Vibration Protection System

The Tri-Strakes Combi from Trelleborg is a vortex-induced vibration suppression system for risers and pipelines. It consists of overlapping and interlocking moldings with three-start helical strakes to provide a triangular of trapezoidal strake profile. The system is temperature resistant up to 140°F, and it is available with anti-foul coating or paint designed to prevent the build-up of marine growth, particularly in shallow water environments.
