Lankhorst VIV strake design
Lankhorst VIV Strakes are typically recognized for their perpendicular intermittent vanes, wound around the pipe in a triple helix. The pitch of these helices is equal to 16 times the pipe OD, however alternative pitches are possible. The standard Lankhorst vane height will deliver a suppression efficiency that is well beyond the generally required 90% compared to bare pipe. The drag increase is relatively low.
Optimized for installation
Lankhorst VIV suppression strakes have been designed with ease and speed of installation as a key design feature in order to minimize the expense of offshore installation time. By using the tri-shell concept, strakes are light and installation speed is optimized. Tri-shells also have a high packing density, so that the number of supply barge movements offshore and needed deck space can be kept to a minimum.
To improve on packing density, in 2020 Lankhorst developed the TriVIV 2.0. This type of Lankhorst VIV strake offers five times improved packing density, making it the ideal choice for Reel-lay applications with no load constraints. Once installed, TriVIV2.0 maintains the exact same vane configuration as the original TriVIV, ensuring identical performance and suppression efficiency. Both versions share the same rigorous qualifications and proven track record, providing reliable VIV suppression across various offshore applications.
