<p>A device and method for the reduction of vortex- induced vibration of a deepwater riser. A device for attachment to a structure, which is subject to movement relative to a fluid surrounding the structure, for reducing vortex- induced vibration effects on the structure, rhe device comprising: a flexible netting (4) interconnecting a plurality of relatively inflexible members comprising a plurality of elongate members (3) and a plurality of spacer members (6), wherein each elongate member has a first cuter boundary and each spacer member has a second outer boundary wherein the second boundary extends radially outward of the first outer boundary relative to the netting, over at least: a substantial portion of the boundary.</p> |
