Title:
TWIN-FIN FAIRING
Document Type and Number:
WIPO Patent Application WO/2016/080828
Kind Code:
A3
Abstract:
A fairing (1) for improving fluid flow around a circular-cylindrical object comprises a first fairing-element (11) and a second fairing-element (12), which are releasable relative to one another. The fairing-elements are easy to manufacture, compactly stackable, and easy to install around the object. In installed condition, the first fairing-element and the second fairing-element are mutually connected in circumferential direction of the fairing, while forming a twin-fin fairing, which reduces vortex-induced vibrations around the object, while providing favourable flow resistance, and without performing galloping motions.
