tow vessel due to the higher induced drag/turbulent flow. In addition, the heavily encrusted mass of float ropes can result in sections of float rope snapping under the resulting tension. Also, before float ropes are wound back onto vessels, after operations, marine species, barnacles etc. adhered must be physically removed. This removal process is a mechanical, time-consuming and manual release process, which can
