Tri-Strakes® C is a Vortex Induced Vibration (VIV) suppression system, consisting of overlapping and interlocking moldings, with three-start helical strakes to provide an effective triangular or trapezoidal strake profile. Tri-Strakes® C combines the stackability of the Tri-Strakes® L (Lite) with the load resilience of the Tri-Stakes® Stinger.

Tri-Strakes® C has a temperature resistant up to 60°C/ 140°F, each section of the system has been designed as a single, lightweight component, enabling quick and easy pre-install onshore or install offshore. The design permits the system to be stacked efficiently during shipping, which also reduces space taken up on the vessel.

The established manufacturing process means that the Tri-Strakes® C can be produced up to three times faster than systems manufactured using traditional techniques, enduring shorter lead times.

Available with anti-foul coating or paint designed to prevent marine growth build-up, particularly in shallow water environments.
