ABSTRACT:
Systems and methods for reducing vortex-induced vibration and drag about a marine element are provided. The system can include, but is not limited to, a shell rotatably mounted about the marine element, the shell having opposing edges defining a longitudinal gap configured to allow the shell to snap (be placed) around at least a portion of the marine element. A fin can be positioned along each opposing edge of the longitudinal gap, wherein each fin can extend outwardly from the shell. The fins can be positioned on the shell so as to reduce vortex-induced vibration and minimize drag on the marine element. One or more antifouling agents can be disposed on, in, or about at least a portion of the shell, the fins, or a combination thereof.
