Abstract: A method for improving a fluid dynamic profile and fouling properties of a marine vessel with a welding seam which forms a cap protruding above a surface being under the waterline of a vessel. The method comprising amending the welding seam by applying a fairing to the underwater surface, e.g. by use of filler. A vessel with a fairing, and a coating system for a vessel and including a fairing.

Abstract: A method is provided for establishing a fouling-release coating system on a surface of a substrate, as well as the fouling-release coating system per se. The fouling-release coating composition which is used in the method comprises one or more sterically hindered amines, in particular 2,2,6,6-tetraalkyl piperidine derivatives.

Abstract: The present application discloses a silicone-based fouling-release coat comprising a polysiloxane-based binder matrix constituting at least 40% by dry weight of said coat, wherein more than 65% by weight of said binder matrix is represented by polysiloxane parts, and comprising one or more poly(oxyalkylene)-modified alcohols, e.g. poly(oxyalkylene)-modified sterols, and one or more biocides. Further, the application discloses a silicone-based fouling-release coating system, wherein one or more coats comprises one or more poly(oxyalkylene)-modified alcohols, and one or more coats comprises one or more biocides, and wherein the coating system comprising 1-20 g/m2 of one or more poly(oxyalkylene)-modified alcohols and 2-35 g/m2 of one or more biocides. Also, a corresponding marine structure and a silicone-based fouling-release coating composition are disclosed.
