A kit of parts to form a VIV suppression strake assembly , comprising - a strake fin support shell that is configured to be arranged against the outer surface of a section of pipe; and - at least one strake fin having a fin tip and a fin base ; wherein - the strake fin support shell comprises an aperture that is configured for inserting the fin therein; and wherein - the fin is provided at the fin base with an anchor , which anchor is configured for engaging the fin support shell , wherein the aperture is a slot , CHARACTERIZED IN THAT - the slot extends through the fin support shell from a pipe side through to a fin side opposite the pipe side of the fin support shell and is dimensioned to allow the strake fin to either be inserted in the slot from the pipe side of the slot with the fin tip leading until the fin base engages the pipe side of the fin support shell surrounding the slot , or be inserted in the slot from the fin side of the slot with the fin base in a deformed insertion state leading until the fin base passes the through going slot to deploy into an original extended state on the pipe side of the fin support shell surrounding the slot , whereby the anchor at the fin base is engaged by the pipe side of the fin support shell to prevent the strake fin from moving out of the slot in the direction of the fin side. - a strake fin support shell that is configured to be arranged against the outer surface of a section of pipe; and - at least one strake fin having a fin tip and a fin base ; wherein - the strake fin support shell comprises an aperture that is configured for inserting the fin therein; and wherein - the fin is provided at the fin base with an anchor , which anchor is configured for engaging the fin support shell , wherein the aperture is a slot , CHARACTERIZED IN THAT - the slot extends through the fin support shell from a pipe side through to a fin side opposite the pipe side of the fin support shell and is dimensioned to allow the strake fin to either be inserted in the slot from the pipe side of the slot with the fin tip leading until the fin base engages the pipe side of the fin support shell surrounding the slot , or be inserted in the slot from the fin side of the slot with the fin base in a deformed insertion state leading until the fin base passes the through going slot to deploy into an original extended state on the pipe side of the fin support shell surrounding the slot , - the slot extends through the fin support shell from a pipe side through to a fin side opposite the pipe side of the fin support shell and is dimensioned to allow the strake fin to either be inserted in the slot from the pipe side of the slot with the fin tip leading until the fin base engages the pipe side of the fin support shell surrounding the slot , or be inserted in the slot from the fin side of the slot with the fin base in a deformed insertion state leading until the fin base passes the through going slot to deploy into an original extended state on the pipe side of the fin support shell surrounding the slot , whereby the anchor at the fin base is engaged by the pipe side of the fin support shell to prevent the strake fin from moving out of the slot in the direction of the fin side. <EOS>
