Title (EN) VORTEX INDUCED SUPPRESSION DEVICE
(FR) DISPOSITIF DE SUPPRESSION INDUITE PAR TOURBILLON
Abstract:
(EN) The invention relates to a vortex induced vibration suppression device (10) comprising: a riser pipe (12); a strake body (14) encircling the riser pipe (12); a vane (16) extending outwardly from the strake body (14), the vane (16) having a height (18) and a width (20); and a buffer (26) extending outwardly from the strake body (14), the buffer (26) having a height (32); wherein the height (32) of the buffer (26) is smaller than the height (18) of the vane (16) The buffer is provided to prevent damage of the vane from contact loads.
(FR) La présente invention concerne un dispositif de suppression de vibration induite par tourbillon (10) comprenant : une colonne montante (12); un corps de virure (14) encerclant la colonne montante (12); une aube (16) s'étendant vers l'extérieur depuis le corps de virure (14), l'aube (16) ayant une hauteur (18) et une largeur (20); et un tampon (26) s'étendant vers l'extérieur depuis le corps de virure (14), le tampon (26) ayant une hauteur (32); la hauteur (32) du tampon (26) étant inférieure à la hauteur (18) de l'aube (16). Le tampon est disposé pour éviter d'endommager l'aube en raison des charges de contact.
