Title (EN) SYSTEM FOR REDUCING VORTEX INDUCED VIBRATION OF A MARINE ELEMENT
(FR) SYSTEME DE REDUCTION DE VIBRATION INDUITE PAR EFFET VORTEX SUR UN ELEMENT NAVAL
Abstract: front page image
(EN)A strake system (12) is provided for protecting a cylindrical marine element (6) from vortex induced vibration. The strake system (12) comprises at least two shell members (16A, 16B) forming a hollow cylinder defining a cylindrical hollow passage for receiving the marine element (6), the hollow cylinder being provided with a strake extending along the outer surface of the hollow cylinder so as to reduce vortex induced vibrations of the marine element.
(FR)L'invention concerne un système de virure (12) protégeant un élément naval cylindrique (6) contre les vibrations induites par effet vortex. Ce système (12) comprend au moins deux coques (16A, 16B) formant un passage cylindrique creux qui permet de recevoir l'élément naval (6). Le cylindre creux comporte une virure qui s'étend le long de sa surface externe, de manière à réduire les vibrations induites par effet vortex sur l'élément naval.
