Abstract

A STRAKE SYSTEM (12) IS PROVIDED FOR PROTECTING A CYLINDRICAL MARINE ELEMENT FROM VORTEX INDUCED VIBRATION. THE STRAKE SYSTEM (12) COMPRISES AT LEAST TWO SHEEL MEMBERS (16A, 16B) FORMING A HOLLOW CYLINDER DEFINING A CYLINDRICAL HOLLOW PASSAGE FOR RECEIVING THE MARINE ELEMENT, THE HOLLOW CYLINDER BEING PROVIDED WITH A STRAKE (14) EXTENDING ALONG THE OUTER SURFACE OF THE HOLLOW CYLINDER SO AS TO REDUCE VORTEX INDUCED VIBRATIONS OF THE MARINE ELEMENT.FIG. 2
