imizes the possibility of alternate vortexes forming. They may be used on their own, or in conjunction with other devices such as fairings.
Strakes need not follow the entirety of the structure; vibration suppression is most evident in the areas exposed to higher flow velocities, while strakes in lower-velocity areas have less effect. Consequently, many structures are only covered in helical strakes where the vibrations are greatest; many are limited to the upper third of the structure. In deepwater structures, for instance, strakes may only cover the portion exposed to surface currents, while areas exposed to the slower waters below are left tubular.
Sections of helical strakes are generally assembled from shorter lengths. Strakes thus commonly consist of a series of segments, with the number determined by the length of the structure covered. Metal strakes are cut from larger plates to a radius of curvature informed by the number of revolutions around the stack. Conventionally, strakes have a pitch of 16 to 17.5D, though other pitches may be used.
Helical strakes are less sensitive to flow direction than alternatives such as fairings. However, they have several shortcomings. They significantly increase mean drag, and as a result loading is increased. Strakes are less effective under a certain mass-damping parameter. Strakes have reduced effectiveness when flow is turbulent. Strakes likewise are less effective when located downstream from eac
