The present invention relates to Vortex Induced Vibration (VIV) suppression strakes, in particular VIV suppression strakes that are arranged on subsea pipelines. The present invention provides a VIV suppression strake assembly (9, 11), comprising a strake fin support shell (23, 25) that is configured to be arranged against the outer surface of a section of pipe and at least one strake fin (15) having a fin tip (35) and a fin base (37). The strake fin support shell (23, 25) comprises an aperture (29) that is configured for inserting the fin (15) therein, and the fin (15) is provided at the fin base with an anchor (39), which anchor is configured for engaging the fin support shell (23, 25) on the pipe side of the aperture. Further, the aperture is a slot. Furthermore, the slot is dimensioned to allow the fin (15) to be inserted in the slot from the pipe side of the slot with the fin tip (35) leading until the fin base (37) engages the shell.
